How many scratches is too many scratches?

I just purchased this series 6, Apple Watch 44 mm with gps and celular for 80$. It’s got a few scratches and honestly, I didn’t see all of them until I reflected it on the light I just purchased ice cream protector that should be here in a few days but how many scratches are too many scratches for you guys? It’s my first ever Apple Watch and I am wondering if I am actually going to enjoy it so I can upgrade it maybe in a year or two.
