This reference is distinguished by its case construction, which utilizes sandblasted titanium paired with a polished bezel and studs made of a palladium-based Bulk Metallic Glass (BMG). This marked the first time the manufacturer employed BMG, a material valued for its high resistance to scratches and corrosion. The watch features a grey \"Petite Tapisserie\" dial and is powered by the caliber 2121, the final instance of this movement being used in a 15202 reference before its retirement. As a unique piece, it does not have a standard secondary market price range; however, it sold at Christie’s in November 2021 for 3,100,000 CHF. This result represents one of the highest prices ever paid for a Royal Oak at auction."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "audemars-piguet-15202xt-gg-1240xt-99-2021", "brand": "Audemars Piguet", "reference": "15202XT.GG.1240XT.99", "model": "Royal Oak \"Jumbo\" Extra-Thin Only Watch", "case_material": "Titanium and Bulk Metallic Glass", "hammer_usd": 3400700, "year_sold": 2021, "venue": "Christie's Geneva", "lot_summary": "A unique piece created for the Only Watch 2021 charity auction, this was the last unique 15202 powered by the legendary Calibre 2121 and the first AP to use Bulk Metallic Glass.", "source_url": "https://www.christies.com/en/lot/lot-6338515", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/audemars-piguet-15202xt-gg-1240xt-99-2021"}]}
