The Type XXI watch was inspired by the Type XX chronograph designed by Breguet for the Aéronavale française (the French naval air arm) during the 1950s. Its technical distinctiveness lies in a chronograph minutes counter positioned in the centre, like the seconds counter. The self-winding mechanical calibre also has a flyback function, which is specific to aeronautics and allows the chronograph counter to be reset to zero and restarted instantly with a single operation.
Introduced in 2011, the new Type XXI has for the first time acquired a grade 2 titanium case with a black lacquered rotating bezel sporting numerals in relief. Its aesthetic was inspired by that of the former Type XX models from the second generation, developed between 1970 and 1984. Its functions include a date, a 24-hour indicator and a small seconds hand. Its case, 42 mm in diameter, is watertight to 100 metres thanks to a screw-locked crown.

The flyback function: pressing the lower button returns the chronograph to zero and restarts it immediately. Without this function, three separate operations would be necessary to achieve the same result.
