Collectors prioritize this reference for its technical durability and the caliber 8541B movement, which features the Pellaton winding system and a shock-absorbing rubber mount. The stainless steel case measures 36mm and was designed by Gérald Genta, characterized by a C-shape profile and integrated lugs. Dials typically feature sunburst finishes or matte textures with applied baton indices and a date window at three o'clock. Due to its high production volume relative to other vintage IWC models, it remains accessible, with secondary market prices generally ranging from $2,500 to $4,500 depending on condition and the presence of the original Gay Frères steel bracelet. A notable variant is the \"blue sunburst\" dial, which often commands a premium at auction over the standard silver or champagne configurations."}, "listing_stats": {"count": 8, "median": 6825.0, "low": 4500.0, "high": 15900.0, "brands": 1, "merchants": 3}, "listings": [{"id": "h_8695738171571", "title": "IWC IWC Pilot’s Chronograph C.03 (Pre-owned)", "brand": "IWC", "model": "IWC Pilot’s Chronograph C.03 (Pre-owned)", "reference": "—", "price_usd": 6050.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 41.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "collective-horology", "merchant_name": "Collective Horology", "image_url": "https://cdn.shopify.com/s/files/1/0559/0623/8643/files/P9176723-2.jpg?v=1789676341", "detail_url": "https://mostexpensivewatches.net/listing/h_8695738171571", "buy_url": "https://mostexpensivewatches.net/out/h_8695738171571", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8695738171571/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8695738171571/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_8695738171571/via/farfetch"}], "available": true}, {"id": "h_16138241311065", "title": "IWC IWC Yacht club II Jumbo Automatic Black dial ref 3212", "brand": "IWC", "model": "IWC Yacht club II Jumbo Automatic Black dial ref 3212", "reference": "3212", "price_usd": 15900.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-3506IWCYachtclub2Jumbo_0010_1x1_b97d9329-26bd-4bdd-9987-ebe9c36691eb.jpg?v=1772183211", "detail_url": "https://mostexpensivewatches.net/listing/h_16138241311065", "buy_url": "https://mostexpensivewatches.net/out/h_16138241311065", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16138241311065/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16138241311065/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_16138241311065/via/farfetch"}], "available": false}, {"id": "h_8049503994035", "title": "IWC IWC Pilot's Watch Chronograph 41 TOP GUN Ceratanium IW388106 (Pre-owned)", "brand": "IWC", "model": "IWC Pilot's Watch Chronograph 41 TOP GUN Ceratanium IW388106 (Pre-owned)", "reference": "—", "price_usd": 9750.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "collective-horology", "merchant_name": "Collective Horology", "image_url": "https://cdn.shopify.com/s/files/1/0559/0623/8643/files/IMG_2055.jpg?v=1736883349", "detail_url": "https://mostexpensivewatches.net/listing/h_8049503994035", "buy_url": "https://mostexpensivewatches.net/out/h_8049503994035", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8049503994035/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8049503994035/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_8049503994035/via/farfetch"}], "available": false}, {"id": "h_7808425787618", "title": "IWC IWC Portugese Hand Wound Eight Days | REF.
