Setup
1. Initial Winding
Your Thomas Earnshaw ES-8006-0A watch is equipped with an automatic mechanical movement. Before wearing it for the first time or after it has stopped, it needs to be manually wound.
- Ensure the crown is in position 0 (fully pushed in).
- Turn the crown clockwise approximately 20-30 times. This will initiate the movement and build up a power reserve.
- The watch will then continue to wind itself through the motion of your wrist while worn.
2. Setting the Time
- Pull the crown out to position 1 (first click).
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Push the crown back into position 0 to start the watch.
3. Adjusting the Strap
The watch comes with a leather strap. Adjust the buckle to a comfortable fit on your wrist, ensuring it is not too tight or too loose. A proper fit allows the automatic movement to function optimally.

Operating the Watch
Automatic Movement
The ES-8006-0A features an automatic mechanical movement, meaning it is powered by the natural motion of your wrist. When worn regularly (approximately 8-10 hours a day), the watch will maintain its power reserve. If the watch is not worn for an extended period, it may stop and require manual winding as described in the "Setup" section.
Multifunction Display
This watch includes multifunction sub-dials integrated into its skeleton design:
- 24-Hour Sub-dial: Located at the 9 o'clock position, this sub-dial displays the time in a 24-hour format, often synchronized with the main hour hand.
- Day/Night Indicator: Positioned at the 12 o'clock position, this indicator visually distinguishes between day and night hours, typically showing a sun for day and a moon/stars for night.
These functions are typically set automatically when the main time is adjusted. There are no separate pushers for these sub-dials.

Maintenance
Cleaning
- Wipe the watch case and crystal with a soft, dry, lint-free cloth.
- For the leather strap, avoid excessive moisture. If it gets wet, allow it to air dry naturally, away from direct heat.
- Do not use chemical cleaners or abrasive materials, as these can damage the watch's finish.
Water Resistance (50 Meters / 5 ATM)
Your watch is water-resistant to 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, showering, or washing hands. It is not suitable for diving, snorkeling, or prolonged water exposure.
- Important: Ensure the crown is fully pushed in before any contact with water. Do not operate the crown while the watch is wet.
Storage
When not wearing your watch, store it in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields.
Service
Mechanical watches benefit from periodic servicing to ensure optimal performance and longevity. It is recommended to have your watch serviced by a qualified watchmaker every 3-5 years.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is running slow. | Insufficient power reserve. | Manually wind the watch by turning the crown clockwise 20-30 times. Wear the watch regularly to keep it wound. |
| Time is inaccurate. | Watch needs to be set, or has been exposed to a strong magnetic field. | Set the time as described in the "Setup" section. If inaccuracy persists, consult a professional watchmaker for demagnetization. |
| Condensation under the crystal. | Moisture ingress due to improper crown sealing or exceeding water resistance limits. | Immediately take the watch to a qualified watchmaker for inspection and repair to prevent internal damage. |
