Here's a Benrus Type II Class A diver with all the military cred you could possibly want.
Made for the U.S. Army in the early 1970s, the watch is a solid steel monocoque case, 44mm wide including the screw-down crown, by 48mm from lug to lug.
Black dial is excellent, and hands have a great golden patina. Crystal has some crazing, as photo shows, but nothing that detracts from the rugged appeal of this classic.
The 17-jewel automatic ETA movement keeps excellent time, with the hacking mechanism working fine.
