I had a problem where if it would charge, it would rapidly switch from watch face to clock motion charge status... it would sit at a charge number then switch back to watch face, then switch back to beginning charge again... and cycle until it was dead...
I ended up replacing the battery, but that alone did't fix the issue. It did start up w/ a charge initially but never fully charged and ended up being a brick again regardless of what button i pressed or did.
I then decided to use a multi port USB charger... I chose the 2200 am charger ports instead of the 800 or so that came w/ the unit... n battery went to charge mode and now fully functional. I may just leave my watch in the kitchen where the charger is instead of up in the bathroom... at least I got a smartwatch back for less than $30... thanks for everyone's posts in troubleshooting.
