This 44mm 18k white gold timepiece houses the caliber 2885, a self-winding movement composed of 648 parts. It integrates three traditional high complications: a minute repeater, a perpetual calendar, and a split-seconds chronograph. Collectors prioritize this reference for its technical density and the hand-finished nature of its movement, which includes a solid gold oscillating weight and a chime sequence struck on two gongs. The dial typically features a silvered \"Grande Tapisserie\" pattern with white gold applied hour markers. On the secondary market, this reference generally commands prices in the mid-to-high six-figure range, often between $450,000 and $700,000 depending on provenance. A notable production detail is that each unit required over 600 hours of assembly by a single master watchmaker at the brand’s Grandes Complications workshop."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "audemars-piguet-25865bc-oo-1105bc-01-2020", "brand": "Audemars Piguet", "reference": "25865BC.OO.1105BC.01", "model": "Royal Oak Grand Complication", "case_material": "18k White Gold", "hammer_usd": 441000, "year_sold": 2020, "venue": "Sotheby's New York", "lot_summary": "Features the 'holy trinity' of complications—split-second chronograph, perpetual calendar, and minute repeater—with a rare salmon dial.", "source_url": "https://www.sothebys.com/en/articles/the-six-most-expensive-audemars-piguet-royal-oak-watches", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/audemars-piguet-25865bc-oo-1105bc-01-2020"}]}
