I promised a friend I would pick the collective brain and get as much information on this watch that he inherited. It is in amazingly good condition as you can see from the photos. I assume that the serial number on the movement is the one that shows up on the Hampden serial # list, but I wonder what the relevance is of the number on the case. Anyway, I look forward to hearing back from you WISe folks and my friend is probably even more so. Thanks in advance.
