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 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.

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 palladium or platinum with more than 51% of palladium or platinum in the alloy.
