Apple Watch not showing up in "Batteries"

When looking in that area, check to see if in the upper right corner of the widget do you see the words Show Less, or Show More. If you see Show More, then it is possible it is just hidden. If that isn't the issue, then try removing the widget, restart your phone, then add it back again.

Hello, I see this occasionally as well. Sometimes it just needs an extra bit to load. If it happens frequently you might try rebooting your phone. Just hold down the power button, and then slide the power off bar when prompted. Power your phone back on, and I think that will sort the problem. I hope that helps!

You're welcome. Enjoy!
