Jaeger-LeCoultre Reverso Gyrotourbillon 2

About this reference

The Jaeger-LeCoultre Reverso Gyrotourbillon 2, reference 233.64.20, was released in 2008 as a limited edition of 75 pieces in platinum. Collectors prioritize this reference for the Calibre 174, which features a spherical biaxial tourbillon rotating at high speeds—the inner carriage every 18.75 seconds and the outer every 60 seconds. It is notable for incorporating a cylindrical balance spring, a feature historically reserved for marine chronometers to improve isochronism. The reversible platinum case is significantly thicker than standard Reversos to accommodate the three-dimensional movement, and the dial is skeletonized with blued steel hands and a 50-hour power reserve indicator on the reverse. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often between $200,000 and $350,000 depending on condition. A notable production detail is that this was the first time the Gyrotourbillon complication was integrated into the rectangular Reverso case.
