I caught a space gray and black sports band in the wild, and I was disappointed. It looked cheap. The screen was smudged from fingerprints and the band seemed on par with my Fit Bit HR. Now, I take care of my electronics (I've never dropped a phone, and my 6 year old notebook looks immaculate to the point that the Apple Genius I showed it to a few months back didn't think it was so old) so I don't think my Watch would look the same, but I was taken back. Honestly, and I say this without seeing any other Watch in real life, outside the sterile setting of an Apple store or other, that I am skeptical of the aluminum model now as any sort of fashion accessory.
Like I've said in previous posts, either I go cheap and get the 42 aluminum/b.rubber watch (Version 2, whatever that Watch may be because I am not going to by a version 1 of this) or I go big and get the Milenese loop and stainless silver Watch version. But, man, was I disappointed in seeing the space gray and black rubber version in the wild.
