Setup
Before initial use, ensure the watch is properly set and wound.
1. Initial Winding
As an automatic watch, the Dumas GMT is powered by the motion of your wrist. For initial startup or after a period of inactivity, manually wind the watch by rotating the crown clockwise approximately 30-40 times while it is in the fully pushed-in position (Position 0). This builds up a power reserve.
2. Setting Time and Date
- Unscrew the Crown: Gently unscrew the crown counter-clockwise until it springs out to Position 0.
- Position 1 (Date Adjustment): Pull the crown out to the first click. Rotate the crown clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM to prevent damage to the movement.
- Position 2 (Local Time Adjustment): Pull the crown out to the second click. Rotate the crown to set the local time. The seconds hand will stop, allowing for precise synchronization. Ensure the 24-hour hand (GMT hand) is also correctly aligned with the local time's AM/PM cycle.
- Position 3 (GMT Hand Adjustment): This movement allows for independent adjustment of the GMT hand. While in Position 2, rotate the crown to set the GMT hand to your desired second time zone.
- Secure the Crown: Once settings are complete, push the crown back in and screw it down tightly clockwise to ensure water resistance.

3. Bracelet Adjustment
The stainless steel bracelet can be adjusted by adding or removing links. This process typically requires specialized tools and is best performed by a qualified watchmaker to avoid scratching the bracelet or case. The additional rubber strap can be easily interchanged for different activities or preferences.
Operating the Watch
1. Reading Time and GMT
The watch displays local time using the hour, minute, and seconds hands. The independent GMT hand, often distinguished by its color or shape, indicates a second time zone on a 24-hour scale, typically read against the inner 24-hour track on the dial or the bi-directional bezel.
2. Using the Bi-Directional Bezel
The bi-directional 24-hour bezel can be rotated to align with the GMT hand, allowing for quick calculation of a third time zone. For example, if your GMT hand is set to UTC, you can rotate the bezel to align a specific city's offset with the GMT hand to read its local time directly.
3. Water Resistance (300m / 30 ATM)
The Spinnaker Dumas GMT is water resistant to 300 meters (30 ATM). This makes it suitable for professional marine activity, serious surface water sports, and skin diving. Always ensure the crown is fully screwed down before exposing the watch to water.

Maintenance
Proper care will ensure the longevity and performance of your Spinnaker Dumas GMT watch.
1. Cleaning
After exposure to saltwater, rinse the watch thoroughly with fresh water and dry it with a soft, clean cloth. For general cleaning, use a soft, damp cloth to wipe the case and bracelet. Avoid using harsh chemicals or abrasive materials.
2. Water Resistance Checks
While highly water resistant, the gaskets that ensure water integrity can degrade over time. It is recommended to have your watch's water resistance checked by an authorized service center every 2-3 years, especially if frequently used in water.
3. Storage
When not wearing the watch, store it in a cool, dry place away from direct sunlight and strong magnetic fields. A watch winder can be used to keep the automatic movement running if you do not wear it regularly.
4. Servicing
Automatic movements benefit from periodic servicing, typically every 3-5 years, to ensure optimal performance and accuracy. Contact an authorized Spinnaker service center for professional maintenance.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is running slow. | Insufficient power reserve. | Manually wind the watch by rotating the crown 30-40 times. Wear the watch regularly to keep it wound. |
| Time is inaccurate. | Exposure to strong magnetic fields; need for servicing. | Keep the watch away from strong magnets (e.g., speakers, certain electronics). If inaccuracy persists, professional servicing may be required. |
| Condensation under the crystal. | Water ingress due to unsealed crown or damaged gasket. | Immediately take the watch to an authorized service center. Do not attempt to dry it yourself. This indicates a breach in water resistance. |
