Just got this it's a Benrus type II class A diver issued to the US military in the 1970's.Has a 17 jewel movement,hacks,rated at 1200 feet.I like the dome crystal on this diver.It was service by Jack at IWW so I knew it was in good shape when I bought it.The lume is still good on it.And it came with three straps I like the one with the deployment buckle on it.
