Collectors prioritize this reference for its hand-finished Caliber 11 movement, which features internal angles and bridge work executed to historical Vallée de Joux standards. The platinum case was typically offered in 34mm or 37mm diameters, often paired with a silver guilloché dial or a white lacquer dial with Roman numerals. Total production across all metals is estimated at fewer than 250 units, making the platinum version rare. On the secondary market, prices currently range from $700,000 to over $1,000,000 depending on case size and provenance. A notable auction result occurred in 2020 when a 37mm 20th Anniversary model in platinum, numbered 00/20, sold for approximately $1.5 million, reflecting the high demand for these later production pieces."}, "listing_stats": {"count": 6, "median": 515000.0, "low": 445000.0, "high": 680000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6670178844755", "title": "Philippe Dufour
