Setup and Initial Adjustment
1. Setting the Time
- Locate the crown on the right side of the watch case.
- Gently pull the crown out to position 2 (the outermost position). The second hand will stop.
- Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time. Ensure AM/PM is correctly set if your watch has a 24-hour indicator or date changes at midnight.
- Once the time is set, push the crown back into position 0 (normal operating position). The second hand will resume movement.
2. Setting the Date
- Pull the crown out to position 1 (the first click).
- Rotate the crown counter-clockwise to adjust the date. Avoid setting the date between 9:00 PM and 3:00 AM, as this can interfere with the automatic date change mechanism.
- Once the date is set, push the crown back into position 0.
3. Initial Chronograph Reset (if needed)
If the chronograph hands are not aligned to the 12 o'clock position when reset, they may need calibration. Refer to the "Troubleshooting" section for detailed instructions on chronograph hand alignment.

Operating the Chronograph Function
Your Invicta 0839 watch features a chronograph, which is a stopwatch function independent of the main time display.
Chronograph Pushers:
- Pusher A (Top Pusher): Starts and stops the chronograph.
- Pusher B (Bottom Pusher): Resets the chronograph hands to zero.
Using the Chronograph:
- Ensure the main watch crown is in position 0 (pushed in).
- Press Pusher A to start the chronograph. The chronograph second hand will begin to move.
- Press Pusher A again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- To reset the chronograph, press Pusher B. All chronograph hands will return to their zero positions.
Water Resistance
The Invicta 0839 watch is water resistant to 100 meters (330 feet). This rating makes it suitable for recreational swimming and snorkeling. It is not suitable for diving, hot showers, or prolonged submersion at depths beyond its rating. Always ensure the crown is fully pushed in before exposing the watch to water.

Maintenance and Care
Cleaning Your Watch
- For general cleaning, wipe the watch case and strap with a soft, damp cloth.
- For polyurethane straps, mild soap and water can be used, but ensure to rinse thoroughly and dry completely.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish or seals.
Battery Replacement
The watch is powered by a Swiss-quartz movement, which requires a battery. When the battery runs low, the watch may stop or the second hand might skip intervals (End-of-Life indicator). Battery replacement should be performed by a qualified watch technician to ensure the water resistance seal is properly maintained.
Water Resistance Seals
Over time, the gaskets that ensure water resistance can degrade. It is recommended to have the water resistance seals checked by a professional watch service center every 2-3 years, especially if the watch is frequently exposed to water.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch not running | Battery depleted; Crown not pushed in. | Replace battery (professional service recommended); Push crown fully into position 0. |
