Haven't tried the Round, but the battery life is hard to deal with... Honestly, I think if you get a black Time (or one of the Time Steels), you can make it work even in relatively formal situations. Because the main unit is relatively thin, you can even get it under your shirt color easily. I have a red Time, and even then people just assume it's a sports watch or something before they see it light up with a message on it.
