A timepiece part, includes a frame having a power source, a housing including a first pivotal movement system and a second pivotal movement system; an escapement set up on a mounting, a first kinematic linkage including a first wheel borne by a first half-shaft from the first pivotal movement system and a second wheel borne by a first half-shaft from the second pivotal movement system, and a second kinematic linkage including a first wheel borne by the second half-shaft from the first pivotal movement system and a second wheel borne by the first or second half-shaft of the second pivotal movement system. One of the wheels borne by the second pivotal movement system is kinematically linked to the power source, and the other wheel borne by the pivotal movement system is stationary relative to the frame. Both wheels borne by the first system are kinematically linked to a differential.

Timepiece part

A timepiece equipped with an alarm mechanism having a striking device and a minute repeater mechanism provided with a striking device. The two striking devices share at least one gong and one hammer. A power source can be locked when the mechanism is at rest and unlocked when the mechanism is in operation. An adjustment system can be used to program the alarm time. A trigger system includes a control member which controls the unlocking of the power source and a cam which is kinematically connected to the movement and performs one revolution every 24 hours. A first striking mechanism is equipped with at least one hammer arranged to strike at least one gong, and a supplemental striking mechanism is equipped with at least one hammer arranged to strike at least one non-resonant object, wherein the power source drives one or the other of these striking mechanisms.

Timepiece comprising an alarm

For a timepiece movement, a striking train mechanism having: at least one resonant element () which can emit at least two sounds of different frequencies, at least two pallets (), and at least two hammers () which are designed to be driven by the pallets () in order to strike the resonant element ().

Timepiece comprising a minute repeater mechanism

A timepiece with an alarm mechanism having: a power source () which is locked when the mechanism is at rest and unlocked when the mechanism is in operation; an adjustment system which can be used to program the alarm time; and a trigger system that includes a control member () which controls the unlocking of the power source and a cam () which is kinematically connected to the movement and performs one revolution every 24 hours. The alarm mechanism also has a first striking train mechanism equipped with at least one hammer () arranged to strike at least one gong (), and a second striking train mechanism equipped with at least one hammer () arranged to strike at least one non-resonant object (), wherein the power source () drives one or the other of the striking train mechanisms.

The invention relates to a control mechanism for a timepiece of the type comprising a frame () defining a reference plane and, secured to this frame:
