A timepiece striking mechanism including a mechanism for controlling at least one hammer including a first striking area arranged to strike, in a first direction of travel, a first resonant component on a first striking surface when this at least one hammer moves from a recoiled position to a first impact position, this hammer including, opposite to the first striking area, a second striking area arranged to strike, in a second direction of travel opposite to the first direction of travel, when the hammer recoils from the first impact position to the recoiled position, a second striking surface comprised either in the first resonant component or a second resonant component distinct from the first resonant component.

Repeater mechanism (5), comprising: An hour part (10), which is mobile between a resting position and a reading position; An hour spring (19) which returns the hour part (10) towards its reading position; A chain (40) which is hooked to the hour part (10); A barrel (32) which comprises a shaft (33), a drum (34), a spring (35), a pulley (38) which is mobile in rotation relative to the shaft (33) and on which the chain (40) is hooked, and also a ratchet which is integral in rotation with the barrel shaft (33) and: coupled to the pulley (38) as long as the hour part (10) exerts a traction force on the chain (40); uncoupled from the pulley (38) as soon as this traction force is cancelled out; A pulley spring (38) which is interposed between the ratchet and the pulley (38).

Timepiece with a movement driving an output wheel set, a passing strike or minute repeater mechanism, including a strike drive wheel set including a release ratchet with which cooperates a click for execution of a strike function, a strike uncoupling lever for moving any click away from the strike wheel set, including a first lever carrying the click and its spring, the output wheel set activating a second lever, the pivoting of which causes the first lever to pivot, the striking mechanism includes a torque smoothing jumper, which is returned by a first spring into abutment on the output wheel set, in order to use, when the second lever is not in mesh with the output wheel set, an equivalent torque to that which it uses when meshed with this output wheel set.

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.

Stopping mechanism for a striking mechanism comprising energy storage means including a power reserve transmission wheel set, a strike wheel set comprising a detent ratchet, a main click for the passing strike function and/or a repeater release click, the stopping mechanism includes an uncoupling lever for moving the clicks away from the strike wheel set, by an instantaneous jump of a lever changing the position of the uncoupling lever, when the level of energy of the storage means crosses a predefined threshold, through the cooperation between a finger, driven by the power reserve transmission wheel set, and a jumper returned by a first spring, to bring the finger to bear on a fork of the lever to cause it to pivot abruptly by instantaneously changing the position of a lug with respect to a second spring.

Chiming timepiece comprising a movement and an acoustic indication mechanism with a control mechanism controlling the performance of a chime or tune by setting control lifts in motion that each actuate a hammer arranged to strike a gong, and each control lift is releasable between a released position, in which it is decoupled from the control mechanism, and a resting position, in which it is able to be driven for actuation of the hammer by the control mechanism that is set in motion by the movement, or by a manual actuator, and tune selection devices for the selection of at least one particular chime or tune are controlled by this movement or by a manual selector and control the passage of each control lift from its released position to its resting position or vice versa.
