6. Water Resistance Guidelines

Figure 4: The watch is designed to withstand water exposure up to 50 meters.

Your PINDOWS PDS-644 watch is rated for 50 meters (5ATM) water resistance. This means it is suitable for:

• Swimming in shallow water.
• Cold baths.
• Handwashing.
• Exposure to rain.

Important Precautions:

• DO NOT press any buttons while the watch is submerged in water. This can compromise the waterproof seals.
• Avoid exposure to hot water, steam, or saunas. Extreme temperature changes can damage the watch's seals.
• After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.

7. Maintenance

• Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying.
• Battery Replacement: The watch uses 1 Lithium Metal battery (included). When the display dims or functions become erratic, it may be time for a battery replacement. It is recommended to have this done by a professional watch technician to ensure water resistance is maintained.
• Storage: Store the watch in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Avoid Chemicals: Do not expose the watch to solvents, detergents, perfumes, or cosmetic sprays, as these can damage the case, strap, or seals.

8. Troubleshooting

• Watch Not Functioning: Check if the battery needs replacement. Ensure no buttons are stuck.
• Incorrect Time Display: Re-set both analog and digital times following the instructions in Section 4.
• Water Inside Watch: If condensation or water appears inside the watch, stop using it immediately and seek professional repair. Water damage is typically not covered under warranty if precautions were not followed.
• Buttons Not Responding: Ensure the watch is not in a locked mode (if applicable, though this model does not specify one). If issues persist, a battery reset (by removing and reinserting the battery) might be necessary, but this should be done by a professional.
