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": 5, "median": 5500.0, "low": 3850.0, "high": 15900.0, "brands": 1, "merchants": 1}, "listings": [{"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", "available": false}, {"id": "h_15917014253913", "title": "IWC IWC Yacht Club 2 ref 3312 Steel by Gerald Genta", "brand": "IWC", "model": "IWC Yacht Club 2 ref 3312 Steel by Gerald Genta", "reference": "3312", "price_usd": 6500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 38.0, "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-2272IWCYachtClub2Ref3312SteelbyGeraldGenta_002_1x1_886e6284-7f0a-4152-8204-31f676a396c2.jpg?v=1765279390", "detail_url": "https://mostexpensivewatches.net/listing/h_15917014253913", "buy_url": "https://mostexpensivewatches.net/out/h_15917014253913", "available": false}, {"id": "h_15751339475289", "title": "IWC IWC Yacht Club 2 3311 Steel and Gold Khanjar Dial", "brand": "IWC", "model": "IWC Yacht Club 2 3311 Steel and Gold Khanjar Dial", "reference": "3311", "price_usd": 5500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 38.0, "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-1817IWCYachtclub2Khanjar_006_1x1_6723bdbd-8781-4145-a03f-681c2cec98d3.jpg?v=1756205324", "detail_url": "https://mostexpensivewatches.net/listing/h_15751339475289", "buy_url": "https://mostexpensivewatches.net/out/h_15751339475289", "available": false}, {"id": "h_15807092752729", "title": "IWC IWC Yacht Club 2 White Dial Roman Numerals ref. 3311", "brand": "IWC", "model": "IWC Yacht Club 2 White Dial Roman Numerals ref. 3311", "reference": "3311", "price_usd": 4500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 38.0, "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-3189IWCYachtclub2whitedialRomannumerals_359_1x1_412827b2-75e4-475c-a1f2-e651bdd9680d.jpg?v=1758010194", "detail_url": "https://mostexpensivewatches.net/listing/h_15807092752729", "buy_url": "https://mostexpensivewatches.net/out/h_15807092752729", "available": false}, {"id": "h_15751347339609", "title": "IWC IWC Yacht Club 2 Steel and Gold by Gerald Genta", "brand": "IWC", "model": "IWC Yacht Club 2 Steel and Gold by Gerald Genta", "reference": "W-1758", "price_usd": 3850.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 38.0, "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-1758IWCYachtClub2SteelGold_011_1x1_0b4be678-ae8f-450e-86b0-1d656227d533.jpg?v=1756205490", "detail_url": "https://mostexpensivewatches.net/listing/h_15751347339609", "buy_url": "https://mostexpensivewatches.net/out/h_15751347339609", "available": false}], "auction_lots": [{"slug": "iwc-1811-2021", "brand": "IWC", "reference": "1811", "model": "Yacht Club", "case_material": "Stainless Steel", "hammer_usd": 23500, "year_sold": 2021, "venue": "Phillips Geneva", "lot_summary": "The only known specimen featuring a unique blue dial and matching blue date ring, confirmed as an original design experiment by IWC.", "source_url": "https://www.phillips.com/detail/iwc/CH080121/139", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/iwc-1811-2021"}]}
