The lever and chronometer are a few types of escapment found in Gearotic. These include the recoil, Graham, and both the Chrono deadbeat and recoil. An escapement being a mechanical linkage that gives pushes to a wheel keeping it rotating back and forth, while each swing of the wheel allows a gear train to advance a fixed amount depending on your design.
The advantages of the lever is that it is a "detached" escapement. This allows the wheel to swing completely free of the escapement during most of its oscillation except when giving it a short impulse. Due to the "locking" and "draw" action, it is very precise and can be self-starting. The rotation of the escape wheel (deadbeat) is controlled by the pallet which is designed to work as a ratchet. This lever is mounted on a shaft and is free to rotate between two teeth of the deadbeat gear. At rest one of the deadbeat gear teeth will be locked against a pallet and when the escapment wheel rotates, the entrance tooth is locked in place against the pallet.
On chronometer styles, the impulse pin is located within the lever fork and the timing wheel near its center
