Lot Essay
Made in a limited edition of 75 pieces in 2008 for the 175th Birthday of Jaeger-LeCoultre and to commemorate the 80th Birthday of the Reverso model, the ultra-sophisticated Reverso Gyrotourbillon 2 has been described as “one of the most remarkable achievements in contemporary haute horology”. The present watch is number 66 of this edition.
Housed in an enlarged version of Jaeger’s iconic ‘Art-Deco’ Reverso case and visible from both sides, the extraordinary 3-dimensional Gyrotourbillon 2 manual winding caliber JLC 174 movement is a ‘living’ miniature sculpture. The action of the inclined two-cage spherical tourbillon turning on two axes is both mesmerizing and incredibly beautiful in its conception. The twin openworked dials display the hours and minutes with the seconds on the tourbillon carriage on one side, the power reserve and 24-hour indication on the other.
Jaeger-LeCoultre first introduced their two-axis ‘Gyrotourbillon’ in 2004, the ‘Gyrotourbillon 1’ which was developed by master watchmaker Eric Coudray. The present platinum version, reference 23.36.42.0, the ‘Reverso Gyrotourbillon 2’ was its successor, launched in 2008. It was awarded the “Complicated Watch Prize” at the Grand Prix d’Horlogerie de Genève in the same year.
The Jaeger-LeCoultre Reverso Gyrotourbillon 2 – The Multi-Axis Tourbillon
Composed of 371 parts and 58 jewels, 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.
