ZENITH
The watch manufacture Zenith was founded in 1865 by Georges Favre-Jacot. In 1911 the name was changed into „Fabrique des Billodes“. One day Georges Favre-Jacot finished a new movement which he named after the sky and the stars: Zenith. This is how the brand Zenith was born. 1969 Zenith came up with the first automatic movement called El Primero. Till today the El Primero is one of the most iconic movements in the watch-world.
