The best G Shock for smaller wrists – now that’s a term I’ve searched countless times. You might not know this but the first watch I bought with my own money was the DW5600-MS1. I just thought the negative display was the coolest thing in the world. And also it was the only thing I could afford as a high school kid. I soon learned about watch sizes and a 43mm chunky square made it seem like I just broke out of prison. It looked like an ankle monitor on my wrists. And since then? I’ve been journeying to find a G Shock for smaller wrists.
Believe me, I tried everything. By everything, I mean buying up loads of Baby Gs because those were the only sizes that’d fit. But they are seriously made for kids, and the color schemes and designs aren’t exactly very “tough” in my book. So after a while, I figured there would never be a G Shock for smaller wrists, and I gave up. Then, recently, I discovered a relatively new tough solar release that came in an acceptable case size of 41mm.
Eventually, I came across a deal good enough that I couldn’t pass up. And here I am with the perfect G Shock for smaller wrists. My prayers have finally been answered with the GST-B600. I’ve worn it every day for the past few weeks and it’s a keeper.
History of G Shock
The G Shock that is now known worldwide began with Kikuo Ibe, Casio’s head of watch design back in the 1980s. Known as the father of G Shock, Ibe dropped his family heirloom mechanical timepiece and became determined to create an everyday “tough” watch. The goal was simple, three design thresholds, the so-called“triple 10”. It had to survive a 10-meter fall, at least 10 ATM of water pressure, and at least 10 years of battery life.
Ibe assembled a team of three known as “team tough” and went on to produce at least 200 prototypes before their Eureka moment. It came in the form of observing a rubber ball bouncing in a playground where he noticed that the center of the ball takes no impact. Shortly after, in 1983, the first G-Shock, the DW-5000C aka the “square” was born.

G Shocks weren’t very popular during their early days as people preferred analog dress watches. Thus began a series of advertising campaigns involving experiments on live television. It started with smashing G Shocks with a hockey stick. In 2017, Casio was awarded the world record for the heaviest vehicle to drive over a watch when the DW-5600E survived a 24.97 tonnes truck.
From the US Navy to musicians like John Mayor, G Shocks have found themselves on various wrists. With arguably the largest watch catalog worldwide, they finally have one for smaller wrists. And it’s packed with all the cool features and quirks.
Welcome to the SIXIW family, the GST-B600. Without a doubt, it’s the best G Shock for smaller wrists.

Case
Where do we even begin? I’m smitten by the royal oak-like case shape; the way each part integrates is silky smooth while being rugged. The two-part stepped-bezel construction is secured by bold front screws and is finished with a multitude of polishing techniques. At the base lies the ever-so-familiar resin material that gives every G Shock its rugged structure. All finished off with a brushed stainless steel caseback letting you know this G Shock stands on business. As always, the four buttons and their labels are large and easy to operate, which is fantastic for those with fidgety hands.

One immediately apparent thing is how compact and slim the entire case is. I didn’t think I’d ever call a G Shock slick, but here we are in 2024 with one of the cleanest analog/digital sports watches. Yes, I’ve just called it a sports watch, because that’s exactly what the GST-B600 is. Since everyone is onboard the integrated bracelet sports watch hype train, here’s one that’s characteristically sports. Whatever sports you’re into, chances are it’ll survive anything you throw at it, and all the while, it will make you look good.

Look I’m shocked (oops) that Casio may have just given us the watch of 2024; it’s truly that good. I have a soft spot for well-designed integrated watch cases, not looking at you, Tissot PRX. The GST-600B here combines everything we love about a metal sports watch with the integrated nature of G Shocks. What more are you after?
Dial & Hands
A lot is happening on the dial; it’s complicated and it’s bold. But that’s part and parcel of a G Shock. They’re supposed to be the Swiss Army Knife of watches – lots of functionalities packed into an indestructible object. You immediately notice the 3D depth with all the different sections. At the deepest level, the rectangular cut-out LCD screen can be adjusted to rotate between a seconds-timer, day, date, and digital time. I will say it’s rather small and while unobtrusive, it’s hardly visible with the negative display. However, it does give off “stealthy vibes” which is always a plus for me.

You’ll immediately notice the raised rectangular bars in a brushed matte black state. Surrounding the dial are 3-dimensional applied stainless steel indices that play with the light ever so slightly. The applied indices aren’t lumed, but they’re reflective enough for you to notice them in darker environments. I mean, you could just light up the entire dial with the torch functionality. Speaking of, the light sits inside the 9 o’clock index and uses the reflective nature of the indices to light up the rest of the dial.
I do have one complaint…
But why all the text on the dial? That’s my one true complaint as they could’ve made it sportier and less tacky without all the text. If they ever create a relatively sterile version of the GST-B600? We could be looking at the best-looking G Shock for smaller wrists or any wrists ever created.
Resin Strap
I love the resin strap; it’s extremely soft and supple. The way Casio has designed it to integrate with the case also deserves praise. In most cases, an integrated bracelet watch always has the strap extending outwards, resulting in an unruly lug-to-lug distance. Another minor detail that makes or breaks an integrated bracelet or strap is how much it angles downwards and hugs the wrist. Like any other G Shocks, the strap is perpetually curled and ready to hug any wrists, and that’s a real difference maker.

Speaking of integrated, Casio has done a fantastic job matching the resin mid-case to the strap. The GST-B600 looks like a one-piece resin strap + case with a metal bezel and case back attached to it. It’s quite difficult to explain through words, but kudos to Casio. I should also mention there is an option to go with the bracelet, but I’m much more of an integrated strap person myself. Besides, I feel the bracelet version lacks character.
Comfort & Wearability
Calling it the best g shock for smaller wrists is nuff said for this section, but I’ll do my best to explain why. First, the thinness of the GST-B600 is unbeatable at just over 11mm in overall height. Accompany the slimness with a compact lug-to-lug of 42mm and you’ve got 90% of the ingredients for a watch for small wrists. Then, you add the fact that 30% of the 41mm case diameter is the metal bezel. Oh and the GST-B600 weighs no more than 60g.
The dimension of the GST-B600 screams “built for tiny wrists”, and boy does it do an excellent job on the wrist. Don’t get me wrong it has that traditional G Shock wrist presence, but without the size and the weight. Again, it’s sleek, sporty, and anything but tacky and bulky. It’s just so comfortable on my wrists and as far as G Shocks for smaller wrists go, they don’t get any better than this.

I’ve had the GST-B600 for about 3 weeks now and I have been wearing it everywhere I go. Regardless of the outfit or the event, the G Shock is coming along for the ride. And I must say, it’s extremely versatile, which is something no one ever says about a G Shock. The best part is I don’t ever have to worry about damaging it. Instead, I have to be careful not to damage things that I accidentally hit the BST with.
Best G Shock For Smaller Wrists

Technically, the GST-B600 is one of like, five options when it comes to a G Shock for smaller wrists. Seriously, us enthusiasts with tiny wrists aren’t given a buffet of G Shocks and we’ve been constantly under Casio’s mercy. It doesn’t even make sense considering Japanese wrist sizes aren’t exactly large either so why the 50mm mudman? Anyway, say Sayonara to all the Baby-G’s you’ve been on the fence about. Goodbye and farewell to the ladies’ 38mm G-Shock square that doesn’t have all the higher-end functionalities and build.
If you’ve been wanting a G Shock and you’ve got small wrists? The GST-B600 is your answer and you better go get one now.
Casio GST-B600: Closing Thoughts
Aesthetics: It might not be everyone’s cup of tea, I can see how some might see it as a conflicting watch. For me, it’s a sporty G Shock that truly is a mixture of form and function. If you’re into G Shocks, you’ll love the GST-B600.
Comfort: The GST-B600 seriously wears like a 39mm watch. Don’t let the 41.4mm case diameter fool you, it’s lightweight, thin, and extremely comfortable on wrists.
Price: At around USD $300, it’s by no means an affordable G Shock, but for the watch that you’re getting? It’s worth the extra money.
