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. Featuring the Elite Calibre 681 movement and just 7.6mm thick, this Heritage Ultra Thin is the perfect choice for work or pleasure.
