5. Care and Maintenance
5.1 Water Resistance Guidelines
Your SANDA 3133 watch has a water resistance rating of 5ATM (50 meters). This means it is suitable for:
- Water drops
- Rain
- Car wash
- Shower
- Swimming
Important Note: Do NOT press any buttons underwater. Avoid exposure to detergents and other chemicals. If the watch comes into contact with seawater, rinse it immediately with clean water to prevent corrosion.

5.2 Cleaning Your Watch
To keep your watch in good condition, wipe it regularly with a soft, damp cloth. For the TPU strap, mild soap and water can be used, but ensure it is thoroughly rinsed and dried afterwards. Avoid harsh chemicals or abrasive materials that could damage the case or strap.
5.3 Battery Replacement
The watch uses an original Japanese Maxell battery. When the battery runs low, it is recommended to have it replaced by a professional watch technician to ensure the water resistance seal is maintained.
6. Troubleshooting
If you encounter any issues with your SANDA 3133 watch, please refer to the following common problems and solutions:
- Digital Display Blank: Check if the battery needs replacement. If recently replaced, ensure it was installed correctly.
- Analog Hands Not Moving: Ensure the crown is pushed in completely. If the issue persists, the battery may be low or the movement may require service.
- Incorrect Time/Date: Follow the 'Setting Digital Time and Date' instructions in Section 4.1 to reset.
- Buttons Unresponsive: Ensure the watch is not in a locked mode (if applicable, though not a feature of this model). If underwater, buttons will not respond. If dry, a low battery can sometimes affect button responsiveness.
- Condensation Inside Dial: This indicates a breach in the water resistance. Avoid further water exposure and seek professional service immediately.
