3. Setup

3.1 Setting the Time and Date

1. Pull out the crown: Gently pull the crown (located on the right side of the watch case, see Figure 2.3) to position 2 (first click) for date adjustment, or position 3 (second click) for time adjustment.
2. Set the Date: If setting the date, turn the crown clockwise or counter-clockwise until the correct date appears in the date window. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
3. Set the Time: If setting the time, turn the crown to move the hour and minute hands. Ensure you set the correct AM/PM by observing the date change (the date will change at midnight).
4. Push in the crown: Once the time and date are set, push the crown back into position 1 (normal position) to start the watch.

3.2 Adjusting the Strap

The watch comes with a leather strap and an additional NATO strap. To adjust the leather strap, simply use the buckle to find a comfortable fit. For the NATO strap, thread it through the spring bars and adjust for a snug fit on your wrist.

4. Operating the Chronograph

Your DUFA DF-9021-0F features a chronograph function for measuring elapsed time.

1. Start: Press the upper pusher (button above the crown, see Figure 2.3) to start the chronograph. The central second hand will begin to move.
2. Stop: Press the upper pusher again to stop the chronograph. The central second hand will stop, indicating the elapsed time.
3. Reset: Press the lower pusher (button below the crown, see Figure 2.3) to reset the chronograph. The central second hand and sub-dials will return to their zero positions.

Note: The sub-dials typically measure minutes and hours for the chronograph function. Refer to the dial markings for specific measurements.

5. Maintenance

5.1 Water Resistance

This watch is designed for "Daily life waterproof" (3 ATM / 30 meters). This means it is resistant to splashes, rain, and brief immersion in water, but it is not suitable for swimming, showering, or diving. Avoid operating the crown or pushers when the watch is wet.

5.2 Cleaning

To maintain the appearance of your watch, wipe the case and crystal with a soft, dry cloth. For the leather strap, avoid prolonged exposure to water and direct sunlight. For the NATO strap, it can be gently hand-washed with mild soap and water, then air-dried.

5.3 Battery Replacement

The watch is powered by a quartz movement and requires a battery. When the second hand begins to skip or the watch stops, it indicates a low battery. Battery replacement should be performed by a qualified watchmaker to ensure proper sealing and function.

5.4 Storage

When not wearing your watch for extended periods, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box (Figure 2.7) is ideal for storage.

6. Troubleshooting

• Watch not running:
  • Check if the crown is fully pushed in (position 1).
  • The battery may be depleted. Refer to Section 5.3 for battery replacement.
• Time is inaccurate:
  • Reset the time as described in Section 3.1.
  • Exposure to strong magnetic fields can affect accuracy. If suspected, consult a watchmaker for demagnetization.
• Chronograph hands do not reset to zero:
  • This may require a chronograph hand alignment procedure, which varies by movement. It is recommended to consult a professional watchmaker for this adjustment.
