Collectors prioritize this reference for its functional moisture indicator located at six o'clock, a circular disk designed to change color from blue to pink if water entered the 41mm stainless steel case. It typically houses the automatic Caliber AS 1361 or the upgraded Caliber R.310. This reference is historically significant as it met the rigorous technical specifications of the United States Navy Experimental Diving Unit. On the secondary market, authentic examples generally command prices between $80,000 and $150,000 depending on condition and provenance. A notable variant is the \"US Navy\" signed dial, which is particularly rare; a well-preserved Milspec 1 with this distinction achieved a sale price of approximately $125,000 at a 2021 Phillips auction."}, "listing_stats": {"count": 3, "median": 26500.0, "low": 22000.0, "high": 27250.0, "brands": 1, "merchants": 3}, "listings": [{"id": "h_8011175526509", "title": "Blancpain 2021 Blancpain Fifty-Fathoms Mil-Spec (Ref. 5008-11B30-NABA) \"Hodinkee Limited Edition\" W/ Full Set", "brand": "Blancpain", "model": "2021 Blancpain Fifty-Fathoms Mil-Spec (Ref. 5008-11B30-NABA) \"Hodinkee Limited Edition\" W/ Full Set", "reference": "5008-11B30", "price_usd": 27250.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "craft-and-tailored", "merchant_name": "Craft + Tailored", "image_url": "https://cdn.shopify.com/s/files/1/1104/9180/files/Img041943.jpg?v=1773099892", "detail_url": "https://mostexpensivewatches.net/listing/h_8011175526509", "buy_url": "https://mostexpensivewatches.net/out/h_8011175526509", "available": false}, {"id": "h_7419170914391", "title": "Blancpain Blancpain Fifty Fathoms MIL-SPEC Limited Edition for HODINKEE 'New Old Stock'", "brand": "Blancpain", "model": "Blancpain Fifty Fathoms MIL-SPEC Limited Edition for HODINKEE 'New Old Stock'", "reference": "40992334", "price_usd": 26500.0, "currency": "USD", "condition": "unworn", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS10568_40992334_BLANCPAIN_FIFTYFATHOMSMIL-SPECHODINKEEEDITION_500811B30NABA-5.jpg?v=1748363920", "detail_url": "https://mostexpensivewatches.net/listing/h_7419170914391", "buy_url": "https://mostexpensivewatches.net/out/h_7419170914391", "available": false}, {"id": "h_6930712526923", "title": "Blancpain Blancpain Blancpain Fifty Fathoms MIL-SPEC Limited Edition for HODINKEE 5008 11B30 NABA", "brand": "Blancpain", "model": "Blancpain Blancpain Fifty Fathoms MIL-SPEC Limited Edition for HODINKEE 5008 11B30 NABA", "reference": "5008", "price_usd": 22000.0, "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/Blancpain-Blancpain-Fifty-Fathoms-MIL-SPEC-Limited-Edition-for-HODINKEE-5008-11B30-NABA-10-10-BLP-3X04GQ-a9658f393ae3_76ee60e6-a32d-4cfc-958f-12bc0d25fb93.jpg?v=1709928741", "detail_url": "https://mostexpensivewatches.net/listing/h_6930712526923", "buy_url": "https://mostexpensivewatches.net/out/h_6930712526923", "available": false}], "auction_lots": [{"slug": "blancpain-milspec-i-2016", "brand": "Blancpain", "reference": "Milspec I", "model": "Fifty Fathoms Milspec I", "case_material": "Stainless Steel", "hammer_usd": 22500, "year_sold": 2016, "venue": "Christie's New York", "lot_summary": "A rare military-specification diver's watch in original condition, believed to have been owned by a member of the United States military.", "source_url": "https://www.christies.com/lot/lot-6045145", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/blancpain-milspec-i-2016"}, {"slug": "blancpain-milspec-1-2021", "brand": "Blancpain", "reference": "Milspec 1", "model": "Fifty Fathoms Milspec 1", "case_material": "Stainless Steel", "hammer_usd": 19230, "year_sold": 2021, "venue": "Christie's Hong Kong", "lot_summary": "A vintage 1950s military-spec diver's watch from an important Asian private collection.", "source_url": "https://www.christies.com/lot/lot-6334567", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/blancpain-milspec-1-2021"}]}
