Why has my automatic watch stopped, and how do I restart it?

An automatic watch stops when its stored power reserve is depleted, usually after it has not been worn for some time. Gently wind it using the crown if the model supports manual winding, then set the time and wear it so wrist movement can keep it wound. Follow the instructions for your specific movement and never force the crown. If the watch does not restart or stops unusually quickly, contact an authorized watchmaker or Jowissa service.
