Operating Your Watch
Luminous Hands
The hour and minute hands of your SAPPHERO SO2223 watch are designed with a luminous coating. This feature allows you to read the time easily in low-light conditions or after dark. The hands absorb light during the day and emit a glow in the absence of light.

Water Resistance (3 ATM)
Your watch has a water resistance rating of 3 ATM (30 meters). This means it is designed to withstand splashes, rain, and brief immersion in water, such as washing hands. It is not suitable for swimming, showering, diving, or any activities involving prolonged water exposure or high-pressure water.

Maintenance
Proper care will help maintain the appearance and functionality of your SAPPHERO watch.
Cleaning
- Wipe the watch case and crystal regularly with a soft, dry cloth to remove dust and smudges.
- For the silicone strap, clean with mild soap and water, then rinse thoroughly and dry completely before wearing.

Battery Replacement
As a quartz watch, it is powered by a battery. When the watch stops or the second hand starts skipping, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
Water Resistance Precautions
- Always ensure the crown is fully pushed in after setting the time or date to maintain the watch's water resistance.
- Avoid exposing the watch to extreme temperature changes, as this can affect the water-resistant seals.
Troubleshooting
If you encounter any issues with your watch, please refer to the following common problems and solutions:
- Watch not running:
- Check if the crown is fully pushed in. If it's pulled out, the watch will not run.
- The battery may be depleted. Contact a professional watch repair service for battery replacement. - Date not changing correctly:
- Ensure the time is set correctly, especially the AM/PM cycle. The date typically changes around midnight.
- Avoid setting the date between 9 PM and 3 AM. - Condensation inside the crystal:
- This could indicate a breach in the water-resistant seal. Stop using the watch immediately and seek professional service. - Inaccurate timekeeping:
- For quartz watches, significant inaccuracy might indicate a low battery or a need for servicing.
