The Vintage Breguet Type XX was commissioned by a famous French military in the 1950s used by the French Air Force, Flight Testing Center and Naval Air Alarm.
The Type 20 had a number of features that apparently were military specifications. The case was relatively large for a military watch at 38mm, with black dial, luminous Arabic numerals and hands, a sweep second center column chronograph hand, and 2 subdials at 3 and 9 o'clock. The subdial at 9 was a small seconds indicator. The chronograph elapsed time subdial at 3 had special markings for 3, 6 and 9 minutes. The bezel rotated, in order to keep track of elapsed time.
