This reference features a 44mm case crafted from 18k white gold, housing the self-winding caliber 2885. The movement integrates three traditional high complications: a minute repeater, a perpetual calendar with moon phase, and a split-seconds chronograph. Collectors value this reference for its complexity and the hand-finished nature of its 648 components. The dial typically features the signature Petite Tapisserie pattern with silvered sub-dials. On the secondary market, these timepieces generally command prices in the mid-to-high six-figure range, often between $450,000 and $700,000 depending on condition and provenance. A notable 2021 auction result at Phillips saw a white gold example achieve approximately $500,000, underscoring the sustained demand for these low-volume production pieces."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "audemars-piguet-25990bc-2022", "brand": "Audemars Piguet", "reference": "25990BC", "model": "Royal Oak Grande Complication", "case_material": "18k White Gold", "hammer_usd": 553000, "year_sold": 2022, "venue": "Phillips Geneva", "lot_summary": "A unique white gold Grande Complication featuring a diamond-set case and dial with mother-of-pearl registers.", "source_url": "https://www.phillips.com/detail/audemars-piguet/CH080222/68", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/audemars-piguet-25990bc-2022"}]}
