Setup and Initial Charge
Your Eco-Drive watch requires light exposure to operate. Upon receiving your watch, it may be in a low-charge state. Follow these steps for initial setup:
- Initial Charging: Expose the watch dial to direct sunlight for at least 6-8 hours, or to bright indoor fluorescent light for approximately 20-30 hours. This ensures a full charge. Avoid placing the watch in extremely hot environments during charging.
- Setting the Time:
- Pull the crown out to the second click position.
- Rotate the crown to set the hour and minute hands. Ensure the AM/PM is correctly set if your watch has a 24-hour indicator.
- Push the crown back into the normal position.
- Setting the Date:
- Pull the crown out to the first click position.
- Rotate the crown to set the date.
- Push the crown back into the normal position.

Operating Your Watch
Your Citizen Eco-Drive watch is designed for continuous operation under normal light exposure. Here are some operational guidelines:
- Regular Light Exposure: For consistent operation, ensure your watch receives regular exposure to light. This can be natural sunlight or artificial indoor lighting.
- Power Reserve: A fully charged Eco-Drive watch can typically run for several months in total darkness. If the watch stops, expose it to light to restart.
- Insufficient Charge Warning: If the second hand starts moving in two-second intervals, it indicates an insufficient charge. Immediately expose the watch to light for charging.

Care and Maintenance
Proper care will help maintain the appearance and function of your Citizen watch:
- Cleaning: Wipe the watch case and crystal with a soft, dry cloth. For the polyurethane strap, use a mild soap solution and rinse thoroughly, then dry completely.
- Water Resistance: While water resistant to 100 meters, avoid operating the crown or pushers underwater. After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
- Temperature Extremes: Avoid exposing your watch to extreme temperatures (above 60°C / 140°F or below -10°C / 14°F) or sudden temperature changes.
- Chemicals: Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the case, strap, or gaskets.
- Storage: When not wearing the watch, store it in a location where it can receive some light to maintain its charge. Avoid storing it in a dark drawer for extended periods.

Troubleshooting
If you encounter any issues with your watch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or second hand moves in 2-second intervals. | Insufficient charge. | Expose the watch to bright light for several hours to fully charge. |
| Date does not change at midnight. | AM/PM setting is incorrect. | Adjust the time by 12 hours. Ensure the date changes around midnight, not noon. |
| Condensation inside the crystal. | Temperature change or moisture ingress. | If condensation persists, contact Citizen customer support for inspection. |
