Jaeger-LeCoultre Duometre Quantiéme Lumiere

Equipped with the revolutionary ‘Dual-Wing’ concept, it guarantees incomparable precision-timing performances for a watch with complications. Two separate barrels supply energy to two separate hour-minute and moon-phase calendar mechanisms. The jumping stop seconds system ensures accuracy of up to 1/6th of a second when setting the time piece. Finally, the calendar serves to display the day, date, month as well as the age of the moon.
