Useful information: How do battery-less watches work?
Battery-less watches are powered by the movement of the wearer's arm. That movement causes a weight to move back an forth, which sets a micro-generator spinning which produces electrical energy. The electricity is stored in a capacitor (analogous to a battery in a battery-powered watch).
From this point on, the battery-less watch functions as a normal quartz watch does: the electricity is transmitted to an integrated circuit, which keeps the quartz crystal oscillating at 32,768 Hertz. The integrated circuit sends impulses at one-second intervals to the stepping motor, which powers the gear train, which moves the watch's hands. |
