Looks totally legit to me. We can't really judge condition based on those photos but the dial does seem to have some issues and the case seems well-polished, which will affect value, as will the size of the case (i.e. 34mm). Value is also a bit tricky to estimate, because it depends on context, who you are buying from, etc. That said, very roughly, I'd put the value in the $400 range.
