Collectors prioritize this reference for its 42.3mm stainless steel case, a reduction from the standard 45mm Fifty Fathoms, and its use of the caliber 1315 automatic movement with a five-day power reserve. The dial features a black sunburst finish with vintage-style luminous markers and a sapphire bezel insert. On the secondary market, these watches typically trade between $25,000 and $35,000. While this specific reference was a commercial release, it shares its 42mm architecture with the unique 2023 \"Only Watch\" edition, which featured a blue dial and sold at auction for 160,000 CHF, signaling high demand for the mid-sized steel case format within the brand's modern catalog."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "blancpain-5010-1140-naoa-2024", "brand": "Blancpain", "reference": "5010 1140 NAOA", "model": "Fifty Fathoms 70th Anniversary Act 1 Only Watch", "case_material": "Stainless Steel", "hammer_usd": 45000, "year_sold": 2024, "venue": "Christie's Geneva", "lot_summary": "A unique blue-themed edition celebrating the 70th anniversary of the Fifty Fathoms, sold for charity.", "source_url": "https://www.christies.com/lot/lot-6447814", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/blancpain-5010-1140-naoa-2024"}]}
