I had another military Tudor, it was a 7928 similar to yours. Probably made after your great looking watch.
I sold it thinking I was going to buy something more interesting, I had no idea how expensive these watches
had gotten. Big regret, but we live and learn.
This one came from near by Camp Pendleton (Marine Corp) area. There are lots of navy and marines in that
area. Plus I had no shread of supporting documentation for the watch so it was for all intents and purposes just a 7928.
