An automatic watch attains energy through the motion of the wearer's wrist. A general automatic watch is composed of more than 70 parts. As a watch runs, the mainspring looses energy. Hence it is necessary to wind a watch in order to store energy that runs the timekeeper.

What supplies energy to an automatic watch?

Rotor. A half circle-shaped metal weight attached to the movement that can swing freely in 360 degrees as the wrist moves. The rotor is connected by a series of gears to the mainspring and as it turns, it winds the mainspring, giving the watch energy.

How does a wrist watch use energy?

A battery sends an electric current to a tiny, tuning-fork-shaped piece of quartz, causing it to oscillate at 32,768 vibrations per second. The watch's circuits reduce that number to one vibration per second, or one hertz, and those pulses are translated into ticks by a tiny electric motor.

How does a watch power itself?

The rotor is usually shaped in a semi-circle and is connected to the mainspring via a series of gears. With the motion of your wrist, the rotor spins on an axle and in doing so, winds the mainspring which in turn powers your watch.

Is it OK to let an automatic watch stop?

It's not bad to let your automatic watch stop. Automatic watches are perfectly safe when stopped – that is to say that the movement doesn't run anymore because the mainspring is fully unwound. Just wind again the next time you want to wear it, and you're good to go. It's not bad for an automatic watch movement to stop.
