Hi Rob, I noticed that one too. Regardless of how rare it can be it's indeed in quite a rough shape.
However that's the price the seller's asking - I wouldn't be surprised if he were ready to settle for much less.
Still, between bracelets, boxes and other paraphernalia, it is true the trend is really astonishing and much outpaces the already remarkable appreciation of the watches themselves.
Cheers,
Fabrizio
