Jaeger-LeCoultre Gyrotourbillon 1

About this reference

The Jaeger-LeCoultre Gyrotourbillon 1, reference 149.6.07.S, was introduced in 2004 as a limited edition of 75 pieces in platinum. 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.
