Automatic Movements
Automatic movements aka self-winding mechanical watch movements do not require batteries. These calibers use the movement of your wrist to turn a rotor (osculating weight) that winds a mainspring. The stored energy is released in a controlled process through the escapement and gears that are connected to the hands which tell the time. Automatic watches are designed to not be overwound.
