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. A calibre El Primero movement powers the watch and features a date complication. Other features include a 50 hour power reserve, sapphire crystal glass and a brown leather strap.
