Advice from the wise about this 16800 please.

[Doc Strange]

I'm interested in this sub. I love the matte dial with open markers.
But I'd like to make sure in not getting beaten up.
The band is marked 93150, which I think is appropriate.
The ends are 593, also appropriate, I think.
The serial is 803xxxx and the movement is a 3035.
The open 6 is, I believe, correct for the period.
As best as I can tell, the thick font on the insert is correct, too.
The date is not quick-set.
It winds nice and smooth.
It doesn't show in my photos but the bottom of the face around the 6 has tiny scrapes.
Any reason this watch is doubtable? I am able to get it for 5k with no information about its history. The case seems a little beat up but nothing frightening.
Experts? What am I missing here? Is there anything that doesn't seem original on this watch? Is the low price just a reflection of the beating the case has taken and the soft market for this model?
