How do automatic watches work?

Automatic watches are mechanical timepieces that use a system of gears and springs to keep time and power the watch's functions. Here's a general overview of how an automatic watch works:

  1. The mainspring stores energy. The mainspring is a long, thin strip of metal that is coiled inside the watch's movement (the "engine" of the watch). As the mainspring is wound, it stores energy that will be used to power the watch.

  2. The movement of your wrist winds the mainspring. Automatic watches are powered by the movement of your wrist. As you move your wrist, a small weight called the rotor spins on a pivot, winding the mainspring.

  3. The energy from the mainspring is transmitted to the gear train. The gear train is a series of gears that transmit the energy from the mainspring to the rest of the watch.

  4. The escapement regulates the flow of energy. The escapement is a component of the movement that converts the energy of the mainspring into regular, precise movements of the balance wheel. The balance wheel is a small, oscillating component that helps regulate the flow of time.

  5. The hands are driven by the gear train. The gear train is connected to the hands of the watch, which rotate around the dial to show the time.

Overall, automatic watches are complex mechanical devices that use a series of interconnected components to keep time and power the watch's functions. If you are experiencing any issues with your automatic watch, it is generally a good idea to have it repaired by a professional.
