Your SAPPHERO SO2203 watch is equipped with a chronograph (stopwatch) function. Use the pushers on the side of the watch case to control it:
- **Start/Stop:** Press the top pusher to start the chronograph. Press it again to stop.
- **Reset:** While the chronograph is stopped, press the bottom pusher to reset all chronograph hands to zero.
5.2 Water Resistance (5ATM / 50 Meters)
The watch is water-resistant up to 5 ATM (50 meters), which means it is suitable for daily use, including accidental splashes, rain, and showering. It is NOT suitable for swimming, strenuous exercise in water, shallow diving, or deep diving.

Figure 5.1: Water Resistance Guidelines
Important: Do not operate the crown or pushers while the watch is wet or submerged in water, as this can compromise the water resistance.
5.3 Luminous Hands
The watch features luminous hands, allowing you to read the time clearly even in low-light conditions or at night. The luminous material charges by absorbing light.

6. Maintenance
- **Cleaning:** Regularly wipe your watch with a soft, dry cloth (like the included watch wipe) to remove dust and smudges. For stainless steel parts, a slightly damp cloth can be used, followed by immediate drying.
- **Avoid Chemicals:** Do not expose your watch to harsh chemicals, solvents, or detergents, as these can damage the case, band, or seals.
- **Temperature Extremes:** Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect the movement and water resistance.
- **Magnetic Fields:** Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones) to prevent interference with the quartz movement.
- **Battery Replacement:** When the battery runs out, have it replaced by a qualified watch technician to ensure the watch's integrity and water resistance are maintained.
7. Troubleshooting
If you encounter any issues with your SAPPHERO SO2203 watch, please refer to the following common problems and solutions:

- The battery may be depleted. Contact customer support or a professional watch repair service for battery replacement.
