The Montbrillant Datora pays homage to the classic Breitling Datora watches that were popular in the 1940s. This impressive chronograph features a complete calendar and a unique way of displaying the date. Its self-winding movement showcases the day and month in two side-by-side openings, while a half-moon pointer on the dial indicates the date. Along with the aviation slide rule, tachometer, and 1/100th of an hour display, this watch also has a second time zone in military time. Available in the sleek REF. R2133012.G624.737P.R20BA.1 version.
