Setup
1. Setting the Time
- Pull the crown (the knob on the side of the watch) out to the second click position.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Push the crown back in to the normal position to start the watch.
2. Setting the Date
- Pull the crown out to the first click position.
- Turn the crown clockwise to adjust the date. Avoid setting the date between 9:00 PM and 3:00 AM, as this may damage the movement.

Operating Your Watch
Time Reading

Water Resistance
Your Oceanaut OC2715 watch is water resistant up to 20 ATM (200 meters / 660 feet). This makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving. Always ensure the crown is fully pushed in before exposing the watch to water.

Maintenance
Cleaning Your Watch
To maintain the appearance of your watch, wipe the case and strap with a soft, damp cloth. For the silicone strap, mild soap and water can be used. Avoid harsh chemicals or abrasive materials that could damage the finish or crystal.
Water Resistance Precautions
- Do not operate the crown or pushers while the watch is submerged in water or wet.
- Avoid exposing the watch to extreme temperature changes, such as moving from a hot sauna to cold water, as this can compromise seals.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
Battery Replacement
The watch is powered by a Lithium Ion 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 water resistance seal is properly maintained.
Troubleshooting
Watch Not Running
- Ensure the crown is fully pushed in.
- The battery may need replacement. Consult a professional watch technician.
Date Not Changing
- Check if the time is set correctly, especially the AM/PM cycle. The date typically changes around midnight.
- If the issue persists, a professional inspection may be required.
Condensation Inside the Crystal
If you notice condensation inside the watch crystal, this indicates a breach in the water resistance. Immediately take the watch to a qualified service center to prevent further damage to the movement.
