In honor of the 1940s Breitling Datora, this complete calendar chronograph is defined by its unique date display method. Its self-winding movement presents the day and month in side-by-side windows, while a central half-moon hand indicates the date. The watch also incorporates an aviation slide rule, a tachometer, and a 24-hour military time function. REF. A2133012.Q509.222A
