Setup
1. Setting the Time
- Pull the crown (the small knob on the side of the watch) out to the second click position.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time.
- Push the crown back into its normal position to start the watch.
2. Setting the Date
- Pull the crown out to the first click position.
- Turn the crown clockwise to adjust the date. Avoid setting the date between 9:00 PM and 3:00 AM, as this may interfere with the automatic date change mechanism.
- Once the correct date is displayed, push the crown back into its normal position.
3. Adjusting the Mesh Strap
The stainless steel mesh strap features an adjustable buckle clasp for a comfortable fit.
- Use a small tool (like a flat-head screwdriver or a spring bar tool) to lift the clasp lever on the buckle.
- Slide the buckle along the mesh strap to the desired position.
- Press the clasp lever down firmly to secure the buckle in place. Ensure it clicks securely to prevent accidental loosening.

Operating
Basic Timekeeping
Once set, the Japanese quartz movement ensures precise timekeeping. The watch operates continuously until the battery requires replacement.
Water Resistance (3ATM)
Your LIGE LG9903 watch is designed with a 3ATM water resistance rating. This means it is suitable for daily use and can withstand splashes, rain, and brief immersion in water, such as during hand washing.
- Do not use the watch for swimming, diving, or showering with hot water.
- Do not pull out the crown while the watch is submerged in water or wet.
- Exposure to hot water or steam can compromise the watch's water resistance seals.

Maintenance
Cleaning
- Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt.
- For the mesh strap, a slightly damp cloth can be used, followed by immediate drying.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish.
Battery Replacement
The watch is powered by one LR44 battery. When the watch stops or the hands move erratically, it indicates a low battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
Storage
When not in use, store your watch in a cool, dry place, away from direct sunlight and extreme temperatures. Keeping it in its original gift box can provide protection.
Troubleshooting
- Watch Not Running: Check if the crown is fully pushed in. If it is, the battery may need replacement.
- Date Not Changing: Ensure the time is set correctly, especially past midnight. Avoid setting the date between 9:00 PM and 3:00 AM.
- Condensation Inside Dial: This may indicate a breach in water resistance. Avoid further contact with water and seek professional inspection.
