7. Care and Maintenance
7.1 Water Resistance
Your NAVIFORCE NF9242 watch has a water resistance rating of 3ATM (30 meters). This means it is suitable for daily use and can withstand splashes, rain, and brief immersion in water, such as hand washing. It is NOT suitable for showering, bathing, swimming, diving, or snorkeling.

Important: Do not operate any buttons or pull out the crown while the watch is wet or submerged in water, as this can compromise the water resistance.
7.2 Cleaning
To clean your watch, wipe it gently with a soft, dry cloth. For the silicone strap, you can use a slightly damp cloth with mild soap, then rinse and dry thoroughly. Avoid using harsh chemicals or abrasive materials.
7.3 Battery Replacement
When the digital display dims or the watch stops functioning, it may be time to replace the battery. It is recommended to have battery replacement performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
7.4 Storage
When not in use, store your watch in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields.
8. Troubleshooting
- Watch not running or digital display is blank:
- The battery may be depleted. Replace the battery with a new one. If the issue persists, consult a watch technician.
- Analog time is incorrect:
- Ensure the crown is fully pushed in. If it's still incorrect, pull out the crown and reset the analog time as per Section 5.1.
- Digital time/date is incorrect:
- Enter the digital setting mode as per Section 5.2 and adjust the time and date.
- Water appears inside the watch:
- This indicates a breach in water resistance. Stop using the watch immediately and take it to a qualified technician for inspection and repair to prevent further damage.
9. User Tips
- To prolong the life of your watch, avoid exposing it to sudden temperature changes or strong impacts.
- While the watch is water-resistant, it's best to remove it before showering or swimming to prevent potential damage from steam or prolonged submersion.
- Regularly check that the crown is fully pushed in to maintain water resistance.
