摘要:
An escapement for a timepiece includes an escape wheel that rotates about a shaft center and a pallet that oscillates. The escape wheel includes fifteen teeth. The pallet includes an entry pallet jewel and an exit pallet jewel that switch the rotation and stop of the escape wheel and receive torque from the escape wheel by contacting the teeth. The escape wheel and a balance (an impulse pin) apply and receive torque only via the pallet. The pallet includes a third pallet jewel (a torque applying and receiving member) that receives torque from a convex portion of the escape wheel in addition to the entry pallet jewel and the exit pallet jewel.
