So I am about to see Age of Ultron tonight and I am considering not taking my Watch with me. I have noticed that sometimes the screen lights up if I move my arms and the screen is pretty bright in dark rooms. I would hate to be that guy that annoys those around me with the small, albeit BRIGHT screen in the middle of their movie. Has anyone tried this yet and would like to detail your experience? I am also considering just putting the watch in either Airplane mode but will still get the watch face with a big arm movement, or Power Reserve.
