About fusee

A fusee is a cone-shaped pulley with a helical groove around it, wound with a cord or chain attached to the mainspring barrel of antique mechanical watches and clocks. It was used from the 15th century to the early 20th century to improve timekeeping by equalizing the uneven pull of the mainspring as it ran down. The watch and clock historian Granville Hugh Baillie stated of the fusee, "Perhaps no problem in mechanics has ever been solved so simply and so perfectly."
