Abstract: The device for fixing a wristband to a watch middle includes a connecting element (11) for connection to a wristband (10) or a watch middle (20), at least one pin (1) able to occupy two positions, one projecting from the connecting element (11) and another retracted into a housing (11a) of the connecting element (11), and a receiving element (21) for connection to a watch middle (20) or a wristband (10), having at least one bore (21a). The fixing device includes at least one insert (5), and is designed to occupy at least two configurations: a first configuration in which the at least one pin (1) occupies a position retracted into the connecting element (11), enabling a wristband to be separated from a watch middle, and a second configuration in which the at least one pin (1) occupies a position projecting from the connecting element and is positioned in the at least one bore (21a) of the receiving element (21), the at least one insert (5) forming an interface between the at least one pin (1) and the at least one bore (21a) and/or the housing (11a) to minimize frictional wear on rotation of the at least one pin (1) relative to the receiving element (21) and/or the connecting element (11) respectively.

Abstract: The device for fastening a strap strand to a watch middle includes a connecting element (11) for connection to a strap strand (10) or a watch middle (20), at least one pin (1), a receiving element (21), connected to the other of the watch middle (20) or the strap strand (10), and at least one insert element (2). The device is designed to occupy at least two configurations: a first configuration, in which the at least one pin (1) is free to translate within a recess (11a) of the connecting element (11), to be able to occupy a position projecting from the connecting element (11) and a position set back into the recess (11a); and a second configuration, in which the at least one insert element (2) cooperates with the at least one pin (2), to hold it in its position projecting from the connecting element (1).

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.
