Abstract: Device for articulation of two timepiece components (10, 20) including first and second timepiece components connected to one another in an articulated manner using at least one articulation pin (1), wherein the two timepiece components each include first and second guide surfaces that cooperate with first and second articulation surfaces (1a, 1e) respectively of at least one articulation portion of the at least one articulation pin (1), the guide surfaces and the respective articulation surfaces being positioned face-to-face to guide by rubbing the movement in rotation of the respective timepiece components (10, 20) relative to the at least one articulation pin (1), the at least one articulation portion of the articulation pin (1) or the at least one articulation pin (1) being made entirely of ceramic, the at least one articulation pin (1) including at least one portion of lower strength positioned out of reach of the guide surfaces of the respective timepiece components, and the at least one articulation portion of the articulation pin (1) or the at least one articulation pin (1) including an entirely continuous peripheral surface with no sharp edges, or any section of the at least one articulation portion or of the articulation pin (1) on a median longitudinal plane and any section of the at least one articulation portion or of the articulation pin on a transverse plane having a contour of continuous shape.

Abstract: A clasp for a wristlet has at least two movable blades (4), (5) articulated with respect to one another about an axis of the blades (51) and a locking device (10) making it possible to lock or unlock a first blade (5) relative to a second blade (4), respectively in closed and open configurations of the clasp. The locking device (10) is linked to the first blade (5) and has an actuation lever (2) intended for the actuation of the locking device by a user, a locking element (1) capable of cooperating with a complementary locking element (4a) of the second blade (4), and an intermediate element (3) linked to the locking element (1) by a first link device and to the actuation lever (2) by a second link device, at least one of these two link devices being provided with at least two degrees of freedom.
