I just got this issued, worn, untouched Glycine Airman with its original wooden box.
The movement is an A. Schild AS1701 modified for 24h and enhanced by the ingenius zero-stop mechanism: the seconds hand stops at 0 if the crown is pulled.
The pointed extended tail of the hour hand is used together with the revolving bezel for a second time zone.
Enjoy,
Mick
