Abstract
The invention proposes a timepiece comprising a repeater striking mechanism (14), wherein the striking mechanism (14) comprises a release lever (24) fitted with a click (26) which is pivotably mounted on the release lever (24) and which meshes with the teeth (27) of a ratchet detent wheel (28) such that, during automatic release, a release cam (16) causes the release lever (24) to pivot towards the detent wheel (28), characterized in that the striking mechanism (14) comprises a winding cam (34), which cooperates with a shoulder (36) associated with the release lever (24) to control the winding thereof, in that the release lever (24) is restrained in its wound position, by a locking device (42), and in that the release cam (16) releases the striking mechanism by unlocking the locking device (42).
