This reference is distinguished by its 41mm case and integrated bracelet constructed entirely from 950 platinum, making it significantly heavier than steel or titanium counterparts. It houses the manual-wind Calibre 2924, which measures 4.46mm thick and provides a 70-hour power reserve. The dial features a blue \"Petite Tapisserie\" pattern with a visible tourbillon cage at the six o'clock position. Collectors value this reference for its combination of a high-complication movement with the density of platinum and its limited availability compared to standard gold models. On the secondary market, this reference typically trades in the mid-to-high six-figure range. A notable variant includes the 26511TR, which utilizes a bi-metal construction of titanium and ruthenium."}, "listing_stats": {"count": 3, "median": 165000.0, "low": 115000.0, "high": 189500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7694167703761", "title": "Audemars Piguet Audemars Piguet Royal Oak Offshore Tourbillon Chronograph 26407TI.GG.A002CA.01", "brand": "Audemars Piguet", "model": "Audemars Piguet Royal Oak Offshore Tourbillon Chronograph 26407TI.GG.A002CA.01", "reference": "26407TI.", "price_usd": 189500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Grade 5 Titanium", "case_size_mm": 44.0, "movement": "Automatic", "complications": ["Tourbillon", "Chronograph"], "merchant_slug": "material-good", "merchant_name": "Material Good", "image_url": "https://cdn.shopify.com/s/files/1/0561/5190/0369/files/54-01388..jpg?v=1768943578", "detail_url": "https://mostexpensivewatches.net/listing/h_7694167703761", "buy_url": "https://mostexpensivewatches.net/out/h_7694167703761", "available": true}, {"id": "h_7708541255889", "title": "Audemars Piguet Audemars Piguet Royal Oak Concept Tourbillon Chronograph 26223TI.OO.D099CR.01", "brand": "Audemars Piguet", "model": "Audemars Piguet Royal Oak Concept Tourbillon Chronograph 26223TI.OO.D099CR.01", "reference": "26223TI.", "price_usd": 165000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Grade 5 Titanium", "case_size_mm": 44.0, "movement": "Automatic", "complications": ["Tourbillon", "Chronograph"], "merchant_slug": "material-good", "merchant_name": "Material Good", "image_url": "https://cdn.shopify.com/s/files/1/0561/5190/0369/files/Audemars_Piguet_Royal_Oak_Concept_Tourbillon_Chronograph_26223TI.OO.D099CR.01.jpg?v=1772903732", "detail_url": "https://mostexpensivewatches.net/listing/h_7708541255889", "buy_url": "https://mostexpensivewatches.net/out/h_7708541255889", "available": true}, {"id": "h_7064143003857", "title": "Audemars Piguet Royal Oak Tourbillon Chronograph 25977ST.OO.D002CR.01", "brand": "Audemars Piguet", "model": "Royal Oak Tourbillon Chronograph 25977ST.OO.D002CR.01", "reference": "25977ST.", "price_usd": 115000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 44.0, "movement": "Automatic", "complications": ["Tourbillon", "Chronograph"], "merchant_slug": "material-good", "merchant_name": "Material Good", "image_url": "https://cdn.shopify.com/s/files/1/0561/5190/0369/products/APROTOURBCHRONOSTEELBLACKDIAL44MM0608.jpg?v=1659110798", "detail_url": "https://mostexpensivewatches.net/listing/h_7064143003857", "buy_url": "https://mostexpensivewatches.net/out/h_7064143003857", "available": true}], "auction_lots": [{"slug": "audemars-piguet-26511pt-2018", "brand": "Audemars Piguet", "reference": "26511PT", "model": "Royal Oak Tourbillon", "case_material": "Platinum", "hammer_usd": 303000, "year_sold": 2018, "venue": "Sotheby's Hong Kong", "lot_summary": "Limited to 40 pieces for the 40th anniversary, this platinum tourbillon features a skeletonized dial and ultra-thin movement.", "source_url": "https://www.sothebys.com/en/articles/the-audemars-piguet-royal-oak-platinum-perfection", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/audemars-piguet-26511pt-2018"}]}
