This escapement is sometimes found in high-quality French clocks; it enables a seconds hand to jump full seconds with a pendulum which beats half-seconds. This is usually achieved by a form of pinwheel escapement, having one pallet hinged to the anchor on to which the pins of the pinwheel drop. When the pendulum swings to the left, the weight at the outer end of the pivoted pallet lifts the coup-perdu pallet clear fo the exit pallet, enabling the pendulum to receive impulse on its swing to the right. The next pin drops on to the coup-perdu pallet, closing it on to the impulse pallet, thus continuing the cycle of operation.
