A striking watch is provided with an acoustic radiating membrane made of metallic material or amorphous metal. The membrane takes the form of a loop with walls of a certain thickness to be connected by a first edge portion to a middle part of a watch case and by a second edge portion to a bezel fixed to a watch crystal. The bezel connected to crystal is movable with respect to the case middle via the membrane during the vibration of membrane once a sound is generated by a watch striking mechanism in the watch case. The membrane is configured with a wall of a specific thickness in an active region dependent on the mass of the bezel connected to the crystal, to obtain a frequency f.sub.0 of a first vibration mode.

A resonant member for a striking mechanism of a watch or of a music box includes at least one resonant part, such as one or more gongs, arranged to vibrate and resonate once activated, and an attachment part. The resonant part and/or the attachment part is made from an alloy of tungsten or tantalum or rhodium or hafnium with more than 51% of tungsten or tantalum or rhodium or hafnium in the alloy.

The invention relates to a striking mechanism, comprising striking hammers, gongs, each being arranged to produce a sound under the action of a hammer associated therewith, actuators for actuating the associated hammer, a striking control device, and at least one striking drive device arranged to engage with the control device. The invention further comprises at least one mechanism for striking multiples of n hours, n≧2, kinematically connected to said striking drive device, said mechanism for striking multiples of n hours being arranged to actuate the hammers to strike the multiples of groups of n hours according to a specific striking when said control device has been actuated.

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.
