Pro Diver collection Automatic Watches Automatic watches do not operate on batteries. Automatic watches are made up of about 130 or more parts that work together to tell time. Automatic movements mark the passage of time by a series of gear mechanisms and are wound by the movement of your wrist as you wear it. The gear train then transmits the power to the escapement which distributes the impulses turning the balance wheel.The balance wheel is the time regulating organ of a mechanical watch which vibrates on a spiral hairspring. Lengthening or shortening the balance spring makes the balance wheel go faster or slower to advance or retard the watch. The travel of the balance wheel from one extreme to the other and back again is called oscillation.
