Had been losing time recently. Tried the re-calibrate twice round the dial trick but that didn't do anything . At 14:40 yesterday it died. Had c 100% battery as charged a few days before. Button works fine i.e. not broken. Charger I believe is also fine. Watch unmarked. Placing on charger doesn't do anything. Leaving it to discharge may take many years. Carefully washed in warm soapy water (I think that is so its clean when it goes back).
Really disappointing as loved the watch and its battery life. This seems to be a very common problem with this model - will a replacement be any better. Even if one of these hacks or tricks Withings describe worked would I really want such a flaky watch?
