This reference is distinguished by its 46.2mm case constructed from 18k red gold and a midnight blue sunray-brushed dial featuring an annual calendar complication. It houses the manufacture caliber 52850, which provides a seven-day power reserve. Collectors value this specific watch for its unique movement execution; the solid gold oscillating weight is sandblasted and shaped to depict the Little Prince standing on an asteroid. As a unique piece, it does not have a standard secondary market price range, though it sold at the 2016 Christie’s Only Watch auction for 38,000 CHF. It remains the only example of this reference ever produced, marking a significant entry in the brand’s partnership with the Antoine de Saint-Exupéry Youth Foundation."}, "listing_stats": {"count": 1, "median": 11600.0, "low": 11600.0, "high": 11600.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6894016921675", "title": "IWC IWC Big Pilot Spitfire Annual Calendar IW5027-02", "brand": "IWC", "model": "IWC Big Pilot Spitfire Annual Calendar IW5027-02", "reference": "IW5027", "price_usd": 11600.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Annual Calendar"], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/IWC-Big-Pilot-Spitfire-IW5027-02-10-10-IWC-1VC4QS-7893e2db5bf4.jpg?v=1710687346", "detail_url": "https://mostexpensivewatches.net/listing/h_6894016921675", "buy_url": "https://mostexpensivewatches.net/out/h_6894016921675", "available": false}], "auction_lots": [{"slug": "iwc-iw502704-2015", "brand": "IWC", "reference": "IW502704", "model": "Big Pilot's Watch Annual Calendar Edition 'Le Petit Prince' Only Watch", "case_material": "18k Red Gold", "hammer_usd": 48000, "year_sold": 2015, "venue": "Christie's Geneva", "lot_summary": "A unique piece for Only Watch 2015 featuring IWC's first annual calendar movement and a special 'Little Prince' rotor.", "source_url": "https://www.christies.com/en/lot/lot-5949824", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/iwc-iw502704-2015"}]}
