Something that big and heavy on a kid's arm is going to get uncomfortable after like ten minutes.
One watch, the Garmin Bounce, weights 37.2 g. https://www.garmin.com/en-US/p/714945#specs
Hardly heavy.
I have a Pixel Watch that's about that size (36g IIRC), and I don't like wearing it, and I'm a grown adult.
I got my kids cheap Casios, and they're like 20g. Way better.
