Zenith Manufacture was founded in 1865 by Georges Favre-Jacot. He was a pioneer in bringing all watchmaking professions under one single roof. In 1969, the mythical El Primero movement was invented, the first automatic high frequency chronograph able to measure the 1/10th of a second. Representing a rare phenomenon in the watch industry, ZENITH Manufacture is currently still located in the exact same spot where the founder built his first workshop. Chronometry awards: world record. The ZENITH Manufacture has been awarded 2333 chronometry prizes in its century and a half of existence.
