Abstract: Gong mounting device designed to bear against a crystal (10) closing a striking-watch case. This device comprises a block (20) for immobilizing at least one end (1, 2) of a gong (T1, T2) inside the watch case, and a means (30) for mounting this block (20) on said crystal (10). The mounting means (30) is a clamping-type mounting means enabling the block (20) to exert pressure on the crystal (10).

Abstract: A battery housing comprises a hole entirely piercing the watch base plate and a cover closing the hole. Such cover is secured to the hole by fastening means which comprises in one form a flange projecting into the hole. In the cover moreover a tongue is raised which serves as a mechanical support to one face of the battery and, via a printed circuit arranged between the cover and the battery, the electrical contacting of the battery electrode forming part of said face.

Abstract: A hand setting mechanism including a stem and a sliding pinion slaved to one another by means of a setting lever and a yoke. The sliding pinion is driven in rotation by means of a slit with which it is provided and which cooperates with two flattened surface borne on the stem. The sliding pinion is freely engaged in an orifice pierced in the base plate and is provided with a circular hole which serves as a bearing for a pivot at the end of the stem.

Abstract: The module comprises a first printed circuit (1) on one end portion (51) of a flexible support (50), and a second printed circuit (40) housed in a recess (53) provided in the watch plate (22). The first circuit has four conductive areas (2, 3, 8, 9). The second circuit has one side (40b) a first pair of conductive areas (41, 42) and on its other side (40a) a second pair of conductive areas (47,48). Two of the conductive areas (2, 3) of the first circuit are connected to the electrodes of a cell while its two other conductive areas (8, 9) are connected to the supply terminals of an electronic circuit. The second circuit (40) may be placed in the recess (53) in two different positions, identified by a pair of symbols. Each position corresponds to a different cell polarity.
