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": 2, "median": 16500.0, "low": 4500.0, "high": 28500.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7569231380567", "title": "Jaeger-LeCoultre Jaeger-LeCoultre Polaris Alarm 'First Series'", "brand": "Jaeger-LeCoultre", "model": "Jaeger-LeCoultre Polaris Alarm 'First Series'", "reference": "—", "price_usd": 28500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS11460_40980127_JAEGERLECOULTRE_POLARISALARMFIRSTSERIESEUROPEANMARKET_E859--6.jpg?v=1770990941", "detail_url": "https://mostexpensivewatches.net/listing/h_7569231380567", "buy_url": "https://mostexpensivewatches.net/out/h_7569231380567", "available": false}, {"id": "h_4895990415469", "title": "Jaeger-LeCoultre 1970s Jaeger-LeCoultre Memovox Polaris II (Ref.
