A movement for a timepiece comprising a first energy source (9) intended to sustain the oscillatory movement of a mechanical oscillator comprising a resonator and an escapement, through a finishing gear train that forms, between said first energy source (9) and the escapement a first drive line, said movement further comprising a regulating device (14) intended to control said escapement. The regulating device (14) comprises a stop wheel (16) kinematically connected to said finishing gear train and intended to effect a rotational movement periodically, a control cam (24) driven in rotation and secured to a control wheel (20), a locking device, controlled by said cam (24) for locking said stop wheel (16) and periodically releasing it, and an elastic member (18) intended periodically to store energy from said first energy source (9) and restore it to said oscillator. In addition, said regulating device (14) further comprises transmission means and means of regulating said control wheel (20), said transmission means and said regulating means forming, with the control wheel (20), a second drive line that does not include said finishing gear train, said transmission means being arranged to supply energy to said second drive train, and said regulating means being designed periodically to release said control wheel (20) and allow the transmission means to drive the rotation of said control wheel (20). |
