Timepiece escapement mechanism

An escapement mechanism for a timepiece, intended to cooperate with an oscillator arranged to perform oscillations, said mechanism comprising:

• a counting wheel arranged to advance in rotation by steps in function of the oscillations of said oscillator;
• an impulse wheel intended to be kinematically linked with a motive source, said impulse wheel being arranged to be blocked and released periodically under the control of said counting wheel and to supply impulses to said oscillator;
• wherein:
• when said escapement mechanism is operating, said counting wheel is permanently subjected to a torque;
• said counting wheel is arranged to advance in rotation by a half-step of its toothing for each alternation of said oscillator,
• wherein said torque, to which said counting wheel is subjected, is supplied via an elastic element arranged to be wound by said impulse wheel,
• wherein said elastic element forms part of a recharge assembly comprising a recharge assembly wheel kinematically linked with said counting wheel, and
• wherein a first end of said elastic element is fixed to said wheel and a second end of said elastic element is rotationally secured to a recharge wheel arranged to be driven in rotation by a toothing of said impulse wheel.
