Charging your watch
For efficient charging
This watch has a solar cell under the dial and stores the power generated by the cell in its built-in rechargeable cell.
The cell is charged by exposing the dial to light such as direct sunlight or fluorescent lamps.
For optimal performance, be sure to:
- Put the watch in a location where the dial is exposed to bright light such as by the window even when it is not used.
- Expose its dial to direct sunlight for 5 or 6 hours at least every month.
- Avoid leaving it in dark places for long periods of time.
!
When you have to store the watch in a dark place for a long time, turn the power save function on manually (manual power save).
For details, see "Power save function".
CAUTION
- Do not charge the watch at a high temperature (about 60°C (140°F) or higher) as doing so may cause movement malfunction.
- If the watch is obscured from light by long sleeves frequently, supplemental charging may be needed to ensure continual operation.
!
The watch stops charging automatically after finishing (overcharging prevention function).
The function prevents damage to performance of the watch and rechargeable cell due to overcharging.
