Rolex Tudor 7928 pointed crown guard chapter ring.
The Rolex Tudor Submariner has a lot of military history know as the stepbrother of the Rolex Submariner 5512 & 5513. There was a wide enough cost difference that it could more easily meet the tool watch requirements for military men.
It is not as wasy to date tye Tudor but this has a 39x,xxx serial close to where the civilian big brother aka Big crown 7924.
They got a lot of anuuse the old Tudor subs so finding them in good condition is always a pleasure.
