Abstract (en)
[origin: WO2015140168A2] The invention relates to a clock movement comprising at least two regulation units (61, 67) each having an escapement (5, 13) and a controlling member (62, 68), as well as resilient members (44, 46) provided between the torque-sharing device and the escapements. The invention comprises variants with a differential device as well as embodiments in which the regulation units are driven by a common arbour (20). The resilient members can be hairsprings (44, 46). Said members uncouple the regulation units (61, 67) by providing each with a torque that is independent from the pulses of the other.
