Ulysse Nardin SA is a Swiss luxury watchmaking company founded in 1846 in Le Locle, Switzerland.
The company became known in the nautical world for manufacturing highly accurate marine chronometers and complicated timepieces used by over fifty of the world's navies from the end of the 19th century till 1950. According to the last official report of Neuchâtel Observatory in Switzerland, Ulysse Nardin had won numerous awards and honors for its marine chronometers from 1846 to 1975, including 4324 certificates, 2411 special prizes and 18 gold medals at International Exhibitions. The company was later taken over and re-invigorated in 1983 by Rolf W. Schnyder who transformed it into a profitable business again. Since 2014, it has been a subsidiary of the French Kering Group. Ulysse Nardin has operated out of the same building headquartered in Le Locle, Switzerland since 1865.
The company today designs and manufactures luxury watches, dual time watches, marine chronometers, and sells its products through a network of distributors and several boutiques around the world.
