Notes
selfwinding gear from beryllium bronze
springless pawl wheels with hook-levers
With two levers and 15 teeth the pawl wheels are as efficient as a ratchet wheel wit 60 teeth, but significantly more durable, due to big teeth and the missing pressure of a click spring.
Moreover the levers are adjustible to compensate a certain amount of wear.
