Abstract (en)

[origin: WO2018002773A1] The invention relates to a timepiece escapement comprising a bistable elastic member (2), a winding lever (3) arranged to wind the bistable elastic member (2) during winding phases, and a detent lever (4) arranged to be driven by a detent of said bistable elastic member (2) after each winding phase, in order to transmit an impulse to a regulator. The present timepiece escapement comprises a single escapement wheel (1) for driving the winding lever (3) during the winding phases. Said escapement wheel (1) comprises a winding member (6) arranged to engage with winding elements (11, 12) of said winding lever (3) in a meshing manner such that the winding lever (3) is made to pivot alternately in opposite directions.
