This IWC Da Vinci Ref. IW3751 is one of the most celebrated perpetual calendar chronographs of its era, powered by the legendary Kurt Klaus perpetual calendar system, entirely mechanically programmed and adjustable via the crown.
The watch features a solid 18k yellow gold case, paired with the classic white dial with Roman numerals, moon phase, chronograph counters, and four-digit year display — a configuration that has become a cornerstone of IWC’s high complications.
This example is offered as a full set, including original box, warranty, and documents.
Please note that the original box is extremely worn due to age, while the watch itself is in perfect technical condition, fully functional and carefully checked.
A historically important and highly collectible IWC perpetual calendar, ideal for collectors seeking a complete set with honest disclosure and excellent mechanical integrity.
