An oscillating winding mass (1) for a movement of a timepiece, the oscillating winding mass (1) being intended to be rotatably mounted on an axis of the movement. The winding mass includes a main element (2) and a decorative element (10), for example a logo or an acronym, a part of the winding mass (1) forming a heavy part (3) allowing the oscillation of the mass (1) in response to the movement of the timepiece and to the force of gravity, the main element (2) giving the general shape of the oscillating winding mass (1), the decorative element (10) being mechanically linked to the main element (2), the decorative element (10) being rotatably mounted on the main element (2).

The present invention relates to a mechanical stop and start system for a function of a timepiece, comprising a mass, mounted so as to be able to move on a frame, between a first and a second end position, these being defined respectively by a first stop and a second stop, said mass moving in a bistable manner, under the effect of gravity, tensioning a spring between the first and second end positions, and relaxing said spring between the second and first end positions.

A self-winding mechanical horological movement including a pivotally oscillating weight, wherein the oscillating weight is provided with a decorative disc mounted on the oscillating weight and pivotally driven by the weight. The disc is fastened to a support that includes a stem inserted into a hole provided in the rotational shaft of the weight. The stem and the hole include non-circular section cylindrical portions corresponding with one another, so that the support and the disc are pivotally driven by the shaft. The disc forms a decoration that covers the entire surface of the movement, without requiring technical complexities. The disc can be free to undergo an axial movement in relation to the weight, so that the disc may be removed from the weight when the horological movement is dismantled from a watch case.

A timepiece includes a representation of a non-rectilinear object, the representation particularly including a movable element kinematically connected to a drive mechanism. The representation also includes at least one second movable element, the drive mechanism being arranged such that the movable elements each move, simultaneously and in synchronization, between a first and a second end position, and vice versa, the movable elements forming the representation at a first size and at a second size greater than the first, respectively, when the movable elements are in the first and second end positions thereof.

Portable jewellery piece comprising a mechanism for animating an object, said mechanism comprising: —a motive source arranged to drive a transmission; —a regulating system arranged to regulate the speed of rotation of said transmission; —a support system bearing an object that is intended to be animated according to a rotation about a first axis of rotation under the effect of said motive source via a power take-off forming part of said transmission. According to the invention, said support system comprises a first frame that is mounted so as to be able to pivot on a frame element about said first axis of rotation, and an inner frame that is mounted so as to be able to pivot in said first frame about a second pivot axis that is substantially orthogonal with respect to said first pivot axis, said object being moreover arranged so as to be driven by an eccentric driving element that is secured in rotation with a driving wheel arranged to be driven by said power take-off.

A timepiece including a dial defining an XY plane, an automaton disposed above the dial, the automaton having at least one first member and one second member, which are articulated in order to reproduce beating movements, and a driving mechanism of the automaton. The first member is provided in order to pivot about a first axis which is non-parallel to the XY plane and the second member is provided in order to pivot about a second axis which is different from the first axis. The driving mechanism of the automaton includes actuators of the first and second members, provided in order to make the first and second members respectively pivot according to non-symmetrical pivoting movements and in order to coordinate the pivoting movements of the first and second members so that the combination thereof gives a beating effect of the first and second members.
