Below may be possible causes. Try the following remedies in sequence.
| Cause | Remedies |
|---|---|
| If the surrounding temperature falls below 0°C (32°F) or exceeds 40°C (104°F), the “Charge suspension temperature detection function” will activate and charging will not be possible. | Move to a place with appropriate temperature. | If the “Over discharge detection function” is activated, charging is not possible. If the watch does not work after exposing the dial to direct sunlight for more than one day, it is possible that the rechargeable cell has over discharged. | Consult an authorized service center. |
