I reset the watch after fiddling with it a bit. When I turn it on it gives the option for choosing the language. Once I choose English I get a low battery message and am told to connect to the charger. I've done that, but nothing else happened. It arrived at 53%. I can't imagine that I've used it up to the point that it can't operate while on the charger. I'm going to wait awhile and see what happens, but I hope I haven't screwed it up.
