Lange & Söhne Lange 1 Tourbillon reference 704.025 in platinum was released in 2000 as a limited edition of 150 pieces to mark the turn of the century. It features the manual-wind caliber L961.1, which incorporates 378 components, twin mainspring barrels for a 72-hour power reserve, and a one-minute tourbillon visible through a dial aperture at 4 o'clock. The 38.5mm case houses a solid silver dial with the signature offset layout and oversized date. Collectors value this reference as the first tourbillon in the Lange 1 family and for its technical execution, including the patented stop-seconds mechanism that allows for precise synchronization. On the secondary market, this platinum reference typically trades in the $120,000 to $160,000 range depending on provenance. A notable 2000 production detail is the use of two diamond endstones for the tourbillon cage, a traditional high-grade finishing touch."}, "listing_stats": {"count": 13, "median": 195000.0, "low": 47000.0, "high": 290000.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7350007005271", "title": "A.
