IW503302. While the original box and papers are not included, the watch was factory serviced by IWC in May 2026, documentation of that service will accompany the watch, and the IWC service warranty remains in effect through December 2026. The watch presents in outstanding condition, with a flawless appearance and exceptional wrist presence. Crafted in 18k rose gold with a stunning silver dial and mounted on a luxurious brown Santoni alligator strap, this watch combines timeless elegance with genuine horological significance. The Portugieser Perpetual Calendar traces its lineage to the legendary perpetual calendar system developed by Kurt Klaus, a masterpiece of mechanical engineering that synchronizes all calendar functions through the crown and automatically accounts for varying month lengths, leap years, and moon phases through the year 2100. Powering the watch is IWC's in-house Caliber 52610, featuring a 7-day power reserve, twin barrels, Pellaton winding system, and beautifully finished movement visible through the sapphire display back. This is not merely a luxury watch—it's a mechanical computer for the wrist. With an original retail price of approximately $55,500, this reference represents one of the most compelling values in modern haute horlogerie. Comparable current Portugieser Perpetual Calendar models continue to command prices in the mid-$50,000 range, making this an extraordinary opportunity to acquire a flagship perpetual calendar from one of Switzerland's most respected manufacturers at a fraction of its original retail price. Elegant, technically sophisticated, and increasingly appreciated by collectors, the IW503302 offers the rare combination of everyday wearability, true mechanical artistry, and enduring collector appeal.\u003c\/div\u003e","brand":"Grailzee","offers":[{"title":"Default Title","offer_id":52343504044164,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/3175\/2836\/files\/main-media-image-1883434.webp?v=1781707690","url":"https:\/\/grailzee.com\/products\/iwc-schaffhausen-iwc-portugieser-iw503302","provider":"Grailzee","version":"1.0","type":"link"}
