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 calibre. The large blue central seconds hand help's users read the 24-hour second timezone indicator on the flange. The watch is powered by the Elite Calibre 682, giving a 50-hour power reserve.
