Setup and Initial Operation
Your Nautica A15102G watch is equipped with a quartz movement, ensuring accurate timekeeping. Before wearing, you may need to set the time and date.
Setting the Time
- Locate the crown on the right side of the watch case.
- Pull the crown out to the second click position (farthest out). The second hand will stop.
- Rotate the crown clockwise or counter-clockwise to move the hour and minute hands to the correct time. Pay attention to the AM/PM indication if your watch has a 24-hour sub-dial or if setting the date.
- Once the time is set, push the crown back into its normal operating position (first click) to start the watch.
Setting the Date
The watch features a date display. To set the date:
- Pull the crown out to the first click position.
- Rotate the crown to adjust the date. Rotate it until the correct date appears in the date window. Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
- Push the crown back into its normal operating position.

Operating the Chronograph Function
Your Nautica A15102G watch includes a chronograph (stopwatch) function. The watch features three sub-dials and two pushers (buttons) located above and below the crown.
- Start/Stop Pusher (Top Pusher): Press this pusher to start the chronograph. Press it again to stop the chronograph.
- Reset Pusher (Bottom Pusher): After stopping the chronograph, press this pusher to reset all chronograph hands to their zero positions.
- Sub-dials: These typically measure elapsed seconds, minutes, and sometimes hours, depending on the specific movement. Refer to the watch face for specific markings.
Maintenance and Care
Proper care will help maintain the appearance and functionality of your Nautica watch.
Cleaning
Wipe the watch case and strap regularly with a soft, dry cloth. For the silicone strap, a damp cloth with mild soap can be used, followed by thorough drying.
Water Resistance
The Nautica A15102G watch is water-resistant to 100 meters. It is important to ensure the crown is fully pushed in before any contact with water. Avoid operating the pushers or crown while the watch is wet or submerged, as this can compromise the water resistance.
Battery Replacement
The watch is powered by a quartz battery. When the watch stops or the second hand begins to jump erratically (if applicable), it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
Troubleshooting
- Watch Not Running: Check if the crown is fully pushed in. If it is, the battery may need replacement.
- Incorrect Time/Date: Refer to the "Setting the Time" and "Setting the Date" sections to re-adjust. Ensure the crown is fully pushed in after setting.
- Chronograph Hands Not Resetting to Zero: If the chronograph hands do not reset to zero after pressing the reset pusher, consult a qualified watch technician for adjustment.
