Description

The present invention relates to a control mechanism for Integration in a watch with a main setting device that has at least two Snap-in positions, a rest position and at least one pulled position, has, and is determined with at least one adjuster, and Watches of any type that are suitable for their integration and one have such a control mechanism, in particular a world clock analogue display of the time and an associated location in different Time zones with a shift relative to local time of a multiple of one whole or half an hour, which is a simultaneous, unequivocal reading which allows times in the displayed time zones.

Purpose-like watches have been around since the introduction of world time zones in the Following the meridian conference in Washington / USA in 1884 in a variety and diversity in terms of design and functions. These clocks often have in addition to the central minutes and Hour hands have at least one other hand that shows the time in the selected time zone, some of which are means of identifying the displayed time zone are provided, such as a permanent imprint, a rotatable ring with written world locations or the like.

For example, in the patent specification FR 2,672,399 a world clock with a additional analog display showing the time in one of the local time displays different time zone. This watch can also have another, concentrically arranged pointer, which the display of a representative location for the selected time zone and by means of a pusher can be placed in different positions. To display several However, this realization is not suitable for additional world times.

The patent specification CH 665.930 describes a world time clock with at least one additional display, the additional time information being provided by, in the given case, three sub-dials which are not arranged concentrically to the central main dial, each with an hour hand which rotates in 24 hours. Each of these additional ones
Time displays are assigned a location display in the form of a world location disc similar to a date disc and a separate crown with two positions. The latter allows you to set the time and the world location according to the desired time zone independently of the other time displays in the associated additional display. In addition, this watch has a main crown with three positions, the rest position for winding the watch, a pulled position for setting the time display of the main dial or, if a button is pressed, all dials, and a middle position for setting the date. However, the setting of the additional time displays in particular is complicated and slow, inter alia, by using crowns.

Patent EP 0 558 756 also relates to a world clock with at least one an additional analog display for the time in different world time zones. Again, sub-dials are not concentric around the central one Main dial arranged, and a three-position crown allows that Winding up the clock, setting the date and simultaneously setting the time all time displays in their undrawn position or in the first as well as second drawn position. For easy adjustment of the additional Time displays each have a pusher, the time of each Press adjusted by one hour. However, the lack of these complicates additional time displays associated with location displays, which the identification the time zone displayed would allow the zone time to be read in These ads are significant, particularly due to the presence of several additional ads. Furthermore, the pushers are always usable and can therefore easily lead to an unwanted adjustment Keep time display.

However, none of the applications mentioned has a simple and effective control of the various adjustment devices on these complex Watches on what while performing the various functions of the Watch for unwanted adjustment or possibly even damage can lead to the clockwork.

The aim of the present invention is to avoid the above Disadvantages and the creation of a control mechanism that allows the Main adjuster and the adjuster among themselves control that the functions of the main adjuster except the Winding up the watch in its rest position does not coincide with that of Auxiliary adjusters can be run, and thus creating of clocks integrating this control mechanism, especially one World clock for analog display of the time and an associated location in different time zones with a shift relative to local time of one Multiples of an entire or half an hour, which is a simultaneous, permissible unambiguous reading of the times in the displayed time zones, and the in particular, simple, quick and safe operation and setting allowed and prevents accidental adjustment of the watch.

The object of the present invention are therefore one of those in the Claims 1 and / or characteristics mentioned in the dependent claims excellent control mechanism as well as those from claim 6 defined clocks.

The invention will now be described with reference to the accompanying figures, which exemplify an embodiment of the invention in detail to be discribed.

The world clock 1 shown in FIG. 1 is characterized by a modular structure. Here, a mechanical module includes one Main dial to show the different zone times and any other displays most functions of the watch. It is based on a separate work a basic work in the form of a mechanical, quartz - controlled or automatic quartz-controlled base work can be present, mountable, so that the following explanations refer to all of these possible combinations can relate.

As can also be seen from FIG. 1, a is located in the center Main dial 2 an analog main time display 4 with hours-19, minutes-20 and second hand 21, the hour hand 19 two revolutions per Day on the main dial 2, which is preferably in a 12-division 8 makes and the second hand 21 of the main display is optional. Usually the local time is shown in the main display 4, but it can also be the Zone time of any other world location important for the wearer is shown become. Another option is a date indicator 7, which in this If the date window 24 formed in the main dial 2 is visible through it, which at a certain distance from the center 27 of the main dial 2 and in Relative to the other display elements cheap, otherwise arbitrary Angle is attached there. As usual, the date is switched with the Main time display 4 at midnight. It is also located on the outer edge of the Main dial 2 is a world ring 17, also known as Réhaut, on which important world locations 6 or useful abbreviations representative of one Time zone in a 24 division 9 of the ring 17 are attached.

Several, in the example described here three, sub-dials 3 are not concentric and their centers 28 are preferred, at least on one Side, equidistant from each other on a circle around the center 27 of the main dial 2 arranged. These sub-dials 3 have preferably also each have a 12 division 8 and a world location ring 18 there in a 24 division 9 labels of world locations 6, where both can be designed in a variety of ways analogous to main dial 2 can. Each of these sub-dials 3 is used for an analog off-time display 5, which has an hour hand 22 and a minute hand 23 for displaying the time and a world place hand 15 which at normal movement of the watch is at rest and in 24 steps for one turn an adjustment device 12 can be moved to identify the displayed one Time zone. Optionally, a secondary time display 5 can also be a day / night indicator 10, where then, for example, one in six sectors divided disc under the sub-dial turns once in 72 hours and through a day-night display window 25, the wearer receives information in advance about the morning or evening entry. Otherwise it is possible to give the subdials 3 a 24 division and thereby the hour absolute in the displayed time zone. The time is now in any time zone that is a multiple of an hour relative to local time is shifted, as well as the simultaneous and easy identification of this time zone possible.

In addition, the time zones with a shift of a multiple to be able to display half an hour is shown on the main dial 2 and Request some of the sub-dials 3 in a 1/48 offset relative to the 24 division 9 striking indices 29 as markings within the respective World location rings 17 and 18 for the existing half-hour zones, being next to letters in the indices 29 selected world locations from the Can represent half-hour zones. Otherwise, this is not the case Mandatory minute hand 23 in such a secondary time display 5 indispensable since this minute hand compared to that of the Main time display 4 is shifted by half an hour. For better A distinction is made in a non-working time display for half-hour zones Weltortezeiger 15 designed differently and the sub-dial 3 with a corresponding feature 26, about "1/2" marked. In Figure 1 is one of the secondary time displays 5 as an example of a half-hour zone shown.

The hour hands 19, 22 of all time displays 4, 5 rotate at normal movement of the clock in sync with each other, according to the selected world location show the hour of the respective time zone. The minute hand 20, 23 of all time displays also rotate synchronously with one another, whereby how mentions the minute hand 23 of a secondary time display 5 for half-hour zones is rotated by 180 ° relative to the minute hand 20 of the main time display 4 and the Minute hand 23 of a secondary time display 5 for all-hour zones on the basis of Matched with the minute hand 20 of the main time display 4 omitted can be. In addition, the day-night indicators 10 rotate synchronously together. The world place pointers 15 rotate when the clock is running normally not, but are via a mechanism explained later manually adjustable.

Through the analogous design of main dial 2 and sub-dials 3 it is easier to read the smaller sub-dials, the assignment a world location 6 to a sub-dial 3 by means of the world location pointer 15 and the World location rings 18 uniquely identify the displayed time zone and the day-night display 10 provides information about whether it is in the chosen world location morning, evening, day or night.

Before the other essential elements of a world clock according to the present invention will be discussed in more detail below first briefly the mode of operation and the nomenclature of the gear train of the mechanical module for analog display. To that extent The object of the invention primarily on the display and the controls of the world clock, this section only covers the elementary components of the gear train described.

Looking at Figure 4 you can see the essential parts of the Gear train of the minute display 100, the directions of rotation of the engaged stationary wheels are symbolized by arrows. A minute tube wheel 50 drives on the one hand, via minute intermediate wheels 51, one minute wheel 52 each Secondary time display 5 on which the minute hand 23 of the secondary time display 5 is firmly attached, and on the other hand is fixed with a not shown Minute tube connected, which the minute hand 20 of the main time display 4th wearing.

Figure 5 shows the gear train of the hour display 101 in more detail, whereby the minute tube 53 is in engagement with a change gear 54 and this over a change gear 55 an hour wheel 56 of the main time display 4, which the Hour hand 19 of the main time display 4 carries, drives. The hour wheel 56 of the Main time display 4 also drives via an intermediate idler gear 57 an hour wheel 58 of a secondary time display 5 with an hour hand 22 of the Secondary time display 5 carrying hour indicator wheel 59. This is in everyone Secondary time display 5 by means of a clutch of the hour display 109, which is off a star 63, a catch 64 and a spring 65, non-positively with the Hour wheel 58 of the secondary time display 5 connected. Also rotate at normal speed of the clock on each idle time display 5 Hour change wheel 60 and a corrector change wheel 66 synchronously with one another, which with the hour indicator wheel 59 or the hour wheel 58 of the Secondary time display 5 are engaged, as well as a correction wheel 67, which with the corrector gear 66 is engaged freely with. The latter is possible because As can be seen in Figure 5c, the correction wheel 67 each with a first Pawl wheel 70 cooperates, in each case with the first ratchet wheel 70 by a spring 69 laterally against this pawl 68 this first ratchet wheel 70 can slide. These first ratchet wheels 70 occur are only in action when there is a correction to be explained later in the normal course of the world clock 1 silent. For this purpose, the correction wheel 67 shows how will be explained in more detail in the description of Figures 10c and 11b, a double clutch 108, which two opposite movements, namely the normal running of the clock and the movement of the Correction, recording and forwarding is able. The two clutches work on the well-known ratchet sawtooth principle and are mounted in opposite directions to move in one or the other depending on the origin forward the other direction.

The day-night display 10 of each off-time display 5 is fixed connected to a day-night display wheel 62 and this is, as in the Figure 6 depicting the gear train of the day-night display 102, each via an hour change gear 61, which with the hour change wheel 60 is connected in synchronism with the hour indicator wheel 59 of the concerned Secondary time display 5 driven.

The date indicator 7 is driven in a known manner via an in Figure 7 shows the gear train of the date display 103. The Minute tube 53 drives a date change wheel 93, which with the Date change gear 94 is connected, which in turn with the date switching wheel 95 is engaged. This makes one revolution in 24 hours and moves thus once a day by means of the shift finger 96 attached to it and the Teeth on the inside of the date indicator 7 the latter by a 1/31 turn around its axis.

A world clock 1 according to the present invention also has one A series of controls and settings on the Figures 2a-c and 3a-b will now be explained in more detail.

One protruding from the outside of the housing 14
The main adjusting device in the form of a crown 11 has three snap-in positions. A non-drawn rest position 11a serves to pull up the base work, as is symbolically represented by arrows in FIG. 2a. A first drawn position 11b serves to correct the hour display and the date display of the main time display 4 by means of hour increments in both directions of rotation, shown in FIG. 2b. The hour hand 19 of the main time display 4 completes one revolution in twelve steps independently of the minute hand 20 and therefore enables a quick and convenient hour setting, such as when changing from summer to winter time or possibly when changing the time zone. By moving the hour hand 19 of the main time display 4 forward and backward around the 12 o'clock position, the date display 7 always switches one step forward in this position of the crown 11, which ensures a quick date setting. A second drawn position 11c is used to set the main time display to the second, the rotation of the crown 11 in this position, also in both directions of rotation, causing the hour and minute hands of all time displays 4, 5 to move synchronously, as shown in FIG. 2c.

The world clock also points to each of the additional analog ones Time displays 5 a secondary setting device in the form of a trigger 12, the also laterally on the housing 14 of the world clock 1 and the associated Secondary time display 5 is attached opposite or adjacent. Such pushers with a corresponding push mechanism 104 are approximately known from chronographs and make moving parts with their own compression spring represents, in the pressed position 12b automatically back to the starting position 12a snap back. As can be seen in FIG. 10, each push button is closed Security a pressure point mechanism consisting of a spring 48 and one associated rocker 47 is built in, which is a minimum pressure for the Execution of the pusher function required, so that by accidental bumping, for example when wearing or taking off the watch, not the time or the world location of one Secondary time display 5 is adjusted. These push buttons have two functions. To the they allow one, insofar as the minute display of the secondary time displays 5 such described above via the crown 11 is regulated by the main time display 4, the setting of the hour hands 22 of the secondary time displays 5 independently both among themselves and from the minute hands 23 of the non-productive time displays 5 and all hands 19, 20, 21 of the main time display 4, whereby, as in Figure 3b shows the hour hand 22 and the day-night display 10 at each time you press the corresponding time display 5 Move pusher 12 synchronously by one hour. As shown in Figure 3a, on the other hand, after a change of the described below Pusher function, by pressing a pusher 12 to advance the associated world location pointer 15 by a 1/24 turn, in which Case of the world place pointer 15, the hour hand 22 and the day-night display 10 a secondary time display 5 move simultaneously, whereas this action on all other display elements has no influence. This allows the analog Main time display 4 also shows the world location and the associated time in the auxiliary time displays 5 easily, quickly and safely.

This double functionality of the pushers 12 is ensured in the case described here by way of example by the elements of a world clock according to the invention shown in FIGS. 10 and 11. When a push button 12 is actuated, the hour hand 22 of the corresponding secondary time display 5 is set on the one hand via a push slide 43 which can be displaced with the push button 12, the end of which cooperates with one extremity of the rocker 47 in such a way that a connecting piece 74 which is rotatably mounted on the other extremity thereof moves that this in turn rotates a coaxial to the first ratchet 70 ring 72 by a certain angle β ₁ about its axis. This is symbolically sketched using arrows in Figure 10b, where the first position of the parts was also marked with dash-dotted lines and the second position with solid lines, and the less important part of the gear train of the hour display 101 was only indicated with dotted lines for better understanding , and shown in detail in FIG. 10c with the correction mechanism 107. Insofar as the ring 72 is equipped with ring pawls 73, which can hook into a second ratchet wheel 71, the latter also performs a corresponding rotation as the ring 72. The first ratchet wheel 70, which is fixedly mounted on the second ratchet wheel 71, engages by means of its toothing in the pawls 68 pressed laterally with the aid of the springs 69 mentioned, so that the correction wheel 67, on which the pawls 68 are movably mounted, also rotates. As can be seen in Figure 10a, the correction wheel 67 moves the correction wheel 66 and the hour change wheel 60, which in turn is in engagement with the hour indicator wheel 59. As mentioned in the explanation of FIG. 5, each hour wheel 58 of a secondary time display 5 is non-positively connected to the hour indicator wheel 59 carrying the hour hand 22 of the secondary time display 5 by means of a coupling of the hour display 109. By overcoming the force exerted by the spring 65 on the detent 64 of this clutch 109, the engagement of this detent 64 in the subsequent notch of the associated star, which has twelve or twenty-four teeth, and thus a mutual rotation between the hour wheel 58 of a secondary time display 5 and the associated hour indicator wheel 59 by the angle β ₂ , which corresponds to an hourly step. Each time the button 12 of a secondary time display 5 is actuated, the associated hour hand 22 is advanced by one hour. When the trigger 12 is released, its rocker 47 and the trigger slide 43 snap back into the starting position by the action of the pressure point spring 48, rocker spring 75 and slide spring 99.

After changing the handle function as described below can on the other hand via the pushers 12, as in Figures 11 a and 11b by means of a schematic representation of the movement sequence as well Detailed sectional and top views of the double clutch 108 of the Correction wheel 67 illustrated, the world location pointer 15 of a secondary time display 5 can be set. This setting takes place according to the same procedure as in described above, but with the difference that not only the correction wheel 67 by the pawls 68 movably attached to it, but in each case also one arranged concentrically to the correction wheel 67 Friction wheel 76 is rotated with the aid of a friction spring 77. This friction wheel causes 5 at each idle time display via a first world location idler 78 and second world location intermediate wheel 79, which with a world location indicator wheel 80 in Engagement is a rotation of the world location pointer 15. This world location indicator wheel 80 is analogous to the coupling of the hour display 109 shown above, known star-detent coupling 110 equipped, which a detent 82, a Spring 83 and a star 81 with twenty-four teeth and therefore the Setting the world location pointer 15 in 1/24 offsets for one revolution allowed. While in the first function mode of a push button 12, only the Hour hand 22 and the day-night indicator 10 of the corresponding Secondary time display 5 are moved, the rotates in the second mode associated world place pointer 15.

As can be seen, for example, from Figure 1, a world time clock according to the present invention furthermore has a special operating unit in the form of a rocker 13 for selecting the above-mentioned function of the pushers 12 for the secondary time displays 5. This rocker 13 can be implemented, for example, as a snap-in pushbutton with two positions 13a and 13b, the part of the rocker projecting from the housing 14 indicating the function setting of the pushers 12. According to FIG. 3a, the rocker 13 is to be pressed down for the setting of the world location pointer 15 of a secondary time display 5 and, as in FIG. 3b, to be pushed up for the setting of the hour hand 22 of a secondary time display 5. For this purpose, two symbols corresponding to these functions can optionally be applied near the two ends of the rocker 13 on the housing 14 or directly on the rocker 13. A preferred embodiment of such a rocker 13 is shown schematically in Figures 8a-e. In two cavities on the inside of the two ends of the rocker 13 there are a contact pin 131 which can be pivoted about its outward-pointing extremity and a locking pin attached to the housing 14, for example in the form of a pin there
screwed, so-called locking screw 132, housed, and the rocker 13 is in a shallow indentation on the side of the housing 14 of the world clock 1 also pivotable about an axis located approximately in the middle of the rocker 13, for example in the form of an articulated screw 133. The locking screw 132, which can be adjusted by turning, for example by means of a screwdriver, for fine adjustment of the position of the rocker 13, is accommodated as an element with a part of double conical shape in a corresponding bore in the housing 14 in such a way that the switching movement of the rocker 13 in its two positions 13a and 13b is guided by means of springs 134 and a plate 135. Here, the molded body or head of the locking screw is designed such that two switching positions of the rocker 13 are defined in cooperation with the spring 134, so that the rocker 13 is bistable. When the rocker 13 is pressed, as indicated in Figure 8e, the two ends of the spring 134 attached to the rocker 13 slide over the double-conical head of the locking screw 132, so that a clear click can be heard, which shows the wearer the switching of the rocker acoustically confirmed. According to Figure 8a, the contact pin has a radial longitudinal bore 136, in which a further spring 134 attached to the rocker 13 is suspended, and by means of which the stroke of the contact pin 131 can be adjusted by varying the bore length. This contact pin 131 ensures the transmission of force from the rocker 13 into the interior of the housing and, due to an associated bore penetrating the housing 14, in which the contact pin 131 is guided by means of a sealing sleeve 137 provided in this bore and a sealing ring or O-ring 138 will cooperate with the parts located inside the housing, thereby simultaneously achieving watertightness with respect to the inside of the housing. This cooperation, which allows the aforementioned change of the trigger function, involves next to one
Rocker mechanism 105 also has a specific locking mechanism 106 and can be understood from Figure 11a. The rocker 13 presses the contact pin 131 somewhat inwards through the corresponding bore when set to its first, pressed-up position 13a, as a result of which a rocker slide 84 arranged at the end of this rocker transfers this movement to a rocker rake 85 attached to the other end of this rocker slide, which in turn is pivotally attached to its extremity. Its rake arm is in engagement with an arm of a likewise pivotable rake wheel 86, so that the rotary movement transmitted by the rocker rake 85 is transmitted via a second arm of the rake wheel 86 to a first rake intermediate wheel 87 and from there to a second rake intermediate wheel 88. The latter is in engagement with a cam wheel 89, which carries a cam 90, which exerts a force on the blocking lever 91 for each secondary time display 5 due to the experienced rotary movement. This force exceeds the force exerted on it by a return spring 92 of the blocking lever 91, so that this blocking lever 91 is pressed laterally onto the associated world location indicator wheel 80 and thus its rotation is prevented. This means that it is not possible to set the world location pointers 15 of the secondary time indicators 5 in the upward position 13a of the rocker 13, while in the second, downward position 13b of the rocker 13 the return spring 92 releases the blocking lever 91 from the world location display wheel 80 and thus also the World location pointer 15 can be set.

This blocking mechanism 106 is also shown in Figures 12a-b to operate by pulling the crown 11. If the crown and thus the Elevator shaft slide 41 and the elevator shaft 42 is pulled, so one by one about its center axis pivotable angle lever 33 moves. This in turn acts on a control rocker 32, which one with the Cam wheel 89 meshing rake 97 by a certain amount Angle rotates, whereby a second cam 98 each Blocking lever 91 of a secondary time display 5 on the corresponding World location indicator wheel 80 presses. This is drawn in the first and second Position of the crown 11 an adjustment of the world place pointer 15 excluded, while the world location indicator wheels 80 and thus the world location pointers 15 are on the ground the action of the return springs 92 on the blocking lever 91 in the Rest position 11 a of the crown 11 are movable.

Finally, the world clock 1 has one of its essentials Components shown in Figure 9 control mechanism 30 that the Function of the movable controls crown 11, pushers 12 and rocker 13 by blocking or releasing it in a manner that is transparent to the user Controls one another that both damage the watch and a accidental adjustment of one of the time displays 4,5 by simultaneous Operation of the crown 11 and the pusher 12 is excluded. In the Figures 2a-c is the effect of this control mechanism using arrows represented symbolically. The crown 11 is in its rest position 11 a When you wind the watch, the three pushers 12 are just like the rocker 13 usable and thus the hour hand 22 and the world place hand 15 of the Secondary time displays 5 adjustable. However, the crown 11 is in one of its drawn positions 11 b or 11 c, as in Figures 2b and 2c symbolically marked by crossed out arrows, the pushers 12 no longer closed operate so that an adjustment of an element of the additional time displays 5 is excluded and only that corresponding to the position of the crown 11 Setting can be carried out, i.e. the setting in hourly steps Hour and date of the main time display 4 in the first drawn position 11 b of the crown 11 and the simultaneous setting of both the hour 19 and the minute hand 20, the main time display 4 and the hour and Minute hands 22 and 23 of the secondary time displays 5 in the second drawn Position 11 c. The rocker 13 remains in the drawn positions 11b and 11c Krone 11 can still be used, but this has no effect. On the other hand, pressing at least one pusher 12 when the Crown 11 is in its rest position 11 a, the crown 11 blocked, so that the Do not allow the crown to be pulled simultaneously while operating a push button 12 and thus the setting functions of pushers 12 and crown 11 are also in this Do not let the constellation run simultaneously. The remains on while pressing Rocker 13 again without effect in its two positions 13a and 13b switchable. By releasing the depressed button 12 or resetting the Crown 11 in the rest position 11 a, the respective blocking again canceled.

This control of the controls is carried out by the in Figure 9 mechanism explained. Main component of this Control mechanism 30 in the exemplary embodiment presented is a concentric around the center 27 of the world clock 1 Control ring 31, which has a rocker and a lever advantageously identical to the mentioned control rocker 32 and the Angle levers 33, with the elevator shaft slide 41 and the elevator shaft 42, So cooperates with the crown 11, and on the outside the pushers 12 has opposite, lateral incisions 34. Depending on the snap-in position Crown 11 takes ring 31 with its incisions 34, as in Figure 9 represented symbolically with an arrow by the action of the angle lever 33 at least two different radial positions 31a and 31b, the first Position 31 a of the rest position 11 a and the second position 31 b the drawn Positions 11 b or 11 c corresponds to crown 11. In addition, the pushers point 12 each capable of assuming two positions 43a and 43b Pusher slide 43 with a pin 44 fastened thereon, which at Operation of the pusher 12 in the opposite incision 34 of the ring 31 can be pushed if the crown 11 is in its rest position 11 a and thus the incisions 34 are opposite the pins 44. In the drawn positions 11 b and 11 c of the crown 11, this is not the case, so that the Lever 12 by pushing the pins 44 against the outer edge of the ring 31 blocked when trying to push. However, is a pusher 12 in Rest position 11 a of the crown 11 pressed, so the associated pin 44 in the opposite incision 34 and the ring 31 can, like one Detailed view of Figure 9, indicated by a jagged arrow, not are rotated, thus causing the crown 11 to pull out blocked. This makes it an uncomplicated and effective control of the Controls crown 11 and pusher 12 guaranteed with each other.

Without reason in the individual sections of the description the large number of components was specifically mentioned, the individual mechanical parts and their specific arrangement not on the described Embodiments limited, but can be functionally identical are replaced without affecting the scope of the present invention disclosed inventive ideas. The described embodiment of a world clock according to the present invention is therefore not to be interpreted as limiting in any way.

Among other things, the detailed design of the operating unit 13 to choose the two functions of the pushers 12 different, in the frame of the inventive idea are subject to changes such as the replacement of the rocker 13 by one or two adjacent Pushbuttons, which also change over when you press them Confirm function of push buttons 12 visually and / or acoustically.

In particular, as a further embodiment, a world time clock can also be implemented, in which no world location 6 corresponding to the displayed time zone is assigned to the time indicated in a secondary time display 5, so that the double functionality of the secondary setting devices 12 and thus the operating unit 13 for selecting their function is omitted. The
Regardless of this, control mechanism 30 for controlling the functions of the main setting device 11 and the secondary setting devices 12 with one another continues to be a simple and effective means of improving the operating functions and is therefore an important component of such a watch.

Similarly, it is also possible to use the above in a world clock described display of a corresponding world location 6 for in the Secondary time displays 5 times the control mechanism 30, approximately to reduce production costs. The still existing Operating unit 13 of such a clock ensures the selection of the function of auxiliary adjusters 12, regardless of control thereof Actuation depending on the actuation of the main setting device 11.

The embodiments of a described above World clock according to the present invention roughly illuminate the frame of the loud the inventive thought possible changes and variations that can experience a world clock according to the invention, due to the multitude of However, as mentioned, components are not subject to changes in the individual parts received without this being interpreted as limiting.

The main elements of the so far introduced using the example of a world clock present invention, namely a control mechanism for coordination the functions and the actuation of the main and secondary adjustment device (s) a clock and an operating unit for selecting the function of a A clock setting device can of course also be used in a clock another type, but with the same necessities and the same Requirements for such components as the world clock presented, be used. They are therefore isolated with regard to their respective Properties to look at. In general, these two according to the invention Components in any watch with at least one auxiliary setting device and with a main setting device, which has at least two locking positions, namely a rest position and at least one pulled position, to be used.

For example, it is possible to use the control mechanism mentioned in a chronograph that is usually analog or digital, as in the case of the world clock. In such a case, the chronograph usually has either a chronograph display integrated in its main time display or in a separate secondary time display, which is usually equipped with one or two additional chronograph or stop hands for time measurement. Such a chronograph therefore usually also has one
Main setting device with at least two snap-in positions for setting the main time display and at least one secondary setting device assigned to the chronograph display or its hands. The coordination of their functions, which are of course different from those of the setting devices of a world clock, can, however, be implemented according to the same principle and with exactly the same means described above, that is to say by means of the control mechanism mentioned.

The same applies to the control unit for selecting the function of a Setting device of a watch, be it in the form of a rocker, a push button or the like, to be transferred to any watch, which setting devices with at least two assigned different functions, can be used.

The scope of the inventive concept of the present invention therefore encompasses both the two core elements of the invention, the
Control mechanism for coordinating the functions and the actuation of the main and secondary setting device (s) of a watch and the operating unit for selecting the function of a setting device of a watch, as such as well as the combination of these devices with corresponding watches of various types suitable for integrating these components.
