Ulysse Nardin is a watch manufacturer founded in 1846 in Le Locle, Switzerland. Historically Ulysse Nardin was best known for being a manufacturer of marine chronometers, but today Ulysse Nardin produces complicated mechanical watches. Founder, watchmaker Ulysse Nardin, was an accomplished watchmaker who studied horology under his father, Leonard-Frederic Nardin, Frederic William Dubois, and Louis Jean Richard-dit-Bressel, in Switzerland.  Before the advent of quartz timepieces, merchant and military ships relied on highly accurate mechanical timepieces known as marine chronometers. The best known of these was the M,GR.F model by Ulysse Nardin. Of the 4,504 certificates for marine chronometers issued 4,324 were issued to Ulysse Nardin.

In 1983, Ulysse Nardin was acquired by businessman Rolf Schnyder who, in conjunction with watchmaker Ludwig Oechslin, relaunched the brand with other investors. Schnyder, Oechslin and the staff of Ulysse Nardin, design and create complication timepieces using modern materials and manufacturing techniques. Among the most reliable ever made, Ulysse Nardin's marine chronometers are still sought by collectors around the world. Ulysse Nardin continues to be in the forefront of watchmaking technology by pioneering new materials in manufacturing high precision movement components and most innovative timepieces.
