Jaeger-LeCoultre_Duometre_Quantieme_Lunaire_01

There are many distinct combinations of complications available in the horology market, but still this Jaeger-LeCoultre creation manages to be quite unique. The “Duomètre” was conceived with a doubly revolutionary concept of uniting two independent mechanisms by a single regulating organ, for an unequaled level of performance accuracy and quality.

SIHH 2016 saw many new releases by Jaeger-LeCoultre, like a series of their Reverso’s, which were celebrating their own 85th anniversary, as one of the brands best-selling watches. They also released a revamped version of their “Geophysics” model line, with extreme weather conditions in mind. This already impressive timepiece, returned in this “Geophysics Universal Time” form attempting to gain the title of quintessential world-time traveler watch.

As for this new “Jaeger-Lecoultre Duomètre à Quantième Lunaire” the 40mm case is made of white gold, which is one of the novelties Jaeger-LeCoultre has brought to this model line in 2016. There’s a screw-in crown and a pusher near where the typical 10 o’clock position would be, that serves to adjust the date. The pusher is an actual pushable button, instead of an inset pusher, which provides a more tactile, audible and memorable interaction. It could be an issue for people afflicted by OCD (Obsessive Compulsive Disorder) but keeping a positive outlook, it can also benefit more watchmakers in the long run. But, yet again, jokes aside, Jaeger-LeCoultre has really delved into details on this timepiece.

The “Duomètre” which can translate to “Dual-Wing” is a concept system based on having a single movement being separate from the one telling time and the other complications going on. That’s why it includes: two barrels and two gear trains being both regulated by a single escapement module. And thanks to this “Dual-Wing” concept, the watch can display time with the accuracy of a chronometer. Also the Jaeger-LeCoultre 380 caliber movement is the first movement not to use a coupling system. A single crown is used to wind the watch and the chronograph. In one direction it winds the watch and in the opposite direction it winds the chronograph (watch video below for visual assistance) and both winds have a power reserve of 50 hours.

For this new “JLC Duomètre à Quantième Lunaire” version, the first gear is exclusively assuring accuracy and its second gear train (which on previous versions regulated the chronograph function) is dedicated exclusively to the hour, minutes, seconds, calendar and lunar calendar. It’s this co-existence of the two halves of the trademark “Dual-Wing” movement: allowing one mechanism to ensure the correct operation of the watch’s complications; while the other ensures the accuracy of its timekeeping. That truly makes it stand-out amongst other complicated timepieces, without doubting its reliability.

Revisions on the predominantly silvered opaline dial were quite significant, as elements were removed and shifted positions to allow a view at the inner hand-wound movement. JLC have also added a more aesthetically pleasing moonphase disc, with blue and gold highlights to appear more realistic. A laser technique is utilized to provide the moons and stars with a more textured look, versus simply polished circles. There are three off-set sub-dials: on the right-side there’s the hour-counter with two yellow gold hands and baton hour index markers; To the left-side is a calendar with black Arabic numerals, except the number “31” in red; and there’s also a finely detailed hand-hammered moonphase in its midst, with sparkling stars.

Towards the 6 o’clock position are the ‘jumping seconds’ from one to six, leaping over 10-second intervals at a time. And to each side of these sub-seconds is a power reserve indicator. Counting down 50 hours for each of the functioning wind-ups.
