Definition of the day

Fusee,

A more or less conically shaped part with spiral grooves for winding a chain or a cord connected to the barrel. The fusee regulates the power transferred to the gears. Almost all 16th, 17th and 18th century watches have a fusee. The barrel was connected to the fusee by catgut which was later replaced by a chain around 1640.
