A watch striking mechanism, the mechanism including: a gong, which is connected to a gong-carrier, a hammer for striking the gong at predetermined times, a damper counterspring for keeping the hammer at a distance from the gong in an idle mode, and a drive spring for the hammer, which includes a fixed end and an end that is free to move, said drive spring being able to be wound to drive said hammer against the gong in a strike mode in order to produce an acoustic sound, wherein the striking mechanism includes a locking device provided with at least one bolt, which is intended to lock the hammer in an idle mode, and to be moved away from the hammer in a strike mode, when the drive spring is wound, the locking device being arranged such that the drive spring drives the hammer to strike the gong for a first time before the bolt locks the hammer in the idle position following the first strike.
