Case back is dated N1 and watch is engraved for a graduation from law school in 1972. It's in what I believe to be the original box. Caseback is a snap on, I think; haven't attempted to open it. Face is 2 tone green with white on gold markers and hands. Gold EP case and RGP back. Band is gold filled. "Bulova signed crown.
"Bulova" under "12" is printed in gold. I am assuming it's a 17J due to the fact it's a hand wind and face is unmarked for jewel count. Doesn't appear to have been worn very much. President variant?
