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 Jaeger-LeCoultre Reverso Gyrotourbillon 2 – The Multi-Axis Tourbillon
The Gyrotourbillon 2 incorporates several technical advances including beating at 28,800 alternances per hour instead of the 21,600 beats of the Gyrotourbillon 1. However, the chief feature is the spherical tourbillon itself, the rotation of which is extremely unusual. The tourbillon is quite spectacular to watch in action and is so precise that it enabled Jaeger-LeCoultre to win a prize the first official timing competition of the 21st century. The carriage itself is machined from a single block of titanium, in addition to the tourbillon revolving around the axis of its titanium carriage, it also rotates around a second axis, inclined at a 20° angle. The combined effect of these two rotations (respectively 30 and 15 seconds per revolution) frees the watch from the effects of gravity and also results in it being extremely lightweight and of very high precision. Another important feature is the cylindrical balance spring with two terminal curves, although patented in 1782 by the Englishman, John Arnold, this is the first time that the cylindrical balance spring had been miniaturized for use in a wristwatch. The cylindrical shape serves to make the movement more isochronous, the two terminal curves giving a more even motion during each rotation.
