1954 Auricoste Chronographe Type XX flyback

In the 1950s and 1960s, “Type XX” chronographs were created for pilots in the naval air force and the flight test center.

These distinctive watches had to respect a set of specifications drawn up by the Ministry of Defence. They must have a flyback function, a 38mm diameter case, a black dial with luminescent indexes and hands, a mechanical manual movement with a power reserve of more than 35 hours, and a relative precision of + or – 8 seconds per day.

The plus of the Auricoste Type 20, a bidirectional notched bezel with a single marker and the Lemania 2040 movement.
