Let Us Review The Jaeger-LeCoultre Duomètre Sphérotourbillon With 42mm Case Replica

As we approach the opening of the 2017 SIHH Replica Watch In Discount salon in Geneva on January 16, we take a sneak peek at three new replica watches from Jaeger-LeCoultre’s Duomètre collection, all graced with new, gray magnetite, opaline-finish dials: the Duomètre Sphérotourbillon, Duomètre Chronograph, and Duomètre Quantième Lunaire.

The Jaeger-LeCoultre Duomètre Sphérotourbillon Replica has a 42-mm case made of 18k rose gold. Its manual-wind tourbillon movement, Caliber 382, is hand-made and decorated entirely in-house at the brand’s manufacture in the Swiss Vallée de Joux. Like all Duomètre calibers, it follows JLC’s “dual-wing” concept, in which the supply of power to the movement is independent of the supply fed to the additional complications. In the case of this replica watch, the system allows for a tourbillon with a dedicated seconds display that can be stopped at will. A push-piece at 2 o’clock allows the user to reset the seconds to zero, via a flyback mechanism, without simultaneously halting the regulating organ — which helps the replica watch to retain maximum precision. The tourbillon cage, made of titanium and positioned in the cutaway dial at 9 o’clock, makes a three-dimensional rotation and thus requires an additional axis. The combination of these speedy rotations (30 seconds for the cage, 15 seconds for the axis) helps defy the effects of gravity by compensating for various wrist positions. The movement also features a cylindrical balance spring with two terminal curves (a hallmark of the original Sphérotourbillon) and a frequency of 21,600 vph.

The dual-wing concept is reflected in the dial design, with the main dial, with local time and date, positioned to the right of the large opening for the Sphérotourbillon. The small seconds subdial appears in the lower part of the dial, while a 24-hour subdial indicating a second time zone is placed in the upper part.  Two separate power-reserve indicators, one for the movement, one for the indications, appear near the top and bottom. The magnetite gray dial is enhanced with leaf-shaped, gold-plated hands and rose-gold appliqués; the replica watch is mounted on a brown, hand-sewn alligator strap.

In the Duomètre Chronograph, powered by Caliber 380, the dual-wing concept devotes one gear train to the timekeeping — hours, minutes, seconds, with chronometer-level precision — and the other to the chronograph, which has a 1/6-second jumping seconds feature. Each function is powered by its own barrel offering a power reserve of 50 hours (50 for the time, 50 for the chronograph), with no transfer of energy between the barrels. Both barrels are wound by a single crown: turning the crown clockwise winds the main movement for the time, and turning it counterclockwise winds the chronograph. The replica watch, which has a rose gold, 42-mm case with polished and satin-brushed finishes, is the first chronograph wristreplica watch to operate without a coupling system; a single push-piece, located above the crown, controls all the start, stop, and reset functions.

If you wanted a single, crystal clear example of how far Jaeger-LeCoultre’s watchmaking – and complicated watchmaking in general – has developed in the past decade, in both science and craft, then this could be it.

It was only eight years ago, in 2008, that Jaeger-LeCoultre replica watch brought out what stands as one of the great achievements in modern horology: Gyrotourbillon 2, a spectacularly extravagant two-axis tourbillon wristwatch in a swivelling Reverso case. It came four years after Jaeger’s first Gyrotourbillon replica watch.

The new Jaeger-LeCoultre Classic Reverso Tribute Gyrotourbillon replica watch is still big, of course, but with a reported 30 percent less mass than its predecessor, and a new case shape that curves gently around your wrist, it is genuinely an easy enough watch to wear. And what you see when you do, dazzles. The fact that it’s too tall to slide under a cuff like most Reversos is rather fitting: this Reverso deserves to be seen.

Rather than call this Gyrotourbillon 4, Jaeger-LeCoultre has named the new Jaeger-LeCoultre Classic Reverso Tribute Gyrotourbillon replica watch simply the Reverso Tribute Gyrotourbillon – which emphasises the fact that, in keeping with the other Tribute models unveiled this year, this is a dual face, dual time zone Reverso.

A single movement with two independent dials either side of it is a complex enough undertaking – but in a watch with a three-dimensional tourbillon, plus a day-night indicator, that takes up 30 percent less space than its predecessor, it’s more than a little remarkable.

Swivel the Jaeger-LeCoultre Classic Reverso Tribute Gyrotourbillon replica watch case, and you’re greeted with a complex swirl of skeletonised and engraved bridges, with a second time zone dial and a 24-hour day/night display at 2 o’clock, opposite that on the other side. The inside of the case is engraved with a sunburst of its own, with a smooth, polished centre circle to act as background to the tourbillon. True theatre for the wrist.
