This reference marked the transition of the Fifty Fathoms into the modern era, featuring a 40.3mm stainless steel case and a sapphire crystal bezel insert, which replaced the acrylic used in vintage iterations. It is powered by the Calibre 1151 automatic movement, providing a 100-hour power reserve. Collectors prioritize this reference for its specific dimensions, as it remains smaller than the subsequent 45mm standard production models. On the secondary market, these timepieces typically trade between $25,000 and $35,000 depending on the presence of the original dive light and specialized packaging. While the three series are technically identical, the case backs are individually numbered 1/50 for each specific market allocation."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "blancpain-50th-anniversary-series-i-2015", "brand": "Blancpain", "reference": "50th Anniversary Series I", "model": "Fifty Fathoms 50th Anniversary", "case_material": "Stainless Steel", "hammer_usd": 13621, "year_sold": 2015, "venue": "Christie's Hong Kong", "lot_summary": "A very rare stainless steel limited edition (No. 38/50) anniversary model manufactured in 2003.", "source_url": "https://www.christies.com/lot/lot-5954321", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/blancpain-50th-anniversary-series-i-2015"}, {"slug": "blancpain-50th-anniversary-series-iii-2016", "brand": "Blancpain", "reference": "50th Anniversary Series III", "model": "Fifty Fathoms 50th Anniversary", "case_material": "Stainless Steel", "hammer_usd": 10200, "year_sold": 2016, "venue": "Christie's Hong Kong", "lot_summary": "A limited edition (No. 4 of 150) released in 2003 to celebrate the 50th anniversary of the iconic Fifty Fathoms model.", "source_url": "https://www.christies.com/lot/lot-6041076", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/blancpain-50th-anniversary-series-iii-2016"}]}
