Setup
1. Unboxing and Initial Inspection
Upon receiving your Spinnaker Fleuss watch, carefully remove it from its packaging. Inspect the watch for any visible damage or irregularities. Ensure all components, including the watch and strap, are present.

2. Manual Winding
Your Spinnaker Fleuss watch is equipped with a Miyota 8215 automatic movement. Before wearing it for the first time, or if the watch has stopped due to lack of movement, it is recommended to manually wind it.
- Unscrew the crown counter-clockwise until it pops out to position 1.
- Turn the crown clockwise approximately 20-30 times. This will build up an initial power reserve.
- Push the crown back in and screw it down clockwise to ensure water resistance.
3. Setting Time and Date
- Unscrew the crown and pull it out to position 2 (first click) to set the date. Turn the crown 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.
- Pull the crown out to position 3 (second click) to set the time. The second hand will stop. Turn the crown to move the hour and minute hands to the desired time. To ensure accuracy, synchronize with a reliable time source.
- Once the time and date are set, push the crown back into position 1 and screw it down clockwise firmly against the case to maintain water resistance.
4. Strap Adjustment
The genuine leather strap is designed for comfort and durability. Adjust the buckle to achieve a snug yet comfortable fit on your wrist. Ensure the watch is not too tight, which could restrict circulation, or too loose, which could cause it to move excessively.

Operating
Automatic Movement (Miyota 8215)
Your Spinnaker Fleuss watch is powered by a reliable Miyota 8215 automatic movement. This movement is self-winding, meaning it gains power from the natural motion of your wrist. When fully wound, it offers a power reserve of 41+ hours. If the watch is not worn for an extended period, it will stop and require manual winding or wearing to restart.
Water Resistance (150m / 500ft)
The watch is water resistant to 150 meters (500 feet), making it suitable for swimming, snorkeling, and recreational diving. Always ensure the screw-down crown is fully tightened before any exposure to water. Do not operate the crown or pushers (if applicable) while the watch is submerged or wet, as this can compromise water resistance.
Unidirectional Rotating Bezel
The watch features a unidirectional rotating bezel, which is a crucial tool 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 lengthening of your timed interval.
- Read the elapsed time by observing the minute hand's position against the bezel's markings.

Luminous Display
The hands and hour markers are treated with luminous material, providing visibility in low-light conditions. Exposure to light will charge the luminescence.

Maintenance
Cleaning
To clean your watch, wipe the case and crystal with a soft, damp cloth. For the leather strap, avoid excessive moisture. If it gets wet, allow it to air dry naturally, away from direct heat or sunlight. Do not use harsh chemicals or abrasive materials, as these can damage the watch's finish or strap.
Storage
When not wearing your watch, store it in a cool, dry place, preferably in its original box or a watch case, to protect it from dust, moisture, and impacts.
Water Exposure Care
After exposure to saltwater, rinse the watch thoroughly with fresh water and dry it with a soft cloth. This helps prevent corrosion of the case and bezel.
Professional Service
For optimal performance and to maintain water resistance, it is recommended to have your watch serviced by an authorized watchmaker every 3-5 years. This includes checking the movement, replacing gaskets, and pressure testing.
Troubleshooting
- Watch Not Running: If the watch has stopped, it likely needs to be wound. Manually wind the watch as described in the 'Setup' section, or wear it for several hours to allow the automatic movement to build power.
- Inaccurate Time: Automatic movements may exhibit slight variations in timekeeping. If the watch is consistently running significantly fast or slow, it may require adjustment by a professional watchmaker.
- Condensation Under Crystal: If you notice condensation inside the watch, this indicates a breach in water resistance. Immediately take the watch to a professional watchmaker for inspection and repair to prevent further damage to the movement.
