When Jaeger-LeCoultre decided to re-interprete their mythical Reverso model from 1931 to celebrate its 80th anniversary, the result was beyond expectations. Sculpted in platinum, the legendary Art Deco case has been enlarged  to house the Gyrotourbillon 2. Composed of 371 parts and 58 jewels, the present model goes beyond limits already achieved with the 1st edition of the Gyrotourbillon 1 developed by genius watchmaker Eric Coudray. While the Gyrotourbillon 1 is beating at 21'600 alternances per hour, the present Gyrotourbillon 2 is impressively calibrated for 28'800 alternances per hour. Never seen on a wristwatch previously, the cylindrical spring allows a more regular and constant deployment than a flat spring as the energy contained is spread more evenly.

The speed of the revolving cage was enhanced to gain more precision and to even up all the possible loss of time due to the various cage positions. The outer cage makes one revolution every 60 seconds, while the inner one at a rate of 18.75 seconds. Another mechanical prowess is the single barrel offering 50-hour power reserve to this technical marvel.  To increase the pleasure of the wearer, the fully skeletonized dial and case back reveal the exquisitely designed and crafted movement. 80 years after the launch of the Reverso, this variation represents an elegant and sophisticated response to the technical challenge of a tourbillon with cylindrical balance wheels and has become a state-of-the art model which is now part of the collection called "horological excellence".
