 Line a Swiss watch.jpg "calibre 381") company Jaeger-LeCoultre «Duomètre» welcomes a new model Duomètre a Quantième Lunaire, which appear on the face of time, calendar and moon phases. All of this sets in motion a stunning mechanism with unprecedented precision, based on the concept of Dual-Wing (double wing).
Duomètre à Quantième Lunaire embody the latest achievements in watchmaking house Jaeger-LeCoultre: they display while jumping arrows showing a step of 1 / 6 second increase and, in addition, provide the date and age of the moon in a separate additional dial. The true genius of these watches, however, is hidden from the eyes of a movement such as Dual-Wing, the concept of which includes two independent power supply, one completely given over to creating an ideal source of energy of motion, it is equipped with an adjustable escapement and balance, while the other, exclusively for transmission and display - hour, minute and second hands - as well as date and age of the moon in both the northern and southern hemisphere. Both parts of the Dual-Wing mechanism synchronized with the hopping movement of the second hand, based on the trigger device.
With the release of the line Duomètre Jaeger-LeCoultre has opened up new horizons in the watchmaking world in terms of the accuracy of mechanical watches designed for them a completely new structure of the mechanism to achieve the greatest possible accuracy. So watch the engineers of the company Jaeger-LeCoultre invented the so-called mechanism Dual - Wing, the concept of going around a common problem in all mechanical watches: any further reduce power consumption of the helix rim balancing, thereby depriving the finely tuned regulator continuous flow of energy transmitted from the mechanism the balance sheet. The power supply of balancing on the rim rappel device is of paramount importance in order to measure time with the accuracy required for mechanical watches today's world.
Consequently, the influence of a .jpg "calibre 380") complication of these watches with a lot of progress could lead to deviations in the time dimension, which is hardly acceptable in watches of premium class. This fact can be overcome by using a completely independent power supply for operation complication, separate from the rim balancing, feeding energy into the basic mechanism which, in turn, feeds on its winding spiral, thus ensuring a constant flow of energy to trigger the device. Therefore, the concept of Dual Wing, first introduced by Jaeger-LeCoultre watches in Duomètre à Chronographe in 2007, is now included in the new line Duomètre à Quantième Lunaire, which led to a tremendous increase in the accuracy of the complicated mechanical watches with additional devices.
Such attention to detail suggests that the experts from Jaeger-LeCoultre, developing a mechanism based on the Dual-Wing clock-calendar with exceptional qualities, have reached a level of accuracy, which still could be achieved only on the clock with no complications. Such a complex approach to chronometric precision-typical example of the advantages gained over 177 years of high horology.
The new men's watches Jaeger-LeCoultre caliber 381 are made and decorated with a distinctive decoration for the relevant parts of each details of the mechanism. These beautifully hand-processed parts can be evaluated through sapphire inserts on the back of the watch, visually distinguishable feature which is typical for Duomètre design: classic and understated silhouette with a touch of extravagance. Although the watch case contains enough sophisticated mechanism, its large open face provides clarity and ease of reading, being divided into two parts according to their functions: hours and minutes on the right side, date and moon phase on the left side, and the central seconds hand and hopping seconds in the lower mid-hours.
Chronometers Jaeger-LeCoultre Duomètre à Quantième Lunaire will be released in limited edition of 300 copies in the case of yellow gold and unbounded in the series with the clock in case of pink gold. With the new Duomètre à Quantième Lunaire Jaeger-LeCoultre watchmakers are setting new standards in the world of Haute Horlogerie, raising the bar for accuracy to new heights.
Movement of Dual-Wing - another concept of timing.
 Since its founding brand Jaeger-LeCoultre 177 years ago, the desire for accuracy and reliability have been the driving force and inspiration for the efforts of watchmakers from Jaeger-LeCoultre. With each new invention, the production was based on the embedded new know-how gained during the development and manufacture of some of the most striking movements in the history of Swiss watchmaking: Gyrotourbillon I spherical tourbillon with a specific; Master Minute Repeater with its unique sound system; Reverso Grande Complication à triptyque-the most sophisticated rotary clock; Master Compressor Extreme LAB-first hours, working completely without lubrication and Hybris Mechanica à Grande Sonnerie-hours with the longest battle of all time. These vertices are always guaranteed the genius of watchmaking manufacture Jaeger-LeCoultre brand leader in the history books of the Swiss watch industry.
For newly designed mechanism Dual-Wing Jaeger-LeCoultre has once again left the beaten path of modernization in order to invent an entirely new mechanism, aimed at addressing the accuracy of mechanical watches with complications. In a conventional wristwatch complexity of any function is not constant counterweight attached to the rim and take the energy in the event of activation, thereby altering the constant energy supplied to the primary mechanism for the timing: Chronograph, as he is on, relay in a time when it rings, or even function calendar included only once a day in traffic management - each of these devices leads to a drop in the amplitude of oscillation of the pendulum and the deviation in the accuracy of stroke, because they absorb more power for their own functioning. Those changes in the amplitude, summed over weeks, lead to intolerable inaccuracies in the measurement of time.
To circumvent this problem, Duomètre watch is equipped with two independent watch movements in the same caliber, one works for the measurement of time and energy to produce other complications. Both the generating mechanism of synchronized hopping mechanism through the second hand, so-called "Seconde Foudroyante". This general regulatory body provides a continuous decent chronometer accuracy, even if the complication is introduced into the mesh gear to get the necessary energy.
In 2007, Jaeger-LeCoultre company was put into production chronograph Duomètre à Chronographe within the first few hours in line Duomètre. Being among the first hours with a completely new mechanism of movement, built over the last 160 years, they were awarded the prestigious world awards for its unique concept.
With the new Duomètre Lunaire à Quantième company is date-moon-complexity concepts Dual-Wing. The movement shows hours, minutes, seconds, leap second second hand, date and age of the moon for the Northern and Southern hemispheres. Although housing Duomètre à Quantième Lunaire, contains an extremely complex gauge with two mechanisms, and more than 369 parts, it combines the readability and style.
