Maybe that will work? I already tried replacing the watch battery.
I think your G3 is out of calibration. I had this on a couple occasions with my previous Powertap hubs (but not with a G3). Powertap will recalibrate it for a fee. You need to call or email their service people for a return number and ship the whole wheel to them.
