I have settled for this as my primary. Will probably replace AQI with Messages when the update is available. I also have this one to the right for accurate digital time and timers. Useful for setting clocks if nothing else (I got Donald Ducks license plate remaining on the timer. Happy coincidence) I also have a modular infograph that I'm not really using but the idea is to use it when I want to keep an eye at my heart rate. One for keeping track of international events like Apple keynotes and similar that are taking place in different time zones. And a discrete one that I use in combination with theater mode when I want to check my time without my watch lighting up the room.
