I hope you find out what the problem is, the only thing I can think of is when I looked into the watlla watch they seemed to mention the Bluetooth loosing signal easily and they suggested moving the watch on the same arm as the miao miao but I suspect you have already read that, my ticwatch is still working o.k. at the moment although I did have a nasty fall last week scratched the metal outer ring but the watch seems okay, unlike me I have broken ribs again a sign of getting old I suppose
