Although smaller than expected, it surprisingly fits my small wrist. I got this both from having to stop getting my phone out for a while and to prepare for BMT. I still have to test whether it is really waterproof. As long as it holds up for showers and pool activities, I'm happy. (I'll update this review once I've tested it a few times.) Comfort 10/10. I put it on and it's so light I barely feel it even though it's buttoned tight. The buttons are relatively small, but I didn't have to sacrifice a nail or hurt my fingers when I pressed them. I put her on military time. because that is my preference. It's very easy to change this if you prefer a regular time. All in all, this is a great watch and I can only recommend it.
