Clockwork
inner workings of a mechanical clock, pocket watch or wristwatch, or of other mechanisms that work similarly From Wikipedia, the free encyclopedia
Clockwork means the inner workings of mechanical machines clocks (where it is also called a "movement". Also other similar mechanisms with a complex series of gears.[1][2][3][4]
A clockwork mechanism usually has a clockwork motor.[5] This has a mainspring, a spiral of metal ribbon. Energy is stored in the mainspring 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. These include clocks and watches, kitchen timers, music boxes, and wind-up toys.
