Moved from a S0 38mm SS silver watch to the SS gray SB S2. Quick impressions: - I don't notice a marked improvement in responsiveness (so far), but there is some. - I really liked the silver frame on the S0. I always thought the contrast looked nice. However, the gray is "elegant." So much so that it seems to "out-class" the black sports band a little too much IMHO. Still getting used to the darker watch. I will try my silver Milanese this evening to see how it looks. - The gray watch shows smudges much more than the silver frame. Not a big deal at all; simply something I noticed. - The new black sports band seems softer, while the S0 sport band seems more rubbery. I prefer the S2 sport band. - The S2 is indeed easier to read outdoors. This was a main driver for me, and it works.
