Setup
1. Setting the Time
- Pull the crown (middle knob on the right side of the watch) out to the second click position. The second hand will stop.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time.
- Push the crown back in to the normal position. The second hand will resume movement.
2. Setting the Date and Day
- Pull the crown out to the first click position.
- Turn the crown clockwise to set the date.
- Turn the crown counter-clockwise to set the day.
- Once the date and day are set, push the crown back in to the normal position.
Note: To avoid issues, do not set the date or day between 9:00 PM and 3:00 AM, as the watch's internal mechanism is engaged in changing the date/day during this period. If you need to set the date/day during this time, first set the time outside this window, adjust the date/day, then reset the time to the correct current time.
3. Adjusting the Leather Strap
The genuine leather strap is designed for comfort and durability. To adjust the fit, simply insert the buckle pin into the desired hole on the strap. Ensure the watch fits snugly but comfortably on your wrist, allowing for proper blood circulation.
Operating the Chronograph Function
Your DuFa DF-9021-01 watch is equipped with a chronograph (stopwatch) function.
- Start/Stop: Press the upper pusher (button above the crown) to start the chronograph. Press it again to stop the chronograph.
- Reset: While the chronograph is stopped, press the lower pusher (button below the crown) to reset all chronograph hands to their zero positions.
The chronograph features multiple subdials:
- 60-second subdial: Typically located at the 6 o'clock position, this subdial tracks elapsed seconds for the chronograph.
- 60-minute subdial: Typically located at the 9 o'clock position, this subdial tracks elapsed minutes for the chronograph.
- 24-hour subdial: Typically located at the 3 o'clock position, this subdial indicates the time in a 24-hour format, synchronized with the main time display.
Maintenance
Cleaning Your Watch
Regular cleaning will help maintain the appearance of your watch. Use a soft, dry cloth to wipe the case and crystal. For the leather strap, wipe with a slightly damp cloth and allow it to air dry. Avoid using harsh chemicals or abrasive materials.
Water Resistance
Your DuFa DF-9021-01 watch has a water resistance rating of 3 ATM (30 meters / 100 feet). This means it is suitable for daily use and can withstand splashes or brief immersion in water, such as rain or hand washing. It is not suitable for showering, swimming, diving, or any water sports. Do not operate the crown or pushers when the watch is wet.
Battery Replacement
The watch is powered by a quartz movement, which requires a battery. The battery life typically ranges from 2 to 3 years. When the watch stops running, it is likely due to a depleted battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance integrity.
Leather Strap Care
Leather straps are susceptible to wear and tear from moisture, sweat, and direct sunlight. To prolong the life of your strap:
- Avoid prolonged exposure to water.
- Clean with a soft, damp cloth and allow to air dry naturally.
- Avoid direct sunlight and extreme temperatures.
- Consider rotating with another watch or strap to allow the leather to breathe.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch not running | Depleted battery | Replace battery (professional service recommended). |
| Watch running slow/fast | Low battery; exposure to strong magnetic fields; internal mechanism issue. | Replace battery; keep watch away from strong magnets; consult a watch technician. |
| Date/Day not changing | Incorrect setting time (9 PM - 3 AM); internal mechanism issue. | Adjust time outside the restricted window, then set date/day; consult a watch technician. |
| Chronograph hands not resetting to zero | Requires calibration; internal mechanism issue. | Refer to specific movement instructions for chronograph hand calibration (often involves pulling crown to second click and using pushers); consult a watch technician. |
