Setup
1. Initial Charging (Eco-Drive)
Your Eco-Drive watch is powered by light. Upon receiving your watch, expose it to a bright light source (natural or artificial) for several hours to ensure it is fully charged. A full charge can last for months, even in darkness. Avoid storing the watch in dark places for extended periods to prevent it from stopping.

Operating Instructions
1. Chronograph Function
The integrated 1-second chronograph can measure elapsed time up to 50 minutes. Use the pushers on the side of the watch to start, stop, and reset the chronograph. Refer to the detailed manual for specific button operations.
2. Depth Display and Dive Mode
The Aqualand model includes a depth display function, measuring depths up to 50 meters. It features an Auto Start Dive Mode, which automatically activates when submerged, and a Maximum Depth Memory to record your deepest dive. Ensure all crowns are securely screwed down before water exposure.
3. Power Reserve Indicator
The watch is equipped with a power reserve indicator, typically displayed on a sub-dial or via the chronograph second hand, to show the remaining charge level. Keep the watch exposed to light to maintain an optimal power reserve.
4. Rotating Bezel
The stainless steel bezel with blue accents is unidirectional and can be rotated to mark elapsed time, particularly useful for dive timing. Align the bezel's zero marker with the minute hand at the start of an event.

Maintenance
1. Cleaning
Clean your watch regularly with a soft, damp cloth. For the polyurethane strap, mild soap and water can be used. Ensure the watch is completely dry before storing or wearing. Avoid harsh chemicals or abrasive materials.
2. Water Resistance
This watch is water resistant to 200 meters (660 feet), suitable for professional marine activity and serious surface water sports, but not for saturation diving. Always ensure the crown is pushed in and screwed down tightly before any water exposure.
3. Sapphire Crystal Care
The watch features a durable sapphire crystal, known for its scratch resistance. While highly resilient, it is not entirely scratch-proof. Avoid unnecessary impacts or contact with extremely hard surfaces.
4. Luminous Elements
The luminous hands and markers absorb light and glow in low-light conditions, providing enhanced readability. Exposure to bright light will recharge their luminescence.
Troubleshooting
If your watch stops or its functions appear erratic, first ensure it has received sufficient light exposure for charging. If the issue persists, consult the detailed troubleshooting guides available on the official Citizen website. Many common issues can be resolved by following the specific instructions for your movement.
