Aviator Watch Airacobra Chrono Auto Mens V.4.26.5.175.4. The Aviator Watches Airacobra Auto is a homage to one of the famous WWII American military aircrafts. It was in the 1940s that pilots began receiving watches as essential equipment for missions, and this model is a subtle evolution of the typical pilot watches of that time. While the classical case and the instrumental look of the dial keep a military aviation spirit, the applied numerals and sophisticated chapter ring give a taste of modernity and elegance to this model. Three baton markings at 3, 6 and 9 o clock provide an emphatic cockpit instrument style.
