2. Initial Setup
2.1. Unboxing and 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 and in good condition.
2.2. Winding the Watch
As an automatic watch, the Fleuss is powered by the motion of your wrist. However, for initial setup or if the watch has stopped due to lack of wear, it can be manually wound:
- Ensure the crown is in position 1 (fully pushed in, against the case).
- Turn the crown clockwise approximately 20-30 times. This will provide enough power reserve to start the watch.
- The watch will also wind automatically as you wear it throughout the day.
2.3. Setting Time and Date
To set the time and date on your Spinnaker Fleuss watch:
- Pull the crown to position 3: Gently pull the crown out to the furthest position. The second hand will stop, allowing for precise time setting.
- Set the time: Turn the crown clockwise or counter-clockwise to set the hour and minute hands. To avoid damaging the movement, it is recommended to set the time past 12 AM/PM to ensure the date changes correctly.
- Push the crown to position 2: Push the crown in one click to the middle position.
- Set the date: Turn the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this is when the date change mechanism is engaged and could be damaged.
- Push the crown to position 1: Once the time and date are set, push the crown fully back into position 1 (against the case) and screw it down tightly to ensure water resistance.

2.4. Strap Adjustment
The genuine leather strap is designed for comfort and durability. If the strap is too tight or too loose, adjust the buckle to the appropriate hole for a comfortable fit. Ensure the watch is snug but not constricting on your wrist.
3. Operating Your Spinnaker Fleuss Watch
3.1. Automatic Movement
Your Spinnaker Fleuss watch is equipped with an automatic mechanical movement. This means it is powered by the natural motion of your wrist. When worn regularly, the rotor inside the watch winds the mainspring, providing power. If the watch is not worn for an extended period (typically 40 hours for a full power reserve), it will stop. Simply wind it manually as described in Section 2.2 or wear it to restart the movement.
3.2. Water Resistance
The Spinnaker Fleuss watch has a water resistance rating of 150 meters (500 feet). This makes it suitable for swimming, snorkeling, and recreational diving. However, it is crucial to ensure the crown is fully screwed down before any contact with water. Do not operate the crown or pushers (if applicable) while the watch is submerged or wet, as this can compromise the water resistance.

4. Care and Maintenance
4.1. Cleaning
To maintain the appearance of your watch, wipe the case and crystal with a soft, lint-free cloth. For the leather strap, avoid excessive moisture and harsh chemicals. If the watch comes into contact with saltwater, rinse it gently with fresh water and dry thoroughly with a soft cloth.
4.2. Strap Care
The genuine leather strap will naturally develop a unique patina over time. To prolong its life, avoid prolonged exposure to direct sunlight, extreme temperatures, and excessive moisture. If the strap becomes wet, allow it to air dry naturally, away from direct heat.
4.3. 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 scratches.
4.4. Servicing
Mechanical watches benefit from periodic servicing to ensure optimal performance and longevity. It is recommended to have your Spinnaker watch serviced by an authorized watchmaker every 3-5 years.
5. Troubleshooting
Below are common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch not running | Insufficient power reserve (not worn or wound enough). | Manually wind the watch by turning the crown 20-30 times, then wear it regularly. |
| Time inaccuracy | Watch needs regulation or servicing; exposed to strong magnetic fields. | Ensure the watch is fully wound. If inaccuracy persists, consult an authorized service center. Keep away from strong magnets. |
| Condensation under crystal | Temperature change or water resistance compromised. | If minor, it may dissipate. If persistent or large droplets appear, immediately take the watch to an authorized service center to prevent damage. |
