It seems that I have a scratch or a dent near the date window.
I can't really say what it is, I just noticed it a few hours ago when it was fine yesterday. I thought it was a stain because as far as I know I haven't been knocking the watch on anything hard that could cause that deep of a dent, because I'd definitely remember if I did.
I've been trying to rub it off with water / a bit of soap but it still won't come off.
I've bumped my watch few times previously but still no scratch. So it's very weird. I can feel a bit of a dent when scratching it with my nails.
Any ideas on what it actually is?
Does polishing with diamond paste work? or is my only option to send in for a replacement crystal (if they have it?)
