This reference is no longer in production. Collectors prioritize this model for the manual-wind Calibre 177, which features a spherical, biaxial tourbillon designed to compensate for positional errors. The movement includes a perpetual calendar with retrograde indicators, an equation of time function, and an eight-day power reserve supported by two barrels. The 43mm platinum case houses a rhodium-plated dial with a visible tourbillon carriage at six o'clock and a sapphire caseback revealing the movement's finishing. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often between $300,000 and $500,000 depending on provenance. A notable auction result occurred in 2021 when a well-preserved example sold for approximately $430,000, confirming its status as a significant technical milestone for the manufacture."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "jaeger-lecoultre-149-6-07-s-2015", "brand": "Jaeger-LeCoultre", "reference": "149.6.07.S", "model": "Gyrotourbillon 1", "case_material": "Platinum", "hammer_usd": 230000, "year_sold": 2015, "venue": "Phillips Hong Kong", "lot_summary": "A landmark in modern horology, this multi-axis tourbillon with perpetual calendar and equation of time cemented JLC's status as a high-complication manufacture.", "source_url": "https://www.phillips.com/detail/jaeger-lecoultre/HK080115/354", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/jaeger-lecoultre-149-6-07-s-2015"}, {"slug": "jaeger-lecoultre-149-6-34-s-2014", "brand": "Jaeger-LeCoultre", "reference": "149.6.34.S", "model": "Master Tourbillon", "case_material": "Platinum", "hammer_usd": 37500, "year_sold": 2014, "venue": "Christie's New York", "lot_summary": "A very fine platinum limited edition automatic dual time tourbillon wristwatch with date.", "source_url": "https://www.christies.com/en/lot/lot-5804157", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/jaeger-lecoultre-149-6-34-s-2014"}]}
