Abstract (en)
[origin: WO2020007619A2] Disclosed is an escapement mechanism (1) for a timepiece, designed to cooperate with an oscillator arranged to carry out oscillations, said mechanism (1) comprising: - a count wheel (7) arranged for step-wise forward rotation depending on the oscillations of the oscillator; - an impulse wheel (11) designed to be kinematically linked to a power source, said impulse wheel (11) being arranged to be periodically blocked and released under the control of the count wheel (7) and to supply impulses to the oscillator, characterized in that: - when said escapement mechanism (1) is operating, the count wheel (7) is continuously subjected to a torque; - and the count wheel (7) is arranged to rotate forward by one half-step of its toothing for every vibration of the oscillator.
