Abstract
The gear train (1) connecting the driving element (3) to the minute wheel (2) includes a wheel and pinion (5) able to be disconnected from this train to interrupt the movement and stop the hour (23) and minute (22) display when the time-setting stem (8) is actuated while in a pulled out position (21). The disconnectable wheel and pinion (5) then undergoes a movement of translation which removes it from the other wheels and pinions (4, 6) of the train (1), the axes about which all the wheel and pinions rotate remaining substantially parallel to each other.
