IWC 3751 Da Vinci Perpetual Calendar Rattrapante Platinum Gray Dial

Introduced circa 1995 to mark the tenth anniversary of the Da Vinci perpetual calendar chronograph, the reference 3751 Da Vinci Perpetual Calendar Rattrapante in platinum stands as a horological milestone. Crafted in a limited edition of 500 pieces, this model combines a split‑seconds chronograph with a full perpetual calendar, including moon phase and four‑digit year display, powered by IWC’s automatic Calibre 79251. The 39 mm platinum case, approximately 16.5 mm thick, features hinged articulated lugs and a snap‑on caseback, delivering both presence and comfort on the wrist. The gray dial (often appearing silvered in archival references) provides a refined backdrop for the applied indexes and complex subdial layout, enhancing legibility and aesthetic balance. With its dual‑chronograph functionality and perpetual calendar module, this piece represents a rare technical achievement from IWC’s mid‑1990s era, combining complication pedigree with collector appeal. Its limited edition status and association with watchmakers Kurt Klaus and Richard Habring further elevate its desirability among connoisseurs. This reference embodies the pinnacle of IWC’s Da Vinci line of the period, offering both mechanical sophistication and historical significance in a wearable platinum form. Excellent Condition with IWC box and undated papers.
