Key Facts :
- Duometre: a revolutionary approach to timekeeping precision
- The first Duometre model in steel – and a new case designn
- A deep blue dial distinguished by multiple decorative finishes
Since the launch of the Duometre Chronograph in 2007 – the first timepiece based on the ground-breaking Duometre concept – the system has been used with a few other complications, giving its name to a line of technically advanced watches that are distinguished by highly precise timekeeping.

Ensuring a Perfect Supply of Energy
With their invention of the Duometre in 2007, Jaeger-LeCoultre’s engineers and watchmakers solved a fundamental problem of complex mechanical watches. That is, to operate, a complication must draw from the energy that is supplied from the barrel to the escapement via the gear train. This naturally interrupts the perfect regularity of the power supply and thus compromises precision.

A Precise Approach to Aesthetics
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 Duometre Quantieme Lunaire, the long and very fine hands are a signature of all Duometre 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 is sunray-brushed. 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.

Further evidence of the Maison’s approach to precision can be seen in the finishing of the movement, fully visible beneath the transparent crystal case-back. Much of the calibre is open-worked, which serves both an aesthetic and a technical purpose: the latter enables the watchmakers to set and assemble some of the 374 components more easily, while the former allows a view deep into the mechanism.

Creating visual unity across the entire expanse of the movement, the bridges are decorated with sunrayed Geneva stripes. It’s a challenging technique that demands absolute precision because the components must be decorated one-by-one, yet the stripes must radiate from the centre of the regulating organ to the edge of the calibre in perfect alignment once the movement is assembled.
A New Duometre Case: Contemporary Elegance Inspired by Tradition
Marking the launch of three new Duometre models in 2024, 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 Duometre case expresses this literal definition very well. The crown, too, has been redesigned, with deep and rounded notches that make it a joy to handle. Indeed, the only sharp lines to be found are on the highly polished edges of the lugs.

A comfortable 42.5 mm in diameter, the case is a complex structure of 34 separate parts and the lugs are screwed rather than integrated, to enable multiple finishing techniques. A mixture of polished, brushed and micro-blasted surfaces creates a fascinating play of light with every movement of the wrist.

With its blue dial and steel case, the new interpretation of the Duometre Quantieme 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.
