The invention relates to a timepiece part, comprising a frame having a power source, a housing (50) including a first pivotal movement system (52) and a second pivotal movement system (152); - an escapement set up on said mounting (64), a first kinematic linkage including a first wheel (76a) borne by the first half-shaft (54a) from the first pivotal movement system (52) and a second wheel (176a) borne by the first half-shaft (154a) from the second pivotal movement system (152, and a second kinematic linkage including a first wheel (76b) borne by the second half-shaft (54b) from the first pivotal movement system (52) and a second wheel (176b) borne by the first (154a) or the second (154b) half-shaft of the second pivotal movement system (152). To simplify the construction, one of the wheels (176a, 176b) borne by the second pivotal movement system is kinematically linked to the power source, and the other wheel borne by said pivotal movement system is stationary relative to the frame. Both wheels borne by the first pivotal movement system are kinematically linked to an input of a differential (200) set up such as to transmit, to the output thereof, the mean of the rotations received at the inputs thereof. Said output is kinematically linked to the escapement. |
