Setup and Initial Winding
Your Bauhaus Aviation GMT Automatic Watch is powered by a mechanical movement that winds itself with the motion of your wrist. However, for initial setup or after a period of inactivity, manual winding is recommended.
- Unscrew the Crown: The crown is protected by a crown guard. Gently unscrew the crown counter-clockwise until it is free from the case.
- Manual Winding (Position 0): In this position (crown fully pushed in but unscrewed), turn the crown clockwise approximately 30-40 times. This will provide enough power reserve to start the watch.
- Setting the Date (Position 1): Pull the crown out to the first click. Turn the crown clockwise or counter-clockwise to set the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement. If the current time falls within this period, set the date to the previous day and then adjust the time past midnight to advance the date.
- Setting the Time and GMT (Position 2): Pull the crown out to the second click.
- Turn the crown to set the hour and minute hands. The second hand will stop, allowing for precise time setting.
- The central GMT hand (red arrow) is linked to the main hour hand. To set the GMT time, you must advance the main hour hand until the GMT hand indicates the desired 24-hour time.
- Screw Down the Crown: After setting, push the crown back in and screw it down clockwise firmly against the case. This ensures the watch's water resistance.
Important: Always ensure the crown is fully screwed down to maintain water resistance.
Operating Your Watch
Automatic Movement
Your watch is equipped with a Japanese Miyota 9075 automatic movement. This movement is self-winding, meaning it gains power from the natural motion of your arm. When fully wound, the watch has a power reserve of approximately 42 hours. If the watch is not worn for an extended period, it will stop. Simply pick it up, gently shake it side-to-side a few times, or manually wind it as described in the "Setup" section to restart it.
GMT Function
The central red-tipped hand is the GMT (Greenwich Mean Time) hand, which indicates a second time zone in a 24-hour format. This is particularly useful for travelers or those who need to track time in two different locations simultaneously. The GMT hand moves in sync with the main hour hand. To set the GMT time, you adjust the main time until the GMT hand points to the desired 24-hour time on the inner 24-hour scale.
Water Resistance (10 ATM)
Your watch has a water resistance rating of 10 ATM (100 meters / 330 feet), which means it is suitable for swimming, snorkeling, and showering. However, it is not designed for scuba diving. Always ensure the crown is fully screwed down before exposing the watch to water. Avoid operating the crown or pushers (if any) while the watch is wet or submerged.
Maintenance and Care
- Cleaning: Wipe the watch case and crystal regularly with a soft, dry cloth. For titanium bracelets, a soft brush and mild soapy water can be used, followed by thorough rinsing and drying.
- Avoid Extreme Temperatures: Do not expose your watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F) or sudden temperature changes, as this can affect the movement's accuracy and seals.
- Avoid Shocks: While durable, mechanical watches are sensitive to strong impacts. Avoid dropping the watch or subjecting it to severe shocks.
- Chemicals: Avoid contact with solvents, detergents, perfumes, and cosmetic products, as they can damage the case, strap, or seals.
- Magnetism: Keep your watch away from strong magnetic fields (e.g., speakers, refrigerators, MRI machines), as magnetism can affect the accuracy of the mechanical movement. If your watch becomes magnetized, it may run fast or slow and will require demagnetization by a professional.
- Service: For optimal performance and longevity, it is recommended to have your mechanical watch serviced by an authorized service center every 3-5 years. This includes cleaning, lubrication, and checking the seals.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or runs intermittently. | Insufficient power reserve. | Manually wind the watch by unscrewing the crown and turning it clockwise 30-40 times. Wear the watch regularly to keep it wound. |
| Watch runs too fast or too slow. | Magnetization, strong impact, or needs servicing. | Keep away from magnetic fields. If problem persists, consult an authorized service center for demagnetization or regulation. |
| Date does not change or changes at the wrong time. | Incorrect date setting or setting date during restricted hours. | Refer to "Setting the Date" in the Setup section. Avoid setting date between 9 PM and 3 AM. |
| Condensation under the crystal. | Water ingress due to open crown or damaged seal. | Immediately take the watch to an authorized service center. Do not attempt to dry it yourself. Ensure crown is always screwed down. |
