3. Setup and Time Setting
Your Meca-Quartz watch combines the accuracy of a quartz movement with the feel of a mechanical chronograph. Follow these steps to set up your watch:
- Unscrew the Crown (if applicable): Some watches feature a screw-down crown for enhanced water resistance. If your crown is screw-down, gently rotate it counter-clockwise until it springs free.
- Set the Time: Pull the crown out to the furthest position (Position 2). Rotate the crown clockwise or counter-clockwise to move the hour and minute hands to the correct time. Push the crown back in to Position 0 (or screw it down if applicable) to start the watch.
- Adjusting the Strap: The watch comes with a genuine leather strap. Adjust the buckle to ensure a comfortable and secure fit on your wrist.

4. Operating the Watch
Your AVI-8 Dambuster watch features a Meca-Quartz movement, which provides precise timekeeping. The main dial displays hours, minutes, and seconds. The sub-dial typically indicates a 24-hour format or other specific functions depending on the movement. Refer to the specific movement's detailed manual for advanced sub-dial operations if present.

5. Maintenance and Care
Proper care will ensure the longevity and performance of your AVI-8 watch:
- Cleaning: Wipe the watch case and crystal with a soft, dry cloth. For the leather strap, avoid excessive moisture and harsh chemicals.
- Water Resistance: This watch has a water resistance rating of up to 5 ATM (50 meters). This means it is suitable for everyday use, light splashes, and short periods of recreational swimming. Do not operate the crown or pushers while the watch is wet or submerged. Avoid hot water, steam, and sudden temperature changes, as these can compromise water seals.
- Battery: As a Meca-Quartz watch, it uses a battery for the quartz timekeeping module. Battery life typically ranges from 2-3 years. When the battery needs replacement, it is recommended to have it done by a qualified watch technician to ensure proper sealing and function.
- Storage: When not in use, store your watch in a cool, dry place, away from direct sunlight and strong magnetic fields.

6. Troubleshooting
If you encounter issues with your watch, consider the following common solutions:
- Watch Not Running:
- Check if the crown is pushed in completely.
- The battery may need replacement. Consult a professional watchmaker.
- Incorrect Time:
- Ensure the crown is fully pushed in after setting the time.
- Re-set the time as described in the "Setup and Time Setting" section.
- Condensation Under Crystal: This may indicate a breach in the water resistance. Avoid further exposure to water and have the watch inspected by a professional immediately.
