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.
