Hi! I have the Garmin 645 that I have been using for many years. We just got a new Garmin 145 from a friend and I set it up for my son to use. Well, after playing around, I am beginning to think I want to use the 145 and give him my older watch. He is pretty young still and lucky to have a watch at all. lol. The screen is just so much nicer and clearer. Is there anything I need to know about flipping the watches over on our accounts? I don't want to lose any of my activity info. Also, are there any features I might miss? From what I can see it does almost everything my Garmin 645 does. We are both only runners.
