These watches notice the movement of your wrist every single time. Its rotor begins to spin with that. The spinning form converts into energy and winds the mainspring automatically.

  • Balanced wheel

It is an internal component that beats in a circular motion—the wheel beats per seconds five to ten times.

  • Dial Train

It is another part of the gear train. This is almost similar to the gear train. According to the hand’s movement, the dial train transfers the power from the balanced wheel into the watch hands. 

  • Jewels
