A. Lange & Söhne · Richard Lange "Pour le Mérite"

260.025

A fusée-and-chain transmission in a wristwatch. A chain of more than six hundred parts links the barrel to a cone-shaped fusée, and as the mainspring weakens the chain works along the cone's widening radius, so torque at the escapement stays constant. It is an eighteenth-century marine chronometer solution shrunk to the wrist. "Pour le Mérite" is reserved for Lange references carrying it.
