Abstract (en)
[origin: WO9210794A1] The wristwatch displays the date through a window in the dial. To achieve this, the watch comprises a rotatable disc (13) bearing a first series of numbers corresponding to some of the days of the month, and a second series of numbers corresponding to the remaining days, said series being arranged in two concentric circles. To ensure that the date numbers pass the hatch in chronological order, the disc is rotatably driven by a motor (70) combined with an endless screw (71), and translatably driven by a motor (72) combined with an endless screw (73) to pivot a circle sector (74) about a spindle (75). Both said motors are controlled by an electronic circuit (76).
