Reccomend a watch for my 9 year old son

[Nateismine]

I'm looking for a good watch for my son. Ideally I'd like the childs equivalent of a garmin running watch. Does such a thing exist? I want more than just a step counter - a minimum of alarm and multiactivity tracker. Looked at the Vivofit 2 but its a bit too young. Any suggestions? An adult garmin would be too big and a bit too expensive. Thanks

Mi band 4. My boys 9 and 11 really like it.

Perfect, thank you.

Yes my son is 12 and him and his friends (some younger) all have a mi band 4
