Abstract: An arrangement includes two components (3, 4; 3?, 4?) of a timepiece component and an axis of rotation (A1; A1?), the two components (3, 4; 3?, 4?) being linked to one another by an elastic articulated link (100; 100?) about the axis of rotation (A1; A1?), the arrangement also includes an elastic element (10, 10?; 10?) such that the relative movement of the two components (3, 4; 3?, 4?) takes place against the elastic element (10, 10?; 10?), wherein the elastic element (10, 10?; 10?) includes at least two superposed springs (10a, 10b, 10a?, 10b?; 10a?, 10b?), each of these at least two springs (10a, 10b, 10a?, 10b?; 10a?, 10b?) taking the form of a distinct element.

Abstract: A watch spring (1) for a first component (2), more particularly for a bezel or for a case middle or for a case back, intended for the detent of the first component (2) relative to a second component (3), the spring (1) comprising at least one first connecting element (10a) intended to interact with at least one second connecting element (20b) provided on a component (2b) of the first component so as to connect the spring and the component, the at least one first connecting element comprising at least one elastic connecting arm (10a) extending in a first direction (D1), the at least one first connecting element being intended to receive a force (F) for driving the first component relative to the second component in the first direction or substantially in the first direction.

Abstract: A device for adjusting the length of a wristlet includes: a cover (10); a link element (40) designed to be connected to a wristlet strand (9) and mounted movable relative to the cover (10) in the longitudinal direction in which extends a wristlet strand to be connected to the adjusting link element, such that this displacement of the adjusting link element (40) relative to the cover (10) enables lengthening or shortening the length of a wristlet strand; an actuating device (30) arranged on the cover (10) movable relative to the cover in at least the longitudinal direction; and a kinematic connection connecting the actuating device (30) and the adjusting link element (40), such that the actuation of the actuating device (30) in at least the longitudinal direction relative to the cover (10) can bring about the longitudinal displacement of the adjusting link element (40) relative to the cover (10).

Abstract: Device for adjusting the length of a bracelet, having a guidance and fastening system (10, 30, 40, 50), including at least one adjusting link element (23) mounted with the ability to rotate about an axis of rotation (A1) defined by a guidance device of the guidance and fastening system. The guidance and fastening system (10, 30, 40, 50) includes an elastic fastening device comprising an elastic property in order to perform an elastic fastening function. The two guidance and elastic fastening devices are arranged around the axis (A1), notably upon implementation of the fastening function. The elastic fastening device provides elastic immobilization of an end link element (25) connected to the adjusting link element (23), particularly relative elastic immobilization of the said end link element (25) with respect to the adjusting link element (23), or of the adjusting link element (23), in at least one configuration of the adjustment device.

Abstract: Device for adjusting the length of a bracelet, having a guidance and fastening system (10, 30, 40, 50), including at least one adjusting link element (23) mounted with the ability to rotate about an axis of rotation (Al) defined by a guidance device of the guidance and fastening system. The guidance and fastening system (10, 30, 40, 50) includes an elastic fastening device comprising an elastic property in order to perform an elastic fastening function. The two guidance and elastic fastening devices are arranged around the axis (A1), notably upon implementation of the fastening function.
