Setup and Initial Configuration
1. Charging the Watch (Eco-Drive)
Your Citizen Eco-Drive watch is powered by light. Before initial use, ensure the watch is fully charged by exposing it to bright light. The charging time varies depending on the light source:
- Direct Sunlight (outdoors): Approximately 11 hours for full charge from a completely discharged state.
- Cloudy Day (outdoors): Approximately 40 hours.
- Fluorescent Lamp (30W, 20 inches): Approximately 130 hours.
Avoid placing the watch in direct sunlight for extended periods in hot environments (e.g., car dashboard) as this may cause damage.
2. Receiving Radio Time Signals
The watch automatically attempts to receive time signals daily. For optimal reception, place the watch near a window or in an open area, away from electronic devices that may cause interference.
- Manual Reception: To manually initiate signal reception, pull the crown out to position 1 (time adjustment position). Press and hold the lower right button (B) for approximately 2 seconds until the second hand points to "RX" or "ON". The watch will then attempt to receive the signal.
- Reception Status: After reception, the second hand will indicate the reception result: "OK" (successful) or "NO" (unsuccessful).
If reception is consistently unsuccessful, try a different location or manually set the time.
3. Setting the Time and Date Manually
If radio signal reception is not possible or desired, you can set the time and date manually.
- Pull the crown out to position 2 (time adjustment position). The second hand will move to the 0-second position.
- Rotate the crown to set the hour and minute hands. Ensure AM/PM is correctly set if applicable (often indicated by the 24-hour sub-dial).
- Push the crown back in to position 0.
- To set the date, pull the crown out to position 1. Rotate the crown to adjust the date.
- Push the crown back in to position 0.
Operating Instructions
1. Using the Chronograph
The chronograph function allows you to measure elapsed time.
- Start: Press the upper right button (A) to start the chronograph. The chronograph second hand will begin moving.
- Stop: Press button (A) again to stop the chronograph. The chronograph hands will display the elapsed time.
- Reset: While the chronograph is stopped, press the lower right button (B) to reset the chronograph hands to their zero positions.
Refer to the sub-dials for minutes and hours measured by the chronograph, if applicable to your model.
2. Tachymeter Scale
The tachymeter scale on the bezel can be used to measure speed or distance based on time. For example, to measure the average speed of a vehicle over a known distance (e.g., 1 kilometer or 1 mile):
- Start the chronograph at the beginning of the distance.
- Stop the chronograph at the end of the distance.
- The position of the chronograph second hand on the tachymeter scale indicates the average speed per hour.
Maintenance and Care
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For metal bracelets, a soft brush with mild soapy water can be used, followed by thorough rinsing and drying.
- Water Resistance: While the watch is water-resistant to 200 meters, avoid operating the crown or pushers when the watch is wet or submerged to prevent water ingress. Rinse the watch with fresh water after exposure to saltwater.
- Temperature: Avoid exposing the watch to extreme temperatures (below 0°C or above 60°C) or sudden temperature changes.
- Chemicals: Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the case, bracelet, or gaskets.
- Magnetic Fields: Avoid strong magnetic fields, as they can affect the accuracy of the watch.
- Servicing: For optimal performance and longevity, it is recommended to have your watch inspected by an authorized Citizen service center every 2-3 years.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently. | Insufficient charge. | Expose the watch to bright light for an extended period to fully charge it. |
| Time is inaccurate or incorrect. | Failed radio signal reception or manual time not set correctly. | Attempt manual signal reception. If unsuccessful, manually set the time and date. Ensure the watch is in an optimal location for signal reception. |
| Chronograph hands do not reset to zero. | Chronograph hands misalignment. | Perform a chronograph hand position correction. (Consult Citizen's official manual for specific steps, as this varies by movement). Generally involves pulling crown to specific position and using pushers to align. |
| Date changes at noon instead of midnight. | AM/PM setting is incorrect. | Manually advance the time by 12 hours. |
If problems persist after attempting these solutions, please contact an authorized Citizen service center.
