Initial Setup
Winding the Watch
Your Spinnaker Hull Diver watch is equipped with an automatic movement. This means it is powered by the motion of your wrist. If the watch has stopped or is running low on power, it can be manually wound.
- Unscrew the crown by turning it counter-clockwise until it springs free.
- Turn the crown clockwise approximately 20-30 times. This will provide enough power reserve to start the watch.
- Once wound, the watch will continue to operate as long as it is worn regularly.
Setting the Time and Date
- Unscrew the crown by turning it counter-clockwise until it springs free.
- To set the date: Pull the crown out to the first click position. Rotate the crown either clockwise or counter-clockwise until the correct date is displayed. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- To set the time: Pull the crown out to the second click position. Rotate the crown to move the hour and minute hands to the correct time. Ensure you set the correct AM/PM for the date change mechanism.
- Once the time and date are set, push the crown back in and screw it down tightly by turning it clockwise. This ensures the watch's water resistance.

Operating Your Watch
Using the Unidirectional Bezel
The Hull Diver features a unidirectional rotating bezel, designed for timing events, particularly dives.
- Before starting an event (e.g., a dive), align the zero marker on the bezel with the minute hand.
- As time passes, the minute hand will indicate the elapsed time against the bezel's scale.
- The bezel rotates only counter-clockwise to prevent accidental shortening of the timed interval, which is a critical safety feature for divers.

Water Resistance
Your watch is water resistant up to 20 ATM (200 meters). This rating makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving.
- Always ensure the crown is fully screwed down before exposing the watch to water.
- Do not operate the crown or pushers (if applicable) while the watch is submerged or wet.
- Rinse the watch with fresh water after exposure to saltwater to prevent corrosion.

Care and Maintenance
Proper care will help maintain the appearance and functionality of your Spinnaker watch.
- Cleaning: Wipe the watch case and strap with a soft, damp cloth. For silicone straps, mild soap and water can be used. Ensure the crown is screwed down before cleaning with water.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, strap, or seals.
- Temperature: Avoid exposing the watch to extreme temperatures or sudden temperature changes, which can affect the movement and water resistance.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, MRI machines) as these can affect the accuracy of the mechanical movement.
- Servicing: Mechanical watches benefit from periodic servicing by a qualified watchmaker to ensure long-term accuracy and performance.

Troubleshooting
If you encounter issues with your watch, refer to the following common solutions:
- Watch has stopped: As an automatic watch, it requires motion to power. Manually wind the watch by unscrewing the crown and turning it clockwise 20-30 times. If worn daily, ensure sufficient wrist movement.
- Date not changing at midnight: This indicates the AM/PM setting was incorrect when setting the time. Advance the time by 12 hours.
- Watch running fast or slow: Minor deviations are normal for mechanical watches. If the deviation is significant, the watch may require regulation by a professional watchmaker. Avoid exposing the watch to strong magnetic fields.
- Condensation under crystal: This can indicate a breach in water resistance. Immediately take the watch to a service center to prevent further damage.
