By shortening the contact surface of the waiting pallet and adding the indirect impulse surface, the impulse-generating escape wheel starts moving before it’s finally released. This significantly shortens the distance that the escape wheel must travel before reaching the impulse pallet. In a traditional construction the escape wheel first has to overcome the recoil and then hurry after the impulse-taking pallet.
