Patent ID: 7443769

Claim:
A timepiece including a striking mechanism with a striking work which includes a mobile part moving when the striking work is released, the timepiece further including a time-setting mechanism which cooperates with a winding stem, the time-setting mechanism including a time-setting lever, which pivots between an angular rest position and an angular time-setting position, and a pull-out piece, whose pivoting is controlled by the time-setting lever, between a winding position and a time-setting position, the pull-out piece controlling the axial sliding of a sliding pinion from a winding position to a time-setting position, the timepiece including a locking lever, which cooperates, via a first arm with the mobile part of the striking mechanism and via a second arm with an element of the time-setting mechanism such that, when the mobile part moves after the striking work has been released, the locking lever pivots to a locked time-setting position wherein the time-setting mechanism is locked, wherein the time-setting lever includes a control member that causes the locking lever to pivot to a locked striking work position, when the time-setting lever pivots to the time-setting position and wherein the locking lever includes locking means that cooperate with complementary means of the striking mechanism to prevent the release thereof, in the locked striking work position.
