2. Setup
2.1 Unboxing and Initial Inspection
Upon receiving your Pagani Design PK-1685 watch, carefully remove it from its packaging. Inspect the watch for any visible damage or missing components. The package should include the watch, a user manual, and a warranty card.
2.2 Initial Winding
Your Pagani Design PK-1685 watch is equipped with a Japanese Seiko NH35 automatic movement. This movement is powered by the motion of your wrist. If the watch has stopped or has not been worn for an extended period, it may require initial manual winding:
- Unscrew the crown counter-clockwise until it pops out to position 1 (winding position).
- Turn the crown clockwise approximately 20-30 times. This will provide enough power reserve to start the watch.
- Push the crown back in and screw it down clockwise firmly to ensure water resistance.
2.3 Setting the Time and Date
To set the time and date on your watch:
- Unscrew the crown counter-clockwise until it pops out to position 1.
- Pull the crown out to position 2 (first click) to set the date. Turn the crown clockwise or counter-clockwise until the correct date is displayed. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement. If the current time falls within this period, adjust the time outside this range first.
- Pull the crown out to position 3 (second click) to set the time. The second hand will stop. Turn the crown to move the hour and minute hands to the desired time. To ensure accuracy, set the time a few minutes ahead and then turn the crown counter-clockwise to move the hands backward to the exact time.
- Once the time and date are set, push the crown back into position 1 and screw it down clockwise firmly against the case to maintain the watch's water resistance.

3. Operating Instructions
3.1 Automatic Movement Operation
The Pagani Design PK-1685 features an automatic mechanical movement. This means it does not require a battery. The watch is powered by the natural motion of your wrist. When worn regularly (approximately 8-10 hours a day), the watch will remain wound. If the watch is not worn for an extended period, it will stop and require manual winding as described in Section 2.2.
3.2 Water Resistance (200 Meters / 20 ATM)
Your watch is water-resistant to 200 meters (20 ATM), making it suitable for professional marine activity and serious surface water sports, but not saturation diving. To maintain water resistance:
- Always ensure the crown is fully screwed down before exposing the watch to water.
- Do not operate the crown or pushers (if any) while the watch is submerged or wet.
- Avoid exposing the watch to extreme temperature changes, such as moving from a hot sauna directly into cold water, as this can compromise seals.
- Rinse the watch with fresh water after exposure to saltwater or chlorine.
3.3 Unidirectional Rotating Bezel
The watch features a unidirectional rotating bezel, which is a common tool for divers to measure elapsed time underwater. To use the bezel:
- Rotate the bezel counter-clockwise to align the zero marker with the minute hand.
- As time passes, the minute hand will indicate the elapsed time against the bezel's markings.
- The unidirectional design prevents accidental rotation in the wrong direction, which could lead to an overestimation of remaining dive time.

4. Maintenance
4.1 Cleaning Your Watch
To keep your watch in optimal condition:
- Wipe the watch case and strap regularly with a soft, dry cloth.
- For stubborn dirt, use a slightly damp cloth with mild soap, then wipe dry. Ensure the crown is screwed down tightly before using any moisture.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish and seals.
4.2 Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box is ideal for storage.
4.3 Periodic Servicing
Like any precision mechanical instrument, your automatic watch requires periodic servicing to ensure its accuracy and longevity. It is recommended to have your watch inspected and serviced by a qualified watchmaker every 3-5 years. This service typically includes cleaning, lubrication, and replacement of worn components and seals.
4.4 Water Resistance Check
The water resistance of your watch is not permanent and may be affected by aging gaskets or accidental impacts. It is advisable to have the water resistance checked annually, especially if the watch is frequently exposed to water.
5. Troubleshooting
5.1 Watch Not Running
- Insufficient Winding: If the watch has stopped, manually wind it by turning the crown clockwise 20-30 times after unscrewing it to position 1.
- Lack of Movement: Ensure you are wearing the watch regularly for sufficient periods (8-10 hours daily) for the automatic movement to self-wind.
- Impact: If the watch has suffered a significant impact, the movement may be damaged. Seek professional service.
5.2 Date Not Changing Correctly
- Incorrect Setting Time: Avoid setting the date between 9 PM and 3 AM. If you need to adjust the date during this period, first set the time outside this range, adjust the date, then reset the time.
- Insufficient Power Reserve: Ensure the watch is adequately wound.
5.3 Condensation Under the Crystal
- Small amounts of condensation that disappear quickly are usually not a concern.
- If large droplets or persistent fogging appear, it indicates a loss of water resistance. Immediately take the watch to a qualified watchmaker for inspection and repair to prevent internal damage.
