The internal device that keeps time. The first watches were mechanical, with a balance wheel and mainspring. They had to be wound to keep time. Most watches today use a quartz crystal and a battery for power - they don't require winding. Automatic watches are self-winding, powered by the everyday motion of your wrist.
