This animated video provides a clear explanation of Citizen's Eco-Drive technology. It illustrates how both natural and artificial light are absorbed by the watch's dial, converted into electrical energy, and stored in a rechargeable power cell. This process eliminates the need for battery replacement, ensuring the watch runs continuously as long as it's exposed to light.

4. Initial Setup

4.1. Charging the Watch

Before initial use, ensure your watch is fully charged. Expose the watch dial to a bright light source (natural sunlight is ideal) for several hours. The light level indicator on the dial can help you monitor the charging status. Avoid placing the watch in direct sunlight for extended periods in extremely hot conditions to prevent overheating.

4.2. Setting Time and Date

Pull the crown out to the time setting position.
Rotate the crown to set the desired time.
Push the crown back in to start the watch.
For the perpetual calendar, refer to the detailed instructions in the full user manual for specific adjustment procedures, as it automatically adjusts for month lengths and leap years.

4.3. Band Adjustment

6.2. Water Resistance

Your watch has a water resistance rating of 20 ATM (200 meters), making it suitable for swimming, snorkeling, and recreational diving. Always ensure the crown is pushed in completely before exposing the watch to water.

6.3. Cleaning

Clean your watch regularly with a soft, damp cloth. For metal bands, a soft brush can be used to remove dirt from between the links. Avoid using harsh chemicals or abrasive materials.

6.4. Antimagnetic Properties

The watch is Class 1 antimagnetic, providing protection against magnetic fields encountered in daily life. However, avoid prolonged exposure to strong magnetic sources to maintain optimal accuracy.

7. Troubleshooting

Watch Not Running: Ensure the watch is adequately charged by exposing it to bright light. If it still doesn't run, it may require professional inspection.
Incorrect Time/Date: Refer to Section 4.2 for basic time and date setting. For complex adjustments like the perpetual calendar or time difference, consult the full user manual.
