Water Resistance (100 Meters)
Your Nautica NAI19523G watch is water resistant up to 100 meters (10 ATM). This means it is suitable for swimming, snorkeling, and showering. However, it is not suitable for scuba diving or high-impact water sports.
- Do not operate buttons underwater.
- Avoid exposing the watch to hot water or steam, as this can compromise the water-resistant seals.
- After exposure to saltwater, rinse the watch with fresh water and dry thoroughly.
Maintenance
Cleaning Your Watch
To maintain the appearance of your watch, wipe the case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive cleaners.
Battery Replacement
Your watch is powered by a single 'A' type battery (included). When the display becomes dim or the watch stops functioning, it's time for a battery replacement. It is highly recommended to have the battery replaced by a qualified watch technician to ensure the water resistance is maintained. Improper battery replacement can damage the watch and void the warranty.
Storage
When not in use for extended periods, store your watch in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
- Watch not functioning / Display is blank: The battery may be depleted. Refer to the "Battery Replacement" section.
- Incorrect time/date: Refer to the "Setting the Time and Date" section to re-adjust.
- Water inside the watch: Immediately cease use and take the watch to a professional watch repair service. Do not attempt to open the watch yourself, as this will void the warranty and likely cause further damage.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, check specific model features). If the issue persists, a reset may be required (consult a professional).
