Setup Instructions
Before initial use, ensure your watch is fully charged. Due to the complexity of the perpetual calendar and moon phase functions, detailed setting instructions are best found on the official Citizen website or through the My Citizen app. General steps are outlined below.
1. Initial Charging
Place the watch under a bright light source (natural sunlight is ideal) for several hours. The watch will begin operating once sufficient charge is accumulated. Avoid extreme heat.
2. Setting the Time
- Pull the crown out to the second click position.
- Rotate the crown to set the hour and minute hands. Ensure AM/PM is correctly set if your watch has a 24-hour indicator or if setting the date.
- Push the crown back to the normal position.
3. Setting Date, Day, Month, and Moon Phase
These functions are typically adjusted using the crown in the first click position or via recessed pushers on the watch case. Refer to the specific movement guide for model FD0000-52N on the Citizen website for precise instructions, as incorrect adjustment can damage the movement.
Note: For comprehensive, model-specific setting instructions, including detailed diagrams for adjusting the perpetual calendar and moon phase, please visit the official Citizen Watch website or download the My Citizen app. Search for model FD0000-52N.

Operating Your Eco-Drive Watch
Your Eco-Drive watch is designed to run continuously with proper exposure to light. No winding or battery replacement is necessary under normal conditions.
Light Exposure
- Wear your watch regularly to expose it to light.
- When not wearing, store it in a location where it can receive light, such as near a window, but avoid direct, intense sunlight for prolonged periods to prevent overheating.
- Avoid storing the watch in dark places for extended periods, as this can deplete the power reserve.
Maintenance
Cleaning
Wipe the watch case and bracelet periodically with a soft, dry cloth to remove dirt and perspiration. For water-resistant models, a slightly damp cloth can be used, followed by drying. Avoid using chemical cleaners.
Water Resistance
This watch is designed with a certain level of water resistance. Refer to the markings on the case back for specific depth ratings. Avoid operating the crown or pushers when the watch is wet to prevent water intrusion.
Storage
When storing the watch for extended periods, ensure it is exposed to light periodically to maintain its charge. If the watch stops due to lack of light, simply expose it to light to restart it.
