The result of many years of research by Jaeger-LeCoultre, this watch incorporates the latest progress in the area of sound. Faithful to the spirit of the new Grande Tradition collection, its mechanical calibre in nickel-silver, with a power reserve of two weeks, entirely decorated by hand, once again reflects the Grande Maison’s watchmaking artistry. Only available in a limited series of 100 timepieces in 18-carat yellow gold.
