Sure its fake,even when you dont see the datewindow,biggest tell is the way the hands are attached,in german Zeigeraufnahme,couldnt find any proper translation! Gesendet von meinem iPad mit Tapatalk HD
Open the caseback.there where the stem goes into the movment is a little screw to fasten the stem.
Unscrew it then you can put in the stem again,check if you can move the hands,than tighten the screw again.
That should do the trick.
