Duomètre Sphérotourbillon

ref. 6056590

An authentic revolution in the field of Grande Complication models, the Duomètre Sphérotourbillon, stemming from almost 180 years of history and invention unique to Jaeger-LeCoultre, is equipped with an unprecedented multi-axis tourbillon. In addition to the axis of its carriage, the Sphérotourbillon has a second axis inclined at 20° and thereby freeing it from the effects of gravity in all positions. The revolutionary `Dual-Wing` concept featured in Calibre 382 once again paves the way for an original function and makes this exceptional model the first tourbillon watch that is precisely adjustable thanks to the small seconds flyback system.

Using the Dual-Wing concept has enabled the Jaeger-LeCoultre watchmakers to create the first tourbillon with precision adjustment. The small seconds can be reset with a push-piece, according to the flyback principle. A particular feature of flyback is that it does not stop the function of the regulating organ. The small seconds hand is reset, and immediately continues its course. As a result, the watch retains maximum precision even while the time is being set, accurate to one second.

The Sphérotourbillon mechanism created by Jaeger-LeCoultre offers a fascinating phenomenon that can be viewed via the openwork dial. As well as revolving around the axis in its titanium cage, the tourbillon turns around a second axis, tilted at 20°. The combination of these two distinct and rapid rotations (30 and 15 seconds respectively) enables the watch to defy the effects of gravity in all positions.

With its respect for perfect proportions (only 14.1 mm thick and 42 mm in diameter) and for watchmaking design codes, sophisticated case, simple dial with excellent legibility, polished bezel and horns and a satin finish case middle, the aesthetic look unique to the Duomètre line is carefully preserved on this piece and contrasts with the level of complexity of the mechanism it houses.
