• Case: Durable stainless steel case.

3. Setup

3.1 Initial Charging

Your Eco-Drive watch is powered by light. Before initial use, ensure the watch is fully charged. Expose the watch dial to bright light (natural sunlight is ideal) for several hours. Avoid placing it in direct sunlight for prolonged periods where temperatures can become extremely high.

• For a full charge from a completely depleted state, expose to direct sunlight for approximately 11 hours, or to fluorescent light (30W, 20cm) for about 40 hours.
• A low charge indicator (if present, usually a two-second interval hand movement) signifies the need for charging.

3.2 Setting Time and Date (Radio Control)

This watch automatically receives time signals to maintain accurate time. Ensure the watch is exposed to an open area, away from electronic interference, for optimal signal reception.

1. Select Home City: Rotate the crown or use the pushers (refer to specific model instructions for exact method) to align the city name on the bezel corresponding to your current time zone with the 12 o'clock position. This sets your home time zone.
2. Automatic Reception: The watch attempts to receive the time signal automatically, typically overnight. Ensure the watch is placed near a window or in an area with good signal reception.
3. Manual Reception: To manually initiate signal reception, press and hold the designated pusher (often the lower right pusher) for a few seconds until the second hand points to "RX" or "OK" on the dial. The reception indicator will show the result:
   • OK: Successful reception.
   • RX: Attempting reception.
   • NO: Reception failed. Try again in a different location.
4. Daylight Saving Time (SMT): Adjust the "SMT" switch on the dial (if applicable, usually via a pusher or crown function) to ON or OFF depending on your region's Daylight Saving Time status.

4. Operating the Watch

4.1 Checking Signal Reception Result

To check the last signal reception result, press the designated pusher (e.g., upper right pusher) briefly. The second hand will point to "OK" (successful), "NO" (failed), or "RX" (in progress) for a few seconds before returning to normal timekeeping.

4.2 Manual Time Adjustment (If Needed)

In areas where radio signals are not available, or if you prefer, you can manually set the time and date.

1. Pull the crown out to the time setting position (usually the second click).
2. Rotate the crown to adjust the hour and minute hands.
3. Push the crown back in to resume timekeeping.

Note: Refer to the full Citizen instruction manual for detailed manual adjustment procedures, especially for date and specific functions.

5. Maintenance

5.1 Cleaning

Regularly wipe the watch case and band with a soft, dry cloth to remove dust and perspiration. For stainless steel bands, a slightly damp cloth can be used, followed by a dry cloth. Avoid using chemical cleaners or abrasive materials.

5.2 Water Resistance

While your watch is designed for daily use, its water resistance level should be noted. Avoid exposing the watch to hot water, steam, or chemicals, as these can compromise the seals. Ensure the crown is pushed in completely before any contact with water.

5.3 Light Exposure

To ensure continuous operation, expose your Eco-Drive watch to light regularly. When not in use, store it in a location where it can receive light, rather than in a dark drawer.

6. Troubleshooting

• Watch has stopped or is running slow:

  This indicates insufficient charge. Expose the watch to bright light for an extended period to fully charge it. After charging, perform a manual signal reception if necessary.

• Time is incorrect after signal reception:

  Check if your home city setting is correct. Ensure the Daylight Saving Time (SMT) setting is appropriate for your region. Try manual signal reception in a different location with better signal.

• Signal reception consistently fails ("NO" indicator):

  Move to an open area, away from buildings, electronic devices, or large metal objects that might interfere with the signal. Try reception during nighttime hours when signal strength is often better.

• Hands are misaligned:

  In rare cases, strong impact or magnetic fields can cause hand misalignment. Refer to the comprehensive Citizen manual for instructions on resetting the reference position of the hands.
