Well, I now own my third pair of x-metals. Refer to the pic below. Bottom: Romeos that are in dire need of lenses and rubber. Have had these for 8 years, maybe more. Scored these from a coworker for 50 bucks at the time. The lenses beginning to crack helped that deal. Top: 2nd Gen plasma/ice Juliets. Inherited these from a close relative that had passed several years ago. These need a serious tune up also. Middle: Newest acquisition as of today. Juliets with polarized lenses that are really nice. These also came with the lense kit and case that you see as well as a set of rubber. The lens kit is the emerald. Now, having spent I think the last 3 hours googling, and then an hour + reading through the past 36 pages of this forum, it seems that this pair is the real deal, or at least I believe so based on what I have read concerning fakes and then seeing the info about the post 2004 no serial frames. Then found this thread which describes this pair exactly in regards to the "24-125 55 O 21" on the left ear piece: http://www.oakleyforum.com/oakley-x-metal-discussion/818-question-about-juliets-w-out-sku-frame.html If these are in fact real, then I did not do too bad considering I got all that for 140.00 Oh, in addition to having the t-6 torx screws and the rivets, I compared the weights of my other juliets and found that both pair weighed 41 grams, not that it means anything, but I'd doubt that the fakes would be that close in weight.
