THE AUTOMATIC MECHANISM
THE AUTOMATIC MECHANISM
An automatic mechanism, also called an automatic movement, is a type of watch movement that winds automatically thanks to the natural movements of the wearer's wrist. This movement uses a rotor, a free oscillating mass, which moves with the movement of the wrist and winds the watch's mainspring, thereby storing the energy needed to power the watch. Automatic watches are popular for their operation without the need for manual winding and for their traditional aesthetic.
