The Duomètre à Quantième Lunaire incorporates Jaeger-LeCoultre”s latest horological achievements: it displays time with a jumping seconds hand – the so-called "Seconde Foudroyante" – showing 1/6th of a second increments and additionally providing the date and the age of the moon in a separate sub dial. But the truly novel aspect of this watch lies in the Dual-Wing movement concept, which features two independent power supplies: one dedicated to timing – regulated by escapement and balance, and the other for the display of time – hour, minute and seconds hands, plus the 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.

The driving force behind the design is timekeeping accuracy. The Dual-Wing concept addresses an age-old problem in watchmaking: every complication reduces the amount and consistency of the energy reaching the escapement. The more regular the energy flowing to the going train and escapement, the better the chances for highly precise timekeeping.
