Setup
Initial Winding
As an automatic mechanical watch, the Pagani Design 1790 does not require a battery. It is powered by the movement of your arm. For the first use, or if the watch has stopped, it needs to be manually wound.
- Ensure the crown is in the fully pushed-in position (position 0).
- Rotate the crown clockwise approximately 20 times. This will initiate the movement and build up a power reserve.
- The watch will then continue to wind itself with your natural arm movements while worn.
Setting the Time
- Gently pull the crown out to position 1 (the outermost position).
- Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into position 0.

Adjusting the Strap
The watch features a comfortable leather strap with a butterfly deployant clasp. To adjust the fit, locate the spring bars connecting the strap to the clasp. These can typically be adjusted by a watchmaker or with a specialized tool to achieve the desired length.
Operating Your Watch
Automatic Winding Mechanism
Your Pagani Design 1790 watch is equipped with an automatic mechanical movement. This means it is powered by the natural motion of your wrist. When worn regularly, the rotor inside the watch moves, winding the mainspring and maintaining the power reserve. If the watch is not worn for an extended period, it may stop and require manual winding as described in the "Initial Winding" section.
Water Resistance (10 Bar / 100 Meters)
The watch is designed to be water-resistant up to 10 Bar (100 meters). This rating indicates suitability for:
- Daily use, such as hand washing.
- Exposure to rain.
- Car washing.
Important Water Resistance Precautions:
- Do NOT press any buttons or operate the crown while the watch is wet or submerged in water.
- Do NOT wear the watch for diving, swimming, showering, or snorkeling.
- Avoid exposing the watch to steam or hot water, such as in a hot shower or sauna, as this can compromise the water seals.
- Excessive exposure to water, especially hot water, can shorten the lifespan of the watch's seals and overall durability.
Maintenance
General Care
- Cleaning: Wipe the watch case and crystal regularly with a soft, dry cloth to remove dust and fingerprints. For the leather strap, avoid excessive moisture and clean with a specialized leather cleaner if necessary.
- Temperature: Avoid exposing the watch to extreme temperatures, both high and low, as this can affect the accuracy of the movement and the integrity of the materials.
- Chemicals: Keep the watch away from harsh chemicals, solvents, and cosmetics, which can damage the case, strap, or seals.
- Magnetic Fields: Automatic mechanical watches can be affected by strong magnetic fields. Keep your watch away from strong magnets (e.g., speakers, refrigerators, certain electronic devices) to maintain accuracy.
- Service: For optimal performance and longevity, it is recommended to have your mechanical watch serviced by a qualified watchmaker every 3-5 years.
Troubleshooting
Watch Not Running or Stopping Frequently
- Insufficient Winding: Ensure the watch has been sufficiently wound. If it has stopped, manually wind the crown approximately 20 times.
- Lack of Movement: If you do not wear the watch daily or have a sedentary lifestyle, the automatic winding mechanism may not receive enough motion to maintain the power reserve. Consider manual winding more frequently or using a watch winder.
Inaccurate Timekeeping
- Magnetic Interference: Exposure to strong magnetic fields can cause the watch to run fast or slow. If you suspect magnetization, a watchmaker can demagnetize it.
- Low Power Reserve: An insufficiently wound watch may not keep accurate time. Ensure it is fully wound.
- Impact: A severe impact can affect the delicate internal components. If accuracy issues persist after winding and demagnetization, professional inspection is recommended.
