A little over a year ago I purchased a Stowa Flieger Baumuster B and today is about the tenth time I wore this watch.
As I was about to put it on I noticed looking through the back that the rotor hardly moves, unlike my Schauer Kulisse #10 which with little effort the rotor spins a few times.
Is this normal for this model of Stowa?
Also could you please tell me about and show me some pictures of your Stowa Prodiver?
I am about to purchase a new one.
