Jaeger-LeCoultre presents Duomètre Sphérotourbillon, Duomètre Chronographe and Duomètre Quantième Lunaire, three striking interpretations of the Duomètre line.
The famous Duomètre line now gets three new interpretations, all in dials of magnetite grey with an opaline finish. Moreover, all of these feature the famous Dual-Wing concept. But, there is more to it. Read on….
Jaeger -Lecoultre Duomètre Line
Exceptional precision. Well, that’s what aptly describes this watch. Using the Dual-Wing concept has enabled Jaeger-LeCoultre’s watchmakers to create a tourbillon with precision adjustment. The small seconds can be reset to zero according to the flyback principle by using a push-piece located under the tourbillon at 2 o’clock. A particular feature of the 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, accurate to one second, even while the time is being set.
A multi-axis tourbillon is another striking feature. A fascinating spectacle is revealed by the cut-away dial as the tourbillon completes a rotating motion that is highly unusual in nature. 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.
A transparent case-back provides an admirable “backstage” view of the workings of the hand-assembled and decorated movement, Jaeger-LeCoultre Calibre 382. A sophisticated pink gold case, a plain and readable dial, polished lugs and bezel, and a satin-brushed case middle add to the elegant aesthetics of the watch.
Here again, in order to gain maximum precision, the watchmaker wanted to make a chronograph watch as accurate as a chronometer. Hence, they have used the Dual-Wing concept.
In accordance with the Dual-Wing concept, the first gear train is entirely dedicated to the time function (hours, minutes, seconds), while the second gear train is exclusively devoted to the chronograph function and features a 1/6th second jumping seconds.
This Calibre 380 makes the first Duomètre the very first wrist chronograph watch to operate without a coupling system to handle the stop/start time measurement functions. A single push-piece ensures perfect synchronisation of all five chronograph counters.
Duomètre Quantième Lunaire
The Dual-Wing concept has also been applied in the calendar watch.
Arranged on the elegant and easily readable dial, the hours, minutes, seconds, calendar, and moon-phase displays appear to make the Duomètre Quantième Lunaire a conventional timepiece. But inside the case and partially hidden from view beats Calibre 381, a prodigious movement boasting unprecedented precision based on the Dual-Wing concept, which propels the watch firmly into the spheres of fine watchmaking.
With its Duomètre line and its Dual-Wing concept, Jaeger-LeCoultre plays a pioneering role in the field of fine watchmaking by creating a movement with an entirely innovative structure, giving rise to unprecedented functions!
