Collectors target this reference for its 45mm case constructed from zirconium, a rare transition metal valued for its corrosion resistance and distinct grey luster, paired with a black ceramic bezel. It utilizes the HUB1112 automatic movement, based on the Sellita SW300-1, offering a 42-hour power reserve. This model represents the transition from the original 1980s MDM designs to the modern \"Art of Fusion\" era. On the secondary market, this reference typically trades between $4,500 and $6,500 depending on condition and the presence of original documentation. A notable variant includes the Zirconium Diamonds edition, which features a factory-set bezel, though the standard zirconium and ceramic configuration remains the primary choice for those seeking the brand's early technical material applications."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "hublot-501-zm-1670-rx-2019", "brand": "Hublot", "reference": "501.ZM.1670.RX", "model": "Classic Fusion Zirconium", "case_material": "Zirconium and Ceramic", "hammer_usd": 5250, "year_sold": 2019, "venue": "Christie's New York", "lot_summary": "A 45mm zirconium and ceramic automatic wristwatch featuring a carbon fiber print dial.", "source_url": "https://www.christies.com/en/lot/lot-6191108", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/hublot-501-zm-1670-rx-2019"}]}
