Mainspring

2019-10-2 · A mainspring is a spiral torsion spring of metal ribboncommonly spring steelused as a power source in mechanical watches, some clocks, and other clockwork mechanisms. Winding the timepiece, by turning a knob or key, stores energy in the mainspring by twisting the spiral tighter. The force of the mainspring then turns the clock's wheels as it unwinds, until the next winding is needed.
