great question, as this one is going around in my head. I'm wanting the watch for the sport/fitness/fun aspect more so the dressy impressive higher end watch, but still want to use it for business casual dress. I love the silver with almost any sport band color and will as such purchase black, blue, and green. I love the look of the aluminum space gray and think all the bands look good as well, I'm just concerned about brown shoe and belt day, having the correct band to mesh with them. That's where I see the space gray as different, in that it looses the sport and fun factor because it is more wardrobe specific. But what do I know, I'm wearing brown shoes and belt with a dark gray/black kenneth cole watch, so who knows. I'm going for the silver because it seems to have a more fun/casual look.
