I owned a Space Gray Sport for about a week before I decided to trade up to the SS model. I found one at a store a couple of hours away and put it on hold since I was traveling that way this past Saturday. I don't think I'd ever even seen the SS model in person, but man do I really like it. One of the big reasons I wanted to trade was the sapphire crystal. I can be tough on a watch, and I figured sapphire was a good investment. It was one of the things I liked best about the watch I've used for about the past 15 years. To me, the SS model just has a great look. The black screen and crown insert are really offset by the shiny metal. When I'm driving with my left hand on the wheel, and the sun hits the edge of the watch, the starburst is impressive. I was a little concerned about the weight of the SS model, but I never even thought about it when I put it on. I had worn it for about an hour before I remembered that I was afraid it might be too heavy. I have the Milanese Loop, so it doesn't add much weight. I just wanted to share my enthusiasm. I think I made the absolute right choice. I'd love to get a tan leather band. The pictures I've seen of that combo look very sharp to me.
