Abstract
Timepiece including a main strike control mechanism for releasing strikes at programmed times or on demand, and a mechanism for releasing, at a particular time, a secondary strike control mechanism including a coupling mechanism allowing the exclusive operation, at a given time, of one or the other. The timepiece includes a device for selecting the secondary strike or main strike mode, by winding, in the secondary strike mode, the coupling mechanism to uncouple the main striking mechanism and to couple the secondary striking mechanism. In the main striking mechanism mode, the coupling mechanism uncouples the secondary striking mechanism using the main striking mechanism, either not to play the secondary strike, or to play the secondary strike by a mechanism other than the main striking mechanism.
