Mechanism of Self Winding Watches

Self winding watches, also known as automatic watches, operate through a sophisticated mechanical mechanism designed to harness the natural motion of the wearer’s wrist. At the core of this mechanism is a rotor, a semicircular weight that pivots freely inside the watch case. As the wearer moves their arm, the rotor spins, transferring kinetic energy to wind the mainspring, which stores energy and powers the watch.

The mainspring gradually unwinds, releasing energy to drive the gear train and regulate the movement of the watch hands. This process eliminates the need for manual winding, provided the watch is worn regularly. The energy storage capacity typically allows the watch to continue running for a period ranging from 24 to 72 hours when not worn.

Key components involved in the self-winding mechanism include:

  • Rotor: Moves with wrist motion to wind the mainspring.
  • Mainspring: Stores and releases energy to power the watch.
