Soo at the beginning of October I bought a 745 and used it daily even today. The problem is that on two occasion the hold function on the UP and DOWN buttons stopped working and it just started scrolling through my widgets. When that happened I just restarted my watch and it went back to normal both times but a day or so later it restarted again automatically. What does this mean should I go back to the store and get a refund or ask for a new device or is this somehow normal (which I hope it isn't) ?
