Setup and Initial Use
1. Unpacking
Carefully remove the watch from its packaging. Inspect the watch for any visible damage. The package should contain:
- DuFa Saphir DF-9030-03 Men's Watch
- User Manual (this document)
- Warranty Card (if applicable)
2. Setting the Time
- Pull the crown (the small knob on the side of the watch case) out to position 2 (the outermost position).
- Turn 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 0 (the innermost position) to start the watch.
3. Setting the Date
- Pull the crown out to position 1 (the first click).
- Turn the crown to adjust the date display. Avoid setting the date between 9 PM and 3 AM, as this may interfere with the automatic date change mechanism.
- Push the crown back into position 0.
4. Winding the Watch (Automatic Movement)
The DuFa Saphir DF-9030-03 features an automatic movement, which means it is powered by the motion of your wrist. If the watch has stopped or is running low on power, you can manually wind it:
- Ensure the crown is in position 0 (pushed in).
- Turn the crown clockwise approximately 20-30 times. This will provide enough power for the watch to start running.
- Wear the watch regularly to keep it wound by your natural arm movements.
Operating the GMT Function
The GMT (Greenwich Mean Time) function allows you to track a second time zone. The watch features a dedicated GMT hand, often indicated by a different color or shape, which completes one rotation every 24 hours.
Setting the GMT Hand
Specific instructions for setting the GMT hand may vary slightly depending on the movement. Generally, it involves a separate crown position or a pusher. For this model, the GMT hand is often linked to the main time setting or has a quick-set function:
- Consult the specific movement instructions if provided separately.
- Often, the GMT hand is set by rotating the main hour hand past 24 hours, or by a specific crown position that moves the GMT hand independently.
- Align the GMT hand with the desired second time zone on the 24-hour scale on the dial.
Maintenance and Care
Water Resistance (3 ATM)
Your DuFa Saphir DF-9030-03 watch has a water resistance rating of 3 ATM (30 meters). This means it is suitable for daily use and can withstand splashes or brief immersion in water, such as washing hands or rain. It is not suitable for showering, bathing, swimming, or diving.
- Do not operate the crown or pushers when the watch is wet.
- Avoid exposing the watch to extreme temperature changes.
Cleaning
To clean your watch:
- Wipe the case and crystal with a soft, dry cloth.
- For the leather strap, avoid prolonged exposure to water, direct sunlight, and harsh chemicals. Clean with a damp cloth and allow to air dry.
Storage
When not wearing your watch for extended periods, store it in a cool, dry place away from direct sunlight and strong magnetic fields. A watch box or pouch is recommended.
Service
For optimal performance, it is recommended to have your automatic watch serviced by a qualified watchmaker every 3-5 years. This includes cleaning, lubrication, and adjustment of the movement.
Troubleshooting
