Collectors value this reference for its specialized 42mm Super-Compressor case, which features a triple-layered caseback designed to optimize the acoustic resonance of the alarm underwater. It utilizes the caliber 825 automatic movement, a bumper-style caliber with a date function and a mechanical alarm. The dial is characterized by its three-part construction, including a rotating internal bezel controlled by one of the three oversized crowns. Due to its limited production and role as a purpose-built diving tool, the E859 occupies a significant position in the brand's professional instrument history. Current secondary market prices typically range from $15,000 to $35,000 depending on condition and dial configuration. A notable 1968 variant features \"polished\" luminous indices, which often command higher premiums at auction than the standard 1965 execution."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "jaeger-lecoultre-e859-2019", "brand": "Jaeger-LeCoultre", "reference": "E859", "model": "Memovox Polaris", "case_material": "Stainless Steel", "hammer_usd": 40200, "year_sold": 2019, "venue": "Phillips Geneva", "lot_summary": "A highly sought-after 1968 dive watch with alarm, notable for its large 42mm case and internal rotating bezel.", "source_url": "https://www.phillips.com/detail/jaeger-lecoultre/CH080219/194", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/jaeger-lecoultre-e859-2019"}, {"slug": "jaeger-lecoultre-e859-2023", "brand": "Jaeger-LeCoultre", "reference": "E859", "model": "Memovox Polaris", "case_material": "Stainless Steel", "hammer_usd": 28224, "year_sold": 2023, "venue": "Christie's Geneva", "lot_summary": "A rare stainless steel automatic diver's wristwatch with alarm and date, manufactured in 1968.", "source_url": "https://www.christies.com/en/lot/lot-6424366", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/jaeger-lecoultre-e859-2023"}, {"slug": "jaeger-lecoultre-e859-2014", "brand": "Jaeger-LeCoultre", "reference": "E859", "model": "Memovox Polaris", "case_material": "Stainless Steel", "hammer_usd": 21250, "year_sold": 2014, "venue": "Christie's New York", "lot_summary": "A stainless steel automatic diver's wristwatch with sweep centre seconds, alarm, and date, manufactured in 1968.", "source_url": "https://www.christies.com/en/lot/lot-5804192", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/jaeger-lecoultre-e859-2014"}]}
