Notes

The title "retour en vol" refers to the instantaneous fly-back feature of the chronograph work. A single push on the lower chronograph button zeroes the chronograph hand whilst still in motion, which then restarts immediatly, avoiding the need for a pilot to break concentration from the control of the plane.
Provenance: Mr. Pierre Dufresne, pilot at a Flight test centre.
