Abstract: The timepiece comprises at least one pushbutton (9), at least one control member actuable by the pushbutton (9) and a device (10) for locking the pushbutton (9), and is characterized in that the locking device (10) is arranged to permit the pushbutton (9) to occupy an unlocked axial position, from which it can be pressed to actuate the control member, and a locked axial position, nearer the interior of the timepiece than the unlocked axial position and in which the control member is not actuated.

Abstract: The timepiece comprises a case (1), a mechanism (6) disposed in the case (1) and a rotatable control member (10) manipulable by a user, and is characterized in that the rotatable control member (10) is movable in translation relative to the case (1) in a direction substantially perpendicular to the axis (A) of the rotatable control member (10), between first and second positions, and in that in at least one of these first and second positions a rotation of the rotatable member (10) controls a function of the mechanism (6).

Abstract: A watch having a rotating bezel associated with a system of axial ratchets and a ring allowing the rotating bezel (2) to be snap fitted onto the middle part (4) and assuring the functions of centring, holding and angular positioning said bezel. The ring (8) has a substantially U-shaped cross section, a lower side of which is fixed to a middle part by being driven onto said middle part and the other side of which has a prominent surface (20) onto which the bezel (2) is mounted. The ratchets are formed by flexible strips (26) cut into the flat base (18) of the ring (8). The system may be simply and inexpensively manufactured and mounted.

Abstract: The extensible bracelet clasp is of the unfolding buckle type. It includes a first assembly (1) comprising a cap (3) and a push-piece (5) adapted to slide on a second assembly (2) in order to adjust the length of the clasp. Such second assembly (2) comprises an arrangement (15) on which the push-piece (5) can act in order to open the clasp, such arrangement (15) and such push-piece being respectively provided with indexing means (16) and positioning means (17) in order to permit adjustment in length of the clasp and to retain the memory of such adjustment when the clasp is opened. The clasp can be used for a watch bracelet.

Abstract: A bracelet clasp of the unfolding buckle type comprises a base plate (1) on which at least one hinged plate (2) is capable of being folded. A device enabling the two plates to be locked onto each other in a closed position comprises a first tongue (4) raised on the base plate (1) and a second tongue (5) raised on the hinged plate (2). In a closed position the two tongues are situated back to back and head to tail. The existence of a double tongue enables the locking force of one plate on the other to be doubled.

Abstract: An adjustable link (1) for a bracelet having a plurality of fixed links comprises a cap (6) into which a base (7) slides and a mechanism (8) with push-pieces (9, 10) which enables the length of the link to be extended to at least two different lengths so as to enable the length of the bracelet to be adapted to the variations in diameter of the wrist wearing it. The link may be incorporated in a bracelet carrying a watch.
