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 petite 33mm case conceals an Elite 692 movement that provides a 50-hour power reserve. The addition of a moonphase and shiny grey strap make this watch instantly recognisable.
