Escapement

An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward, advancing the clock's ha

Anchor escapement

In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small pu
Escapement
…an ideal harmonic oscillator is isochronous; its period is independent of its drive force and amplitude of swing. The best escapements such as the deadbeat and the lever approximate this condition. Since the force of the escapement on the oscillator is the source of error in precision timepieces, in general…
