I know this is crazy, and I really don't know how it happened, but for some reason I setup my wife's Apple Watch on my iphone and mine on hers. So we basically have each others watches. No biggie if it wasn't for the fact that I wanted the 42mm and she the 38mm - again, can't figure out how that happened. Crazy - my bad. (I told her to get a different color! Ha!) My question is whether there's an easy way to make the swap of data short of setting back to factory settings and starting all over? Any suggestions on how to do it?
