A most recent official PLA Navy diver, 21j, day-date automatic“Miyota”movement, mineral crystal, one way rotated bezel with solid stainless steel oyster strap. It is a very Rolex Submariner look alike watch.
This a very special presentation watch to the particular person (Awarded? General?) in the navy. The original owner's name is printed on the dial above the 6 hour marker. I have also found another version with navy unit number and some commercial version with nothing imprint on dial instead.
