An arrangement for the holding and vibration transmission of an acoustic radiating membrane (10) in a striking or musical watch (1) case (2). The case includes at least one crystal (3) mounted on a middle (4) and a back (5) mounted on a side opposite the middle. The acoustic radiating membrane is held in a portion of the watch case, such as the middle by at least one connection part (12) disposed between a peripheral rim of the membrane or an edge element (11) of the membrane and the middle by acting for the holding of the membrane in a direction parallel to the plane of the watch. The connection part may be a screw screwed into a threaded opening (14) of the middle and coming into contact with the edge element of the membrane.

A safety device for a striking-work including a first wheel, a second wheel and an actuating member. The first wheel is meshed which drives it in rotation about a shaft and it includes an abutment member. The second wheel is also in rotation about the shaft and is in contact with the abutment member. The second wheel includes a portion configured for an actuating member to act on the intermediate portion so as to move the second wheel.

A regulator for a striking mechanism of a mechanical watch including a base, which can be assembled in a fixed manner with regard to the housing and which rotatably mounts a rotary wheel. At least two mass elements are arranged on the rotary wheel and by way of a rotation of the rotary wheel are deflectable radially outwards counter to a spring force on account of the centrifugal force, in order to regulate the rotation speed of the rotary wheel. At least three bearing elements are attached to the base, the bearing elements engaging peripherally on the rotary wheel, in order to mount this relative to the base.

A striking mechanism for a watch including an hour snail driven by a movement, a strike wheel set including a detent ratchet and a repeating rack pinion, a pivoting hour-rack for reading the snail and driving the pinion, a click set in motion at each passing strike to drive the detent ratchet, with a mode selector mechanism for selection by the user of a particular strike mode, among distinct modes including a silent mode, defining the angular position of a cam having an external profiled surface, wherein, in silent mode, the largest radius pushes back a beak of a silencing lever, to orient it into a position where its main arm moves the click away from the ratchet in order to disable every passing strike function.

A timepiece with a striking mechanism having a detent ratchet cooperating with a passing strike actuation click controlled by a movement or a repeater click operable by a user, including an uncoupling lever preventing access of the click to the ratchet under the action of a reversing lever operable by a hand-setting stem, or by a main strike function or tune selection control member, or by a stopping mechanism, and including a safety device for preventing release during a strike mode or tune selection, arranged to prevent the release of any strike function by the movement or by a user, and which includes a release-prevention lever, the pivoting of which, under action on the main control member, moves any click away from the detent ratchet.

The gong is made with a wire or a strip having an atypical shape for a watch striking mechanism. The gong includes a rectilinear part connected to a curved part. The rectilinear part and/or the curved part are connected to the same gong-carrier. The gong includes several notches made at defined geometric points on a portion of the length of the gong to adapt the natural vibration frequencies within an audible range between 1 kHz and 5 kHz, so that the sound produced by the vibrating gong is harmonious.
