I'll have a go at it. I'm far from a vintage Seiko expert but I am fairly good at Google. I think what your friend bought was this exact watch at the link HERE from antiquesf on ebay. I can find other images of the watch on other sites but they all lead back to two recent ebay listings. It was listed for $620 initially but it didn't sell so it was relisted as an auction that just ended recently. It will be tough to see on your phone but if I blow up the images on my computer, I can see a few distinctive marks on the case and bezel that match exactly. At first I thought maybe it was just a 6119 dial and movement that was re-cased but after looking at images of other 6119-8080 examples it appears to be the same exact original case. The lines are the same. However on many of these fivers the bezel will pop off just as they will on the divers or dive-style watches. You can see what I mean HERE on a newer 5. So I think someone popped a new rotating dive bezel onto this thing. If you look at other 8080 cases, they appear to match up.....which is why the caseback matches the dial.....those parts are all original. That's also why we see a tiny tucked-in push-pull crown on this "diver". Although I can't find a perfect profile image, I'll try to drop a pic below that shows what I mean about the case. There are more on google images but they can't be viewed properly from their sources because they are lost down the Photobucket forever.
Not the right profile but this seems to be the one in the best condition.....from a user named siralan on wrist sushi.
Anyway, moving on to the bezel and insert. Like I said, I think it's probably not original. Zooming in on the third photo from the ebay link makes me question whether the bezel and case are made for each other. I'll drop that photo below. Even though the watch overall is in good condition, that bezel insert is in outstanding condition and out of proportion with the wear on the case if you ask me. I don't have to tell you guys what normally happens to the printed/painted dive time markings. Also, if you look back at old Seiko divers and "dive-style" bezels, it's really rare to not have a lume pip. Even when old Seiko inserts have that triangle at zero, it often has the lume pip too. Also, I can't find a damn thing similar to that insert in a Seiko related google search, and I usually can. It makes me wonder if someone popped a non-Seiko bezel, or at least, insert on this thing. Also (and I think this is important), this is a really cool looking watch and I think it would be noticed and considered desirable. To only have one photo out there is a bit odd. I think if there were a few more examples out there they would show up in a search......if not of 6119-8080 searches, than of vintage Seiko 37mm dive-style watches.
Hopefully your friend enjoys it whether he finds out any more about it or not. I've rambled enough.
It does look like an 8083 case as well which would match the dial and caseback. I wonder if someone managed to mod a rotating bezel on it. I wouldn't mind finding a rotating bezel that somehow fits. I have a silver dial 8083 that's missing the bezel.
Over the last couple of days I have been finishing some TST parts off to complete a batch ready to send off to there owners and today I had this one pop up, I must admit I was at a loss for a couple of seconds trying to work out where the problem was :)

Guys with this new format we have to clean up this particular forum as this is where most of the traffic is going . To get to the actual current discussions we have to scroll past all the Review discussions that are stickied to the top of the page: "Seiko Review, Citizen Reviews,..... Parts...
What do you all think is the best vintage Seiko that can be bought for less than $200? Something inexpensive that can still hold the interest of a big budget Seiko collector, or that would make a great first watch for someone getting into vintage?
My vote goes for..... The M159. I love this...
