Tap 12 to bring up the alarm on watch. This can be changed by simply changing the tap action. Tap nine to park hands. Tap six area to zoom. I only made the stopwatch second-hand area to become larger. This allows for better viewing if you are using the stopwatch function. Tap eight area to toggle screens. Tap center to start/stop the stopwatch. Tap three to reset the stopwatch. The stopwatch seems to be accurate with the tachymeter.
