Jaeger-LeCoultre Duomètre Quantième Lunaire Now In Steel

Jaeger-LeCoultre Duomètre Quantième Lunaire (Moon Phase), is the first Duomètre piece to be offered in steel.

The eye-catching blue dial, paired with a new case, lends a decidedly contemporary air to a timeless and distinctive design. Emphasising the precision of the calibre, a distinctive element of the Duomètre Quantième Lunaire dial is the seconde foudroyante hand, which whirls continuously in a sub-dial at 6 o’clock. Making a complete revolution in one second (versus a ‘standard’ seconds hand, which rotates in 60 seconds) with six ‘jumps’ per rotation, the foudroyante hand makes it possible to observe intervals of precisely one-sixth of a second.

For Jaeger-LeCoultre, the pursuit of precision is not limited to the accuracy of timekeeping but is equally important for the beauty of the design and finishes. On the deep blue dial of the Duomètre Quantième Lunaire, the long and very fine hands are a signature of all Duomètre watches, as is the symmetrical layout, with three sub-dials forming an inverted pyramid. The sub-dial at 3 o’clock shows the time, with the cardinal hours marked by applied Arabic numerals; the sub-dial at 9 o’clock displays the date with a hand and the moon phase set against a blue sky. The seconde foudroyante sub-dial nestles beneath them at 6 o’clock.

The dial is made in several sections, with different finishes to create visual interest and contrast. The opaline main dial has the very soft glow and sense of visual depth characteristic of that decorative technique. The lower section of the dial is sunray-brushed and, in an added touch of refinement, the two power reserve indicators are distinguished from this sunrayed background by an opaline arc.

Inspired by the aesthetic of the sector dials that were featured on historic timepieces, the broad ring encircling each The convex curve of the dial perimeter closely follows the contour of the glass -box crystal that protects it, and the sub-dials are slightly sunken into its surface, increasing the sense of visual depth.

Jaeger-LeCoultre has designed an entirely new case for the collection. A contemporary interpretation of the savonette pocket watches created by the Maison in the 19th-century, its rounded contours are highly tactile as well as visually appealing. (The French word savonette literally means a small disc of soap with rounded contours that can be cradled in the palm of a hand). With its convex crystal and gracefully rounded bezel, the new Duomètre case expresses this literal definition very well.

With its blue dial and steel case, the new interpretation of the Duomètre Quantième Lunaire lends a decidedly contemporary air to a technically sophisticated timepiece. It perfectly represents Jaeger-LeCoultre’s relentless pursuit of precision and its spirit of innovation, anchored in a deep respect for the traditions of Haute Horlogerie.
