Zenith is known for its daring and innovations in watchmaking. The history of Zenith started in 1865 when Georges Favre-Jacot created a new concept of manufacturing watches in Le Locle, Switzerland. The first automatic chronograph, the legendary El Primero with 36,000 vibrations per hour, was developed by Zenith, and it is still the world’s most precise series-made chronograph caliber.
