3. Once the correct date is set, push the crown (A) back into position 0.

Note: Avoid setting the date between 9:00 PM and 3:00 AM, as this may interfere with the automatic date change mechanism.

5. Maintenance and Care

5.1 Cleaning Your Watch

• Wipe the watch case and crystal with a soft, dry cloth.
• For the silicone strap, use a mild soap solution and a soft brush, then rinse thoroughly with clean water and dry completely.
• Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish.

5.2 Water Resistance (3ATM / 30 Meters)

Your NAVIFORCE NF8051T watch is water-resistant to 3 ATM (30 meters). This means it is suitable for daily use, splashes, and rain. It is not suitable for showering, bathing, swimming, diving, or any water sports.

• Do not operate the crown or pushers while the watch is wet or submerged in water.
• Ensure the crown is fully pushed in to maintain water resistance.
• If the watch is exposed to saltwater, rinse it with fresh water and dry it thoroughly.

5.3 Battery Replacement

The watch is powered by a quartz battery. When the watch stops or the second hand begins to skip, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.

6. Troubleshooting

• Watch not running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
• Chronograph hands not resetting to zero: Refer to section 4.3 for manual chronograph hand adjustment.
• Date not changing: Ensure the time is set correctly, especially the AM/PM cycle. Avoid setting the date between 9:00 PM and 3:00 AM.
• Condensation inside the watch: This may indicate a loss of water resistance. Avoid further contact with water and seek professional service immediately.
