I literally JUST discovered this from a review video, it's not even mentioned in the tonnes of "how to" videos tag made about the connected watches: If you choose the 3 counter chronograph watch face...tapping the watch starts teh actual chronograph (as in the regular watches, the big second hand is the chronograph's second, not the watches second hand), resetting is double tap. OFC the 2 totalizers work as intended.

This just blew my mind!
