This unique piece is not in production. Collectors value the reference for its high-complication movement, featuring a carrousel tourbillon, grande and petite sonnerie, minute repeater, perpetual calendar, and split-seconds chronograph. The 18k yellow gold case measures 65mm and houses a silvered dial with the Egyptian royal coat of arms in enamel on the caseback. The movement contains 46 jewels and was adjusted by master watchmaker James Pellaton. While unique pieces of this caliber rarely trade, its historical significance places its valuation in the multi-million dollar range. In 2005, this specific watch sold at Antiquorum for 3,306,250 CHF, setting a record at the time for the most expensive Vacheron Constantin ever sold at auction."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "vacheron-constantin-402833-2005", "brand": "Vacheron Constantin", "reference": "402833", "model": "King Fouad I Pocket Watch", "case_material": "18k Yellow Gold", "hammer_usd": 2755000, "year_sold": 2005, "venue": "Antiquorum Geneva", "lot_summary": "An exceptionally complicated pocket watch made for King Fouad I of Egypt in 1929, featuring a carillon minute repeater and split-seconds chronograph; it set a world record for a Vacheron Constantin at the time.", "source_url": "https://www.antiquorum.swiss/history/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/vacheron-constantin-402833-2005"}]}
