As I have two of them I think I am going to sell this nice fully working and very sought-after Kriegsmarine "KM Alpina" dial marked navigation watch (Beobachtungsuhr) of third class (3. Klasse) made by Alpina, Deutsche Uhrmacher-Genossenschaft (Cal. 355) soon. The number of the movement is 94355. The number on the back of the case is 313491. Opinions are welcome. Regards, Florian
