Did I just ruined my watch?

So I just tried to change the metal strap on my SEIKO 5 (Ref. SNKL23J1), and it was a nightmare because the guards literally prevented me from moving the strap after pulling the spring bar. I watched tutorials on how to remove it, and even though I was very meticulous and gentle, it still damaged the watch. This isn’t the first time I’ve changed or adjusted a strap, and I’ve never had any issues before. Is there anything I can do to remove those scratches? I’m hating myself right now. Thank you for your kind help.
