Lange & Söhne Tourbillon Pour le Mérite reference 701.007 in 18k white gold was produced between 1994 and 1998 as part of the brand’s initial launch collection. Collectors prioritize this reference for its Calibre L902.0 movement, which was the first wristwatch movement to incorporate a fusée-and-chain transmission system to ensure constant force. The white gold variant is particularly rare, with only 19 pieces produced out of the total 200-unit run across all metals. It features a 38.5mm case, a silver dial with blued steel hands, and an aperture at six o'clock revealing the one-minute tourbillon. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often exceeding $500,000. A notable auction result occurred in 2021 when a white gold example sold for approximately $800,000, reflecting its scarcity compared to the more common yellow gold and platinum versions."}, "listing_stats": {"count": 2, "median": 227500.0, "low": 165000.0, "high": 290000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7095329161299", "title": "A.
