Hello,
i’m looking for replacement of start/stop button micro switch. Do you know what is the switch number which i can look for?
Thank you
that's my problem too and i can't find any solution.
Where can I find a replacement Motherboard ? None of my buttons are responding and I can’t even do a Factory reset.
All that works is switching off and back on.
I have exact same issue. I sent my watch to official repair service to Split (Croatia) and they said they aren’t able to fix it. I can see only main screen of the watch, buttons don’t respond at all. Would like to know how to fix the issue.
