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 fof a first vibration mode.

Striking or musical watch provided with at least one acoustic radiating membrane and method for manufacturing the membrane

A timepiece component including a shaft-like portion including at least one pivot about a pivot axis, at least the material forming this shaft-like portion is a non-magnetic alloy containing at least silver and palladium and having a Vickers hardness of more than 450 HV.

Timepiece component with a shaft-like portion made of non-magnetic alloy

A timepiece component including a shaft-like portion including at least one pivot about a pivot axis, wherein at least the constituent material of this shaft-like portion is a ceramic or similar non-magnetic type material, the shaft-like portion includes a plurality of recesses evenly arranged or regularly distributed about the pivot axis, and has its centre of inertia on the pivot axis, and the shaft-like portion includes a collar forming its largest diameter with respect to the pivot axis, which collar includes a parting line of the shaft-like portion, which parting line is substantially perpendicular to the pivot axis, the recesses pass right through the collar, and at least one recess contains an injection point for the material.
