Abstract

The invention relates to a control system for a rotating member of a timepiece, including a control member for actuating said rotating member, and a transmission device between said control member and said rotating member. The control system is characterised in that the gear device is a hybrid gear device including a first element which can move about a first axis of rotation (10) and is provided with a drive roller (25) made of an elastomer material, and a second element (31) which can move about a second axis of rotation (30) and is provided with a toothed gearing (32). The drive roller (25) engages with the toothed gearing (32) by means of friction.

Abstract

The invention relates to a portable object (1). This portable object comprises at least one decorative transparent or semi-transparent item (2) positioned and held on a support (6). This item has the shape and appearance of a precious stone. The portable object also includes a layer of luminescent material (10) located at least between one part of the support (6) and the decorative item (2), the latter being held over the support to produce a visual effect through the item by reflection and refraction of the light passing through it.

Abstract

The invention relates to a watch band (1) that comprises a first strap (2) and a second strap (3). The second strap (3) is connected to a clasp (1a) consisting of a hooking device (13). The hooking device (13) enables the two straps (2, 3) to be rigidly connected to each other.  The invention is characterized in that said clasp (1a) moreover includes a safety device (17) that enables an improved rigid connection by clamping the first strap (2) onto the clasp (1a).

Abstract

The invention relates to a control device for a timepiece comprising a case middle defining an inner space in which a movement is located, which device comprises a bezel rotatably mounted on the case middle and a transmission component comprising: a rod rotatably mounted in a hole extending through the case middle, a first cam located within the inner space and rigidly rotationally attached to one end of the rod, and engaging a control lever mounted on the movement when the transmission component rotates, and a second cam located outside the space, and rigidly rotationally connected to the other end of the stem, and comprising at least one bearing surface. The bezel further comprises a contact surface engageable with the bearing surface when the bezel rotates, thereby rotating the transmission component. The control device also comprises a return spring acting on the bezel.

Abstract

A timepiece comprises a fixed external case (1) in which a tiltable internal case (10) is articulateable by a spring action to an inclined position. A locking/unlocking mechanism is characterised in that it consists of a movable covering element handled on the plane of a timepiece part such as the rotational bezel (20) of the internal case (10) provided with a toe (22) engageable into the slot (2) of the external case (1).
