Setup
Initial Winding
As an automatic mechanical watch, it does not require a battery. For initial use or after a period of inactivity, manually wind the watch by turning the crown clockwise approximately 30-40 times until the second hand begins to move consistently. The watch will then self-wind with the motion of your wrist during wear.
Setting the Time and Date
- Pull the crown out to the first click position to adjust the date. Turn the crown clockwise or counter-clockwise to set the desired date.
- Pull the crown out to the second click position to adjust the time. Turn the crown to set the hour and minute hands. Ensure the moon phase indicator aligns with the correct time of day (AM/PM).
- Push the crown back in to the normal position to start the watch.

Operating Features
Moon Phase Display
The watch features a unique moon phase display that rotates over time, showcasing the celestial movement. This is an aesthetic feature and does not necessarily correspond to the actual astronomical moon phase.
Luminous Display
The dial incorporates a special luminous design, allowing the stars and moon phase elements to glow in low-light conditions after being exposed to light. This enhances readability and visual appeal in the dark.

Automatic Movement
The watch is powered by a high-quality mechanical movement that is self-winding. It harnesses the natural motion of your arm to keep accurate time. Regular wear ensures continuous operation without manual winding.

Maintenance
Water Resistance
This watch is water-resistant up to 30 meters (3ATM), suitable for daily use such as hand washing or light rain. It is not recommended for swimming, diving, or showering, as prolonged water exposure or high-pressure water jets can damage the watch.

Cleaning and Care
- Wipe the watch case and crystal with a soft, dry cloth regularly to remove dust and fingerprints.
- For the leather strap, avoid prolonged exposure to direct sunlight, extreme temperatures, and moisture to prevent cracking or discoloration. Clean with a damp cloth and mild soap if necessary, then air dry completely.
- Avoid exposing the watch to strong magnetic fields, as this can affect the accuracy of the mechanical movement.
Troubleshooting
Watch Not Keeping Time / Stopping
- Insufficient Winding: If the watch has not been worn for a while, manually wind it by turning the crown clockwise 30-40 times. Ensure you wear the watch regularly for sufficient self-winding.
- Magnetic Interference: Keep the watch away from strong magnetic sources (e.g., speakers, refrigerators, mobile phones) which can magnetize the movement and affect accuracy. If magnetized, professional demagnetization may be required.
Date Not Changing Correctly
- Ensure the time is set correctly, especially the AM/PM cycle. The date typically changes around midnight. Avoid adjusting the date between 9 PM and 3 AM, as this can damage the date mechanism.
