He may have meant by human hands. That was obviously done by the same reluming, redialing, out or focus picture taking monkeys we have seen elsewhere on the web.
I'm relieved to see the seller was honest enough to disclose the slight fading on the dial. Wouldn't want to lead a prospective buyer astray, would we?
"I'm afraid that I'm a complete Nerd when it comes to loading more than one picture so if you'd like more please PM me and I'll mail them to you direct." It would have been more to the point for the seller to have disclosed that, when it comes to hoodwinking buyers, he is a complete nerd as a swindler. Though Efauser has a point too in his post No. 7.
