The Duomètre à Quantième Lunaire embodies the latest in horological achievements of Jaeger-LeCoultre: it displays time with a jumping seconds hand showing 1/6th of a second increments and additionally providing the date and the age of the moon in a separate sub dial. The true genius of this watch however lies within the Dual-Wing movement concept, which features two independent power supplies: one entirely dedicated to creating a perfect timing foundation – regulated by escapement and balance –, the other solely for the display of time – hour, minute and seconds hands – as well as date and the age of the moon for the Northern as well as the Southern hemisphere. Both are synchronized through the jumping seconds hand mechanism driven by the escapement. With the Duomètre line, Jaeger-LeCoultre breaks new ground in terms of the accuracy of mechanical wristwatches, for it devised a completely new movement structure in order to gain the highest possible precision. Therefore the watchmakers have come up with the so called Dual-Wing concept to bypass a common problem in mechanical watches: any additional complication reduces the power of the winding barrel thus depriving the precisely tuned regulation organ of a steady flow of energy from the winding barrel. The regularity of the winding barrel’s energy to the going train and escapement remains of primary importance in order to measure time with the precision demanded for today’s mechanical wristwatches.
Since 1833, when the inventive Charles Antoine LeCoultre established this venerable watchmaker, it has produced some of the most outstanding and innovative timepieces. It wasn't until 1931, however, that the Jaeger-LeCoultre brand rose to international fame. It was then that the Reverso - an ingenious reversible watch - was unveiled to the public.
