Thoughts on 1680 Red

[Peacefr0g]

I have just come across a, to my eyes, nice 1680 mkv at an auction house in Sweden. Thanks to the current eceonomical turmoil it seems that the watch might go for less than it would have a couple of months ago and if it doesn’t go much above ca 20k usd I might try to make it my first vintage Rolex.

No box and papers, supposedly unpolished and a good used condition. As far as I can tell the dial seems correct, lume is nice and even bracelet seems to be in ok condition. Insert almost too nice to be original but I can’t see anything obvious wrong with it either. Not sure about the “unpolished” part though?

Any thoughts? Many thanks in advance.
