The system (10) for fixing a timepiece movement (2) to a watch case (30) element (3) includes at least one clamp (1), in particular at least two clamps, preferably three clamps or four clamps, which is intended to come into contact firstly with the movement and secondly with the watch case element, and a device (2a′; 3a′) for modifying the stiffness of the at least one clamp, particularly for modifying the bending stiffness of the at least one clamp, when the movement is fixed and/or displaced relative to the watch case element.

A case including a case main body, a first exterior case which is arranged around an outer circumferential portion of the case main body, and a second exterior case which includes an impact receiving portion that is opposed to an inner circumferential portion of at least one of an upper part and a lower part of the first exterior case, and is attached to at least one of the upper part and the lower part of the first exterior case.

A wrist watch or the like having a case comprising at least an internal housing having at least a front opening. A dial is inserted in the housing, arranged in the proximity of the front opening and facing outwards. A horology mechanism is housed in the housing and is operatively connected to the dial, the horology mechanism having at least one support linked together with the case and having at least a seat able to house the mechanism.

A watch or the like having a support member comprising an internal housing seat having a rear opening. A horology mechanism is housed inside the housing seat and has a rear portion arranged facing towards the rear opening. A bottom element is associated in a removable manner with the support member for closing the rear opening. The bottom element has a portion made of a yielding material, facing inside the housing seat and associated with at least part of the rear portion of the mechanism.

A case by which impact resistance is enhanced and damages due to impacts are prevented, a timepiece equipped with the case, and a fastening member are provided. The case includes a case main body which has first insertion holes, a first exterior case which has second insertion holes coaxially corresponding to the first insertion holes and is arranged on the upper part of the case main body, and fastening members which have fixing portions to be fixed in the first insertion holes and fitting portions to be fitted into the second insertion holes. Each fitting portion is fitted into the corresponding second insertion hole while being deformed. Therefore, even if the wristwatch case is subjected to an external impact, the first exterior case does not rattle in the direction perpendicular to the axial direction of the fastening members, whereby the case main body is prevented from being damaged.

The present invention concerns a shock absorber device for an arbor of a timepiece element including a support comprising a base cup surmounted by a peripheral rim delimited, opposite said cup, by an upper surface and including an outer wall, said cup and the rim defining together a housing, the device further including at least one pivot module extending along an axis, said at least one pivot module being arranged inside said housing and able to cooperate with said arbor, said device comprising fastening means including a peripheral shoulder extending from the rim towards the axial centre of the cup, elastic means being arranged between the pivot module and the shoulder to exert a stress on the pivot module.

The system (10) for fixing a timepiece movement (2) to a watch case (30) element (3) comprises at least one clamp (1), in particular at least two clamps, preferably three clamps or four clamps, which is intended to come into contact firstly with the movement and secondly with the watch case element, the at least one clamp being made of a superelastic alloy and/or of a shape memory alloy, particularly of a nickel-titanium alloy such as Nitinol.

A shock-absorber device for a wheel arbor of a micromechanical device includes a support which includes a turning-arbor delimited by a rim defining a housing into which a pivot module is inserted. The pivot module includes a setting having a central orifice into which is inserted a bored stone. An endstone is placed on top of the bored stone. The shock-absorber device also includes a spring ring arranged between the support and the pivot module. The shock-absorber device is equipped with a bayonet system for mounting the spring ring. The bayonet system includes a peripheral shoulder under which is formed a circular groove which defines a holding area. The spring ring is equipped on an outer periphery with at least one catch. At least one first notch which leads to the circular groove is provided in the peripheral shoulder.

A resilient casing ring (200) for casing a horological movement (10) inside a watch case (100) including a middle (110). The casing ring (200) includes an annular body (205) with a central axis (Z), and fastening tabs (210) carried by the annular body (205) and cooperating with the middle (110) to form a bayonet casing system (300) by rotation of the resilient casing ring (200) relative to the middle (110) about the central axis (Z), between an insertion position and a locked position. The casing ring (200) includes resilient retaining element cooperating with the horological movement (10) and exerting an axial force parallel to the central axis (Z) on the horological movement (10) by elastic deformation of the resilient retaining element when the resilient casing ring (200) is in the locked position in the middle (110).

The system (10) for fixing a timepiece movement (2) to a watch case (30) element (3) includes at least one clamp (1), in particular at least two clamps, preferably three clamps or four clamps, which is intended to come into contact firstly with the movement and secondly with the watch case element, and a device (2a; 3a) for modifying the stiffness of the at least one clamp, particularly for modifying the bending stiffness of the at least one clamp, when the movement is fixed and/or displaced relative to the watch case element.
