I plan to have it always on. If it can last 2 to 3 days like it claims, I dont mind having it always on and only lasting a day and charging it daily. The watch looks so silly if someone looks and it and its off.
Currently using always on because sometimes I just like taking a "peek" at the watch, particularly if I don't want to be somewhat discreet. Part of the problem for me with waking up a watch to look at it, is that it can be perceived as rude when you are with company. "Why do you keep looking at your watch? Am I boring you?"
