Abstract
A timepiece includes a movement, a main striking mechanism, a secondary strike release mechanism, and a mode selecting mechanism. The main striking mechanism is controlled by a main strike control mechanism, arranged to release strikes, at times programmed by the movement, or on demand, and a sequence of each strike is determined by information gathered by feeler spindles on snails or time references driven by the movement. A coupling mechanism of the secondary strike release mechanism actuates a control rod linkage of an isolating mechanism arranged to isolate various different release mechanisms for different strikes using the main striking mechanism to play strikes. The isolating mechanism includes at least a first isolator which, in a first winding position, takes a stop position preventing the spindles from gathering information from the snails, and, in a second let down position, allows the spindles to pass to come into contact with the snails.
