Ulysse Nardin is a Swiss watch manufacturer founded in Le Locle in 1846, historically the leading maker of marine chronometers for the world's navies. Its principal collections are the Freak, Marine, Diver, Blast and Executive. The maison pioneered silicon components in series watchmaking with the Freak in 2001 - a watch with no dial, no hands and no conventional crown, in which the entire movement rotates to tell the time. Ulysse Nardin returned to independent ownership in 2022 through a management buyout from Kering.
