A dewar device (1) for mechanical and/or functional components (2) of a watch (3), the device (1) being provided with a bracelet and a casing (4) including an enclosure (5) wherein it is possible to arrange a case (6) of the watch (3) and at least one reversible connecting element (7) fixing the watch (3) case (6) in the enclosure (5) of the casing (4) while keeping it remote from all the elements (10a, 10b, 10c) of the casing (4) defining this enclosure (5), the at least one reversible connecting element (7) being provided with a body forming a structure (8) including at least one recessed area (9).

Method of assembling a timepiece comprising a watch movement and a water-resistant case, the method comprising a first stage of closing the case by fitting and securing a first case element, more particularly a back, and then a second stage of closing the case by actuation of a second case element, more particularly a stem, in particular a winding stem or a valve stem or a push-button stem, the second case element being mobile between a first configuration, in which a fluid communication between the interior of the case and an environment outside the case is permitted, and a second configuration, in which the fluid communication between the interior of the case and the environment outside the case is limited, the second stage of closing being an actuation of the passage of the second element from the first configuration to the second configuration.

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.

An example case includes a case main body having a first insertion hole; a first exterior case having a second insertion hole coaxially corresponding to the first insertion hole and arranged on an upper part of the case main body; and a fastening member having a fixing portion to be fixed in the first insertion hole and a fitting portion to be fitted into the second insertion hole, the fitting portion being fitted into the second insertion hole while deforming a portion of the fitting portion to be fitted into the second insertion hole, wherein the fixing portion of the fastening member fixed in the first insertion hole includes a press fitting portion press-fitted into the first insertion hole, and wherein the press fitting portion of the fastening member includes a biting portion which bites into an inner circumferential surface of the first insertion hole of the case main body.

A watch case includes a capsule receiving a watch mechanism, arranged along a main axis, and which includes a front side that has the watch face. The watch case further includes a middle surrounding the capsule and provided with an essentially cylindrical housing open toward the back from which side it receives the capsule. The watch case further includes a bezel placed against the back of the capsule. The bezel includes tabs arranged on the outer contour of the capsule, which are in a blocking position partly inserted in the interior of at least one groove having a circular orientation, produced in the cylindrical part of the housing of the middle.
