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. Zenith Pilot Big Date Special comes with a 42mm stainless steel case, attached to the case is the brown calf strap with white stitching.
