How do those watches work that charge themselves by motion?

    Basically, there is a pendulum that is set in motion by the user of the watch, simply by going about their daily activities.  This pendulum is connected to a gear, and the gear is connected to a small electric generator.

    Hope this helps!

    Kinetic watches use the motion of the person wearing them to keep itself running.  They have gained in popularity due to their low maintenance characteristics, storing kinetic energy in a capacitor to emit power.  They eliminate the need for watch batteries or winding and most watches possess a sensor to detect inactivity.  One thing to keep in mind is that the capacitor generally needs to be retuned after several years.
