Including the Duomètre Héliotourbillon Perpetual, featuring a “spinning top” effect that is a first for the watchmaker.

At this year’s Watches & Watches in Geneva, Jaeger-LeCoultre has introduced a stunning lineup of timepieces that includes the enchanting Duomètre Chronograph Moon, seamlessly integrating a high-precision chronograph with a moon phase display; the sophisticated Duomètre Quantième Lunaire, now reimagined in steel with a captivating deep blue dial and the Duomètre Héliotourbillon Perpetual, featuring an innovative three-axis tourbillon alongside a comprehensive perpetual calendar. Each model embodies the Maison’s relentless pursuit of combining advanced mechanical functionality with aesthetic perfection.
Duometre Chronograph Moon
Kicking things off, Jaeger-LeCoultre has unveiled its Duomètre Chronograph Moon. This innovative timepiece marries the precision of a chronograph with the poetic display of moon phases, showcasing the brand’s mastery in combining technical complexity with aesthetic elegance. Powered by the newly developed Calibre 391, the watch features a unique dual-wing mechanism, ensuring that the energy consumption of its complications does not compromise its timekeeping accuracy. This cutting-edge model comes in two exquisite variations: one with a platinum case and copper-colored dial and the other in pink gold complemented by a silver dial, both attached to a sophisticated hand-stitched alligator strap.
The watch boasts a manually wound mono-pusher chronograph, a moon phase and night-day complication, alongside two power reserve indicators, all enclosed in a newly designed case that nods to the brand’s 19th-century savonette pocket watches. The openworked dial and movement, visible through the transparent case-back, highlight the meticulous craftsmanship and attention to detail synonymous with Jaeger-LeCoultre, blending traditional finishes with modern elegance.
Duometre Heliotourbillon Perpetual
Also in the lineup is the Duomètre Héliotourbillon Perpetual, a stunning fusion of advanced mechanics and elegant design. At the heart of this timepiece lies the new manual Calibre 388, developed entirely in-house, featuring an unprecedented tourbillon that rotates on three axes to produce a captivating “spinning top” effect — a first for the Maison. This mechanical marvel, which beats at a frequency of 4Hz, is enhanced by a perpetual calendar with a grande date display that showcases the brand’s dedication to combining precision with sophisticated complications.
The Duomètre Héliotourbillon Perpetual features a unique tourbillon mechanism, constructed with three titanium cages, weighing less than 0.7 grams and displays nearly eight decades of Jaeger-LeCoultre’s tourbillon expertise. This innovative design significantly improves the watch’s accuracy by compensating for gravitational effects in all positions. The addition of a perpetual calendar, which requires manual adjustment only in 2100 and not in leap years, underscores the complexity and functionality of the Calibre 388. Additionally, the refined dial design features a new arrangement that turns the traditional Duomètre layout by 90 degrees and includes a grande date display, complementing the watch’s advanced mechanics with an equally sophisticated aesthetic.
Encased in a newly designed pink gold case that reflects a modern interpretation of the 19th-century savonette pocket watches, the Duomètre Héliotourbillon Perpetual marries traditional elegance with contemporary innovation. The case’s complex structure, consisting of 34 parts with a blend of polished, brushed and micro-blasted surfaces, enhances the visual appeal and complements the intricate movement within.
Duometre Quantieme Lunaire
Featuring a slightly more modern design, the Duomètre Quantième Lunaire marks a significant evolution within its series, which is renowned for uniting technical innovation with precision. Launched in 2024, this latest rendition stands out as the first Duomètre model to be crafted in steel as it introduces a contemporary twist to its classical aesthetics with a striking blue dial and redesigned case. This model emphasizes the Maison’s commitment to precision as well as underscores a modern approach to watch design. The Duomètre’s dual-wing system is designed to ensure utmost accuracy by segregating the power supply to the timekeeping functions and the complications, in so doing, maintaining consistent energy flow and precision irrespective of the complications’ operation.
The aesthetic appeal of the Duomètre Quantième Lunaire is matched by its technical prowess, featuring a manually wound Calibre 381 that showcases Jaeger-LeCoultre’s mastery in watchmaking. The deep blue opaline dial, adorned with various decorative finishes and the innovative seconde foudroyante display, allows for the measurement of time in precise one-sixth-of-a-second intervals. As for design, the watch reflects a meticulous approach, from the symmetrical layout of its sub-dials to the sunray-brushed and opaline finishes that create a play of light and depth.
