Here is a WW2 Kriegsmarine U-Boat clock out of my collection. If anyone ever watched the movie dos boot there getting depth charged and you see the U-Boat clock crystal crack from the explosion of the depth charges. This clock makes me think of that movie. The N on the dial for the North Sea Fleet. Still has most of the original black paint someone did polish the bezel ring. Most you see all the black paint gone.

Great piece!   Rich A. in Pa.
