Setup
- Initial Winding: If the watch has stopped, gently rotate the crown clockwise approximately 30-40 times while it is in the normal operating position (position 1, pushed in against the case). This provides an initial power reserve to start the movement.
- Setting the Time:
- Pull the crown out to position 2 (the outermost position).
- Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into position 1 (normal operating position) to engage the movement.
- Adjusting the Strap: The watch features a brown leather strap with a buckle closure. Adjust the buckle to a comfortable fit on your wrist, ensuring it is secure but not overly tight.
Operating the Watch
The Zeppelin 9666-5 is an automatic mechanical watch. It does not require a battery. The movement is powered by the natural motion of your wrist. When worn regularly, the watch will remain wound and keep accurate time.
- Self-Winding: The internal rotor winds the mainspring as your arm moves. For optimal performance, wear the watch daily for at least 8-10 hours.
- Power Reserve: When fully wound, the watch typically has a power reserve of approximately 36-40 hours. If the watch is not worn for an extended period, it may stop. In this case, manually wind it as described in the 'Initial Winding' section before setting the time.
Maintenance
- Cleaning: Wipe the watch case and crystal with a soft, dry, lint-free cloth regularly to remove dust and fingerprints. For the leather strap, avoid excessive moisture and use a specialized leather cleaner if necessary.
- Water Resistance: This watch is NOT WATER RESISTANT. Avoid all contact with water, including rain, splashes, showering, swimming, or any other moisture exposure. Water damage is not covered under warranty.
- Temperature and Magnetic Fields: Avoid exposing the watch to extreme temperatures (hot or cold) or strong magnetic fields, as these can affect the accuracy of the mechanical movement.
- Storage: When not wearing the watch, store it in a dry, cool place away from direct sunlight.
- Servicing: Mechanical watches benefit from periodic professional servicing (typically every 3-5 years) to ensure continued accuracy and proper functioning.
Troubleshooting
- Watch has stopped:
- Cause: Insufficient power reserve. The watch has not been worn or manually wound enough.
- Solution: Manually wind the watch by rotating the crown clockwise 30-40 times. Then, wear it regularly.
- Watch is losing or gaining time significantly:
- Cause: Exposure to strong magnetic fields, impact, or need for servicing.
- Solution: Keep the watch away from magnetic sources. If the issue persists, professional servicing may be required.
- Crown does not operate smoothly:
- Cause: Dirt or damage.
- Solution: Do not force the crown. Contact customer support or a qualified watchmaker.
