Duomètre à Quantième Lunaire

The Duomètre line gets a new member: the Quantième Lunaire shows time, date and the age of the moon with the unprecedented precision of the ingenious Dual-Wing-movement concept.

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.

The new Jaeger-LeCoultre Calibre 381 is executed and decorated with distinguishing decors for the corresponding parts of each function of the movement. These fine details can be appreciated through the sapphire case back of the wristwatch, visually in accordance with the typical Duomètre-design: classical and understated with a touch of extravagance. Even though the watchcase houses a complex movement, its open worked dial provides clarity and ensures easy reading by being divided into two sections according to their functions: Hour and minute on the right hand side, date and moon phase on the left hand side, a central seconds hand and the jumping seconds in the lower middle of the watch.

The Duomètre à Quantième Lunaire will be produced in a limited edition of 200 white gold watches. With the new Duomètre à Quantième Lunaire, the watchmakers of Jaeger-LeCoultre are setting standards in the world of haute horlogerie by pushing precision to new heights.
