The designation Suverän in that leaflet refers to the movement in the watch. The movement in the Suverän model is basically the same as in your watch.
This leaflet is the Last one that design this watch like Suverän (1950)...the movement was winning a price but.... i was thinking that Suverän was only the watches provide from switzerland to help sweden...and i was thinking they are all with screw back. Thank you
