Operating the Watch
Basic Timekeeping
Your Nautica Ocean Beach watch is a quartz analog timepiece, providing accurate time display with hour, minute, and second hands. Ensure the crown is fully pushed in for normal operation and water resistance.
Water Resistance
This watch is water-resistant up to 100 meters (10 ATM). This means it is suitable for swimming, snorkeling, and showering. Do not operate the crown or pushers while the watch is wet or submerged in water, as this can compromise the water resistance seal. Always ensure the crown is fully pushed in before exposing the watch to water.
Chronograph and Sub-dials
The watch features multiple sub-dials, which typically function as a chronograph (stopwatch) or other time-related indicators. Specific functions may vary, but common operations include:
- Start/Stop: Press the upper pusher to start and stop the chronograph.
- Reset: Press the lower pusher to reset the chronograph hands to zero after stopping.
- Note: Refer to the specific movement instructions if detailed chronograph operation is required, as this model may feature a world time alarm as indicated on the dial.
Maintenance
Cleaning Your Watch
To maintain the appearance of your watch, regularly wipe the case and strap with a soft, dry cloth. For silicone straps, a mild soap solution and water can be used, followed by thorough rinsing and drying. Avoid harsh chemicals or abrasive materials.
Battery Replacement
The watch is powered by a quartz movement, which requires a battery. When the watch stops or the second hand begins to jump erratically (indicating a low battery), it is time for a replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure the water resistance seal is properly re-established.
Water Resistance Care
The water resistance of your watch is not permanent and may decrease over time due to wear and tear, impacts, or chemical exposure. It is advisable to have the water resistance seals checked periodically, especially if the watch is frequently exposed to water.
Troubleshooting
- Watch not running:
- Check if the crown is fully pushed in.
- The battery may need replacement. Consult a watch technician.
- Time is inaccurate:
- Ensure the crown is fully pushed in after setting the time.
- Exposure to strong magnetic fields can affect quartz accuracy.
- A low battery can also cause inaccurate timekeeping.
- Condensation under crystal:
- This indicates a breach in the water resistance. Immediately take the watch to a qualified technician to prevent further damage.
