Nope!
It is a french quality mark from the CETEHOR (centre technique de l'industrie horlogère) in Besançon, it has nothing to do with it being officially issued or not. 1, 2 or 3 stars depending on the complexity/quality. Usually issued watches for the french airforce have warranty service marks stamped on the outside of the back (FG + some number). I suppose more than a few of those were privately bought and flown in service by military pilots though.
EDIT : for reference
