Watch with a striking mechanism having a governor and time setting safety function

A watch with a striking mechanism having a governor, comprising a time setting mechanism with a setting means arranged to drive, in its coupling position, a motion work lever able to occupy a coupling position and an uncoupling position, a movement comprising an output for releasing the passing strike by the movement and arranged to drive at least one reference wheel set, and said striking mechanism comprising at least one control piece arranged to be set in motion by said output or on user command, and to read position information on said at least one reference wheel set, said striking mechanism further comprising a governor mechanism arranged to regulate the rotational speed of at least one striking function actuator to a substantially constant value, wherein said striking mechanism comprises, for at least one said control piece, a governor trigger piece, which is distinct from said control piece and arranged, according to the kinematics of said control piece, to operate a governor stop jumper able to block or allow the rotation of said governor mechanism, and, by means of an articulated connection, to isolate said motion work lever in said uncoupling position or place it in said coupling position, said governor trigger piece forming an intermediate part arranged to allow said control piece to simultaneously release said governor mechanism and uncouple said motion work lever.
