the more I see the more this is a strange piece.. 925 was in Germany pre war and after....
The front piece I agree, separate, more than likely pressed and soldered on..
Maybe,,maybe the band is a weird multi piece.. I do own a bunch of these engravers/jewelers guild booklets,,,some strange stuff was done.. IF the front thicker part is hollow and even though faulted,,it could be a 3rd reich piece.... Well worth holding on to..
Benten my old friend,,when you get tired of it send it here buddy!
