In tribute to the famous Breitling Datora watches, which were bestsellers in the 1940s, this chronograph with complete calendar is distinguished by its unique way of showing the date. Embodying an authentic demonstration of mechanical ingenuity, its selfwinding movement displays the day and month in two side-by-side apertures, while a half-moon center pointer indicates the date around the dial. In addition to the aviation slide rule and the tachometer, the dial also provides a second hour display in 24-hour mode, also known as “military time”..
