ENERGY STORAGE
SPRINGS. When w inding up a coiled watch spring (spiral torsion spring) the energy is stored and slowly released, providing power to the watch mechanism. This is basically the same mechanism that provides power to wind-up radios, timers and some torches. Spring steel is often used to manufacture the spiral torsion spring.
