A luxury timepiece from IWC Schaffhausen, the Portugieser Perpetual Calendar features a striking deep blue sunburst dial with applied rose gold Arabic numerals and hands. The 43.2mm 18K rose gold case houses the in-house Calibre 52610 automatic movement, offering a 7-day power reserve and perpetual calendar complication—including day, date, month, leap year, and moon phase indicators—requiring no adjustment until the year 2100. Three subdials display day-of-week (left), date with month ring (right), and moon phase with month/seasonal indicator (bottom). The watch is fitted with a hand-stitched brown alligator leather strap and a sapphire crystal with anti-reflective coating. Crafted in Switzerland with meticulous attention to detail, it exemplifies haute horlogerie elegance and technical sophistication. Ideal for formal events, business settings, or discerning collectors seeking timeless mechanical excellence. The combination of classic Portuguese design language—clean lines, legible layout—and advanced complications makes it both wearable and investment-worthy.
