When Jaeger-LeCoultre introduced the Gyrotourbillon I in 2004, it revolutionized the watch industry as the first spherical tourbillon. This innovative mechanism featuring two carriages positioned at right angles helps wristwatches resist the negative effects of gravity on timekeeping. Jaeger-LeCoultre elevated the concept further with the Reverso's swiveling case, launching the present Reverso Gyrotourbillon 2 collection in 2008.

The calibre 174, comprising 371 parts, showcases exquisite hand-finished details that reflect exceptional craftsmanship. Thanks to the skeletonized dials, the intricate mechanics are a joy to behold. Furthermore, the movement incorporates a cylindrical balance spring, which was invented by John Arnold in 1782. Only a spacious design like the Reverso Gyrotourbillon can accommodate this device, which enhances both precision and aesthetics. The tourbillon's three-dimensional movement captivates observers, with the inner carriage completing a rotation in just 18.75 seconds, while the outer carriage takes one minute. Offering the same benefits to wristwatches that the classic tourbillon provided for pocket watches, it compensates for gravity in all orientations and utilizes lightweight materials for the rapid rotation of both carriages.

This particular example is numbered "28" from a limited edition of just 75 pieces. It has been kept in excellent overall condition and was serviced by Jaeger-LeCoultre in September 2017.
