Collectors prioritize this reference for its technical construction, featuring a tripartite case milled entirely from solid blocks of synthetic sapphire, a process requiring over 1,000 hours of machining per watch. It houses the manual-winding Caliber RMCC1, a split-seconds tourbillon movement with power reserve and torque indicators. Due to its extreme rarity and status as the brand’s first full-sapphire model, secondary market prices typically range from $3,000,000 to $5,000,000 depending on provenance. A notable production evolution followed in 2013 with the RM 56-01, which incorporated sapphire baseplates and bridges, further reducing the use of titanium in the movement architecture."}, "listing_stats": {"count": 1, "median": 2207500.0, "low": 2207500.0, "high": 2207500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_8029493854530", "title": "Richard Mille 056 Jean Todt 50th Anniversary", "brand": "Richard Mille", "model": "056 Jean Todt 50th Anniversary", "reference": "056", "price_usd": 2207500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 70.0, "movement": "Automatic", "complications": [], "merchant_slug": "watch-affinity", "merchant_name": "Watch-Affinity", "image_url": "https://cdn.shopify.com/s/files/1/0683/2449/1586/products/richard-mille-rm-056-jean-todt-50th-anniversary-800x1023_9ac9f476-ff58-4abf-938a-16eb67a5f229.jpg?v=1669756751", "detail_url": "https://mostexpensivewatches.net/listing/h_8029493854530", "buy_url": "https://mostexpensivewatches.net/out/h_8029493854530", "available": false}], "auction_lots": [{"slug": "richard-mille-rm056-prototype-no-2-2017", "brand": "Richard Mille", "reference": "RM056 Prototype No. 2", "model": "Felipe Massa Sapphire", "case_material": "Sapphire Crystal", "hammer_usd": 1207500, "year_sold": 2017, "venue": "Christie's New York", "lot_summary": "A landmark prototype of the first sapphire-cased Richard Mille, featuring one of the brand's most complicated movements.", "source_url": "https://www.christies.com/en/lot/lot-6083543", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/richard-mille-rm056-prototype-no-2-2017"}]}
