2.3 Strap Adjustment

3. Operating Your Watch
Your Nautica NCT Windrose watch is equipped with several features for daily use.
3.1 Multifunction Dial
The watch features a multifunction quartz movement with three sub-dials on the main face. These sub-dials typically display:
- Day of the Week: Indicates the current day (e.g., MON, TUE).
- Date: Displays the current numerical date.
- 24-Hour Indicator: Shows the time in a 24-hour format, useful for distinguishing AM/PM.
The main hour and minute hands are treated with luminous infill for improved visibility in low-light conditions.
3.2 Water Resistance
This watch is water-resistant to 100 meters (330 feet). This rating means it is suitable for swimming, snorkeling, and recreational diving. However, it is not suitable for scuba diving. Always ensure the crown is fully screwed down before exposing the watch to water to maintain its water resistance.
Important: Do not operate the crown or pushers while the watch is wet or submerged in water.
4. Maintenance
Proper care will help preserve the appearance and functionality of your Nautica watch.
4.1 Cleaning
- Wipe the watch case and strap regularly with a soft, dry cloth to remove dirt and moisture.
- For the silicone strap, a mild soap solution and water can be used, followed by thorough rinsing and drying.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish or seals.
4.2 Water Resistance Care
- Always ensure the screw-down crown and case back are securely tightened after any adjustments or maintenance to maintain water resistance.
- Avoid exposing the watch to extreme temperature changes, which can affect the water-resistant seals.
- It is recommended to have the water resistance checked periodically by a qualified watch technician, especially after several years of use or if the watch has been subjected to impacts.

4.3 Battery Replacement
Your watch is powered by a quartz movement, which requires a battery. When the battery runs low, the watch may stop or the second hand may skip. Battery replacement should be performed by a qualified watch technician to ensure the proper sealing and water resistance are maintained.
5. Troubleshooting
If you encounter issues with your watch, refer to the following common troubleshooting steps.
5.1 Watch Not Running
- Check the Crown: Ensure the crown is fully pushed in and screwed down. If it's pulled out, the watch will not run.
- Battery: The battery may need replacement. Consult a professional watch technician.
5.2 Incorrect Time or Date
- Reset Time/Date: Follow the instructions in Section 2 to reset the time and date.
- Crown Position: Ensure the crown is fully pushed in and screwed down after setting.
5.3 Condensation Under Crystal
