A timepiece including a repeater mechanism including a barrel, a control mechanism including an actuating member for releasing the repeater mechanism, a release locking device which is activated automatically immediately after releasing the repeater mechanism, the release locking device including a release lever which is moveable between a rest position and a working position, the release lever including a first pin to block the barrel in the rest position and to release the barrel in the working position.

A timepiece pallet fork for a mechanical oscillator including an arbor allowing the timepiece pallet fork to oscillate about a pivot axis, first and second pallets configured to alternatively engage with an escapement wheel when the timepiece pallet fork oscillates, the first pallet being displaceable with respect to the arbor by absorption of energy, the first pallet being displaceable from a first upstream waiting position to a first downstream stopping end position which is offset compared to the first upstream waiting position, and a first arm having an intermediate section including an elastic bend, one end of the arm being fixed with respect to the arbor to form a first fixed end, the intermediate section of the first arm being located between the first fixed end and the first pallet and returning the first pallet towards the first upstream waiting position by the intermediate section being elastically deformable from a first configuration into a second configuration.

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.
