OVERVIEW
REVOLUTIONARY APPROACH TO PRECISION
A magnificent reinterpretation of the Quantieme Lunaire watch. The first Duometre piece to be offered in steel, its eye-catching blue dial, paired with a new case, lends a decidedly contemporary air to a timeless and distinctive design.
MECHANISM
THE ESSENCE OF INVENTIVENESS
Introduced in 2007, the patented Duometre mechanism features two barrels and two separate gear trains linked to a single regulating organ. One gear train powers the time and the other drives additional functions, guaranteeing exceptionally high degree of operating accuracy.
DESIGN
PRECISE APPROACH TO AESTHETICS
The pursuit of precision is equally important for the beauty and finishes. On the deep blue dial of the Duometre Quantieme Lunaire watch, the long and very fine hands are a signature of all Duometre timepieces, as is the symmetrical layout, with three sub-dials forming an inverted pyramid. The counters show the time, the date and a beautiful moon phase set against a blue sky.
CHALLENGING DECORATIVE FINISHES
The approach to precision can further be seen in the finishing of the movement, visible beneath the crystal case-back. Demanding absolute precision, each bridge is decorated one-by-one with Sunrayed Geneva stripes, creating visual unity across the entire expanse of the movement.
REFINED OPALIN & SUNRAY-BRUSHED DIAL
Creating visual interest and contrast, the dial echoes traditional aesthetics featuring three distinctive counters. The opaline main dial has the very soft glow, while the lower section of the dial is sunray-brushed and the two power reserve indicators are distinguished by an opaline arc.
BRUSHED, POLISHED & MICROBLASTED CASE
The case is a complex structure of more than 30 separate parts and the lugs are screwed rather than integrated to enable the use of multiple finishing techniques. A mixture of polished, brushed and micro-blasted surfaces creates a fascinating play of light with every movement of the wrist.
CALIBRE
THE CELESTIAL COMPLICATION
Calibre 381 incorporates the Duometre concept with one gear train for timekeeping and the second gear train for the complication. Featuring a moon-phase display, two power reserve indicators, it also displays a seconde foudroyante whirling continuously, a signature twist of this model.
CALIBRE
MADE IN OUR MANUFACTURE
From its calibre to its case, every Jaeger‑LeCoultre luxury watch is designed, manufactured and assembled under one roof, at our Manufacture in the Vallee de Joux. Our obsession with quality is renowned as every Jaeger‑LeCoultre model undergoes strict “1,000 Hour Control” testing. This unique program provides internal certification tests that far exceed official chronometry tests.
It includes movement testing before and after casing and extends throughout assembly, according to conditions that match daily wear. A quality seal is engraved on the back of every watch once it meets our strict standards.
OUR NOVELTIES
