Zenith was founded in 1865 in Le Locle, Switzerland by Georges Favre-Jacot. This Swiss watchmaker is arguably best known for its iconic El Primero movement, introduced in 1969. Zenith was so respected for this movement that, from 1988 - 2000, Rolex leveraged a version of it in their Daytona models. Zenith is currently owned by the luxury conglomerate, LVMH, headed by Bernard Arnaut.
