Watch balance wheel. Coloured scanning electron micrograph (SEM). A balance wheel, or balance, is the timekeeping device used in mechanical watches and some clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, the balance spring or hairspring. Magnification: x7, when printed 10 cm wide.
