http://www.ebay.com/itm/RARE-OAKLEY...337360601?pt=Wristwatches&hash=item4d253ee4d9 I saw this Blue MM on the bay and noticed that the clasp is different from mine. Mine came from a trusted member on this forum, boxed with a serial on the box and a couple of other traits that make me confident that mine is a real one. This one on ebay has a clasp with etching and mine does not. Mine is smooth. I wouldn't think that on a watch with the supposed production of 150 that there would not be differences in construction. What do you think?
