A timepiece movement including, fixed on a same plate, a gear train subjected to a torque in a timepiece movement, and an energy storage to deliver a torque to the gear train for actuating a mechanical mechanism synchronizing rotational speed of the gear train with a resonator having a given natural resonant frequency included in the timepiece movement. The resonator is an annular resonator including a ring disposed around an axis. The ring is arranged to be periodically deformed under an action induced by motion of a drive member, included in this mechanism, and the drive member is driven in a pivoting motion, directly or indirectly, by the gear train. |
