Abstract: A timepiece regulator comprising an inertial regulating member which is mounted on a support by an elastic suspension so as to be able to oscillate in translation, along a main direction of translation.

Abstract: 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.
