Mechanical battery
Mechanical watches with automatic winding feature a rotating weight (a rotor) that pivots when the watch moves around — i.e., when you wear it and move your wrist. As it spins, it winds the spring. The term "self-winding" is anachronistic but a more descriptive term you might sometimes see for automatic winding. - Download [PDF]
Automatic vs Mechanical Watches: Is There a Difference?
Mechanical watches with automatic winding feature a rotating weight (a rotor) that pivots when the watch moves around — i.e., when you wear it and move your wrist. As it spins, it winds the spring. The term "self-winding" is anachronistic but a more descriptive term you might sometimes see for automatic winding.
