Breguet started producing the 'Type XX' around 1954 becoming the company's most sought after post-war aviator's wristwatch. The reference has a special flyback feature, so-called by the French Air Forces 'retour en vol', which enabled pilots to quickly reset and instantaneously restart the chronograph by means of one pusher.

There are three generations of the 'Type XX', the first of which was introduced in the 1950s and of which the present lot is an example; the second known as the 'civilian version' introduced in the 1970s; the third version is currently available on the contemporary market and is known as 'Type XX Aeronaval.'

A special feature of this particular watch is that it is the version with a 15-minute chronograph subsidiary dial, instead of the usual 30-minute counter found on the more common Air Force models.
