Duomètre

Born from the dream to push the boundaries of watchmaking, the Jaeger-LeCoultre Duomètre's Dual-Wing concept is doubly revolutionary. Two independent mechanisms, united by a single regulating organ, guarantee the unparalleled performance and precision of a Duomètre watch. The first mechanism is dedicated to the proper functioning of the complications, The second ensures the precise measurement of passing time.
