Abstract
A timepiece escapement has a balance carrying an eccentric pallet pin periodically and regularly oscillating forward and backward about a balance axis with the pin engaging on each forward oscillation between the teeth of an adjacent escape wheel so as angularly to step this escape wheel. The pin is engageable with the escape wheel through a predetermined lift angle which is equal to less than half of the engagement angle during which the pin is within the orbit of the teeth of the escape wheel and, therefore, prevents this wheel from rotating independently of the balance.
