Clockwork
Inner workings of a mechanical clock, pocket watch or wristwatch, or of other mechanisms that work similarly
Clockwork is the inner workings of either clocks and watches (where it is also called the movement) or other mechanical devices that work similarly, using a series of gears driven by a spring or a weight. A clockwork mechanism is often powered by a clockwork motor, consisting of a mainspring, a spiral torsion spring of metal ribbon.

From Wikipedia
Clockwork is the inner workings of either clocks and watches (where it is also called the movement) or other mechanical devices that work similarly, using a series of gears driven by a spring or a weight. A clockwork mechanism is often powered by a clockwork motor, consisting of a mainspring, a spiral torsion spring of metal ribbon. Energy is stored in the mainspring manually by winding it up, turning a key attached to a ratchet which twists the mainspring tighter. Then the force of the mainspring turns the clockwork gears, until the stored energy is used up. The adjectives wind-up and spring-powered refer to mainspring-powered clockwork devices, which include clocks and watches, kitchen timers, music boxes, and wind-up toys.
