Escapement

Energy from the mainspring is restrained by the escapement to help control the gear train. At the same time the escapement provides further energy to the balance spring where unavoidable losses due to friction are compensated. Modern wristwatches usually contain the pallet escapement which consists of the escape wheel and its pinion.
