Welcome
The case design of the 5110 doesn’t have a lot of sharp lines (not like a 5970/5070) so it’s harder to spot overpolishing.. also the case is in platinum, which is harder to overpolish..
Given these 2 factors I won’t worry too much about it
But I would really ask for more pictures than what he has sent you (eg pics of all the 4 lugs, bezel etc) if you can’t make the trip to inspect the watch yourself
Remember.. what maybe important is what he is not showing you, that where you need more pics..
