Swiss Zenith 50th El Primero Anniversary El Primero A384 Revival 03.A384.400/21.C815

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 El primero - which still to this day is the most precise series-made.
