Kids smart watches

Hey All,
Does anyone have a kids smart watch that they love?
Mr. 9yo wants a phone of course, but he wont be getting one for a few years yet.
Looking for a watch that he can call/recieve calls from selected numbers. Set up 'school time' so no calls during this period.
And have a decent GPS?
Little man has started struggling with behaviours, one of which is absconding, so want this for piece of mind and a great Xmas present
