A luxurious IWC Schaffhausen Portugieser Perpetual Calendar Chronograph, crafted in 18K rose gold with a deep blue sunburst dial. Key highlights: perpetual calendar with day, date, month, leap year, and moon phase complications; chronograph subdials at 12, 6, and 9 o’clock; Arabic numerals and feuille hands in gold-tone; black alligator leather strap with woven texture. The dial features a distinctive 'APS' holographic sticker (likely an authentication or retailer mark), and the case back is sapphire crystal revealing the automatic Calibre 52610 movement. Exceptional craftsmanship with precise finishing—polished bezel, brushed lugs, and refined crown guards. Ideal for formal events, business settings, or collectors seeking horological sophistication. Water resistance to 30m makes it suitable for daily wear but not swimming. The watch exudes timeless elegance and technical mastery, embodying Swiss haute horlogerie tradition since 1868.
