Breguet Type XX Aéronavale flyback chronograph

Breguet’s Type XXI and XXII collections feature 42 mm and 44 mm diameter cases, respectively. However, there is also a third, lesser known size, represented by the Type XX designation. The Type XX Aéronavale flyback chronograph is 39 mm in diameter by 14.4 mm tall, with fluted case flanks, polished lugs and a rotating satin brushed steel bezel. It’s the smallest men’s watch in the collection, and proportionally our favorite.

With a black dial as the background, the steel hands and Arabic numerals are treated with a white luminescent material that contrasts perfectly and offer excellent readability. The 30-minute chronograph hand at three o’clock is also luminescent. Visible within the 12-hour totalizer at six o’clock is a date aperture (also available without a date). The outer chapter ring has white graduations, with a dot marking every fifth minute. A polished flange completes the dial.


Unique to a flyback, the pushpiece at two o’clock operates the start and reset functions of the chronograph, whereas the four o’clock pusher controls the stop function. The idea is that you can start and instantaneously “flyback” and start again, all with one pusher.

Running at a frequency of 4Hz powers, a 25 jewel in-house automatic caliber drives the watch. Power reserve is 48-hours. Screw locked crown. Solid steel caseback. Water-resistant to 100 meters. Presented on a light brown alligator leather strap.
