Fernand Péchoin chronograph fly back Pilot Type 22

A very rare French ‘Type22’ pilot’s watch
The movement and the case of this Fernand Pechoin are really in good condition. Pechoin was the
case manufacturer for, among others, Breguet.
Fernand Pechoin pilot watch from the French manufacturer.
Developed for French military pilots at the time, and although it was certified by
the Besançon Observatory (observatory hallmark on the back) it failed during development.
