Abstract: There is disclosed a device (1, 34) for positioning a first element (24) with respect to at least a second element (25) by means of a resilient locking member made in a single piece and having two ends (2, 3) connected by a bar (4) capable of being resiliently deformed in its axial direction (5). The longitudinal resilience of the bar (4) is due to the fact that it includes a plurality of apertures (11) over its length, said apertures (11) being located alternately on either side of a median plane (14) of the bar (4). This locking member can easily be manufactured in the form of a moulded plastic part.

Abstract: There is disclosed a wristwatch (1) whose wristband (6) is attached to a support (3) with respect to which the case (2) can turn over to show one or other of its faces (16, 17). The support (3) includes, on the parallel inner surfaces (9) of its flanges (7), grooves (10) in which snugs (39) connected to the case can slide and pivot. Stops are provided in the grooves (10), to stop the case sliding after a first sliding travel of the snugs (39) from the ends (42) of the grooves, to define a pivoting zone of the case, before the snugs effect a second sliding travel to the other ends (42). Support surfaces (11) and a transverse recess (12) are provided on the bottom (4) of the support to prevent the case turning over except in the zone of the stops.

Abstract: A wristwatch (1) whose wristband (6) is attached to a support (3) with respect to which the case (2) can be reversed in the longitudinal direction to show one or other of its faces (16, 17). The case has a pointed profile at its ends, its faces (16, 17) having convex profiles, which are preferably similar. The bottom (4) of the support (3) is concave so as to have a substantially complementary profile to those of the faces of the case. Further, the lateral flanges (7) of the support have substantially the same convex profile, so that the case and the support are substantially flush with each other over the entire length of the case, thus giving a fluid attractive appearance to the watch and to the reversing movement of the case.

Abstract: Bar (6) for attaching a watch wristlet (4) intended to be engaged by sliding into a passage (12, 14) of a watch case (2) and inserted in one of the ends of a wristlet (4), the bar (6) including an elongated body (22) and including a locking device, the locking device including a lock (28) subject to the action of a resilient element (30) and a control (32, 36) for controlling the lock (28) which is accessible from one end of the bar (6), the lock being arranged so as to project in a transverse direction with respect to the body (22) outside the body of the bar (6), in a first position (FIG. 1) in which the control (32, 36) is not actuated, and to retract inside the body (22), in a second position (FIG. 2) when the control (32, 36) is actuated.

Abstract: A rotating bezel (18) is hooked on a fixed ring (17) intended to be fixed to the frame of the casing. This bezel (18) comprises a toothed rack (21) in which is engaged the free end (22b) of a positioning spring-wire (22) whose other end (22a) is elbowed and engaged in a hole (23) of the fixed ring (17). This spring-wire (22) comprises three segments, two end segments (22c, 22d) practically straight and tangential to a circle concentric with the bezel (18) and an intermediate curved segment (22e) with its center of curvature inside the bezel (18) but of radius substantially smaller than that of the bezel. The shape of the spring (22) permits the forces necessary to rotate the bezel (18) in the two directions to be made practically equal.
