Hey all I have the 38mm SS with Black Classic Buckle, and I also got a 42mm Sport w/Blue to check out the size. Since I've been lazy, I haven't returned the sport model yet. I was thinking I could probably use it as my dedicated workout watch, BUT then I found out you can only have one watch paired. Pairing takes a while, so it's not realistic to keep unpairing and pairing. So, that leaves me with my 38mm SS watch with the leather buckle. I kind of want to use it for when I play tennis, workout, etc. But probably getting it sweaty with the leather band is bad for it? I could pick up a sport band for it, right? Then I'm afraid of the constant swapping of the bands. Damn.
