Am I the only one who doesn't wear a watch (even if I wanted to) because I don't like the way it scratches against my MacBook Pro?
I find it hilarious that you name the exact model of laptop.
I think it's reasonably to say, "Macbook Pro" as a generic reference. Nothing is really gained/lost by saying, "Mac Laptop". And, you do need to distinguish it's your unibody mac laptop, not a dell laptop, which likely doesn't mind being scratched by a watch that much. This is a Point for Dell! - My Latitude 2120 has been all over the planet in all sorts of rough conditions, doesn't have a visible scratch, unlike my macbook air - which is pretty ugly (but still working) shape after the same two years.
