i don't have large wrists so was worried about how large the 42mm looked in many pictures. I ordered the 42mm SS with Mil loop. I tried on the above, as well as the SG Sport, both 42mm, just so I could get a feel for both bands. I'm delighted with my choice, no regrets at all! I did try a 38mm on as well which just looked tiny on my wrists. Both the SS & SG sport look awesome. I didn't really pay attention to the silver Sport so can't comment. I think it's really important to visit an Apple Store and try out the watch for yourself. Had a fantastic experience at my local store in Edinburgh. Loved the taptics too, without a doubt feels different from a normal vibration.
