This reference is distinguished by its 41mm stainless steel case, a reduction from the previous 43mm standard, and its blue sunray dial with a day-date complication. Collectors value this model for the integration of the IWC-manufactured caliber 69385, a column-wheel chronograph movement visible through a sapphire crystal caseback, marking a shift from the third-party movements used in earlier iterations. The watch features the EasX-CHANGE system for tool-free strap replacement and a water resistance rating of 10 bar. On the secondary market, this reference typically trades between $5,500 and $7,000 depending on condition and completeness. A notable production detail is the inclusion of a stainless steel bracelet with a fine-adjustment clasp, which differentiates it from the leather-strap variant, reference IW3881-01, despite sharing identical technical specifications."}, "listing_stats": {"count": 4, "median": 5750.0, "low": 4025.0, "high": 5750.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6969240584267", "title": "IWC IWC Pilot Chronograph 41 IW3881-01", "brand": "IWC", "model": "IWC Pilot Chronograph 41 IW3881-01", "reference": "IW3881", "price_usd": 5750.0, "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": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/IWC-Pilot-IW3881-01-10-10-IWC-XZC78M-53f2f2233018.jpg?v=1710861356", "detail_url": "https://mostexpensivewatches.net/listing/h_6969240584267", "buy_url": "https://mostexpensivewatches.net/out/h_6969240584267", "available": false}, {"id": "h_6895298609227", "title": "IWC IWC Pilot Chronograph 41 IW3881-01", "brand": "IWC", "model": "IWC Pilot Chronograph 41 IW3881-01", "reference": "IW3881", "price_usd": 5750.0, "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": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/IWC-Pilot-IW3881-01-10-10-IWC-UK4SB2-e918c2a0c686_74218e6c-cfce-41f0-a513-34b9604d21e6.jpg?v=1703729350", "detail_url": "https://mostexpensivewatches.net/listing/h_6895298609227", "buy_url": "https://mostexpensivewatches.net/out/h_6895298609227", "available": false}, {"id": "h_6879221743691", "title": "IWC IWC Pilot Chronograph 41 IW3881-01", "brand": "IWC", "model": "IWC Pilot Chronograph 41 IW3881-01", "reference": "IW3881", "price_usd": 5750.0, "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": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/IWC-Pilot-IW3881-01-10-10-IWC-FE9Q8H-0fdc27f2f689.jpg?v=1700663523", "detail_url": "https://mostexpensivewatches.net/listing/h_6879221743691", "buy_url": "https://mostexpensivewatches.net/out/h_6879221743691", "available": false}, {"id": "h_6857061367883", "title": "IWC IWC Pilot Chronograph 41 IW3881-01", "brand": "IWC", "model": "IWC Pilot Chronograph 41 IW3881-01", "reference": "IW3881", "price_usd": 4025.0, "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": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/IWC-Pilot-IW3881-01-10-10-IWC-R48DQH-7416ee88e6b7.jpg?v=1696950083", "detail_url": "https://mostexpensivewatches.net/listing/h_6857061367883", "buy_url": "https://mostexpensivewatches.net/out/h_6857061367883", "available": false}], "auction_lots": [{"slug": "iwc-iw3881-02-2024", "brand": "IWC", "reference": "IW3881-02", "model": "Pilot's Watch Chronograph 41", "case_material": "Stainless Steel", "hammer_usd": 72000, "year_sold": 2024, "venue": "Sotheby's New York", "lot_summary": "A personal watch of Tom Brady, this stainless steel chronograph with a blue dial significantly outperformed its estimate due to its high-profile provenance.", "source_url": "https://www.sothebys.com/en/buy/auction/2024/the-goat-collection-watches-treasures-from-tom-brady/reference-iw3881-02-pilots-watch-a-stainless-steel", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/iwc-iw3881-02-2024"}]}
