Abstract:
1. A time-setting member connected to set a time indicator of a timepiece, wherein the indicator is driven during normal use by a mechanism controlled by a gear train of the timepiece, wherein the mechanism is arranged to uncouple the gear train from the indicator when the time-setting member is actuated, and action of the time-setting member causes the indicator to move forward through a step of one hour, wherein the time-setting member includes a push-button disposed to control, via a lever, a rack provided with toothing, wherein, when the push-button undergoes manual pressure, the rack controlled by the push-button actuates a first device that in turn acts on the mechanism to uncouple the gear train from the indicator, wherein the mechanism controlled by the gear train includes a first wheel meshing with the gear train; and a second wheel coupled to the first wheel by a spring device and driven by the first device activated by the push-button when the push-button is actuated to uncouple the first wheel and the second wheel from each other and to move the time indicator forward one step, and wherein the first device includes a sliding wheel provided with toothing, wherein the toothing of the sliding wheel meshes with the second wheel when the push-button is actuated, and the sliding wheel carries a pinion whose toothing meshes with the toothing of the rack controlled by the push-button.
