The IWC Da Vinci Perpetual Calendar Chronograph, reference IW3750, is one of the most historically significant complicated wristwatches of the modern era. Introduced in 1985, it features the legendary perpetual calendar developed by Kurt Klaus, allowing all calendar functions to be adjusted through the crown - a groundbreaking innovation that helped revive mechanical watchmaking. Housed in solid 18k yellow gold with its matching integrated bracelet, this example offers exceptional wrist presence while weighing an impressive 152 grams, giving it a significant underlying gold value.

The dial is beautifully balanced, with each calendar display thoughtfully arranged for both function and elegance. The moonphase indicator is a standout feature, adding warmth and color while perfectly balanced, creating one of the most harmonious perpetual calendar layouts ever produced.

Named after Leonardo da Vinci, the Da Vinci collection reflects IWC's commitment to combining technical innovation with timeless design. Today, the IW3750 remains a landmark in haute horology, admired for its historical importance, ingenious engineering, and enduring collectability.
