3. Date Setting
- Pull the crown (B) out to position 1.
- Rotate the crown clockwise or counter-clockwise to set the date.
- Once the correct date is displayed, push the crown back into position 0.
- Note: Avoid setting the date between 9:00 PM and 3:00 AM, as this may damage the date mechanism. If you need to set the date during this period, first set the time outside this range, adjust the date, then reset the time.
4. Wearing the Watch
Adjust the rubber strap to fit comfortably on your wrist. The buckle clasp should secure the watch without being too tight or too loose, allowing for proper blood circulation and preventing excessive movement.

Operating
1. Basic Timekeeping
Your PAGANI DESIGN PD-1644 watch is a quartz timepiece, known for its accuracy. Once the time and date are set, the watch will maintain precise timekeeping as long as the battery is functional.
2. Chronograph Functions
The watch features a chronograph for measuring elapsed time. Refer to the diagram for pusher locations (A and C).
- Start/Stop: Press pusher A to start the chronograph. Press pusher A again to stop it.
- Reset: While the chronograph is stopped, press pusher C to reset all chronograph hands to their zero positions.
- Split Time (if applicable): This model may not feature a split-time function. For basic elapsed time measurement, use the Start/Stop/Reset sequence.

3. Water Resistance Guidelines (100 Meters / 10 ATM)
Your watch is water-resistant up to 100 meters (10 ATM). This means it is suitable for swimming, snorkeling, and showering. However, it is not suitable for scuba diving or high-impact water sports.
- Ensure the crown and pushers are fully pushed in before any contact with water.
- Do not operate the crown or pushers while the watch is wet or submerged.
- Avoid exposing the watch to hot water, steam, or sudden temperature changes, as this can compromise the water seals.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly with a soft cloth.
Maintenance
1. Cleaning Your Watch
To maintain the appearance of your watch, regularly wipe the case, crystal, and strap with a soft, dry, lint-free cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
2. Battery Replacement
Your quartz watch is powered by a battery. When the battery is low, the second hand may start to jump in 2-second intervals (End-of-Life indicator). Battery life typically ranges from 2 to 3 years.
- Battery replacement should be performed by a qualified watchmaker or service center to ensure proper sealing and maintain water resistance.
- Do not attempt to replace the battery yourself, as this may void your warranty and damage the watch.

3. Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight, extreme temperatures, strong magnetic fields, and chemicals. The original watch box is ideal for storage.
Troubleshooting
- Watch not running:
- Check if the crown is fully pushed in (position 0).
- The battery may be depleted. Refer to the "Battery Replacement" section.
- Incorrect time/date:
- Refer to the "Time Setting" and "Date Setting" sections to re-adjust.
- Chronograph hands not resetting to zero:
- This may indicate a need for calibration or service. Consult a professional watchmaker.
- Condensation under the crystal:
- This indicates a breach in the water resistance. Immediately take the watch to a qualified service center to prevent further damage. Do not attempt to dry it yourself.
