Authenticity Check

Hey everyone, recently just purchased my first Omega. Did a bit of my own research and decided to pull the trigger on a watch that I liked as the ebay listing was gaining traction, but I would appreciate any feedback from the more experienced collectors on this purchase.

I've attached the original listing as well as a link including photos and video of the movement (phone video makes hour markers on the watch look odd, pictures do more justice).

Thanks for the input

Thank you for the welcome! I will definitely look into the crown too.

I believe those two references have different crowns. You can see what the original looks like here: https://www.omegawatches.com/en-us/watch-omega-seamaster-omega-st-166-0037
So from my novice perspective, your crown has the right number of teeth. I'm actually not sure what's wrong with your crown except for that the color seems a bit off, and that the feet of the Ω are wrong.

The right one might be here, but I'm not 100% sure: http://cgi.julesborel.com/cgi-bin/matcgi2?ref=OME_CS^166.0037

edit: actually that link may not be that helpful, but there is this one on ebay at the moment that MIGHT be correct. You might wait for someone more experienced than myself to verify, though: https://www.ebay.com/itm/334500256950?hash=item4de1c4dcb6:g:3FIAAOSwCRdhfAV4
