The timepiece includes: a main plate provided with external teeth extending in a circular-arc shape with a central axis O as a center; a rotating plate rotatable around the central axis O with respect to the main plate; a first gear rotatably supported on the rotating plate; a transmission gear train rotatably supported on the rotating plate, meshing with the external teeth and the first gear, and configured to transmit, to the first gear, rotation of the main plate with respect to the rotating plate; and a first front decorative body non-rotatably connected to the first gear and displaceable with respect to the rotating plate.

A moving mechanism for a decorative element of a timepiece including a circular drive element arranged to be rotatable about a central axis, the decorative element being mounted on the drive element with an arbor integral with the decorative element and parallel to the central axis, and first device for driving the decorative element in a rotational motion about its own arbor and/or in a translational motion along its own arbor, the first drive device for the decorative element being mounted on the circular drive element and arranged to cooperate with fixed actuation device arranged in the periphery of the circular drive element such that the decorative element rotates about its arbor and/or moves along its arbor while rotating about the central axis.

Horological display mechanism (100) for a timepiece (1000), comprising at least one three-dimensional display support (10), which is arranged for the simultaneous display of at least a first variable on a first three-dimensional display (901) under the action of a first control mechanism, and of a second variable on a second three-dimensional display (902) under the action of a second control mechanism, wherein the first display (901) surrounds the second display (902), or vice-versa, and wherein the first control mechanism and the second control mechanism are capable of being manoeuvred independently of one another, and constitute separate mechanisms, one for controlling the translational motion and the other the rotational motion, or vice-versa.

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.

Horological display mechanism (100) for displaying variables on separate unit display supports (10), each enclosing a display indicator (901; 902) which is a first display (901) capable of moving in translation, or a second display (902) capable of moving in rotation, all of these unit supports (10) comprise indicators (901; 902) of the same kind, which are either first displays (901) for displaying a first variable, or second displays (902) for displaying a second variable, or both first displays (901) and second displays (902), all visible to the user, the display mechanism (100) comprises a control mechanism (300) arranged to drive wheels or rod systems for driving the different display wheel sets and comprises a first carrier (111) for driving, by itself, all of the first displays (901), and/or a second carrier (112) for driving, by itself, all of said second displays (902).

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 moving mechanism for a decorative element of a timepiece, the decorative element including at least two decorative faces disposed around an arbor defining the axis of the decorative element. The moving mechanism includes a circular drive element arranged to be rotatable about a central axis and including an aperture arranged to reveal one of the decorative faces of the decorative element and inside which said decorative element is mounted to rotate about its arbor. The moving mechanism also includes first device for driving the decorative element in rotation about its arbor mounted on the circular drive element and arranged to cooperate with fixed actuation means provided in the periphery of the circular drive element, such that the decorative element rotates about its arbor to successively display its decorative faces in the aperture of the circular drive element while rotating about the central axis.
