Zenith was purchased by LVMH in November 1999, becoming one of several brands in their watch and jewellery division.

It is one of the Swiss watch manufacturers that still produce their own movements in-house. The El Primero calibre, which was first released in 1969, and still produced today, was one of the first automatic chronograph movements.
