This reference is distinguished by its 42.5mm case constructed from titanium with a bezel and crown guards made of boron carbide, a ceramic material noted for its extreme hardness. Collectors value the model for its use of the in-house caliber 80110, which features the Pellaton winding system and an integrated shock absorption mechanism. The dial is black with a textured \"I\" pattern and lacks the \"AMG\" branding found on other contemporary collaborations. On the secondary market, the IW322702 typically trades between $6,000 and $9,000 depending on condition and the presence of original accessories. A notable production detail is that this was the first time IWC utilized boron carbide, a material more commonly used in tank armor and industrial abrasives, in watchmaking."}, "listing_stats": {"count": 2, "median": 7375.0, "low": 4500.0, "high": 10250.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_16292299047257", "title": "IWC IWC Ingenieur Automatic SL Khanjar Dial ref 3505 Steel and Gold Execution", "brand": "IWC", "model": "IWC Ingenieur Automatic SL Khanjar Dial ref 3505 Steel and Gold Execution", "reference": "3505", "price_usd": 10250.0, "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-3752IWCIngenieurAutomaticSLKhanjardial_283_1x1_38b36e15-b18c-46b8-b1f1-017a8a7f92ce.jpg?v=1778224443", "detail_url": "https://mostexpensivewatches.net/listing/h_16292299047257", "buy_url": "https://mostexpensivewatches.net/out/h_16292299047257", "available": true}, {"id": "h_6865526194251", "title": "IWC IWC Ingenieur Automatic IW3570-02", "brand": "IWC", "model": "IWC Ingenieur Automatic IW3570-02", "reference": "IW3570", "price_usd": 4500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/IWC-Ingenieur-IW3570-02-10-10-IWC-CZL2X1-f3f46bb8c4d8.jpg?v=1698593518", "detail_url": "https://mostexpensivewatches.net/listing/h_6865526194251", "buy_url": "https://mostexpensivewatches.net/out/h_6865526194251", "available": false}], "auction_lots": [{"slug": "iwc-iw322702-2015", "brand": "IWC", "reference": "IW322702", "model": "Ingenieur Automatic \"Tribute to Nico Rosberg\"", "case_material": "Boron Carbide", "hammer_usd": 25000, "year_sold": 2015, "venue": "Phillips Geneva", "lot_summary": "A unique piece created for Only Watch 2015, featuring the first-ever watch case made from boron carbide.", "source_url": "https://www.phillips.com/detail/iwc/CH080215/14", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/iwc-iw322702-2015"}]}
