Jaeger-LeCoultre, renowned for its groundbreaking watchmaking innovations, unveils the reinterpretation of the Duometre Quantieme Lunaire, the first of its kind to feature a steel case and a striking blue dial.
The Duometre concept, introduced in 2007, addresses a fundamental issue in complex mechanical watches: the interruption of precision due to complications drawing energy from the same power source as timekeeping. Inspired by 19th-century solutions, Jaeger-LeCoultre engineers developed a revolutionary system separating power sources for timekeeping and complications into two separate barrels. This ensures a constant power supply and impeccable precision.
The Duometre Quantieme Lunaire features a distinctive seconde foudroyante hand in a sub-dial at 6 o’clock, indicating intervals of precisely one-sixth of a second. Its symmetrical layout features three sub-dials forming an inverted pyramid, displaying time, date, and moon phase against a deep blue dial with opaline and sunray-brushed finishes.
The manual wound movement, caliber 381, visible through a transparent case-back, showcases open-worked components and sunrayed Geneva stripes adorning the bridges.
The new Duometre case, inspired by 19th-century savonette pocket watches, exhibits rounded contours and a convex crystal. The 42.5 mm diameter case, made from 34 parts, offers a mix of polished, brushed, and micro-blasted surfaces, creating captivating light effects.
