The GST Perpetual Calendar completes IWC’s successful collection of sports watches for individuals who demand nothing but the very best. The chronograph with the perpetual calendar and the most accurate moon phase display available comes either in a stainless steel case with a rhodium-plated or saumon (left and right) or the most purist of avant-garde materials, ultra-cool titanium (centre). Both versions have the following features in common: aggregate timing from one-eighth of a second to 12 hours, mechanical programming until the year 2499 and a complete four-digit year display (IWC patent). A replacement slide for the 23rd, 24th and 25th centuries is supplied in a sealed glass vial.
