2. Product Overview & Button Functions
The SANDA 3133 watch features a robust design with multiple buttons for various functions. Familiarize yourself with the button layout:

3. Setup Instructions
3.1 Setting Digital Time and Date

- Once all settings are correct, press the MODE button again to exit the setting mode.
3.2 Setting Analog Time

5. Maintenance
5.1 Water Resistance

Your SANDA 3133 watch is rated for 50 meters (5 ATM) water resistance. This means it is suitable for:
- Washing hands
- Washing face
- Light rain
- Cold baths
Important: Despite the 50m rating, it is strongly advised NOT to put the watch into water for swimming, showering, or diving, as prolonged exposure or water pressure changes can compromise the seals.
5.2 Cleaning
Wipe the watch case and strap with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or solvents, as these can damage the watch materials.
5.3 Battery Replacement
The watch uses a Maxell Japan battery. When the display dims or the time becomes inaccurate, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
5.4 Acrylic Mirror Care
The watch features an acrylic mirror, which is wear-resistant and scratch-resistant. To maintain clarity, avoid abrasive materials and clean gently as described above.
6. Troubleshooting
- Time Inaccuracy: If the watch is losing or gaining time significantly, the battery may be low, or the movement may require service.
- Display Not Working: Check if the battery is depleted. If the digital display is blank but the analog hands are moving, or vice-versa, there might be an internal issue requiring professional inspection.
- Buttons Unresponsive: Ensure the watch is not in a locked mode (if applicable, though not specified for this model). A low battery can also affect button responsiveness.
- Condensation under Crystal: If condensation appears under the watch crystal, it indicates a breach in water resistance. Seek professional service immediately to prevent further damage.
