IWC Da Vinci 3750

IWC

The IWC Da Vinci Perpetual Calendar Chronograph is a landmark of modern mechanical watchmaking. Created in the mid 1980s, during the revival of haute horlogerie after the quartz crisis, it signaled a renewed confidence in complex, purpose‑driven complications. Central to the watch is the perpetual calendar system developed by now legendary Kurt Klaus. His ingenious construction allows all calendar indications—day, date, month, leap year, and moon phase—to be set entirely via the crown. This unprecedented simplicity transformed the perpetual calendar from an esoteric complication into a practical, user‑friendly instrument. Integrated with a chronograph movement and executed with IWC’s characteristic emphasis on clarity and robustness, the reference 3750 stands today as one of the most influential perpetual calendars of the 20th century, and a defining expression of Kurt Klaus’ enduring technical legacy.
