I just wanted to let you know I am wearing a 38" watch band on my 42"mm watch. I like the look of the smaller band on my 42" watch and fits my wrist so much better!! Here are some photos of what it looks like.
These photos underline why I chose a 38mm. That thing looks crazily huge on your small wrist. I have small wrists, too, and the 42mm looks insane. (I tried both on.)
