Real, Fake or Frankenwatch?

Hi Omega Friends! I recently bought this Vintage Seamaster 120 166.027 from an eBay seller with 1500+ positive reviews. But... there are a few things about it that I’m concerned about. 1.) the 565 caliber movement should be a 24 jewel movement I’m guessing it was replaced with a caliber 563 17 jewel piece? I don’t mind this. 2.) The bezel looks less matte than other references I’ve seen, is that just the scratches/patina? Or is it fake? 3.) My heart sunk when I saw the last one, the omega Symbol looks more curvilinear that what I’ve seen from other references...has anyone seen one like this?

Did I make a big mistake or is the watch I bought salvageable? Thanks so much!

Oooof brutal... Yes see below.

Damn! Thanks so much for the help..do you have a rough idea on the stand alone value of a 563 movement?

I've bought a few "donor" movements off eBay and 565's usually go in the $100-200 range depending on condition. 563's sell on the lower end of this same spectrum---probably around $125-150 for the one you have.
