A high-complication luxury timepiece from IWC Schaffhausen: the Portugieser Perpetual Calendar with Moon Phase. Features a classic white dial with applied Arabic numerals, blued-steel hands, and a distinctive deep-blue moon phase display with stars and two moons. The watch integrates five subdials: day of the week (left), date with leap-year indicator (center bottom), month with year ring (right), power reserve (top right), and small seconds (bottom left). The '2022' window indicates the current year in the perpetual calendar mechanism, which requires no adjustment until 2100. Housed in a polished stainless steel case (~44.2mm), paired with a black alligator leather strap and a screw-down crown. Powered by the in-house Calibre 52610 automatic movement with 7-day power reserve. Exemplifies Swiss horological craftsmanship—elegant, precise, and built for connoisseurs seeking enduring value and technical sophistication. Ideal for formal events, business settings, or discerning collectors who appreciate traditional haute horlogerie.
