Setup
1. Initial Winding
Your Spinnaker Fleuss watch is powered by an automatic Miyota 8215 movement. Before wearing for the first time, or if the watch has stopped, it needs to be manually wound. To do this:
- Unscrew the crown counter-clockwise until it pops out to position 1.
- Turn the crown clockwise approximately 20-30 times. This will initiate power reserve.
- Push the crown back in and screw it down clockwise to ensure water resistance.
The watch will then continue to wind itself through the motion of your wrist while worn.
2. Setting Time and Date
To set the time and date on your watch:
- Unscrew the crown counter-clockwise until it pops out to position 1.
- Pull the crown out to position 2 (first click) to set the date. Turn the crown clockwise or counter-clockwise until the correct date is displayed.
- Pull the crown out further to position 3 (second click) to set the time. Turn the crown to move the hands clockwise until the correct time is displayed. Ensure to account for AM/PM when setting the date.
- Once time and date are set, push the crown back into position 1 and screw it down clockwise firmly to maintain water resistance.

Operating Your Watch
1. Automatic Movement
The Miyota 8215 movement is an automatic mechanical movement. It is powered by the natural motion of your wrist. When fully wound, it has a power reserve of approximately 42 hours. If the watch is not worn for an extended period, it may stop and require manual winding as described in the Setup section.
2. Unidirectional Rotating Bezel
The Spinnaker Fleuss features a unidirectional rotating bezel, designed for dive timing. To use it:
- Align the bezel's zero marker with the minute hand at the start of your dive or timed event.
- The bezel rotates only counter-clockwise, preventing accidental increases in elapsed time.
- Read the elapsed time by noting the position of the minute hand against the bezel's scale.
3. Water Resistance
This watch is water resistant to 150 meters (15 ATM). This rating makes it suitable for swimming, snorkeling, and recreational diving. Always ensure the crown is fully screwed down before exposing the watch to water. Do not operate the crown while the watch is submerged or wet.

Maintenance
1. Cleaning
To maintain the appearance of your watch:
- Wipe the case and crystal with a soft, dry cloth regularly.
- For stainless steel parts, a slightly damp cloth can be used, followed by a dry cloth.
- Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish.
2. Leather Strap Care
The leather strap is susceptible to wear and tear from moisture, sweat, and direct sunlight. To prolong its life:
- Avoid prolonged exposure to water. If it gets wet, dry it gently with a soft cloth and allow it to air dry completely.
- Avoid direct sunlight and extreme temperatures.
- Clean with a specialized leather cleaner if necessary, following product instructions.
3. Professional Service
For optimal performance, it is recommended to have your automatic watch serviced by a qualified watchmaker every 3-5 years. This includes checking the movement, seals, and water resistance.
Troubleshooting
- Watch Not Running: If the watch has stopped, manually wind it by turning the crown clockwise 20-30 times after unscrewing it to position 1. Ensure it is worn regularly to keep the automatic movement powered.
- Inaccurate Time: Automatic movements can vary slightly in accuracy. If your watch is consistently gaining or losing significant time, it may require regulation by a professional watchmaker.
- Date Not Changing: Ensure the time is set correctly, accounting for AM/PM. The date typically changes around midnight. If the date changes at noon, advance the time by 12 hours.
- Water Leakage: If you suspect water has entered the watch, immediately take it to a professional watchmaker for inspection and repair to prevent further damage. Always ensure the crown is fully screwed down before water exposure.
