Sonata Cathedral Dual Time

    The Sonata Cathedral Dual Time is an in-house development, inspired by Dr. Ludwig Oechslin, constructed by Pierre Gygax and Lucas Humair, and executed by the Ulysse Nardin team led by Rolf Schnyder. The engineers and technicians spent nearly seven years on the development of this patented self-winding manufacture caliber. It combines a novel alarm setting with a countdown indicator and the dual-time system with the instant time-zone adjustor featured in many Ulysse Nardin watches. Inside Information: Dr. Ludwig Oechslin is the curator of the world-famous watch museum in La Chaux-de-Fonds, Switzerland.
