A watch is described, in particular a wrist watch, having a housing (1), having a dial (3) arranged in the housing (1), having at least one endless conveyor (8), which is guided around two deflection guides (7) having deflection axes parallel to the dial (3), for at least one hand (5), and having a drive for the endless conveyor (8). To provide advantageous structural conditions it is proposed that the dial (3) extending between the two sides of the endless conveyor (8) be mounted on a mount (11), which is either provided laterally outside the orbit of the hand (5) or is fastened laterally outside the orbit of the hand (5).

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 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.

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.
