Founded in 1865 by Georges Favre-Jacot, Zenith has a rich history in the manufacture of Swiss timepieces by producing watches which have become icons. The most notable achievement was the creation of the first integrated automatic chronograph movement - the Zenith Chronomaster - which still to this day is the most precise series-made calibre. The 36'000 VPH features the legendary El Primero movement which has earned legendary status. This model features the El Primero 400 B movement which gives 36,000 Vibrations per Hour, thus giving the watch its name. The case is from scratch-resistant ceramic and features a diameter of 42mm, a black rubber strap secures the watch to the wrist.
