This specific reference is distinguished by its 46mm case constructed from 950 platinum and a midnight blue sunray-brushed dial. It houses the caliber 51613 automatic movement, featuring a seven-day power reserve and a perpetual calendar with a specialized moon phase display at 12 o'clock, which depicts the Little Prince standing on his planet. The exhibition case back reveals a 21-carat gold medallion on the rotor engraved with the same motif. At its 2013 auction debut, the watch sold for 173,000 CHF. Given its status as a unique piece, secondary market availability is non-existent, though its valuation remains in the mid-to-high six-figure range based on its historical significance as the first \"Le Petit Prince\" perpetual calendar."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "iwc-iw502801-2013", "brand": "IWC", "reference": "IW502801", "model": "Big Pilot's Watch Perpetual Calendar 'Le Petit Prince' Unique Piece", "case_material": "Platinum", "hammer_usd": 190000, "year_sold": 2013, "venue": "Christie's Geneva", "lot_summary": "A unique platinum execution with a midnight blue dial, sold to benefit the Antoine de Saint-Exupéry Youth Foundation.", "source_url": "https://www.christies.com/en/lot/lot-5739343", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/iwc-iw502801-2013"}]}
