Question is: If you want a
good 168.005, then why go for this one?
Or do you want a cheap 168.005? That’s a very different thing.
I believe that most of the dial will look nicer under a fresh plexi - some of the dark dots are not on the dial itself. However, the discoloration around 6-8 or so on the edge of the dial looks like moisture damage. I’d say it’s unlikely it can be removed or at least a massive risk.
Then there’s the case, which is heavily polished. Yes, you can still guess where the edges are. Compare to this lug though, that’s about what an unpolished (or close) one looked like:
Minor other issues are the incorrect crown, for example. You’ll need a service, movement looks a bit dirty. And it won’t stay at 1k. So in the end you’ll usually end up with an example that’s more expensive than you thought, but that’ll always stay mediocre at best.
The usual dogleg advise: They aren’t rare. Buy the best one you can.
The usual vintage watches advise in general: Condition, condition, condition.
You probably won’t look back at having paid a little too much. But mediocre condition will remind you every single time you glance at your wrist that you didn’t wait till the right one came along or till you had saved up to afford a good one.
