Automatic Watches

Automatic watches, also known as self-winding watches, are a type of mechanical watch that does not require a battery to operate. Instead, they are powered by the natural motion of the wearer’s arm. Here’s how they work and some key points to know about them:

How Automatic Watches Work:

1. Rotor Movement: Inside the case of an automatic watch, there is a small semi-circular piece of metal called a rotor. This rotor is connected to the movement of the wearer’s arm.
2. Kinetic Energy: When the wearer moves their arm, the rotor spins around its pivot with the movement. This spinning motion winds the mainspring, which is the energy source of the watch. The mainspring stores the energy that powers the watch.
3. Regulating Mechanism: The energy from the mainspring is released in a controlled manner through a series of gears and springs, regulating the movement of the watch’s hands.
4. Power Reserve: Automatic watches have a power reserve, which indicates how long the watch can run without being worn. If not worn for an extended period, these watches can stop, and the time and date might need to be reset.
