Abstract: A timepiece, includes a frame supporting a drive element, a time base and drive trains pivotably mounted on the frame and arranged so as to drive at least one display train intended to carry an element displaying information, such as the time. The movement also includes a fixed gear, firmly attached to the frame, with which a toothed element of the display train is arranged to mesh, and a drive element having first and second kinematic links, respectively, with one of the drive trains and with the toothed element so as to drive the latter in translation in a first direction along the fixed gear. Preferably, the drive element is embodied in the form of a deformable element, and the movement also includes a retrograde mechanism for driving the toothed element rapidly in the opposite direction by means of the drive element.

Abstract: Two rotating parts (11, 15) rotatably fitting on an axle (10) which passes through the opening (9) surrounded by the frame (4) are provided in a rectangular frame (4), the first rotating part (11) surrounding the elongated second rotating part (15) in a fork-like manner. The first rotating part (11) and the second rotating part (15) may each assume two fixed positions 180° apart, in which they are locked to the frame or to the first rotating part (11). By turning the rotating parts (11, 15), the outside of the jewellery element (2) can be changed. Jewellery elements can also be combined to form chains, which can be used, for example, as watch straps.
