A platform for displaying several mutually different horometric items of information, includes as many crowns as the horometric items of information to be displayed on the platform. Each of the crowns is arranged to receive an associated information support and is movable in rotation at a speed selected according to a horometric item of information displayed on the associated information support.

The present invention relates to a timepiece comprising a case, in which an electronic module supplying at least one item of information is arranged, wherein said at least one item of information is displayed on a dial by display means, characterised in that the electronic module additionally comprises a communication unit having an optical receiving device, wherein said optical receiving device comprises at least one photoelectric receiver arranged to face a first aperture formed on the dial so that an optical signal can be received by said optical receiver.

A centralized control unit for controlling an arm moving in a clockwise direction and in a counter-clockwise direction includes an arbor about which the centralized control unit pivots. The arm is integrally mounted on a toothed actuating wheel as an assembly, and the assembly is mounted to freely rotate about the arbor. The centralized control unit also includes a wheel to control the arm in the clockwise direction, a wheel to control the arm in the counter-clockwise direction, and a power wheel kinematically connected to an independent barrel to drive the arm.

A single-hand or single-indicator timepiece that can simultaneously identify both the hour and minute portion of a given time is present herein. The timepiece includes an indicator structured to rotate about the face of the timepiece and point to the hour element of the time via a distal end thereof. In addition, the same indicator includes a minute identifying portion disposed along a length thereof that will align with a rotationally disposed minute disc. The minute disc includes indicia representative of the minutes evenly spaced radially about its surface in a clockwise ascending order. As the minute disc rotates counterclockwise and the indicator rotates clockwise, the indicator will simultaneously identify the hour element at its distal end and the minute element via the relative position of the minute identifying portion and the minute disc.

A display system is provided, configured to be integrated in an accessory to be worn by a wearer/user as an article of clothing, an item of jewelry, a wristwatch, a pocket watch or any other fashion item. The display system includes: (a) a source of electrical energy, (b) one or more light sources, (e) a source of mechanical information, visual animation or visual presentation, (d) a transformation device for transforming such information or visual animation into a luminous information or visual animation, and (e) a control device adapted to allow the user/wearer to control the activation of the system. In this manner, the system is able to provide a luminous information, visual animation or visual presentation.

A timepiece with alternating color rotating dial preferably includes a timepiece housing, at least one mounting plate, a hubbed spiral disc, a hubbed drive system, a geared spiral disc, an outside drive system, a clock module and a control module. The at least one mounting plate is attached to the timepiece housing. The hubbed drive system preferably includes a hubbed motor, a hubbed drive gear and a central gear. The hubbed drive system rotates the hubbed spiral disc. The outside drive system preferably includes an outside motor, at least one outside drive gear and an outside double-wide drive gear. The outside drive system rotates the geared spiral disc. The geared spiral disc rotates within the hubbed spiral disc. The control module controls the rotation of the geared spiral disc relative to the hubbed spiral disc.

Jumper device (80) for a timepiece device (100) including at east one first arm (81) including a first beak (81a) for positioning a first mobile unit (10), at least one second arm (82) including a second beak (82a) for positioning a second mobile unit (20), an elastic element (84) for returning the first arm and the second arm to configurations positioning the first and second mobile units, and a lever (83; 83) interfaced between, on the one hand, the elastic return element, and on the other hand, the first and second arms.

A horological display mechanism (100) including first drive elements (1) for rotating a first display wheel set (10) through a first number of steps in order to display a first magnitude, and second drive elements (2) for rotating a second display wheel set (20) through a second number of steps in order to display a second magnitude, this display mechanism (100) comprises coupling elements (3), separate from the first drive elements (1) and from the second drive elements (2), and which are arranged to index the first display wheel set (10) and the second display wheel set (20) relative to one another, to ensure their alignment, in an alignment direction (A), in a display area (30). The invention further relates to a timepiece (1000), in particular a watch, including such a display mechanism (100), in particular a calendar mechanism.
