The Avion men's chronograph watch from CITIZEN is a vintage-inspired timepiece reminiscent of transatlantic flights from the 1950's. Design cues taken from the golden age of travel include the rich black leather strap with contrast stitching, luminous markers and a classic date function. The 44mm black ion-plated stainless steel case houses the grey dial with 1/5th-second chronograph and 12/24-hour time subdials. Featuring our Eco-Drive technology - powered by light, any light, this watch never needs a battery.
