Abstract
Date display device, intended to be fitted to a timepiece provided with a movement, a dial 10 and hands 12, 14 driven by said movement and displaying the time. A date mechanism, drives first 32 and second 34 display members, mounted to move in rotation on the movement, and provided with indices 24 26. The device is arranged so that, when the mechanism causes the units display to pass from a value n to n+1, n being an integer number comprised between 1 and 9, the first member 32 travels, in the clockwise direction, through an angle equal to 30°, and so that, when n is equal to 1, the index 24 is located in a position corresponding to the position which an hour hand would occupy, when it is one o'clock.
