This is a quick very long video about two “smart” watches, one which isn’t all that smart and another which is more of a phone than a smartwatch.
In case you want one for some reason, here’s where I got ‘em:
Bluetooth U80 Smart Watch (AliExpress)
KEN XIN DA W1 Smart Watch Phone (AliExpress)
Don’t take those links as an endorsement, though I do kinda enjoy the Ken Xin Da watch for music and emergencies on the go.
