Scotch Brite polishing method on ss submariner bracelet

[Seddyspaghetti]

Hello,

So unfortunately i banged my bracelet buckle while closing a door which thus gave it a somewhat noticeable scratch. I'm interested in the DIY scotch brite method as I dont want the whole bracelet polished. I just want that scratch gone. Now my question is, can i just run the scotch brite pad on that right side where the scratch is? Or do i need to do the whole buckle so it will look uniform?

Please see pic. Thanks.
