So the 42mm is better for usage? I have small wrists is the 42mm still good to get?
I'd love if someone would comment on it, but that's what I've heard, like that the mm size doesn't really correspond the sizes that normal watches use, and that the larger one is only slightly larger, but easier to use, and the review I was reading was recommending it for everyone... but maybe not everyone agrees?
The 42 is definitely easier to read and interact with. However, I have VERY small wrists, so the 42 is to big for me. It's not a matter of looking too big, it's a matter of the watch being wider than the flattest part of my wrists. So look at the wrist size guide Apple has somewhere, and if your wrists are toward the smallest available sizes, get the 38. Otherwise, I'd go with the 42. But it's also personal preference. Some people simply feel that the smaller size looks better / are more their style.
