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.", "score": 199}]}
