Description

L'invention concerne un système de calendrier horloger. Elle concerne aussi un mouvement horloger comprenant un tel système de calendrier. Elle concerne enfin une pièce d'horlogerie, notamment une montre bracelet, comprenant un tel système ou un tel mouvement.The invention relates to a horological calendar system. It also relates to a watch movement comprising such a calendar system. Finally, it relates to a timepiece, in particular a wristwatch, comprising such a system or such a movement.

Le brevet EP2428856B1 divulgue un dispositif d'affichage de l'indication des mois dans lequel la décalque d'un disque des mois est prévue pour coopérer avec l'un des douze guichets du cadran. Bien que visuellement instantané, le mécanisme est entraîné en plusieurs étapes, ce qui minimise et répartit l'énergie nécessaire au saut du mois sur plusieurs jours, et permet ainsi de garantir la précision chronométrique de la montre. Même si cet affichage permanent de l'indication des mois est particulièrement discret, celui-ci nécessite toutefois une esthétique bien particulière du cadran de la pièce d'horlogerie.The patent EP2428856B1 discloses a device for displaying the indication of the months in which the decal of a month disc is provided to cooperate with one of the twelve apertures of the dial. Although visually instantaneous, the mechanism is driven in several stages, which minimizes and distributes the energy necessary to jump the month over several days, and thus makes it possible to guarantee the chronometric precision of the watch. Even if this permanent display of the month indication is particularly discreet, it nevertheless requires a very particular aesthetic of the dial of the timepiece.

Le brevet CH681673B5 propose un dispositif d'affichage ponctuel d'une information horaire dans lequel un organe d'affichage électro-optique est prévu pour apparaître, à la demande du porteur, dans une fenêtre du disque des quantièmes ou du disque des jours, qui est disposée entre deux informations calendaires. Dans un mode de réalisation préféré, l'information masquée correspond au numéro du mois, celui-ci pouvant par exemple apparaître lors du réglage d'un calendrier annuel ou perpétuel. Ce dispositif a pour avantage d'être particulièrement discret. En contrepartie, celui-ci requiert des moyens d'actionnement complexes qui doivent être programmés de telle sorte qu'ils puissent permettre l'entraînement sur un ou deux pas angulaires du disque des quantièmes ou des jours selon la position angulaire de la fenêtre. Ce sont, par exemple, des moyens électroniques. Par ailleurs, aucune liaison cinématique n'est proposée entre les disques des quantièmes ou des jours et l'organe d'affichage, ce dernier étant fixe.The patent CH681673B5 proposes a one-off display device for time information in which an electro-optical display member is provided to appear, at the request of the wearer, in a window of the date disc or of the day disc, which is arranged between two calendar information. In a preferred embodiment, the masked information corresponds to the number of the month, the latter possibly appearing for example when setting an annual or perpetual calendar. This device has the advantage of being particularly discreet. In return, this requires complex actuation means which must be programmed in such a way that they can allow the drive over one or two angular steps of the date or day disc depending on the angular position of the window. These are, for example, electronic means. Moreover, no binding kinematics is not offered between the date or day discs and the display member, the latter being fixed.

La demande de brevet EP0987609 décrit un mécanisme de calendrier annuel qui est doté d'une première chaîne cinématique d'entraînement du disque des quantièmes et d'une seconde chaîne de correction du disque des quantièmes qui est pilotée sous l'actionnement d'une came des mois. A cet effet, le disque des quantièmes présente trois dentures distinctes. Une première denture, formée de trente et une dents, est prévue pour être entraînée classiquement par un mobile entraîneur des quantièmes. Une deuxième denture, formée d'une dent, est prévue pour être entraînée par un mobile de correction des quantièmes. Une troisième denture, formée d'une dent, est prévue pour entraîner une came des mois portant un organe d'affichage permanent de l'indication des mois lors du passage du trente et unième quantième d'un mois en cours au premier quantième du mois suivant.The patent application EP0987609 describes an annual calendar mechanism which is provided with a first kinematic drive chain for the date disc and with a second date disc correction chain which is controlled by actuation of a month cam. To this end, the date disc has three distinct teeth. A first set of teeth, formed by thirty-one teeth, is designed to be driven conventionally by a date-driving mobile. A second set of teeth, formed by a tooth, is provided to be driven by a date correction wheel. A third set of teeth, formed of a tooth, is provided to drive a months cam carrying a permanent display member of the month indication when the thirty-first calendar of a current month passes to the first date of the month. following.

La demande de brevet EP1666991 divulgue un mécanisme de calendrier annuel traînant qui est doté d'une roue des mois prévue pour être entraînée à la fin d'un mois court par une dent additionnelle du disque des quantièmes lors du passage du trente au « trente et un », et par un doigt additionnel du mobile des quantièmes lors du passage du « trente et un » au premier quantième du mois suivant. Cette solution présente l'avantage de mettre en oeuvre un disque des quantièmes particulièrement simple, doté uniquement de deux jeux de denture distincts. Toutefois, un tel séquencement requiert un mécanisme complexe, dans lequel l'entraînement de la roue des mois est rendu possible par le fait que le calendrier est traînant. L'entraînement synchronisé de chacun des éléments, notamment du disque des quantièmes et de la roue des mois, conduirait en effet au blocage du dispositif. Ainsi, il n'est pas possible de parvenir à la mise en oeuvre d'un calendrier annuel à saut de date instantané sur la base d'un tel mécanisme. Par ailleurs, la roue des mois porte un organe d'affichage permanent de l'indication des mois. Le double saut de la roue des mois requiert le dédoublement de l'indication des mois et donc un rapetissement de l'indicateur des mois, ce qui peut créer un effet inesthétique au niveau du cadran. Le document US4228644A montre un système de calendrier horloger selon le préambule de la revendication 1.The patent application EP1666991 discloses a dragging annual calendar mechanism which is provided with a months wheel intended to be driven at the end of a short month by an additional tooth of the date disc when changing from thirty to thirty-one, and by an additional finger of the date mobile when changing from “thirty-one” to the first date of the following month. This solution has the advantage of using a particularly simple date disc, provided only with two distinct sets of teeth. However, such a sequencing requires a complex mechanism, in which the driving of the month wheel is made possible by the fact that the calendar is dragging. The synchronized drive of each of the elements, in particular of the date disc and of the month wheel, would indeed lead to blocking of the device. Thus, it is not possible to achieve the implementation of a annual calendar with instantaneous date jump on the basis of such a mechanism. Furthermore, the month wheel carries a permanent display member for the month indication. The double jump of the month wheel requires the doubling of the month indication and therefore a shortening of the month indicator, which can create an unsightly effect on the dial. The document US4228644A shows a watch calendar system according to the preamble of claim 1.

Le but de l'invention est de fournir un système de calendrier permettant de remédier aux inconvénients mentionnés précédemment et d'améliorer les dispositifs de calendriers horlogers connus de l'art antérieur.

De préférence, l'invention concerne un système de calendrier dont le dispositif d'affichage de l'indication des mois est doté d'un organe d'affichage de l'indication des mois qui présente la spécificité de n'être visible du porteur que de manière ponctuelle, par exemple lors de l'affichage d'un quantième particulier, notamment pour les phases de réglage du système de calendrier.Preferably, the invention relates to a calendar system in which the device for displaying the indication of the months is provided with a device for displaying the indication of the months which has the specific feature of only being visible to the wearer. ad hoc, for example during the display of a particular date, in particular for the adjustment phases of the calendar system.

Le système de calendrier présente notamment la particularité d'entraîner, au moins partiellement, l'organe d'affichage de l'indication des mois entre le premier et le trente et unième quantième d'un mois en cours.The calendar system has the particular feature of driving, at least partially, the display member for the indication of the months between the first and the thirty-first calendar of a current month.

Un tel système propose une alternative avantageuse aux dispositifs d'affichage permanent de l'indication des mois qui peuvent surcharger le cadran d'une pièce d'horlogerie. Un tel système permet par ailleurs de simplifier la construction d'un mouvement du type quantième annuel ou quantième perpétuel. Dans un mode de réalisation particulier, le système permet également de minimiser et de répartir l'énergie requise à l'entraînement de l'organe d'affichage de l'indication des mois ou d'une came des mois.Such a system offers an advantageous alternative to devices for the permanent display of the month indication which can overload the dial of a timepiece. Such a system also makes it possible to simplify the construction of a movement of the annual calendar or perpetual calendar type. In a particular embodiment, the system also makes it possible to minimize and distribute the energy required for driving the display member of the month indication or of a month cam.

De préférence donc, dans le système de calendrier, l'organe d'affichage des mois est visible uniquement dans une configuration prédéterminée de l'organe d'affichage des quantièmes, par exemple le premier d'un mois donné, et/ou l'organe d'affichage des mois est entraîné, au moins partiellement, entre le premier et le trente et unième quantième d'un mois en cours.Preferably therefore, in the calendar system, the month display member is visible only in a predetermined configuration of the date display member, for example the first of a given month, and / or the month display member is driven, at least partially, between the first and the thirty-first calendar of a current month.

Un tel affichage ponctuel de l'indication des mois a en effet pour avantage de permettre une désynchronisation au moins partielle du mobile d'affichage des mois vis-à-vis du mobile d'affichage des quantièmes, ce qui peut simplifier et/ou optimiser la construction d'un système de calendrier à quantième annuel ou perpétuel dans lequel le mobile des mois est lié cinématiquement au mobile des quantièmes, en particulier dans lequel le mobile des mois est uniquement lié cinématiquement au mobile des quantièmes. Un tel système de calendrier permet notamment de proposer une structure du mobile des quantièmes particulièrement simple dans laquelle le mobile est doté uniquement de deux jeux de denture distincts.Such a one-off display of the month indication has the advantage of allowing at least partial desynchronization of the month display mobile vis-à-vis the calendar display mobile, which can simplify and / or optimize the construction of a calendar system with an annual or perpetual calendar in which the mobile of the months is kinematically linked to the mobile of the dates, in particular in which the mobile of the months is only kinematically linked to the mobile of the dates. Such a calendar system makes it possible in particular to provide a particularly simple calendar structure in which the mobile is provided only with two distinct sets of teeth.

Les dessins annexés représentent, à titre d'exemples, deux modes de réalisation de systèmes de calendriers horlogers selon l'invention.

  • Les figures 1 à 10 représentent un premier mode de réalisation d'un système de calendrier horloger illustratif n'étant pas selon l'invention.
  • Les figures 11 à 15 représentent un deuxième mode de réalisation d'un système de calendrier horloger selon l'invention.
The appended drawings represent, by way of examples, two embodiments of watch calendar systems according to the invention.
  • The figures 1 to 10 show a first embodiment of an illustrative horological calendar system not according to the invention.
  • The figures 11 to 15 show a second embodiment of a watch calendar system according to the invention.

Un premier aspect est illustré par un premier mode de réalisation d'une pièce d'horlogerie 120 qui est décrit ci-après en référence aux figures 1 à 10. La pièce d'horlogerie est par exemple une montre bracelet.A first aspect is illustrated by a first embodiment of a timepiece 120 which is described below with reference to figures 1 to 10 . The timepiece is for example a wristwatch.

La pièce d'horlogerie peut comprendre un mouvement horloger 110, notamment un mouvement mécanique.The timepiece may include a watch movement 110, in particular a mechanical movement.

Le mouvement horloger comprend un premier mode de réalisation d'un système de calendrier 100 selon l'invention. Avantageusement, le système de calendrier est du type à quantième annuel, voire à quantième perpétuel.The watch movement comprises a first embodiment of a calendar system 100 according to the invention. Advantageously, the The calendar system is of the type with an annual calendar, or even a perpetual calendar.

Le système 100 de calendrier horloger comprend :

  • un organe d'affichage 10 des quantièmes comprenant une ouverture 10a ; et
  • un organe d'affichage 30 des mois agencé de sorte à afficher une indication de mois dans l'ouverture 10a, notamment lorsque l'ouverture 10a est visible par un utilisateur du système de calendrier et/ou lorsque le système de calendrier indique le premier quantième d'un mois donné.
The 100 watch calendar system includes:
  • a date display member 10 comprising an opening 10a; and
  • a display member 30 of the months arranged so as to display a month indication in the opening 10a, in particular when the opening 10a is visible to a user of the calendar system and / or when the calendar system indicates the first date of a given month.

De préférence, l'ouverture 10a est un premier guichet en vis-à-vis d'une indication de quantième ou juxtaposée à une indication de quantième, en particulier en vis-à-vis du quantième « 1 » ou juxtaposée au quantième « 1 ». Dans le premier mode de réalisation décrit, l'ouverture 10a est donc juxtaposée à l'indication du premier quantième. Il est bien entendu possible de disposer l'ouverture 10a en regard d'un autre quantième.Preferably, the opening 10a is a first window facing a date indication or juxtaposed with a date indication, in particular facing the date “1” or juxtaposed with the date “1”. ". In the first embodiment described, the opening 10a is therefore juxtaposed with the indication of the first date. It is of course possible to have the opening 10a facing another date.

De préférence encore, l'organe d'affichage 30 des mois ou organe indicateur des mois est agencé de sorte à afficher une indication de mois dans l'ouverture 10a lorsque le système de calendrier indique le premier quantième d'un mois donné.More preferably, the month display member 30 or month indicator member is arranged so as to display a month indication in the opening 10a when the calendar system indicates the first date of a given month.

Dans le premier mode de réalisation, le mobile d'affichage des mois est actionné sur un seul et unique pas angulaire du disque des quantièmes effectué entre le premier et le trente et unième quantième d'un mois en cours.In the first embodiment, the month display mobile is actuated on a single angular step of the date disc made between the first and the thirty-first calendar of a current month.

Le premier mode de réalisation présente la particularité d'être doté d'un mobile 1 des quantièmes qui comporte une première denture extérieure 1a prévue pour coopérer avec une denture 2a d'un ensemble 2 de programmation. Le mobile 1 des quantièmes présente une denture 1b qui se réduit à une dent 1b prévue pour coopérer à la fois avec une denture 2b de l'ensemble de programmation 2 comme représenté sur la figure 2 et avec une denture 3a d'un mobile 3 des mois comme représenté sur la figure 3. Les dentures 1a et 1b sont ici disposées sur deux niveaux distincts.The first embodiment has the particularity of being provided with a date wheel set 1 which comprises a first external toothing. 1a designed to cooperate with a set of teeth 2a of a programming assembly 2. The date wheel set 1 has a set of teeth 1b which is reduced to a tooth 1b provided to cooperate both with a set of teeth 2b of the programming assembly 2 as shown in FIG. figure 2 and with a set of teeth 3a of a mobile 3 months as shown in figure 3 . The teeth 1a and 1b are here arranged on two distinct levels.

L'organe 10 d'affichage des quantièmes ou organe indicateur des quantièmes est disposé au dessus de l'organe 30 indicateur des mois. Ainsi, l'indication des mois n'est pas visible de l'utilisateur à travers une glace de la pièce d'horlogerie et notamment à travers un second guichet 4 réalisé par exemple dans un cadran 99 (représenté partiellement sur la figure 6), tant que l'ouverture 10a formée sur l'organe 10 n'est pas disposée en vis-à-vis du second guichet 4 comme représenté sur la figure 4. Pour ce faire, le système de calendrier horloger peut inclure le cadran muni du second guichet d'affichage des quantièmes dans lequel l'ouverture est agencée pour apparaître.The date display member 10 or date indicator member is arranged above the month indicator member 30. Thus, the indication of the months is not visible to the user through a glass of the timepiece and in particular through a second window 4 made for example in a dial 99 (shown partially in the figure. figure 6 ), as long as the opening 10a formed on the member 10 is not disposed vis-à-vis the second window 4 as shown in FIG. figure 4 . To do this, the horological calendar system can include the dial provided with the second date display window in which the opening is arranged to appear.

Durant les phases d'immobilisation des mobiles 1 et 3, ces derniers sont indexés classiquement par le biais de sautoirs 5, 6, dont les becs 5a, 6a sont respectivement prévus pour coopérer avec les dentures 1a et 3a comme représenté sur la figure 3.During the immobilization phases of the mobiles 1 and 3, the latter are indexed conventionally by means of jumpers 5, 6, the jaws 5a, 6a of which are respectively provided to cooperate with the teeth 1a and 3a as shown in Figure figure 3 .

L'ensemble 2 est agencé de sorte que le système de calendrier distingue les mois courts des mois longs. A cet effet, les dentures 2a, 2b de l'ensemble 2 sont toutes deux prévues pour être actionnées, tous les jours, par un élément 7 d'entraînement du système de calendrier doté de deux doigts d'entraînement 7a, 7b qui sont chacun dédiés à l'entraînement des dentures 2a, 2b. Le doigt 7b actionne la denture 2b par l'intermédiaire d'une denture 2c, ces deux dentures 2b et 2c étant solidaires en rotation grâce à une goupille 200 comme représenté sur la figure 5.Set 2 is arranged so that the calendar system distinguishes short months from long months. To this end, the teeth 2a, 2b of the assembly 2 are both designed to be actuated, every day, by a drive element 7 of the calendar system provided with two drive fingers 7a, 7b which are each dedicated to driving the teeth 2a, 2b. The finger 7b actuates the toothing 2b by means of a toothing 2c, these two toothings 2b and 2c being integral in rotation by means of a pin 200 as shown in figure 5 .

L'interaction entre une dent de la denture 2a de l'ensemble 2 et une dent de la denture 1a du mobile 1 se produit lors de chaque changement de quantième. Par contre, l'interaction entre une dent de la denture 2b de l'ensemble 2 et la dent 1b du mobile 1 ne se produit qu'à la fin de chaque mois court, plus particulièrement lors de la transition d'affichage du trentième au « trente et unième » quantième de chaque mois court. A titre d'exemple, les figures 6 à 8 illustrent le mécanisme à la fin du mois de novembre. La figure 6 représente l'état du système de calendrier lors de la transition d'affichage du trentième au « trente et unième quantième ». Dans cette configuration, le doigt 7b mène la denture 2b qui actionne la dent 1b sur un premier pas angulaire du mobile des quantièmes. La figure 7 représente l'état du système de calendrier lors de la transition d'affichage du trente et unième quantième au premier quantième du mois de décembre. Dans cette configuration, le doigt 7a mène la denture 2a qui actionne la denture 1a sur un second pas angulaire du mobile des quantièmes. Ainsi, pour une action, notamment un tour, de l'élément 7 d'entraînement du système de calendrier, le mobile 1 des quantièmes a avancé de deux pas, de même que l'organe d'affichage 10 des quantièmes qui est passé d'un état affichant « 30 » à un état affichant « 1 ». En conséquence, le système comprend au moins une dent 1b du mobile 1 des quantièmes agencée pour permettre un saut additionnel de l'organe 10 d'affichage des quantièmes à la fin d'un mois de trente jours. La figure 8 illustre l'état final du système de calendrier après les deux transitions décrites plus haut.The interaction between a tooth of the set of teeth 2a of the assembly 2 and a tooth of the set of teeth 1a of the mobile 1 occurs during each date change. On the other hand, the interaction between a tooth of the teeth 2b of the assembly 2 and the tooth 1b of the mobile 1 only occurs at the end of each short month, more particularly during the display transition from the thirtieth to the “Thirty-first” calendar of each short month. For example, figures 6 to 8 illustrate the mechanism at the end of November. The figure 6 represents the state of the calendar system during the display transition from the thirtieth to the “thirty-first date”. In this configuration, the finger 7b drives the teeth 2b which actuates the tooth 1b on a first angular pitch of the date wheel set. The figure 7 represents the state of the calendar system during the display transition from the thirty-first date to the first date of the month of December. In this configuration, the finger 7a drives the teeth 2a which actuates the teeth 1a on a second angular pitch of the date wheel set. Thus, for an action, in particular a turn, of the driving element 7 of the calendar system, the date wheel set 1 has moved forward by two steps, as has the date display member 10 which has moved past 'a state displaying "30" to a state displaying "1". Consequently, the system comprises at least one tooth 1b of the date wheel set 1 arranged to allow an additional jump of the date display member 10 at the end of a month of thirty days. The figure 8 illustrates the final state of the calendar system after the two transitions described above.

Durant ces phases de changement de date en fin de mois, on remarque que le mobile 3 des mois, en particulier l'organe 30 d'affichage des mois, reste immobile. On remarque que dans la séquence de fonctionnement illustrée par les figures 6 à 8, le mobile 3 des mois a été préalablement positionné de telle manière que l'organe 30 d'affichage des mois peut indiquer l'affichage correspondant au mois du premier quantième indiqué par l'organe 10. A titre d'exemple, la figure 8 représente la configuration du système de calendrier en date du premier décembre. Dans cette configuration, le porteur de la montre est informé du mois en cours le premier de chaque mois, notamment pour un éventuel réglage du système de calendrier.During these date change phases at the end of the month, it is noted that the month mobile 3, in particular the month display unit 30, remains stationary. Note that in the operating sequence illustrated by figures 6 to 8 , the month mobile 3 has been positioned beforehand in such a way that the month display member 30 can indicate the display corresponding to the month of the first date indicated by the member 10. By way of example, the figure 8 represents the calendar system configuration as of December 1st. In this configuration, the wearer of the watch is informed of the current month on the first of each month, in particular for a possible adjustment of the calendar system.

L'actionnement du mobile 3 des mois est effectué en cours de mois lorsque la dent 1b vient agir sur la denture 3a, plus particulièrement lors du passage du onzième au douzième quantième d'un mois en cours comme illustré sur les figures 9 et 10. Dans un souci de clarté, les quantièmes « 10 », « 11 » et « 12 » ne sont pas représentés sur le disque 10 d'affichage des quantièmes. Avantageusement, le déplacement de l'organe 30 d'affichage des mois n'est pas visible du porteur de la montre étant donné que l'ouverture 10a n'est pas positionnée dans le second guichet 4 du cadran 99. Ainsi, selon ce mode de réalisation, à partir du douzième quantième d'un mois en cours, le mobile 3 des mois est positionné de telle manière que l'organe 30 d'affichage des mois puisse indiquer le mois qui suivra, comme représenté sur la figure 10. En conséquence, un élément 1 d'entraînement du mobile des mois est agencé de sorte que le mobile des mois ou l'organe d'affichage des mois est entraîné alors que l'organe d'affichage des mois et/ou l'ouverture 10a n'est pas visible par l'utilisateur. En particulier, l'élément d'entraînement est agencé de sorte que le mobile des mois ou l'organe d'affichage des mois est entraîné entre le deuxième et le trentième quantième indiqué par le système de calendrier, en particulier entre le dixième et le vingtième quantième indiqué par le système de calendrier.The actuation of the mobile 3 of the months is carried out during the month when the tooth 1b acts on the toothing 3a, more particularly during the passage from the eleventh to the twelfth calendar of a current month as illustrated in the figures. figures 9 and 10 . For the sake of clarity, the dates "10", "11" and "12" are not represented on the date display disc 10. Advantageously, the movement of the month display member 30 is not visible to the wearer of the watch given that the opening 10a is not positioned in the second window 4 of the dial 99. Thus, according to this mode implementation, from the twelfth calendar of a current month, the month mobile 3 is positioned in such a way that the month display member 30 can indicate the month which will follow, as shown in the figure. figure 10 . Consequently, a driving element 1 of the month mobile is arranged so that the month mobile or the month display member is driven while the month display member and / or the opening 10a is not visible to the user. In particular, the driving element is arranged so that the mobile of the months or the month display member is driven between the second and the thirtieth date indicated by the calendar system, in particular between the tenth and the month. twentieth date indicated by the calendar system.

De préférence encore, l'élément d'entraînement de l'organe d'affichage des mois est agencé pour entraîner d'un pas l'organe d'affichage des mois alors que l'organe d'affichage des quantièmes est entraîné d'un pas.More preferably, the driving element of the month display member is arranged to drive the month display member by one step while the date display member is driven by one step. not.

L'élément d'entraînement est avantageusement le mobile des quantièmes. Il comprend au moins une dent 1b coopérant avec plusieurs dents 3a du mobile 3 des mois, en particulier une dent 1b coopérant avec douze dents 3a du mobile 3 des mois.The drive element is advantageously the date mobile. It comprises at least one tooth 1b cooperating with several teeth 3a of the mobile 3 of the months, in particular a tooth 1b cooperating with twelve teeth 3a of the mobile 3 of the months.

Un tel mode de réalisation permet la mise en oeuvre d'un mobile des quantièmes simplifié, doté uniquement de deux niveaux distincts pour l'agencement des dentures 1a, 1b. Il en découle également une conception plus compacte, avec une épaisseur de module de calendrier minimisée. Alternativement, la denture 1b pourrait être agencée sur un même niveau que la denture 1a par le biais d'une géométrie de denture 1b se distinguant de celle de la denture 1a.Such an embodiment allows the use of a simplified date mobile, provided only with two distinct levels for the arrangement of the teeth 1a, 1b. This also results in a more compact design, with a minimized calendar module thickness. Alternatively, the toothing 1b could be arranged on the same level as the toothing 1a by means of a toothing geometry 1b which differs from that of the toothing 1a.

Un deuxième mode de réalisation d'une pièce d'horlogerie 220 est décrit ci-après en référence aux figures 11 à 15. La pièce d'horlogerie est par exemple une montre bracelet.A second embodiment of a timepiece 220 is described below with reference to figures 11 to 15 . The timepiece is for example a wristwatch.

La pièce d'horlogerie peut comprendre un mouvement horloger 210, notamment un mouvement mécanique.The timepiece may include a watch movement 210, in particular a mechanical movement.

Le mouvement horloger comprend un deuxième mode de réalisation d'un système de calendrier 200 selon l'invention. Avantageusement, le système de calendrier est du type à quantième annuel, voire à quantième perpétuel.The watch movement comprises a second embodiment of a calendar system 200 according to the invention. Advantageously, the calendar system is of the type with an annual calendar, or even a perpetual calendar.

Le système 200 de calendrier horloger comprend :

  • un organe d'affichage 10 des quantièmes comprenant une ouverture 10a ; et
  • un organe d'affichage 30 des mois agencé de sorte à afficher une indication de mois dans l'ouverture 10a.
The watch calendar system 200 includes:
  • a date display member 10 comprising an opening 10a; and
  • a month display member 30 arranged so as to display a month indication in the opening 10a.

Les éléments des premier et deuxième modes de réalisation du système de calendrier ayant la même structure ou la même fonction sont référencés par les mêmes signes numériques.The elements of the first and second embodiments of the calendar system having the same structure or the same function are referenced by the same numerals.

Le premier aspect de l'invention est aussi illustré par le deuxième mode de réalisation décrit ci-après. Ce deuxième mode de réalisation se distingue principalement du premier mode de réalisation décrit plus haut en ce que :

  • le mobile des mois est entraîné d'un pas sur plusieurs pas d'entraînement du mobile des quantièmes ; et/ou
  • l'organe d'affichage des quantièmes et l'organe d'affichage des mois sont pivotés autour d'un même axe P, soit de manière coaxiale, et/ou le mobile des quantièmes et le mobile des mois sont pivotés autour d'un même axe P, soit de manière coaxiale.
The first aspect of the invention is also illustrated by the second embodiment described below. This second embodiment differs mainly from the first embodiment described above in that:
  • the month mobile is driven by one step over several driving steps for the date mobile; and or
  • the date display member and the month display member are rotated around the same axis P, either coaxially, and / or the date mobile and the months mobile are pivoted around a same axis P, or coaxially.

Dans le deuxième mode de réalisation, le mobile d'affichage des mois est ainsi actionné sur plusieurs pas angulaires du disque des quantièmes comme représenté sur les figures 11 à 13. Le système de calendrier comporte notamment un élément de liaison cinématique 8 entre le mobile des quantièmes et le mobile des mois. Par exemple, cet élément de liaison peut être réalisé sous forme d'un mobile intermédiaire ou sous forme d'un système dans lequel un ou plusieurs renvois engrènent d'une part avec le mobile des quantièmes, au moins sur un secteur denté du mobile des quantièmes, et engrènent d'autre part avec le mobile des mois. En fonctionnement conventionnel du système de calendrier, la position angulaire du mobile des quantièmes peut être indexée par le biais d'un sautoir 5 dont la tête 5a est prévue pour coopérer avec une denture du mobile des quantièmes. La position angulaire du mobile des mois 3 est, quant à elle, garantie, aux jeux de dentures près, via l'élément de liaison qui coopère avec le mobile des quantièmes et le mobile des mois.In the second embodiment, the month display mobile is thus actuated over several angular steps of the date disc as shown in the figures. figures 11 to 13 . The calendar system comprises in particular a kinematic link element 8 between the date set and the month set. For example, this connecting element can be produced in the form of an intermediate mobile or in the form of a system in which one or more references mesh on the one hand with the date mobile, at least on a toothed sector of the date mobile. dates, and on the other hand mesh with the mobile of the months. In conventional operation of the calendar system, the angular position of the calendar mobile can be indexed by the bias of a jumper 5 whose head 5a is designed to cooperate with a toothing of the date wheel set. The angular position of the month mobile 3 is, for its part, guaranteed, except for the toothing clearances, via the connecting element which cooperates with the date mobile and the months mobile.

Le mobile 1 des quantièmes présente une denture intérieure 1a prévue pour être actionnée par un doigt 7a entraîneur des quantièmes. Dans le mode de réalisation représenté, le mobile des quantième comprend en outre une denture 1b disposée à la périphérie extérieure du mobile 1 et qui est prévue pour coopérer avec une denture 3a du mobile 3 des mois par le biais de l'élément de liaison cinématique 8. L'élément de liaison est pivoté autour d'un axe parallèle à l'axe P.The date wheel set 1 has internal teeth 1a designed to be actuated by a finger 7a which drives the dates. In the embodiment shown, the date mobile further comprises a set of teeth 1b disposed at the outer periphery of the mobile 1 and which is designed to cooperate with a set of teeth 3a of the mobile 3 by means of the kinematic connection element. 8. The connecting element is rotated about an axis parallel to the P axis.

L'élément de liaison 8 peut par exemple comprendre une croix de Malte 8 comme représenté sur les figures 11 à 13. La croix de Malte peut comprendre des saillies 8a coopérant avec n dents 1b du mobile des quantièmes. La croix de Malte présente une denture 8b coopérant par engrenage avec une denture 3a du mobile 3 des mois. n est de préférence un entier naturel supérieur à 1, notamment n=2 ou n=3 ou n=4 ou n=5. Ainsi, l'élément de liaison 8 est agencé pour entraîner d'au plus 1/n pas le mobile des mois alors que l'organe d'affichage des quantièmes est entraîné d'un pas.The connecting element 8 may for example comprise a Maltese cross 8 as shown in the figures 11 to 13 . The Maltese cross can include projections 8a cooperating with n teeth 1b of the date wheel set. The Maltese cross has a set of teeth 8b cooperating by gear with a set of teeth 3a of the mobile 3 of the months. n is preferably a natural number greater than 1, in particular n = 2 or n = 3 or n = 4 or n = 5. Thus, the connecting element 8 is arranged to drive at most 1 / n step the month mobile while the date display member is driven by one step.

En fonctionnement conventionnel du système de calendrier, la position angulaire du mobile 1 est indexée par le biais d'un sautoir 5 dont la tête 5a est prévue pour coopérer avec la denture 1a. La position angulaire du mobile 3 est, quant à elle, garantie, aux jeux de dentures près, par une périphérie circulaire extérieure 1c du mobile 1, qui est prévue pour coopérer avec un profil polygonal ou sensiblement polygonal 8c de l'élément de liaison 8. L'actionnement du mobile des mois est opéré par l'engrènement de la denture 1b avec une denture 8a de l'élément de liaison 8, ainsi que par l'engrènement de la denture 8b avec la denture 3a. En conséquence, lors de certains pas du mobile des quantièmes, le mobile des mois est entraîné de 1/n pas au plus et lors d'autres pas du mobile des quantièmes, le mobile des mois n'est pas entraîné.In conventional operation of the calendar system, the angular position of the mobile 1 is indexed by means of a jumper 5 whose head 5a is provided to cooperate with the teeth 1a. The angular position of the mobile 3 is, for its part, guaranteed, apart from the sets of teeth, by an outer circular periphery 1c of the mobile 1, which is designed to cooperate with a polygonal or substantially polygonal profile 8c of the connecting element 8 . The month mobile is operated by the engagement of the toothing 1b with a toothing 8a of the connecting element 8, as well as by the engagement of the toothing 8b with the toothing 3a. Consequently, during certain steps of the date mobile, the month mobile is driven by at most 1 / n and during other steps of the date mobile, the month mobile is not driven.

Dans le mode de réalisation représenté, le mobile des quantièmes présente quatre dents 1b. Un saut de quantième entraîne le mobile 3 des mois sur un quart de son pas angulaire, quand une dent 1b interagit avec l'élément de liaison. Toutefois, un saut de quantième n'entraîne pas le mobile 3 des mois, quand aucune dent 1b n'interagit avec l'élément de liaison. Autrement dit, le mobile des mois est actionné sur quatre pas angulaires du disque des quantièmes. Par exemple, ces actionnements ou entraînements ont lieu lors des passages du deuxième au troisième quantième, du dixième au onzième quantième, du dix-septième au dix-huitième quantième et du vingt-cinquième au vingt-sixième quantième, qui sont affichés dans le guichet 4 du cadran 99 (représenté partiellement sur la figure 13). Alternativement, le mobile 3 des mois peut être actionné sur tout le mois, à savoir sur trente et un pas angulaires du mobile des quantièmes, grâce à une structure idoine du mobile des quantièmes, du mobile des mois et de l'élément de liaison.In the embodiment shown, the date wheel set has four teeth 1b. A date jump drives the month mobile 3 over a quarter of its angular pitch, when a tooth 1b interacts with the connecting element. However, a date jump does not involve the mobile 3 of the months, when no tooth 1b interacts with the connecting element. In other words, the month mobile is actuated on four angular steps of the date disc. For example, these actuations or drives take place during passages from the second to the third date, from the tenth to the eleventh date, from the seventeenth to the eighteenth date and from the twenty-fifth to the twenty-sixth date, which are displayed in the window. 4 of dial 99 (partially shown on figure 13 ). Alternatively, the month mobile 3 can be operated throughout the month, namely over thirty-one angular steps of the date mobile, by virtue of a suitable structure of the date mobile, the month mobile and the connecting element.

Ainsi, dans ce deuxième mode de réalisation, l'énergie nécessaire au passage du mois peut être répartie sur plusieurs sauts de quantièmes instantanés, et ce, sans sautoir additionnel. L'énergie consacrée au changement de l'indication du mois est donc très faible et n'a pas d'influence négative sur la précision de la montre.Thus, in this second embodiment, the energy necessary for the passage of the month can be distributed over several instantaneous date jumps, without additional jumper. The energy devoted to changing the month indication is therefore very low and has no negative influence on the precision of the watch.

Comme dans le premier mode de réalisation, l'indication des mois n'est de préférence pas visible à travers le guichet 4, tant que l'ouverture 10a formée sur l'organe 10 n'est pas disposée dans le guichet 4. Dans le deuxième mode de réalisation, l'ouverture 10a est juxtaposée à l'indication du premier quantième « 1 » comme représenté sur les figures 11 à 13.As in the first embodiment, the indication of the months is preferably not visible through the window 4, as long as the opening 10a formed on the member 10 is not disposed in the window 4. In the window 4. second embodiment, the opening 10a is juxtaposed with the indication of the first date "1" as shown in the figures. figures 11 to 13 .

La construction illustrée par les figures 11 à 13 permet en outre de dégager le centre du mouvement, qui peut être dédié à l'affichage d'une autre indication horaire ou calendaire.The construction illustrated by figures 11 to 13 also allows clearing the center of the movement, which can be dedicated to the display of another time or calendar indication.

Dans les différents modes de réalisation, le mobile 3 des mois peut être solidaire d'une came des mois ou came de programmation 300 de calendrier annuel ou perpétuel comme illustré sur les figures 14 et 15. La came et le mobile des mois peuvent former un ensemble monobloc ou venir d'une même pièce. Alternativement, la came et le mobile peuvent être rapportés l'un sur l'autre. Une telle construction dans laquelle la came et le mobile des mois sont solidaires peut être particulièrement utile pour un système de calendrier annuel ou perpétuel dont la came de programmation, de part la structure même du système, ne peut être actionnée lors du passage du trente et unième quantième d'un mois donné au premier quantième du mois suivant. Avantageusement, la came est une came annulaire. La came des mois peut inclure un organe d'affichage ou d'indication des mois, en particulier un disque d'affichage des mois. Alternativement, la came des mois est solidaire d'un organe d'affichage ou d'indication des mois, en particulier d'un disque d'affichage des mois. La came des mois peut être dotée d'une surface de came disposée en périphérie intérieure ou extérieure.In the various embodiments, the month mobile 3 may be secured to a months cam or programming cam 300 for an annual or perpetual calendar as illustrated in the figures. figures 14 and 15 . The cam and the month mobile can form a single unit or come from the same part. Alternatively, the cam and the mobile can be attached to one another. Such a construction in which the cam and the mobile of the months are integral can be particularly useful for an annual or perpetual calendar system whose programming cam, due to the very structure of the system, cannot be actuated during the passage of the thirty-second. first date of a given month on the first date of the following month. Advantageously, the cam is an annular cam. The month cam may include a month display or indication member, in particular a month display disc. Alternatively, the month cam is integral with a month display or indication member, in particular a month display disc. The month cam may be provided with a cam surface disposed at the inner or outer periphery.

Ainsi, l'organe d'affichage 30 des mois et la came 300 de programmation de calendrier peuvent être entraînés simultanément ou ensemble.Thus, the month display member 30 and the calendar programming cam 300 can be driven simultaneously or together.

A titre d'exemple, la figure 15 représente un mécanisme d'indexation en position du mobile des quantièmes utilisant une came 300 des mois prévue pour distinguer les mois courts constitués d'au plus de trente jours des mois longs constitués de trente et un jours. Dans ce mécanisme, une bascule 9 d'indexation et d'entraînement du disque des quantièmes est pilotée en position par la came 300, par l'intermédiaire d'un premier galet 9a pivoté sur la bascule, de manière à ce qu'un deuxième galet 9b pivoté sur la bascule puisse être positionné ou non sur la trajectoire d'une denture 1d d'indexation du disque des quantièmes. Ainsi, lorsque le deuxième galet intercepte la trajectoire de la denture 1d, à la fin d'un mois court, la denture d'indexation est active et un sautoir 91 d'indexation du disque des quantièmes n'est pas actif. Il s'ensuit que, lorsque le mobile des quantièmes est positionné pour indiquer « 30 » et qu'un doigt d'entraînement agit sur le mobile des quantièmes pour l'entraîner, la coopération de la bascule et de la denture est telle que le quantième suivant indiqué de manière stable par le disque des quantièmes est « 1 ». Par contre, lorsque le deuxième galet n'intercepte pas la trajectoire de la denture 1d, à la fin d'un mois long, la denture d'indexation 1d n'est pas active et le sautoir 91 d'indexation du disque des quantièmes est actif. Il s'ensuit que, lorsque le mobile des quantièmes est positionné pour indiquer « 30 » et qu'un doigt d'entraînement agit sur le mobile des quantièmes pour l'entraîner, la coopération du sautoir 91 et de la denture 1a est telle que le quantième suivant indiqué de manière stable par le disque des quantièmes est « 31 ».For example, the figure 15 represents an indexing mechanism in position of the calendar mobile using a month cam 300 intended to distinguish short months consisting of no more than thirty days from long months consisting of thirty-one days. In this mechanism, a rocker 9 for indexing and driving the date disc is controlled in position by the cam 300, via a first roller 9a pivoted on the rocker, so that a second roller 9b pivoted on the rocker may or may not be positioned on the path of a toothing 1d for indexing the date disc. Thus, when the second roller intercepts the trajectory of the toothing 1d, at the end of a short month, the indexing toothing is active and a jumper 91 for indexing the date disc is not active. It follows that, when the date wheel set is positioned to indicate "30" and a drive finger acts on the date wheel set to drive it, the cooperation of the lever and the teeth is such that the The next date indicated stably by the date disc is "1". On the other hand, when the second roller does not intercept the trajectory of the toothing 1d, at the end of a long month, the indexing toothing 1d is not active and the jumper 91 for indexing the date disc is active. It follows that, when the date wheel set is positioned to indicate "30" and a drive finger acts on the date wheel set to drive it, the cooperation of the jumper 91 and the teeth 1a is such that the next date indicated stably by the date disc is "31".

Dans l'exemple illustré par la figure 15, la bascule 9, prévue pour coopérer avec la came 300, est pivotée sur le bâti d'un mouvement horloger. Alternativement, la bascule 9 peut par exemple être pivotée sur un mobile horloger, par exemple un mobile des quantièmes.In the example illustrated by figure 15 , the rocker 9, designed to cooperate with the cam 300, is pivoted on the frame of a watch movement. Alternatively, the rocker 9 can for example be pivoted on a watch mobile, for example a date mobile.

Dans l'exemple illustré par la figure 15, la bascule 9 est prévue pour coopérer avec une denture 1d du mobile des quantièmes.In the example illustrated by figure 15 , the rocker 9 is designed to cooperate with a set of teeth 1d of the date wheel set.

Alternativement, la bascule 9 peut se présenter sous la forme d'une denture escamotable du mobile des quantièmes prévue pour coopérer avec un élément entraîneur additionnel du mobile des quantièmes.Alternatively, the rocker 9 can be in the form of a retractable toothing of the date wheel set designed to cooperate with an additional driving element of the date wheel set.

Dans l'exemple de la figure 15, la bascule 9 est prévue pour coopérer avec la périphérie extérieure de la came 300. Bien entendu, la bascule 9 peut coopérer avec la périphérie intérieure de la came 300.In the example of figure 15 , the rocker 9 is provided to cooperate with the outer periphery of the cam 300. Of course, the rocker 9 can cooperate with the inner periphery of the cam 300.

Ainsi, la came des mois est agencée de sorte à définir :

  • un premier état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée de deux pas du mobile des quantièmes ; et
  • un deuxième état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée d'un pas du mobile des quantièmes.
Thus, the month cam is arranged so as to define:
  • a first state of the calendar system in which, while the date mobile is in position to indicate the date “30”, an action of the drive element 7 of the calendar system causes the mobile of the calendar to move two steps forward. dates; and
  • a second state of the calendar system in which, while the date mobile is in position to indicate the date "30", an action of the drive element 7 of the calendar system causes the mobile to move forward by one step dates.

Autrement dit, l'invention porte également sur un procédé de fonctionnement d'un système de calendrier horloger ou d'un mouvement horloger ou d'une pièce d'horlogerie dans lequel le procédé comprend les étapes suivantes :

  • Positionner la came des mois dans une première position définissant un premier état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée de deux pas du mobile des quantièmes ; et
  • Positionner la came des mois dans une deuxième position définissant un deuxième état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée d'un pas du mobile des quantièmes.
In other words, the invention also relates to a method of operating a watch calendar system or a watch movement or a timepiece in which the method comprises the following steps:
  • Position the months cam in a first position defining a first state of the calendar system in which, while the date wheel set is in position to indicate the date "30", an action of the drive element 7 of the calendar system. calendar causes the mobile of the dates to move two steps forward; and
  • Position the months cam in a second position defining a second state of the calendar system in which, while the date wheel set is in position to indicate the date "30", an action of the drive element 7 of the calendar system. calendar causes the date mobile to move forward by one step.

Selon le deuxième aspect de l'invention illustré par le deuxième mode de réalisation du système de calendrier, le système 200 de calendrier horloger comprend de préférence :

  • le mobile 1 des quantièmes ;
  • la came des mois 300 ; et
  • l'élément 8 de liaison cinématique agencé de sorte que le mobile des quantièmes permette l'entraînement en mouvement de la came des mois.
According to the second aspect of the invention illustrated by the second embodiment of the calendar system, the horological calendar system 200 preferably comprises:
  • date mobile 1;
  • the cam of months 300; and
  • the kinematic link element 8 arranged so that the date wheel set allows the movement of the month cam to be driven.

Préférentiellement, l'entraînement en mouvement de la came des mois est exclusivement opéré par le mobile 1 des quantièmes. Plus particulièrement, l'entraînement en mouvement de la came des mois est de préférence exclusivement opéré par le mobile 1 des quantièmes par l'intermédiaire de l'élément 8 de liaison cinématique.Preferably, the movement of the month cam is driven exclusively by the date wheel set 1. More particularly, the movement of the month cam is preferably driven exclusively by the date wheel set 1 via the kinematic link element 8.

Comme vu précédemment, le mobile des quantièmes peut comprendre l'organe d'affichage ou d'indication des quantièmes, en particulier le disque d'affichage des quantièmes.As seen above, the date wheel set may include the date display or indication member, in particular the date display disc.

De même, le mobile des mois peut comprendre l'organe d'affichage ou d'indication des mois, en particulier le disque d'affichage des mois.Likewise, the mobile of the months can include the display or indication member for the months, in particular the month display disc.

L'élément de liaison cinématique est de préférence agencé pour permettre l'entraînement, notamment l'entraînement exclusif, de la came des mois d'un pas, en particulier d'un douzième de tour, au cours d'un mois. En particulier, l'élément de liaison cinématique peut être agencé pour permettre l'entraînement de la came des mois d'au plus 1/n pas alors que le mobile des quantièmes est entraîné d'un pas, avec n un entier naturel supérieur à 1, notamment n=2 ou n=3 ou n=4 ou n=5.The kinematic connecting element is preferably arranged to allow the driving, in particular the exclusive driving, of the cam months of a step, especially a twelfth of a turn, in the course of a month. In particular, the kinematic connecting element can be arranged to allow the driving of the month cam of at most 1 / n step while the date wheel set is driven by one step, with n a natural number greater than 1, in particular n = 2 or n = 3 or n = 4 or n = 5.

Comme vu précédemment, l'élément de liaison cinématique peut comprendre un dispositif de renvois coopérant par engrenage avec la came des mois et coopérant par engrenage avec le mobile des quantièmes.As seen above, the kinematic connecting element may comprise a return device cooperating by gear with the month cam and cooperating by gear with the date wheel set.

Dans les différents modes de réalisation, le mobile des quantièmes et l'organe d'affichage ou d'indication des quantièmes peuvent former un ensemble monobloc ou venir d'une même pièce. Alternativement, l'organe et le mobile peuvent être rapportés l'un sur l'autre. De même, le mobile des mois et l'organe d'affichage ou d'indication des mois peuvent former un ensemble monobloc ou venir d'une même pièce. Alternativement, l'organe et le mobile peuvent être rapportés l'un sur l'autre.In the various embodiments, the date wheel set and the date display or indication member may form a single unit or come from the same part. Alternatively, the organ and the mobile can be attached to one another. Likewise, the mobile of the months and the display or indication member for the months can form a single unit or come from the same part. Alternatively, the organ and the mobile can be attached to one another.

Dans les différents modes de réalisation, l'ouverture 10a formée sur cet organe 10 peut bien entendu consister en une zone transparente du même organe, notamment une première zone transparente intégrée au sein d'une deuxième zone plus étendue translucide ou opaque. Pour une pièce d'horlogerie dénuée de cadran, notamment une pièce d'horlogerie de type « squelette », l'ouverture 10a se suffit à elle-même pour rendre visible l'indication du mois.In the various embodiments, the opening 10a formed on this member 10 can of course consist of a transparent zone of the same member, in particular a first transparent zone integrated within a second more extensive translucent or opaque zone. For a timepiece without a dial, in particular a timepiece of the “skeleton” type, the opening 10a is sufficient in itself to make the indication of the month visible.

Dans les différents modes de réalisation, l'indication du premier quantième « 1 », ou de tout autre quantième prévu pour être affiché avec l'indication du mois, peut, par ailleurs, être portée par l'organe 30 d'affichage des mois.In the various embodiments, the indication of the first date "1", or of any other date intended to be displayed with the indication of the month can, moreover, be carried by the month display member 30.

Préférentiellement, un système de calendrier selon l'invention est accompagné d'un système de correction rapide. Un tel système de calendrier peut également être doté d'un mécanisme laissant apparaître l'ouverture 10a uniquement en mode de réglage du système de calendrier, par exemple en fonction de la position axiale de la tige de réglage du mouvement horloger.Preferably, a calendar system according to the invention is accompanied by a rapid correction system. Such a calendar system can also be provided with a mechanism allowing the opening 10a to appear only in the mode of adjusting the calendar system, for example as a function of the axial position of the adjusting rod of the watch movement.

Dans les différents modes de réalisation, le système de calendrier horloger est de préférence du type à saut instantané.In the various embodiments, the horological calendar system is preferably of the instantaneous jump type.

Dans les différents modes de réalisation, l'organe d'affichage des quantièmes et/ou l'organe d'affichage des mois sont de préférence des disques ou des portions annulaires de disques. Alternativement, l'un et/ou l'autre des organes d'affichage peuvent comprendre une aiguille destinée à coopérer avec un limbe.In the various embodiments, the date display member and / or the month display member are preferably disks or annular portions of disks. Alternatively, one and / or the other of the display members can comprise a needle intended to cooperate with a blade.
