Casio G-Shock Nano: The Iconic Watch Shrunken to Finger Size

Casio shrinks the iconic G-Shock DW-5600 into a finger-sized ring watch. Meet G-Shock Nano—features, price, and why it’s the coolest gadget of 2025.

Have you ever looked at something you love and just thought, "I wish a tiny version of this existed"? Well, if that thing happens to be the legendary Casio G-Shock, you’re in for a treat.

Casio G-Shock Nano: The Iconic Watch Shrunken

Casio has been on a roll with its quirky, miniature timepieces lately. I’m sure some of you remember when they dropped that series of ring watches—literal jewelry with tiny, functional watch faces. I even wrote about their Casio Gold Ring Watch before; it was a stunning piece, but let's be honest, that much "gold" might be a bit out of reach for many of us.

But now, Casio is bringing that same wild idea to its most beloved, rugged brand. Get ready for the Casio G-Shock Nano DWN5600-1.

It’s a G-Shock, But for Your Finger

That’s right, folks. Casio took one of its most iconic models, the DW-5600—the square-faced G-Shock that everyone knows and loves, and zapped it with a shrink ray. What you get is a fully-formed, finger-sized version of that classic, ready to add a dose of retro flair to your hand.

What’s really cool is how they designed it. Unlike some of Casio's previous ring watches that used a solid, fixed-size band, the G-Shock Nano has a miniature strap and buckle. Just like its big brother! This is a huge plus in my book, as it means you can actually adjust it to fit your finger perfectly, instead of having to guess your ring size and hope for the best.

The Nitty-Gritty: It's Tiny, But Does It Work?

So, how small are we talking? According to Casio, the G-Shock Nano is about 1/10th the size of the original DW-5600. Just think about the engineering challenge that must have been!

Now, you might be wondering if a screen that small is even useful. While they couldn’t squeeze in the exact same multi-function display layout as the full-size watch, it absolutely shows the time clearly. And let’s be real, that’s the main job, right?

Amazingly, they even managed to recreate the four function buttons on the sides. They’re ridiculously tiny, but they are fully functional. One button activates a small pulsing light for checking the time in the dark (a classic Casio feature), while the others let you cycle through modes and adjust the time and date.

And yes, it still packs in the core features you’d expect:

• Dual time
• Stopwatch
• Auto-calendar

So, it’s not just a look-alike; it’s a genuine, functioning Casio timepiece.

A True G-Shock in Miniature? You Bet.

Okay, here’s the part that really blew my mind. Casio claims the G-Shock Nano has the same shock resistance and 200-meter water resistance as a standard G-Shock.

Read that again.

You can, theoretically, get just as rowdy and adventurous with this tiny ring watch as you can with a full-sized one. I’m not sure I’ll be deep-sea diving with it on my finger anytime soon, but knowing it can handle a day at the beach or an accidental drop is seriously impressive.

They also made a practical improvement on the battery front. Remember how some of the older ring watches required you to basically disassemble the front module to swap the battery? Not here. The G-Shock Nano has a proper case back held in with four tiny screws, just like a traditional watch. You’ll probably need to channel your inner watchmaker with a miniature screwdriver, but it’s a much more user-friendly design.

Sizing, Colors, and What’s in the Box

The watch case itself measures just 23.4 x 20 x 7.5mm, making it small enough for most fingers without feeling too bulky. And since it wears like a watch with that adjustable band, fit shouldn’t be an issue for anyone.

To kick things off, Casio is releasing the G-Shock Nano in the three most popular colors from the DW-5600’s history:

• Classic Black
• Daring Yellow
• Bold Red

As a final neat touch, each ring watch comes packaged with its own tiny silicone stand. So when you’re not wearing it, you can prop it up on your desk or nightstand like a miniature piece of pop-art.

The Final Verdict (and the Price)

The Casio G-Shock Nano DWN5600-1 is listed as "coming soon" on Casio's website, with a price tag of $110. For more information, head over to Casio's official website.

So, what’s the verdict? It’s undeniably cool. It’s a perfect blend of nostalgia, novelty, and genuine G-Shock toughness. It is the ultimate conversation starter and a must-have for any die-hard G-Shock collector or anyone who just loves wonderfully weird gadgets.
