Hi
@cassius66 and welcome to the forum! It's a little hard to tell based on your one picture of the dial, but I think the watch dial has been repainted (redialed). For a vintage watch collector, that's a reason to avoid this watch at any price. But a redialed watch might be OK for you if you're just looking for one cool piece that looks nice - lots of vintage watches have been repainted over the years by their original owners, as well as sellers who are trying to spruce up the looks of a tired watch.
As a general rule, vintage watch collectors prize originality over (just about) everything else. Some of us love the look of a well-aged watch while others hunt for original pieces that look like they just left the factory. If you're here to learn about vintage watches or you think collecting them might be a fun hobby, I'd recommend putting your cash back in your pocket, and spending some time reading the (free) threads on this forum. There is a lot of information on how to spot redialed watches as well as advice on how to find a crisp, unpolished case without potential problems with the mechanical movement inside. Here are a few threads to get you started:

Take some time to browse through other threads on this forum - there are many threads that analyze redialled watches from Omega and other brands. By this time you finish your eyes will be bleary but you'll have a good understanding of what to look for in a vintage watch. Don't be afraid to ask lots of questions. Have fun!
