IWC IW3756-03 GST Perpetual Calendar Titanium Black Dial

The IWC IW375603 GST Perpetual Calendar is a testament to IWC's engineering prowess at the turn of the millennium, encapsulating the technical masterwork of their renowned Kurt Klaus perpetual calendar module. Produced circa early 2000s, this reference is especially sought after for its full titanium case, reflecting IWC's commitment to innovative, robust materials in their legendary GST line. The dial, a deep black, provides exceptional legibility for an array of complications including the perpetual calendar, moonphase, and chronograph—features executed without requiring user correction until 2100. Housing an automatic movement based on the robust Valjoux 7750, upgraded with IWC’s proprietary calendar system, this piece is notable for its reliability and ease of use among perpetual calendars. The 43mm case diameter strikes a balance between classic and contemporary proportions, while the substantial 15mm thickness speaks to the movement’s sophistication. Water resistance and precise finishing echo IWC’s sports watch heritage. Collectors prize this model for its merger of technical complexity, modern material execution, and the distinct character only found in the original GST series. The IW3756-03 offers enduring mechanical sophistication in a design language admired by purists and modernists alike. Like New with IWC box and undated papers.
