Abstract

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.

Claims19

Dependent claims

A system for fixing a timepiece movement to a watch case element, the system comprising:

at least one clamp, which is configured to bend due to coming into contact with a surface of the movement and with a surface of the watch case element a) when the movement is pressed under action of the screw during assembly and/or b) when the movement and the watch case element are relatively displaced in an axial direction of the movement such as to press the at least one clamp between said surface of the movement and said surface of the watch case,
a fixing element that fixes a position of the clamp relative to the movement or to the watch case, and
a device for modifying the bending stiffness of the at least one clamp, when the movement is pressed under action of a screw during assembly and/or displaced in an axial direction relative to the watch case element,
wherein the device for modifying the stiffness of the at least one clamp is arranged so that the bent length of the at least one clamp is modified when the movement is fixed to the watch case element or displaced relative to the watch case element from a rest position in which a first surface of the movement abuts against a second surface of the case element,
wherein the device for modifying the stiffness of the at least one clamp is arranged so that the bent length of the at least one clamp is modified so that the bent length of the at least one clamp is reduced when the movement is fixed to the watch case element or displaced relative to the watch case element from the rest position in which the first surface of the movement abuts against the second surface of the case element,
wherein the device for modifying the stiffness of the at least one clamp is arranged so that the bent length of the at least one clamp is modified so that the bent length of the at least one clamp is reduced in response to the movement being fixed to the watch case element or displaced relative to the watch case element from the rest position in which the first surface of the movement abuts against the second surface of the case element.
