What is solar charging?
This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.
- This watch uses a special rechargeable (secondary) battery.
- The watch’s battery will not charge if the watch’s temperature is less than approximately -10°C (14°F) or greater than approximately 60°C (140°F).
- Over-discharge will occur if the watch is not charged within approximately three months after it stops operation due to low battery power. Charging may not be possible after over-discharge occurs.
