ESCAPEMENT DEVICE FOR TIMEPIECE COMPONENT

摘要

The invention concerns an escapement device comprising a power source (32) capable of delivering a variable torque based on the angle of rotation of a pinion (330) fixed to said power source, said variable torque having at least a stable position (S) and an unstable position (I). The device further comprises locking means (31) capable of locking power transmission to an oscillator in a stable point of equilibrium (S) and unlocking means (35) capable of unlocking power transmission to said oscillator between a stable point of equilibrium (S) and an unstable point of equilibrium (I).
