3. Setup and Initial Operation
3.1 Setting Time and Date
- Unscrew the Crown: Gently unscrew the crown counter-clockwise until it pops out to position 1.
- Set the Date: Pull the crown out one more click to position 2. Turn the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Set the Time: Pull the crown out to position 3. Turn the crown to set the hour and minute hands. To ensure accuracy, set the time a few minutes ahead and then push the crown back to position 1 when the time signal reaches the desired minute.
- Secure the Crown: Push the crown back to position 1 and screw it in clockwise until it is tight against the case to maintain water resistance.

3.2 Adjusting the Band
The stainless steel band is adjustable by adding or removing links. This process typically requires specialized tools and is best performed by a qualified watch technician to avoid damage to the band or clasp.
4. Operating the Automatic Movement
Your Invicta Pro Diver watch features an automatic (self-winding) mechanical movement. This means it does not require a battery. The watch is powered by the natural motion of your wrist. When worn regularly, the mainspring will remain wound, and the watch will continue to operate.
- Initial Winding: If the watch has stopped, it may need to be manually wound to start. Unscrew the crown to position 1 and turn it clockwise approximately 20-30 times. This will provide enough power for the watch to start running.
- Wearing the Watch: Wear the watch for at least 8-10 hours a day to ensure it remains fully wound.
- Power Reserve: The NH35A movement typically has a power reserve of approximately 41 hours when fully wound. If the watch is not worn for an extended period, it will stop and need to be re-wound.

5. Maintenance and Care
5.1 Water Resistance
This watch is water resistant to 200 meters (660 feet). This rating makes it suitable for professional marine activity, surface water sports, and diving. Always ensure the crown is fully screwed down before exposing the watch to water.
- Do not operate the crown or pushers while the watch is wet or submerged.
- Rinse the watch with fresh water after exposure to salt water or chlorine.
- Avoid exposing the watch to extreme temperature changes, such as moving from a hot sauna to cold water, as this can compromise seals.

5.2 Cleaning
To maintain the appearance of your watch:
- Wipe the case and band with a soft, damp cloth.
- For stainless steel bands, a soft brush and mild soapy water can be used to clean between links. Rinse thoroughly and dry immediately.
- Avoid using harsh chemicals, solvents, or abrasive cleaners.
6. Troubleshooting
- Watch Not Running: If the watch has stopped, it may need to be manually wound (refer to Section 4. Operating the Automatic Movement) or worn for a period to build up power reserve.
- Date Not Changing: Ensure the time is set correctly and the crown is fully pushed in and screwed down. Avoid setting the date during the automatic date change period (9 PM - 3 AM).
- Water Inside Watch: If you notice condensation or water inside the watch, immediately take it to a qualified watch repair center. Do not attempt to open the watch yourself.
