Ulysse Nardin is a watch manufacturer founded in 1846 in Le Locle, Switzerland, where its headquarters remain. Historically, the company was best known for being a manufacturer of marine chronometers, but today it 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 company's M,GR.F model. Of the 4,504 certificates for marine chronometers issued, 4,324 were issued to the company (Lucien F Trueb, Watchtime). In 1983, the company was acquired by businessman Rolf Schnyder who, in conjunction with watchmaker Ludwig Oechslin, relaunched the brand with other investors.
