I went, I saw, and I tried them on. I see many people say the 42mm is not too big. That was my first impression. However, after I repeated tried the 42mm and 38mm, I determined that my first impression is wrong. The 42mm, at least to me, is too big. Why? That is because when they let you put the watch on, the band is usually a little loose, and the watch would fall over to the widest part of your wrist which is the wrist joint so the watch does not look too big. If that is how you usually wear your watch, a little loose, fine. But if you are like me who likes to wear his watch snug, the face of the watch would fall right on the narrowest part of the wrist, and the 42mm might look overwhelming. After I asked the Apple guy to adjust the band of the watch for a snug fit, I found that the 42mm is indeed too big. Even though it looked good at first when it was draping down my wrist. So make sure you have the band adjusted and wear your watch at the usual position on your wrist before you decide whether the 42mm is too big.
