Setup
1. Initial Charging (Eco-Drive)
Your Citizen Eco-Drive watch is powered by light and does not require battery replacement. For optimal performance, ensure the watch is fully charged before initial use.
- Place the watch in direct sunlight or under strong artificial light.
- Avoid placing the watch in direct sunlight for extended periods in high temperatures (e.g., on a car dashboard) as this may damage the watch.
- A full charge typically takes several hours in direct sunlight. The second hand may move in two-second intervals when the power reserve is low, indicating a need for charging.
2. Setting the Time and Date
- Unscrew the crown (if applicable) and pull it out to the time-setting 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 in and screw it down securely to maintain water resistance.
- Refer to the specific movement module instructions for detailed date setting procedures, as these can vary.
Operating Instructions
Basic Timekeeping
Once set, your watch will accurately display the time and date. The Eco-Drive movement ensures continuous operation as long as it is exposed to light.
Luminous Features
The watch features luminous hands and markers (Numerales luminosos, Indicador luminoso) for enhanced visibility in low-light conditions. Exposure to light will charge these elements, allowing them to glow in the dark.
Water Resistance and Diving
This Promaster Aqualand model is designed for diving and is water-resistant up to 200 meters.
- Before diving: Ensure the crown is fully screwed down. Do not operate the crown or pushers underwater.
- After diving: Rinse the watch thoroughly with fresh water to remove salt and sand, then dry it with a soft cloth.
- Regularly check the water resistance with an authorized service center, especially before diving.
Maintenance
Cleaning Your Watch
To maintain the appearance and functionality of your watch:
- Wipe the case and crystal with a soft, dry cloth regularly.
- For the rubber strap, use a mild soap solution and a soft brush, then rinse thoroughly with fresh water and dry.
- Avoid using harsh chemicals or abrasive materials, which can damage the watch's finish.
Eco-Drive Charging
To ensure continuous operation, expose your watch to light regularly. If stored in darkness for extended periods, the watch may stop. A full charge can last for several months in darkness, but regular light exposure is recommended.
Periodic Inspection
It is recommended to have your watch inspected by an authorized Citizen service center every 2-3 years to check gaskets, water resistance, and overall movement condition.
Troubleshooting
- Watch has stopped or is running slow: This usually indicates insufficient charge. Expose the watch to strong light for several hours. If the issue persists after adequate charging, contact a service center.
- Second hand moves in two-second intervals: This is a low power warning. Charge the watch immediately.
- Condensation inside the crystal: This may indicate a loss of water resistance. Stop using the watch immediately and have it inspected by an authorized service center.
- For any other issues or concerns, please contact an authorized Citizen service center for professional assistance. Do not attempt to open or repair the watch yourself.
