Operating Instructions
Luminous Features
The watch dial and hands are equipped with luminous material for visibility in low-light conditions. To activate this feature, expose the watch to a strong light source (such as natural sunlight or artificial light) for approximately 30 seconds. The luminous elements will then glow in the dark.

Water Resistance
This watch is rated 3ATM water resistant. This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water (e.g., hand washing). It is not suitable for bathing, swimming, diving, or any activities involving prolonged water exposure or high-pressure water. Always ensure the crown is fully pushed in when the watch is exposed to water.

Maintenance
- Cleaning: Regularly wipe the watch case and strap with a soft, dry, lint-free cloth to remove dust, sweat, and fingerprints. For the stainless steel strap, a slightly damp cloth can be used, followed by a dry cloth.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, strap, or internal components.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect the movement and seals.
- Magnetic Fields: Keep the watch away from strong magnetic fields, as these can interfere with the quartz movement's accuracy.
- Crown Position: Always ensure the crown is fully pushed in after adjusting the time or date to maintain the watch's water resistance.
Troubleshooting
- Watch Not Running:
- Ensure the crown is fully pushed in.
- If the watch is new, check for and remove any plastic battery stopper under the crown.
- The battery may need replacement. Consult a professional watch repair service.
- Date Not Changing Correctly:
- Ensure the time is set correctly, passing midnight to trigger the date change.
- Manually adjust the date by pulling the crown to the first position and rotating it until the correct date is displayed.
- Weak Luminous Glow:
- The luminous material requires exposure to light to charge. Expose the watch to a strong light source (natural or artificial) for at least 30 seconds.
