Maintenance
Water Resistance:

The SKMEI-1335 watch is water-resistant up to 50 meters (5 ATM). This means it is suitable for daily use, hand washing, and showering. However, it is not recommended for diving or prolonged submersion. Avoid pressing buttons underwater, as this can compromise the water seal.
Important: If mist or water droplets appear inside the watch face, contact the manufacturer immediately. Excessive exposure to water, especially hot water or steam, may reduce the watch's lifespan.
Battery Replacement:
The watch is powered by a LR44 battery. When the display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure the water resistance seal is maintained.
Cleaning:
Clean the watch case and strap regularly with a soft, damp cloth. For stainless steel bands, a mild soap solution can be used, followed by thorough rinsing and drying. Avoid using harsh chemicals or abrasive materials.
Troubleshooting
- Display is blank or dim: The battery may be low or depleted. Replace the battery.
- Time is incorrect: Re-set the time following the instructions in the 'Setup' section. Ensure the 12/24 hour format is correctly set.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though not a feature for this model). If issues persist, a battery replacement might resolve it, or contact support.
- Mist inside the watch face: This indicates a breach in the water resistance. Stop using the watch immediately and contact the manufacturer or a service center.
