Abstract (en)
[origin: US7891862B2] The electromechanical escapement device is associated with an electronic circuit having a quartz oscillator and calculation means suitable for calculating the difference between the period of the quartz oscillator and the period of a mechanical oscillator and releasing an escape wheel, normally controlled by said mechanical oscillator, when the difference between said periods is greater than a threshold value.
