Hi there, welcome to the forum. It's great to see you doing your in-depth research. Whilst I am not familiar with this model, I appreciate the effort you've put in and I'll try my best to weigh in. Bear in mind I'm still a new collector but these are just some observations I noticed and it might be something you want to investigate/consider further.
1) Again, I'm not familiar with this model/case but the grain on the sides looks different from the grain around the watch face. It doesn't seem to extend all the way to the bevel to so the case might be refinished at the very least. That being said, bevels are still present. The case is in decent condition and I would gladly own this watch if I ever was interested.
2) lume at the end of the hour markers appear to be relumed. Too uniformed and omega tends to have it nearer to, if not touching, the hour markers.
However, it's important to note that none of these are a deal breaker to me. With regards to the pricing, I love the earlier movements more so I'm do not look into these later models. You can find seamasters with cal 35x and 5xx in that same price range and condition if you're patient enough.
