It lights up, he can put it on and off himself, and he doesn't have to keep asking an adult to reset it..... our 5 year old is happy.  He's just starting to tell time so we got this for his birthday and he was very excited.  He wears it daily and we don't have to worry about water/sand while he plays "adventure" outside.  I wish they sold this in another color and we'd get this one to replace the teaching one with a stretchy band we got for his sister.
