Why would Garmin make a watch with such small small small screwdriver needed. And why does Garmin have contradictory information about which battery to use for the VIVO fit several times on several websites etc. it says CR 1632. I bought twoI bought paid $20 for a tool that had about 12 different sizes. It had the one suggested, but it still cannot get the battery out. I then went to a local hardware store and paid $10 for another screwdriver set that had the exact same size but had a pointed edge and was able to get the battery screws out overall I spent close to $40
