Lange & Söhne 1815 Chronograph reference 414.049 is a unique piece produced in 2022 specifically for the winner of the \"Best of Show\" award at the Concorso d’Eleganza Villa d’Este. This 39.5mm 18k white gold timepiece features a solid pink gold dial with a hand-engraved hinged cuvette depicting the Concorso d’Eleganza coat of arms. It is powered by the manual-wind caliber L951.5, which includes a column-wheel control, a flyback function, and a 60-hour power reserve. Unlike standard production 1815 models, this reference was never available for retail purchase, making it a one-of-one edition. While standard 1815 chronographs trade between $50,000 and $70,000, this specific commemorative piece is valued significantly higher due to its unique provenance and configuration. Although it has not appeared at public auction recently, its rarity places its estimated secondary market value in the mid-to-high six-figure range."}, "listing_stats": {"count": 1, "median": 60000.0, "low": 60000.0, "high": 60000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6766398111827", "title": "A.
