The company was started in 1865 by Georges Favre-Jacot at the age of 22, in Le Locle in the canton of Neuchâtel. Zenith was purchased by LVMH in November 1999, becoming one of several brands in their watch and jewelry division. Zenith has a long reputation for the quality and precision of their watches. It is one of the Swiss watch manufacturers that still produce their own movements in-house.
The El Primero caliber, which was first released in 1969, though still produced today, was one of the first automatic chronograph movements.
