Welcome.
The price is fair. Nice watch. It looks good and notwithstanding the bit of polishing, lugs still retain some sharpness. (Caveat: I’m still learning, too.) I bought a very similar watch a few months ago (here on OF - and for just slightly more $, too!
). The 286 is a robust movement - my watchmaker’s personal Omega favourite. Interestingly, my caseback lists 135.002-62; this and the 20xxxx SN indicates a 1963 model. This one indicates 21xxxx yet with a 135-007-66. Not a deal breaker, of course, but I await someone with deeper knowledge weighing in here.
