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. Inspired by the early days of aviation, the Pilot Montre d'Aeronef Type 20 Annual Calendar really ties in vintage looks of the time with a modern approach. The brown alligator strap is fastened onto the stainless steel case. The arabic numerals offer great visibility against the black dial in both day and night conditions with a coating of SuperLuminova. The El Primero movement powers the watch and features the annual calendar complication.
