Collectors target this reference for its 42mm titanium construction, which offers a lighter alternative to the heavier steel and gold variants of the era. It is powered by the self-winding caliber 2120/2802, a movement based on the ultra-thin JLC 920 ebauche integrated with a perpetual calendar module. The dial typically features the \"Petite Tapisserie\" pattern with four sub-dials indicating day, date, month, leap year, and moon phase. Due to limited production numbers, these pieces appear infrequently on the secondary market, generally commanding prices in the $60,000 to $90,000 range depending on condition and provenance. A notable variant includes the 25854ST in stainless steel, though the titanium 25854TI remains distinct for its specific matte finish and weight profile."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "audemars-piguet-25854ti-2022", "brand": "Audemars Piguet", "reference": "25854TI", "model": "Royal Oak Offshore Perpetual Calendar", "case_material": "Titanium", "hammer_usd": 32500, "year_sold": 2022, "venue": "Christie's Dubai", "lot_summary": "A rare titanium Offshore combining the ruggedness of the ROO line with the high complication of a perpetual calendar and chronograph.", "source_url": "https://www.christies.com/en/lot/lot-6391234", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/audemars-piguet-25854ti-2022"}]}
