Watch Components

This image displays the watch face with labels indicating the chronograph sub-dials and control buttons. The top pusher is for Start/Pause, the crown adjusts the time, and the bottom pusher is for resetting the chronograph.
- Crown: Used for setting the time and date.
- Pusher A (Top): Controls the start and stop functions of the chronograph.
- Pusher B (Bottom): Resets the chronograph hands to zero.
- Hour, Minute, Second Hands: Indicate the current time.
- Chronograph Hands: Measure elapsed time (seconds, minutes, hours).
- Sub-dials: Typically include a 60-second counter, a 60-minute counter, and a 24-hour indicator.
- Date Window: Displays the current date.
- Tachymeter Bezel: Used for measuring speed over a known distance.
3. Setup
3.1 Setting the Time
- Pull the crown out to Position 2 (the outermost position).
- Rotate the crown to move the hour and minute hands to the desired time.
- Once the time is set, push the crown back into Position 0 (normal operating position).
3.2 Setting the Date
- Pull the crown out to Position 1 (the first click).
- Rotate the crown to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this may interfere with the date change mechanism.
- Once the date is set, push the crown back into Position 0.
4. Operating the Watch
4.1 Chronograph Function
The chronograph allows you to measure elapsed time independently of the main time display.
- To Start: Press Pusher A (top button) to begin timing. The chronograph second hand will start moving.
- To Stop: Press Pusher A again to pause the timing. The chronograph hands will stop, displaying the elapsed time.
- To Resume: Press Pusher A again to continue timing from where it was paused.
- To Reset: While the chronograph is stopped, press Pusher B (bottom button) to reset all chronograph hands to their zero positions.
4.2 Water Resistance

This image illustrates the watch's water resistance. The watch is rated for 100 meters (10 ATM), making it suitable for swimming and showering, but not for deep-sea diving.
Your HaiQin Pagani Design 1779 watch is water-resistant up to 100 meters (10 ATM). This means it is suitable for everyday use, including showering, swimming, and snorkeling. However, it is not recommended for scuba diving or high-impact water sports. Ensure the crown is fully pushed in before any contact with water.
5. Care and Maintenance
5.1 Cleaning
Wipe your watch regularly with a soft, dry cloth to remove dust and dirt. For stubborn marks, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish and seals.
5.2 Battery Replacement
This watch is powered by a Japanese Quartz movement, which uses a battery. When the watch stops or the second hand begins to skip, it indicates that the battery needs replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure the water resistance and proper functioning of the watch are maintained.
5.3 Strap Care
The leather strap should be kept dry and clean. Avoid prolonged exposure to direct sunlight, extreme temperatures, and moisture, which can cause the leather to crack or discolor. Clean the strap with a soft, damp cloth and allow it to air dry naturally.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch not running | Dead battery | Replace battery by a professional. |
| Time is incorrect | Crown not pushed in, or time needs adjustment | Ensure crown is in Position 0. Re-set the time as per Section 3.1. |
| Chronograph hands do not reset to zero | Chronograph was not stopped before resetting, or internal mechanism issue | Ensure chronograph is stopped (Pusher A) before pressing Pusher B. If issue persists, seek professional service. |
| Fogging under crystal | Moisture ingress, temperature change | Avoid extreme temperature changes. If fogging persists, have the watch inspected for water resistance integrity. |
