I've implemented button press responses in various Apps without any issues, but when I use the same techniques in a WatchFace they don't respond. Is it possible to get a WatchFace to respond to button presses? My goal is simple, with a button press I'd like to make the seconds hand visible all the time or not at all through a variable passed into the onPartialUpdate method. In the not visible mode I'd only redraw the hands once per minute instead of every second, so it should be more power efficient.
