A movable decorative element, intended to be freely rotated and translated between two walls (5, 6) whose inner faces are parallel to each other, at least one of which is transparent, includes a precious or semi-precious stone (2) mounted in a socket (1). The socket (1) includes a closed bottom (4) whose outer face is bulged to promote the rotation of the decorative element when this bulged outer face (7) is applied against the inner face of one of said walls, and an open outer (7) opposite to the bottom (4) which is flush with or which protrudes relative to the stone (2) to form a bearing surface against the other of said walls (5, 6) when the decorative element is disposed between the two walls. The precious or semi-precious stone (2) is held in its socket (1) by a plurality of arms (3) which extend above a body (8) of the socket (1) and which crimp the stone (2), these arms (3) leaving, therebetween and above the body (8) of the socket (1), lateral openings (9) letting appear the flanks of the stone (2) between the arms (3), and said bearing surface is constituted by the free ends of said arms (3) in the form of separate contact areas spaced from each other around the periphery of the open outer face (7) of the socket (1).

A watch including a dial including a fixed portion superimposed on a portion movable in rotation including a surface on which are arranged areas with visual appearances different from each other, the fixed portion including at least one through opening emerging on at least one of the areas, the movable portion being kinematically connected to a control member so as to be rotated by actuating the control member and being configured so that when it is rotated, the areas of different visual appearance appear successively through the opening.

A dial for a timepiece, such as a watch, includes at least one three-dimensional decoration offset away from a base plate which forms part of the dial. The decoration is mounted on the base plate by an assembly of elements including a fixing screw, a support bar including a proximal end secured to the base plate by the fixing screw and a distal end attached to a first point of the lower surface of the decoration, a support foot including a proximal end held in a fixed position in the plate of the base plate and a distal end attached to a second point of the lower surface of the decoration, and a spacer which forms a lateral connection between the fixing screw and the support foot, the spacer being secured with the support bar to the base plate by the fixing screw.

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 decorative, wearable system includes at least one decorative element mechanically and moveably suspended in a liquid by mechanical fixation elements. The liquid shares a substantially similar refraction index as at least one of mechanical fixation elements.

The invention relates to a watch having a variable dial, and more specifically a watch that provides the wearer with the possibility of partially changing the appearance of the dial. According to the invention, the watch has a dial (1) that has at least one opening (6, 7) occupied by a removable bezel (3, 5) and the watch further has a plurality of carrying arms (9, 10) disposed radially on a carousel (8), each arm end situated on the circumference carrying a bezel (3, 5) and the carousel (8) being able to rotate about an axis perpendicular to the plane of the dial (1) and passing through the center thereof.

The invention relates to an article of jewelry comprising a transparent wall which forms a housing provided to receive a precious or semi-precious stone which is immersed and movable in a substantially transparent liquid in the housing and at least one piece which is movable in the liquid and which has the same refractive index as the liquid, the piece immersed in the liquid being substantially optically indiscernible. The housing is delimited by two walls the internal faces of which are preferably mutually parallel, and the stone is inserted into the piece in order to form a movable decorative element, the piece immersed in the liquid being substantially optically indiscernible and comprising an axis of revolution and two guiding surfaces which are adjacent to the internal faces, respectively, and which allow the movable decorative element to move freely in terms of translation and rotation in the liquid about the axis of revolution inside the housing.

A construct (10) is provided having an aesthetic form adapted to please a wearer and to be worn by the wearer. The construct provides a structure on which functional elements are integrated. The functional elements include several elements. A first element is a fluid reservoir. A second element is at least two fluids (12, 14) disposed in the fluid reservoir. A third element is a motion generator (22) having a state in equilibrium with respect to an attraction force and a further attraction or repulsion force when the construct is at rest, the motion generator causing an animation effect when the construct is moved relative to an attraction or repulsion force.

The invention relates to a timepiece having a rotary control member, the rotary control member having a hollow cylindrical body coaxial with the axis of rotation of the rotary control member, the hollow cylindrical body defining a hollow inner housing having or supporting a coaxial rotary disc on which is arranged a rotatable mark or logo motif visible from the exterior of the timepiece. The rotary disc rotates freely about its axis in or on the hollow cylindrical body, the rotary disc cooperating with a displacement device comprising an asymmetrically distributed weight to create an imbalance tending to rotate said rotary disc about its axis when the timepiece is in motion or when the control member has been rotated, so that, seen from the outside, the motif maintains a substantially fixed orientation.

The invention relates to a watch having a variable dial, and more specifically a watch that provides the wearer with the possibility of partially changing the appearance of the dial. According to the invention, the watch has a dial (1) that has at least one opening (6, 7) occupied by a removable bezel (3, 5) and the watch further has a plurality of carrying arms (9, 10) disposed radially on a carousel (8), each arm end situated on the circumference carrying a bezel (3, 5) and the carousel (8) being able to rotate about an axis perpendicular to the plane of the dial (1) and passing through the center thereof.
