Collectors prioritize this reference for its manual-winding caliber RM052, which features a baseplate and bridges shaped from grade 5 titanium to form a skull motif that integrates the tourbillon cage within the \"jaws.\" The case utilizes a specialized layering process of silica and carbon fibers to create a high-strength, lightweight marbled aesthetic. This model represents a technical evolution of the original 2012 RM 052, marking a significant point in the brand’s experimentation with advanced composite materials. On the secondary market, these timepieces typically command prices in the mid-to-high seven-figure range, often exceeding $2,500,000 depending on provenance. A notable production detail is the use of 18k red gold for the skull structure in this specific material configuration."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "richard-mille-rm52-01-ca-fq-2024", "brand": "Richard Mille", "reference": "RM52-01 CA-FQ", "model": "Skull Tourbillon", "case_material": "White Quartz Carbon TPT", "hammer_usd": 1260000, "year_sold": 2024, "venue": "Christie's New York", "lot_summary": "A rare white quartz carbon TPT skeletonized tourbillon featuring the iconic skull design with diamond-set teeth.", "source_url": "https://www.christies.com/en/lot/lot-6484165", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/richard-mille-rm52-01-ca-fq-2024"}]}
