1. Setup
1.1 Initial Charging (Eco-Drive)
Your Citizen Eco-Drive watch is powered by light and does not require battery replacement. For initial setup or after prolonged storage in darkness, expose the watch face to a bright light source (natural or artificial) for several hours to ensure a full charge. The watch will typically run for over six months on a full charge, even if stored in the dark.

1.2 Atomic Timekeeping Synchronization
This watch features Atomic Timekeeping, which automatically synchronizes with atomic clocks for precise time. To initiate synchronization, ensure the watch is in an area with good reception, typically near a window, and follow the specific instructions in the detailed manual for your E660 movement (not E650). The watch receives time signals from transmitting towers, ensuring accuracy to one second over millions of years.

1.3 Band Adjustment
The stainless steel bracelet can be adjusted by removing or adding links to achieve a comfortable fit. This process typically requires specialized tools and is best performed by a qualified jeweler or watch technician. Ensure the pins are securely reinserted after adjustment to prevent the band from detaching.

2. Operating Instructions
2.1 Time and Date Functions
Your watch features a perpetual calendar, which automatically adjusts for month length and leap years until 2100. The atomic timekeeping function ensures the time and date are always accurate. For manual time zone adjustments, refer to the detailed E660 movement guide available on the Citizen website.
2.2 Chronograph Function
The chronograph allows for precise timing of events. Use the pushers on the side of the watch case to start, stop, and reset the chronograph. The sub-dials display elapsed time in various increments. Consult the full instruction manual for specific operation details of the chronograph sub-dials.
2.3 Water Resistance
This watch is water resistant to 200 meters (WR 200). This rating makes it suitable for swimming, showering, and recreational diving. Ensure the crown is pushed in completely before exposure to water. Avoid operating pushers underwater.
3. Maintenance
3.1 Charging
To maintain optimal performance, regularly expose your Eco-Drive watch to light. Avoid prolonged storage in dark places. If the watch stops, expose it to bright light until it resumes normal operation. A small LED watch charger can be used for occasional top-ups if natural light is insufficient.
3.2 Cleaning
Clean the watch case and bracelet regularly with a soft, damp cloth. For metal bracelets, a soft brush can be used to remove dirt from between the links. Avoid using harsh chemicals or abrasive materials, as these can damage the finish or sapphire crystal.
3.3 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 extreme temperatures or areas with strong magnetic fields.

4. Troubleshooting
- Watch Not Running: Ensure the watch has been adequately exposed to light for charging. If it has been in darkness for an extended period, a full charge may take several hours.
- Incorrect Time/Date: Verify that the watch has successfully synchronized with the atomic time signal. If not, attempt a manual synchronization as per the detailed E660 movement manual. Check your current time zone setting.
- Loose Band Pins: If the band pins appear loose or fall out, it is recommended to take the watch to a professional watch technician for repair to prevent accidental detachment and loss of the watch.
