I have to re-register every time I come back to this site, despite using the correct log in details!!! I posted the comment by gb10. Watch worked perfectly for 5 months when it stop tracking HR and switching on display with the gesture, while playing golf. Not the first time I played with it on.

FIX it yourself and get on with your life!
