Abstract (en)

[origin: EP1936448A2] The device has a base wheel of a horological movement controlling the display of a unit, indicating time or functioning of a timepiece. A lever (10) is held in standby position by a spring being actuated manually on demand, by using a push button placed outside the timepiece, so as to turn a rack (12) on its axis until the moment a finger of the rack abuts against a cam. The rack in its rotation drives a pinion carrying the unit indicating the time. The cam includes a configuration corresponding to a series of values to be displayed.
