Abstract

During normal use, the time indicator (2) is driven by a mechanism (3) controlled by the gear train (4) of the timepiece. This mechanism is arranged for uncoupling the gear train from the indicator when the time-setting member (1) is actuated, this action causing the indicator to move forward through a step of one hour. The time-setting member includes a push-button (5) which actuates a device (6) that in turn acts on said mechanism (3).
