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 Chronomaster 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 cast from stainless steel and features a diameter of 38mm, a leather strap secures the watch to the wrist.
