A luxury Swiss mechanical timepiece from IWC Schaffhausen, the Portugieser Perpetual Calendar features a classic silver dial with elegant Arabic numerals, moon phase display at 12 o’clock, and four subdials for day, date, month, and leap year indication. The 43.6mm stainless steel case houses the in-house Calibre 52610 automatic movement with 7-day power reserve. Paired with a hand-stitched brown alligator leather strap and polished deployant clasp, it exemplifies haute horlogerie craftsmanship. The clean layout, blued-steel hands, and subtle guilloché textures enhance legibility and sophistication. Ideal for formal business settings, evening events, or discerning collectors seeking timeless elegance. Water resistance to 30m makes it suitable for daily wear but not swimming. The watch is presented by a gloved handler, emphasizing its high-value status and precision engineering.
