Abstract
An escapement mechanism including an escape wheel subjected to a rotational torque and a resonator integral with a pivotally mounted regulating wheel set. The escape wheel includes plural actuators regularly spaced on a periphery thereof, each arranged to cooperate directly with at least a first track of the regulating wheel set. Each actuator includes a first magnetically, or respectively electrically charged, or ferromagnetic or respectively electrostatically conductive surface, to cooperate with the first track which is magnetically, or respectively electrically charged, or ferromagnetic or respectively electrostatically conductive, to repel or attract each first surface of the actuator, and each actuator includes a mechanical stop member to cooperate, in an end-of-travel stop arrangement, with at least a first complementary stop surface included in the regulating wheel set to constitute therewith an autonomous escapement mechanism.
