This IWC Schaffhausen Portugieser Perpetual Calendar is a high-complication luxury timepiece featuring a clean white dial with rose gold-toned Arabic numerals and hands, housed in a polished stainless steel case (42.3mm). The dial displays multiple astronomical and calendar functions: moon phase at 12 o’clock with a golden moon and stars; day-of-week subdial at 9 o’clock; date window at 6 o’clock showing '20|23'; month/leap year indicator at 3 o’clock; and a retrograde date hand with 31-day scale. A distinctive sapphire crystal seal with 'CH8' hologram (likely a retailer or distributor mark) is affixed near 7 o’clock. Powered by the in-house Caliber 52610 automatic movement with 7-day power reserve, it features a black alligator leather strap with crocodile texture and deployant clasp. The watch exemplifies Swiss horological craftsmanship—elegant, precise, and built for discerning collectors. Ideal for formal business settings, gala events, or sophisticated daily wear where understated luxury is valued. Water resistance is modest (~30m), emphasizing its dress-watch nature over sport utility.
