Abstract: A gong for a striking mechanism in a horological movement comprises a first end mounted to a heel and a second end that is free. The first end and the second end define a longitudinal axis along the length of the gong, wherein the gong has a cross-section size that is variable along all or part of its longitudinal axis including an end section of the gong that comprises the free end.

Abstract: A watch movement with a mechanical source of energy is provided. In one implementation, the watch movement comprises a frame intended to support moving parts and defining upper and lower faces. The distance between the upper and lower faces may define a movement thickness. Further, springs may be provided for storing the energy, each being housed in a barrel. At least three barrels may be provided, the first and the second of which are superposed and the third of which is placed laterally to the other two and within their thickness.

Abstract: A damping device, more particularly for a watchcase, includes a case (1) the back (7) of which has an extension provided with a groove (13) holding a gasket (14). The device further includes a support (2, 3) the lower segment (2) of which has a compression chamber (18) cooperating with the extension of the back of case (1), this extension being able to move axially, and in air-tight fashion, in this chamber (18). This lower segment (2) of the support is linked to a ring (3) against which case (1) leans in its rest position.

Abstract: An automatic pawl winding mechanism for a watch movement has a rotor solidly attached to a rotor wheel and oscillating about the axis of a rotor pivot, a pawl wheel to which an oscillating motion of rotor is transmitted by the rotor wheel being pivoted about the axis of a pawl wheel shaft, at least one pawl being eccentrically attached to the pawl wheel shaft, and an automatic wheel cooperating with the pawl or pawls. The oscillating motion of the rotor wheel is thus transformed into a unidirectional rotary motion of the automatic wheel, and this rotary motion is transmitted to a ratchet wheel via a transformation gear train. The rotor, the gear train from the rotor with rotor wheel to the pawl wheel with the pawl or pawls is mounted on an independent rotor bridge while no other organ of the mechanism is mounted on this bridge.

Abstract: Device for fixing a watchband to a watch container includes a hinge connected to the watch container with two pivots sliding therein and a fixing element fixed to or integrated into the end of the watchband provided with two brackets defining a space therebetween for arranging the hinge. Each bracket has an axial recess protruding in the space between the brackets. The axial recess is extended in a direction of the external side faces of the brackets through an orifice containing an end stone mounted such that it is slidable in the recess and exposed to the action of a second return spring which pushes a press button fixed to the external ends of the end stone towards outside. The hinge is provided on the side faces thereof with an annular chamber having a slot which defines a privileged direction.

Abstract: A securement device for a bracelet includes a first attachment (2) and a second attachment (3) adapted to receive a bracelet pin (8). At least one of the attachments (2, 3) includes an axle (22, 32) substantially parallel to the pin (8), this axle (22, 32) being adapted to be disposed slidably in a transverse bore (10) of a body (1) that receives bracelets. Moreover, the device includes a locking element (4) disposed in a hole (12) in the body (1) intersecting the transverse bore (10) so as to coact with at least one axle (22, 32) of the attachments (2, 3) in a way to permit the locking and unlocking of at least one of these attachments (2, 3) in their recess.

Abstract: The watch comprises a case (9) with a fixed part (10) in the shape of a bracket (20) and a mobile part (11) with a middle (21) and a movement (23) mounted onto the fixed part (10) so as to be able to swivel about a swivel axis (32) thanks to pivots (31) in order to realise a tilting motion of the mobile part (11) in two opposite directions. Two actuating mechanisms (44, 45) are mounted into the middle (21) and intended to transform the tilting motions into an action upon two control organs of functions of the movement that may be of the chronograph type. One thus obtains a watch without push-pieces, functioning precisely, having great stability and easy manipulation.

Abstract: The present invention refers to a lunar phase display mechanism including an upper disc which is the lunar display disc and a lower disc mounted concentrically to this disc which is the lunar disc. One of the discs is mounted in such a way that during normal operation of the mechanism it rotates relative to the other disc. This other disc is mounted in such a way that it is in a stationary position during normal operation of the mechanism while this position can be changed by a rotary motion. Alternatively, the gear train driving the rotating disc can be so designed that the direction of rotation of this disc can be reversed. In this way the different appearance of the lunar phases at the latitudes of the earth and in particular in the northern and southern hemisphere can be taken into account in the display.
