Abstract
A timepiece including a movement, a mechanism controlling the power reserve of a drive means with an arbor whose angular position indicates said available torque, a striking mechanism controlled by a striking mechanism control mechanism, and a locking lever arranged to lock said movement. The timepiece includes a selective stop mechanism according to the drive torque available in the drive means, which manages said available drive torque by limiting or not limiting the operation of all of part of the striking works of said striking mechanism, by a transmission mechanism controlling an isolating wheel set controlling the position of said locking lever and arranged to release or prevent the movement of a striking mechanism control rod linkage and/or to allow or prevent the strike of a hammer on a gong.
