Abstract: Bracelet provided with a foldable clasp, comprising a first arm (7), at least a second arm (8) articulated with said first arm, a cover (4, 6), under which the arms' free extremities are folded back when the clasp is closed. The cover comprises a locking system enabling the arms to be held in a closed position and to be released by acting manually on the locking system to open the clasp. It further comprises a casing (4) and a base (6) closing the cover's lower side. The casing comprises solid sides of uneven thickness obtained by detach cutting machining or by molding. The casing's sides define between them and with the base an internal volume (45; 95) in which the locking system is at least partially accommodated.

Abstract: Timepiece component (1) having a grande date display wherein the two discs are actuated independently from one another by stepping motors. The date's tens are displayed differently, for example in another color, in the morning and in the afternoon. It is also possible to combine the date indications with other independent indications.

Abstract: Regulating element for wristwatch comprising: a balance, a magnetic return member for returning the balance to at least one stable equilibrium position, and an escapement for maintaining the oscillation of the balance around the equilibrium position.

Abstract: Method for producing a micro- or nano-mechanical part, for example a pulley or belt for clock/watch making, comprising a laser ablation step which is performed with the aid of a femtolaser, i.e. a laser having a pulse with a duration of less than 5×10?13 seconds and a power greater than 1012 watts on the beam/material interaction surface. The part to be machined is pre-modeled in three dimensions and said three-dimensional model is used to generate the machining program.

Abstract: Clasp with unfolding buckle for wristlet, having: an inside blade (3), two outside blades (1) forming an articulated shank with the inside blade, two push-pieces (7) capable of being actuated transversely against the action of an elastic element (9) for unlocking the clasp, at least one stopping (11) connected removably to said push-piece (7) for limiting the amplitude of displacement of said push-piece along at least one axis.

Abstract: Electronic watch with a segment display with LEDs, wherein precious stones or synthetic stones or gemstones made of glass are arranged in front of the display segments so as to display digital or alphanumeric symbols by lighting up stones by means of the corresponding light sources.

Abstract: Regulating element for wristwatch comprising: a balance, a magnetic return member for returning the balance to at least one stable equilibrium position, and an escapement for maintaining the oscillation of the balance around the equilibrium position.
