Collectors prioritize this reference for its ultra-thin 8.52mm case profile and the caliber 240 PS IRM C LU, an automatic movement featuring a 22k gold micro-rotor. The asymmetrical dial layout includes a power reserve indicator, moon phase, and pointer date, set against a blue-grey gradient finish with horizontal embossing. Unlike the standard 5711, the 5712 features a four-part case construction and a sapphire crystal caseback. On the secondary market, prices typically range from $90,000 to $120,000 depending on condition and provenance. A notable production variant is the \"Geneva Seal\" version produced between 2006 and mid-2009, which preceded the transition to the proprietary Patek Philippe Seal found on modern examples."}, "listing_stats": {"count": 3, "median": 95500.0, "low": 73850.0, "high": 279000.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7739651948753", "title": "Patek Philippe Patek Philippe Nautilus 5712/1R-001", "brand": "Patek Philippe", "model": "Patek Philippe Nautilus 5712/1R-001", "reference": "5712/1R-001", "price_usd": 279000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Rose Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "material-good", "merchant_name": "Material Good", "image_url": "https://cdn.shopify.com/s/files/1/0561/5190/0369/files/Patek_Philippe_Nautilus_5712_1R-001.jpg?v=1777671215", "detail_url": "https://mostexpensivewatches.net/listing/h_7739651948753", "buy_url": "https://mostexpensivewatches.net/out/h_7739651948753", "available": true}, {"id": "h_7756045025489", "title": "Patek Philippe Patek Philippe Nautilus 5712G-001", "brand": "Patek Philippe", "model": "Patek Philippe Nautilus 5712G-001", "reference": "5712G-001", "price_usd": 95500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k White Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "material-good", "merchant_name": "Material Good", "image_url": "https://cdn.shopify.com/s/files/1/0561/5190/0369/files/Patek_Philippe_Nautilus_5712G-001.jpg?v=1781278706", "detail_url": "https://mostexpensivewatches.net/listing/h_7756045025489", "buy_url": "https://mostexpensivewatches.net/out/h_7756045025489", "available": true}, {"id": "h_6599414972499", "title": "Patek Philippe Nautilus 5712-1A-001 | Steel", "brand": "Patek Philippe", "model": "Nautilus 5712-1A-001 | Steel", "reference": "5712-1A-001", "price_usd": 73850.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Patek_Philippe_Nautilus_5712A_stainless_steel_A_Collected_Man.jpg?v=1631268281", "detail_url": "https://mostexpensivewatches.net/listing/h_6599414972499", "buy_url": "https://mostexpensivewatches.net/out/h_6599414972499", "available": false}], "auction_lots": [{"slug": "patek-philippe-5712-1a-001-2023", "brand": "Patek Philippe", "reference": "5712/1A-001", "model": "Nautilus", "case_material": "Stainless Steel", "hammer_usd": 97000, "year_sold": 2023, "venue": "Bonhams London", "lot_summary": "A modern stainless steel Nautilus featuring a moon phase and power reserve indicator, representing the enduring popularity of Gerald Genta's iconic porthole design.", "source_url": "https://www.bonhams.com/auctions/28011/lot/102/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/patek-philippe-5712-1a-001-2023"}]}
