In creating this chronograph with a traveler��s soul, Breitling decided to think big. Great comfort with the ingenious Manufacture Breitling Caliber B04, visible through the transparent caseback and equipped with revolutionary entirely crown-adjustable dual timezone system. A large size with an imposing 48 mm-diameter steel case and a perfectly legible ��instrument panel��. Equipped with the famous aviation slide rule, the Navitimer GMT is also available in a red gold limited series. New horizons for a legendary model.
