It’s weirdly nostalgic to think about now. Back in 2016, the hype for Pokémon Sun and Moon was absolutely off the charts. We were moving away from the grid-based movement of the 3DS era into something that felt like a real, breathing world in Alola. But then Nintendo and TOMY did something specific. They released the Z-Ring, or what most of us just called the Pokémon Sun Moon watch.
It wasn't a watch in the sense that it told you the time or tracked your steps. Honestly, it was a chunky piece of plastic that sat on your wrist and made a lot of noise. But for a specific window of time, it was the coolest peripheral in the world.
What the Z-Ring Actually Did (and Why It Wasn't Just a Toy)
Most people assume these plastic add-ons are just standalone roleplay toys. You know the ones—you press a button, it lights up, and that’s the end of the interaction. The Z-Ring was different because it actually "listened" to your 3DS.
Using high-frequency sound signals that the human ear can't really pick up, the game would trigger the physical Pokémon Sun Moon watch on your wrist. If you used a Z-Move in the game, the bracelet would vibrate, flash colors matching the move type, and play the specific sound effects of that move. It was haptic feedback before we really called it that in the mainstream.
It felt tangible. When Pikachu used Gigavolt Havoc, your wrist would explode in yellow light. That physical connection to a digital move was something Nintendo hadn't really mastered until that point. Sure, we had the Pokéwalker back in the HeartGold days, but that was a pedometer. This was an immersive battle accessory.
The Technical Wizardry Behind the Plastic
How did it work? It’s actually pretty clever.

The Z-Ring didn't use Bluetooth. That would have drained the 3DS battery and made the toy way more expensive. Instead, it used "chirp" technology. When the game reached a certain animation frame, the 3DS speakers emitted a specific audio code. The small microphone inside the Z-Ring caught that code and translated it into a light and vibration pattern.
Compatibility and Crystals
You couldn't just use one move. The whole gimmick was based on Z-Crystals.
- You’d buy these little physical crystals.
- You’d snap them into the bracelet.
- The bracelet would recognize which crystal was inserted.
- If you had the Fire-type crystal (Firium Z) in, the bracelet glowed orange.
It was a brilliant bit of merchandising by TOMY. They sold the Z-Ring with a few crystals, but if you wanted the full set to match your in-game Z-Move library, you had to buy expansion packs. It’s the kind of thing that makes parents roll their eyes but makes a ten-year-old feel like an actual Alolan Trial Captain.
The Pokémon Sun Moon Watch in the Modern Era
If you try to buy one today, it's a different story. These things have become collector's items. Finding a Z-Ring (or the later Z-Power Ring from Ultra Sun and Ultra Moon) in good condition with all the crystals is surprisingly tough.
Why do people still want them? Because they actually work with the games still. If you pull out your old 3DS right now and fire up Pokémon Sun, that Z-Ring will still react to your moves. In an era of digital-only content and "live service" games that eventually shut down their servers, there’s something refreshing about a physical toy that still "communicates" with a handheld console from a decade ago.

There's also the Pokémon POKKÉN TOURNAMENT DX factor. On the Nintendo Switch, you could actually use the Z-Ring with the fighting game. It was one of the few pieces of hardware that bridged the gap between the 3DS and the Switch era.
Common Misconceptions About the Device
A lot of people think the Z-Ring was required to use Z-Moves in the game. That's totally false. You could do everything in the game without spending a dime on the toy. The toy was purely "4D" flair.
Another weird myth was that it worked with the anime. Actually, it did! If you were watching the Pokémon Sun & Moon anime in Japan (and certain other regions), the broadcast would occasionally trigger the Z-Ring during battle scenes. It was a massive cross-media push that we don't see as often anymore.
Is It Worth Picking One Up Now?
Honestly, it depends on how much you love Alola.
If you are a hardcore collector, the Z-Power Ring (the black version) is the one to get. It has a larger library of sounds and works with more moves. But if you’re just looking for a piece of Pokémon history, the original white Pokémon Sun Moon watch is the classic.

Just be prepared for the noise. It is loud. Very loud. And there is no volume knob. You are either fully "Z-Move energized" or you are silent. There is no middle ground.
Steps to Get the Most Out of Your Z-Ring
If you've managed to snag one from an auction site or found yours in a basement box, here is how to make sure it actually works.
Check the battery compartment immediately. These toys used AAA batteries. If they’ve been sitting since 2016, there is a 90% chance the batteries have leaked. Use a little white vinegar on a Q-tip to clean off any blue or white crusty acid from the metal contacts. If you don't do this, the Z-Ring won't turn on even with fresh batteries.
Calibrate your 3DS volume. Since the Z-Ring relies on sound, you can't play with headphones if you want the watch to react. You need the 3DS volume at least at 70%. If the room is too noisy, the microphone in the bracelet will get "confused" and might not trigger the lights.
Update your crystals. Remember that the physical crystals don't actually "contain" data. They just have different plastic notches that tell the bracelet which LED sequence to play. If your bracelet isn't lighting up the right color, check to see if the crystal is seated properly. Sometimes a little dust in the slot prevents the sensors from reading the notches.
Verify the Game Mode. The Z-Ring has two modes: Role Play and 3DS Link. If you have it in Role Play mode, it won't listen to your game; it’ll just react when you press the button. Switch it to the 3DS icon (usually the second click on the power switch) to get the sync working.
The Z-Ring remains a fascinating relic of a time when Pokémon was experimenting with how to bring the digital world into our physical rooms. It wasn't perfect, but it was ambitious. And in the world of Pokémon collecting, ambition is usually what makes a piece of plastic worth keeping.
