CITIZEN's Avion 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 leather strap with contrast stitching, luminous markers and classic date function. In a rose gold-tone stainless steel case with indigo dial this timepiece now has the added 1/5th-second chronograph and 12/24-hour time features. Featuring our Eco-Drive technology – powered by light, any light. Never needs a battery. Caliber #B620.
