  • Some watches include a box designed to be able to separate the bezel from the middle on which it is fixed without tools, that is to say comprising a bezel fixed to the middle in a removable manner.
  • This type of bezel makes it possible to personalize the watch case, for example by replacing one bezel with another including different decorations, or makes maintenance operations easier.
  • a watch case comprising a middle part, a bezel and a connecting ring arranged in a movable manner in rotation relative to the middle part and by means of which the bezel is able to to be fixed to the middle in a position in which said bezel is forced to bear against said ring by an elastic return force generated by an elastic member.
  • the connecting ring and the bezel each comprise at least one interlocking member cooperating together when the bezel is fixed to the middle part, in order to eliminate any relative mobility between said connecting ring and said bezel.
  • the connecting ring and the bezel are configured so that when the bezel is acted upon by a force going against the elastic return force, the interlocking members no longer cooperate with each other, so to release the rotational mobility between said connecting ring and said bezel.
  • the connecting ring and the bezel are further configured so as to be able to be separated when they are arranged in a predefined angular position relative to each other.
  • the invention may also include one or more of the following characteristics, taken individually or in all technically possible combinations.
  • the connecting ring comprises a peripheral shoulder by which it is arranged in abutment against an axial surface of the middle formed by a radial lip.
  • the interlocking members of the bezel and the connecting ring respectively comprise a coupling element, said coupling elements having complementary shapes and cooperating with one another when the bezel is fixed to the middle and being separated from one on the other when the bezel is subjected to a force going against the elastic return force.
  • the coupling elements are configured, when the bezel is subjected to a force going against the elastic restoring force, to prevent the rotation of the bezel relative to the connecting ring in a first direction of rotation and to authorize its rotation in a second direction of rotation opposite to the first direction of rotation.
  • the connecting ring comprises teeth cooperating with an elastic indexing element fixed to the middle part.
  • the teeth are shaped so as to allow rotation of the connecting ring only in the first direction of rotation.
  • the interlocking members of the bezel and the connecting ring respectively comprise a translation stop element, said translation stop elements cooperating with one another when the bezel is fixed to the middle part and being released from each other when the coupling elements are separated from each other and the bezel and the connecting ring are arranged according to the predefined angular position.
  • the translation stop elements of the bezel and the connecting ring are formed respectively by a radial tongue, the tongues extending in opposite directions and each comprising an interface face by which they rest against each other when the bezel is attached to the caseband.
  • the coupling element of the connecting ring is formed by a housing defined between two radial stops, one of which is formed by a lateral end of the element stopping in translation of the connecting ring, called the “stop end”, the coupling element of the bezel being formed by a radial tab intended to be engaged in said housing.

  • first direction of rotation By way of Consequently, the bezel 12 is capable of pivoting in a single direction of rotation relative to the middle part 11.
  • the connecting ring 13 and the bezel 12, and in particular their respective interlocking members are configured so that when the bezel 12 is stressed by a force going against the elastic return force, the members nesting no longer cooperate with each other and thus make it possible to release the rotational mobility of the bezel 12 relative to said connecting ring 13. It should be noted that when the bezel 12 is stressed by a force going against the elastic restoring force, it is moved axially according to a stroke only necessary to allow the release of the interlocking members, as described in more detail below; this axial movement being not or barely perceptible by the user.

  • the interlocking members of the bezel 12 and the connecting ring 13 are visible in the exploded views of the figures 5 And 6 and respectively comprise a coupling element. According to its definition accepted in the field of mechanics, a coupling allows the transmission of a rotational movement between two parts. Coupling elements therefore allow, when the interlocking members cooperate with each other, to secure in rotation the bezel 12 and the connecting ring 13.
  • the coupling element of the connecting ring 13 is formed, in the preferred embodiment, by a housing 135 defined between two radial stops.
  • the radial stops extend outwards.
  • the coupling element of the bezel 12 is formed by a radial tab 122, visible on the Figure 6 , of a shape complementary to that of the housing 135 and engaged in said housing 135 when the interlocking members of the bezel 12 and the connecting ring 13 cooperate together.
  • this radial tab 122 extends from a skirt 120 of the bezel 12.
  • the coupling elements are advantageously configured to prevent the rotation of the bezel 12 relative to the connecting ring 13 in the first direction of rotation, when the bezel 12 is subjected to a force going against the force elastic return.
  • the first direction of rotation of the bezel 12 corresponds to its unique direction of rotation relative to the middle part 11 when it is fixed to the latter. Thus, the risk of accidentally separating the bezel 12 from the middle part 11 during its rotation is excluded.
  • first radial stop 136 extends axially over a distance such that it constitutes a stop for the radial tab 122 whatever the axial position of the bezel. 12, that is to say whether or not it is subjected to a force opposite to the elastic return force.
  • the interlocking members of the bezel 12 and the connecting ring 13 respectively comprise, in addition, a translation stopping element, as visible on the figure 2 , 3 , 5 And 6 .
  • the translation stop elements cooperate with each other when the bezel 12 is fixed to the middle part 11 and are released from each other when the coupling elements are separated and that the bezel 12 and the connecting ring 13 are arranged according to the predefined angular position relative to each other.

  • the bezel 12 and the connecting ring 13 can each comprise several interlocking members, for example three, as shown in the figures. It is also possible, to constitute the second radial stop 137, to replace the inclined portion 1381 with a similar projecting portion, for example formed by a pin, an extra thickness of appropriate shape, etc. It is also possible for the interface face 1380 to form a single inclined section to constitute the second radial stop 137, the straight section of the tongue 138 then increasing towards the housing 135. It is also possible to provide an axial offset of the radial tab 122 per relative to the tongue 123 of the bezel 12, so that when said tongue 123 bears on the tongue 138 of the connecting ring 13, the radial tab 122 is housed in the housing 125. This last example makes it possible to conform the tongue 138 to the connecting ring 13 in any shape.
