In this short video Eon holds up one of his favorite things and gives it a full review: his CASIO Tough Solar watch. He runs through what makes it special — it's tough, it's water resistant, and best of all it's solar. Then he does two hands-on things on camera: he reads the time off the face, and he flips on the little light. Let's follow along.
"It's solar" — a watch that drinks light
Eon keeps coming back to one word: "it's solar, so it's really good." That's the star of the show, so what does it mean?
Most watches run on a tiny battery that eventually dies, and someone has to pop the back off and put in a new one. A solar watch is different. A little solar panel sits right on the watch face. It soaks up light — bright sunshine or the light in your room — and turns that light into electricity to run the watch. As long as it keeps seeing light, it keeps going. No battery to replace, ever.
It's the same trick as the big solar panels people put on rooftops, just shrunk down small enough to ride on your wrist.
Reading the time: count to twelve
Here's the best teaching moment in the whole video. Eon presses a button and starts counting out loud around the watch: "1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12." Then he announces the answer — "it's 12 o'clock, 12 p.m. right now."
That counting isn't random. He's showing you exactly how a clock face works:
The numbers 1 through 12 go all the way around the circle. To read the time, you find where the hand points and count around to that number. When you land on 12 at the top, it's twelve o'clock. And 12 p.m. has its own name you might know — noon, the middle of the day.
So Eon just turned "what time is it?" into a little counting game. That's a skill you can practice on any round clock in your house.
Tough, water resistant, and a light for the dark
The watch is called "Tough" Solar, and Eon explains why: "it's tough, so it's really tough to break — no problem." He also points out it can handle water.
Tough means it's built to survive bumps, knocks, and drops without breaking — handy for a kid who's always busy. Water resistant means a splash or rain won't get inside and wreck it. (Water resistant is the honest word — it shrugs off splashes, but it's not made for deep diving.)
Last, Eon shows the backlight. He turns it on and says, "this is strong… a little bit… but it's not as strong." That's a great honest review:
A backlight glows behind the screen so you can read the time in the dark. Funny, right? A watch that needs light to charge can also make a bit of its own light to be read. Eon noticed it's not super bright — and that's a real, useful thing to notice about your gear.
Try it
Find a round clock — on a wall, a microwave, or even drawn on paper. Pick a number and, like Eon, count out loud around the face until you reach it. Where's 12? That's twelve o'clock. Then hunt around your home for something solar — a calculator, a garden light, a solar watch. Cover its panel with your hand, then uncover it, and watch it wake up with light. That's solar power working right in front of you.
