“KURONO TOKYO” has been making waves in the global watch community with every new release. As you all know, it is a watch brand created by Hajime Asaoka, the first Japanese watchmaker admitted as a full member of the Académie Horlogère des Créateurs Indépendants (AHCI).
As an independent watchmaker, Asaoka produces only a small number of watches, and their prices place them beyond the reach of most enthusiasts. KURONO TOKYO, however, was born from his desire to create an unpretentious watch for everyday wear. Its far more accessible pricing is precisely what allows ordinary watch enthusiasts like me to enjoy his work.
Among KURONO TOKYO’s lineup, the model I’d like to discuss today is the brand’s first diver’s watch, the “Diver’s,” which caused quite a stir when it was announced in March 2026. I’m just a humble KURONO TOKYO collector myself, but I was genuinely surprised that their latest release would be a “Diver’s” model. And to top it off, they said , “It’s anything but ordinary”!! (＠_＠;)
Incidentally, this watch possesses an extraordinary feature that I have never encountered even once during the rather long journey I’ve taken to build my modest personal watch collection.
I was invited to the unveiling event for the new 2026 models.
February 28, 2026. I had an absolutely unmissable event scheduled for that day: the “Kurono Tokyo × Hajime Asaoka: ‘Blueprint for Thought’ Special Talk Session, ” to which I had been invited.
People sometimes get the wrong idea, but I don’t actually attend watch events every week. I’d say I get invited about once a month at most. Sometimes people there say, “There you are again!!” to me, but hey, you’re the one who’s “There you are again!!” too, aren’t you?! (lol)
Surprisingly, though, there wasn’t a single familiar face at that day’s event held at the “Kurono Tokyo Aoyama Salon” in Gaienmae. It was actually quite rare—or rather, strangely refreshing!!
That said, many of the participants were “KURONO TOKYO users.” I made a point of actively reaching out to those who owned models I’d missed out on or decided not to buy, in an effort to foster interaction among fans (in fact, I later went out to Omotesando with an American collector I’d become friends with).
The highlight of the day was the “unveiling of the new 2026 models.”The new model that the attending guests had been eagerly awaiting… that would be “Diver’s.” And let me tell you, this is a watch with a truly unexpected and bold design direction… (*´ω｀*)
This Is Not the KURONO TOKYO We Know
I was surprised. I’m sure there were others among the participants who felt the same way I did—namely, “This isn’t the KURONO TOKYO I know!!”
At this point, I think Mr. Asaoka’s strategy had been a resounding success. I’d had opportunities to speak with other KURONO TOKYO fans who were present during previous purchase reservations at the Aoyama Salon, and their reactions were almost exclusively “admiring comments” such as “The finish is beautiful,” “The hands really stand out, ” and “The colour is wonderful.”
When I saw the actual “Diver’s” watch—which could be called the star of the day—I think the people who understood KURONO TOKYO’s history best were the ones who couldn’t hide a certain sense of bewilderment.
Well, that’s to be expected. “This is how KURONO TOKYO should be”… The more someone loves the KURONO TOKYO watch brand, the more they might have felt a “discrepancy between their image and reality” upon seeing the massive 46-millimeter object sitting on the tray in front of them—and perhaps even felt a bit daunted.
But I thought that this reaction might have been exactly the scene Mr. Asaoka wanted to see. It just looked kind of mischievous and fun (*´∀｀*)
I think the event that day was the moment when one of Mr. Asaoka’s endless sources of inspiration was fully unleashed. Even I couldn’t shake off the lingering excitement and bewilderment for quite a while, thinking, “I never imagined I’d see a giant diver’s watch at KURONO TOKYO…”
Inside Those 46 Millimetres Was the KURONO TOKYO We Knew
The American collector, who we hit it off with right there on the spot, placed it on his thick arm several times and smiled, saying , “I’ve got this!!” Meanwhile, those of us with slimmer arms all murmured, “It might be a little too big,” (lol)
However, the moment the “top cover” of the “Diver’s” with its 46 mm Diving Case was opened, the atmosphere among the participants changed in an instant.
From within a case shaped like a diver’s watch emerged the “Cushion Case Dress Watch (35 mm Inner Watch), ” nestled there like a matryoshka doll. That sense of scale, that atmosphere… What lay there was the very embodiment of the refined, contemplative KURONO TOKYO that its devotees envision.
At this point, my interpretation of the “46 mm Diving Case” in *Diver’s* had shifted. I was finally able to accept it as a “transformation and combination set ” centered entirely on the “35 mm Inner Watch.”
With its matryoshka-style design—which allows for a shift in impression that could be described as the complete opposite—the “Diver’s” lets you essentially “enjoy two watches in one.”After hearing that production numbers were even lower than usual, a tense atmosphere of mutual wariness began to spread among the event participants—who were supposed to be fellow enthusiasts… (；´∀｀)
When Good Fortune Arrives All at Once: The Rare Model I Was Lucky Enough to Secure
A few days passed. With the deadline for the pre-order window—reserved exclusively for event participants—fast approaching, I finally submitted my “purchase request.” However, since the production run for this edition of “Diver’s” is even smaller than usual, there’s no guarantee I’ll be able to secure a copy, even with this pre-order.
But didn’t even the legendary pro wrestler “Gokumonki” Masa Saito say it himself? “Go for broke!!” If it doesn’t work out, so be it—all we can do is pin our hopes on the next model.
Just when I was trying to stay humble… I actually “won”!!
It felt as though every piece of good fortune had arrived at once. But as luck would have it, I don’t have the money I need right now (lol).
When it comes to this “Diver’s,” I’ve decided to stretch my budget a little. If I let this opportunity slip by, I’ll never get another chance like this. It’s literally “Go for broke!!” (lol)
So, I’m going to review the new 2026 “Diver’s” model that I was lucky enough to get my hands on, but before I do that!! Please take a look at this “comparison” with the other KURONO TOKYO watches I’ve purchased so far.
Let’s compare them to the “KURONO TOKYO” models I’ve bought so far
Including the “Diver’s,” I’ve acquired a total of “five KURONO TOKYO” watches so far. Every single one of them is a watch that I likely wouldn’t have been able to get my hands on if I didn’t live in Tokyo.
At the same time, these KURONO TOKYO watches also serve as “records” of the fact that, toward the end of my corporate career, I was forced to take a somewhat unreasonable long-term solo assignment. It has a slightly sentimental connotation, but for me, it’s not simply a case of “I bought a watch!!” In the years to come, I’m sure I’ll look at these KURONO TOKYO watches on my wrist and reflect on those times again and again, thinking, “Tokyo was tough… but it was fun, too.”
So, I decided to use No. 3, “Midnight, ” from the “34MM Series” as my point of comparison. It’s the first KURONO TOKYO watch I ever managed to get my hands on—a truly memorable piece.
Comparing the sizes of the “34MM Midnight” and the “46 mm Diving Case (as-is)”
This is quite a sight (lol). Still, the fact that I don’t find myself wondering, “Where’s that huge clock from!?” just goes to show what a pro Mr. Asaoka is. There’s not a hint of inconsistency in his visual identity.
Throughout the design, you can sense the “grammar of watchmaking” that KURONO TOKYO has cultivated over the years. For example, even if you’re encountering KURONO TOKYO for the first time through the “Diver’s” collection, you’ll be able to understand what “KURONO TOKYO” is all about without the slightest misunderstanding.
Comparing the Sizes of the “34MM Midnight” and the “35 mm Inner Watch”
Still, this size really is reassuring. With the “35 mm Inner Watch, ” it looks perfectly natural even when placed next to the smaller “34 mm” model. In fact, the significance of adding KURONO TOKYO’s first “cushion-shaped case”—to a collection that had previously consisted almost exclusively of round cases—cannot be overstated… It has undoubtedly added depth to my collection.
If the watch inside weren’t appealing, “Diver’s” wouldn’t work.
The new “Diver’s” model from KURONO TOKYO 2026 is, compared to previous KURONO TOKYO releases, a watch that is overwhelmingly “driven by a strong conceptual vision. “
The conceptual aspect can also be described as “play.”In other words, “Diver’s” could be described as a “masterpiece born from the unwavering commitment to a sense of play” by Hajime Asaoka—an independent watchmaker and AHCI member (of which there are only a few dozen worldwide), as well as the founder of Tokyo Watch Precision—who never wavered in his dedication to this vision on the KURONO TOKYO stage.
That said, this is an endeavor that puts the “core” of the watch to the test. In the case of this “Diver’s” collection, the “35 mm Inner Watch”—a timepiece built into the outer case—serves as the cornerstone of the project. Both the visual impact of the Diver’s and the pleasure of its transformation are possible only because the “35 mm Inner Watch” at its core has the versatility to carry the entire concept.
A Small Watch Inside a Large Case—or a Large Watch Built Around a Small One?
Whether you interpret it as “putting a large case over a small watch” or “a small watch emerging from inside a large one, ” the context of the “Diver’s” watch changes dramatically. I wonder if the new owners are currently enjoying one of these perspectives—or perhaps both??
As I mentioned earlier, the “46 mm Diving Case” is a component that only truly reveals its purpose when attached to the “35 mm Inner Watch.”
It’s true that housing the “35 mm Inner Watch ” inside the “46 mm Diving Case” results in the explosive debut of the “46 mm Diver’s”—a watch that’s practically a hot topic in itself—but all of this is made possible by the existence of the “35 mm Inner Watch.” I’d like to make it clear right here that the “35 mm Inner Watch” is, without a doubt, the true star of the “Diver’s” collection.
In the next section, I’ll share the features of the “35 mm Inner Watch”—which could be called the “heart of Diver’s”—that really stood out to me.
A Breathtakingly Beautiful Cushion Case
Among the vintage watches I’ve been vaguely thinking, “I’d love to have that, ” for quite some time is a 1970s IWC (Inter) model with a cushion-shaped case (36 mm) powered by the Pellaton-type “Cal. 8541B.” Small-diameter cushion cases have a unisex appeal that transcends gender, don’t they? Similarly, the “35 mm Inner Watch” features soft, rounded lines that look just as good on a woman.
When it comes to cushion-shaped cases, many people might think of Panerai’s “Radiomir.” However, compared to the large 45 mm Radiomir, the “35 mm Inner Watch” is, as its name suggests, a compact case with a width of 35 mm.
I think Radiomir is the quintessential example of a “big but cute watch, ” but in contrast, the “Diver’s: 35 mm Inner Watch” maximises its charm with its small 35 mm size and cushion-shaped case. You’ll understand once you see it in person. It’s the kind of watch that makes you think, “So cute!!” without needing any further explanation.
The smooth, polished finish is another factor that brings out its charm. Even the short lugs… so cute (*´ω｀*)
A Diver-Style Dial That Works in Both Small and Large Cases
The dial features a simple white lacquer finish that is truly beautiful, yet its design also evokes the challenges faced during its development.
After all, there are two different “case sizes”—“small” and “extra-large”—which are key prerequisites in design. I imagine it took a great deal of trial and error to come up with a dial design that works naturally with either size.
The only remnant of that is the “triangle at the 12 o’clock position, ” but what’s interesting is that this actually leads to that “What is this?! This is no ordinary watch!!” reaction when you use it with the “35 mm Inner Watch”!!
When it came to the “46 mm Diving Case, ” there must have been a certain sense of scale that was non-negotiable. Yet, rather than settling for a compromise at the midpoint between large and small cases, Mr. Asaoka took a bold approach by deliberately adopting a triangular design that looks large even at 46 millimetres. As a designer myself, even in a minor capacity, it gave me goosebumps.
Even within the seemingly free-spirited world of diver’s watches, there are certain classics. Many enthusiasts tend to unconsciously use these as a yardstick to judge what’s good and what’s bad… But rather than being bound by such conventions, I believe the dial design of this watch boldly breaks with tradition to create an entirely new balance.
I Love Those Elegant Heat-Blued Cobra Hands
It’s pretty rare to see a “cobra hand” that’s been stripped down this much, isn’t it?? First of all, you might wonder if a cobra hand even goes with the diver’s style when paired with a “46 mm Diving Case”… But it does!! In fact, it looks great!! And it’s refreshing, too!!
Since this watch is (also) designed for divers, it’s essential to maximize visibility underwater; with these “cobra hands featuring a large opening, ” the luminescent properties can be maximized to the fullest. Achieving this must have required a tremendous amount of effort, but KURONO TOKYO refuses to compromise on this point.
The quality of the blue-steel finish is also exceptional, exuding a dressy elegance that one might not expect from a diver’s watch (?). The “calculated balance in the name of imbalance” scattered throughout these details is what underpins the appeal of “Diver’s.”
The Simple Logic Behind the 46 mm Diving Case
The “crown” is the major hurdle in water resistance that all diver’s watches must overcome. The crown is a component that provides direct access to the internal mechanism, and its opening is constantly exposed to the risk of intrusion by liquids and other foreign substances.
Screw-down crowns and applying mechanical pressure to the crown head to enhance the seal—these are all innovations born from the concept that “the crown is essential.” These features have now become standard in diver’s watches.
So, how did KURONO TOKYO’s new “Diver’s” model address this “crown issue”?
Their answer was simple: put the entire watch—crown and all—inside a larger case. (lol)
That’s certainly the quickest and easiest way. With an automatic movement, power is continuously supplied through the motion of your wrist. Even though it’s mechanical, you don’t need to adjust the time all that often. That’s right. This idea of “simply placing the entire watch inside a large case to make it waterproof” isn’t just a “Columbus’s egg”—it’s actually a highly rational solution.
Although this “brute-force” approach is a far cry from the delicate KURONO TOKYO and Mr. Asaoka’s vision, I think it’s the best possible solution for ensuring that no foreign objects can possibly get inside.
With that said, let’s now take a closer look at the “Enhanced Exoskeleton” of the “Diver’s” collection. We’ll delve into the details of the impressive “46 mm Diving Case.”
The “46 mm Diving Case”: Rugged Yet Elegant
The “near-perfect symmetry” achieved by concealing the crown significantly enhances the sense of satisfaction when wearing the “46 mm Diving Case.” This isn’t simply a matter of increasing the size from the “35 mm Inner Watch.” In a sense, it brings the watch infinitely closer to the ideal beauty of an industrial product.
It’s likely that, from the very beginning, the decision to tuck the crown inside the outer case to enhance water resistance—and the resulting “symmetrical” outline of the watch —was a calculated choice.
While it depends on the watch’s design concept, the “symmetrical beauty” achieved by watches that, for example, have the crown recessed into the case, omit the date display, and feature symbolic hour markers is one of those values that transcends time.
From the late Roman Empire through the Byzantine Empire, “divine frontality” was implied in portraiture, including religious art. What was conveyed there was the inescapable message that “a transcendent being is looking at us, ” along with the image of “overwhelming power” emanating from the bilateral symmetry.
Even when fitted with the “46 mm Diving Case, ” the “Diver’s” boasts a divine appearance characterized by its perfect symmetry. The allure radiating from the meticulously polished case suggests that this watch, when worn, is anything but a run-of-the-mill “macho watch.”
I was blown away by the thoughtful details of the “46 mm Diving Case”
Building a stainless steel watch into a stainless steel case… The more you love watches, the more this idea might send a shiver down your spine. “Won’t it get scratched?? ”… It’s no wonder you’d think that way.
Don’t worry!! The inside of the “46 mm Diving Case” is equipped with a “resin insert, “ so unless you handle it extremely roughly, I don’t think the “35 mm Inner Watch” will get scratched.
While waiting for delivery, I, too, was worried about “scratches” that might occur during installation. As a workaround, I even considered, “It might look a bit tacky, but maybe I should put some masking tape on the inside to protect it?” However, now that I see the actual product right in front of me, I can see that there are thoughtful details incorporated throughout the design, so those worries turned out to be completely unfounded.
The “35 mm Inner Watch” protects the easily scratched “lug” and “case back” while securing the watch with a perfect fit—neither too tight nor too loose. For “Diver’s,” where the concept revolves around easily inserting and removing the watch, the resin mounting base might just be the most important component—even if it’s often overlooked. After all, if there’s any friction here, the whole thing is pointless.
What a Feel: The Ultra-Strong Duralumin Unidirectional Bezel
The “46 mm Diving Case” features a component that combines a rotating bezel and a crystal to serve as a “lid.” Screwing this component in place with the dedicated opener ensures sufficient water resistance, but what truly stands out about this part—more than its functionality—is its stunning visual appeal. In fact, I fell in love with this “red bezel” and decided to buy it.
The material is “extra-super duralumin, ” which boasts top-class strength among aluminum alloys. I remembered writing about this in my main line of work, so I looked it up—and wouldn’t you know it, this is the very material that was used to reduce the weight of the Zero fighter. This material, steeped in such history, has been finished in a sophisticated red using “hard red anodising, ” which also serves as rust protection. I think one of the charms of this bezel is that you can still sense a hint of the metal’s “raw texture.”
By the way, the watch crystal is made of “sapphire crystal.” Since the crystal consists of two layers when used as a diver’s watch, a crystal with high transparency is essential.
5 atm ⇒ 10 atm ⇒ 300 m: Water resistance takes a step up with the “46 mm Diving Case”
It is clearly overkill for city dwellers, but that excess is precisely the romance of overengineering. It’s not a matter of “I don’t need it because I won’t use it.” After all, a samurai doesn’t carry his sword just to draw it indiscriminately.
It’s all “for that moment”… I know this all too well, having let my 100-meter water-resistant watch get submerged during Typhoon No. 21 in 2018, which caused massive damage in Osaka. Even if you live in a city, the higher the water resistance, the better.
In the case of the “Diver’s,” the inner watch alone is water-resistant to only “5 atm.” As for whether it can be used on days with heavy rain and strong winds, its performance is a bit questionable.
That’s where the “46 mm Diving Case” comes in—simply closing the “lid, ” consisting of the rotating bezel and crystal, by hand provides “10 bar of water resistance.”Furthermore, by using the dedicated “DUOSEAL” opener to secure it tightly, the water resistance is enhanced to “300 metres.”
According to tests conducted by a public agency, it withstood pressures equivalent to a depth of “500 metres,” clearly demonstrating the high potential of the “46 mm Diving Case.”
For people in the Kansai region, the scenes they witnessed during Typhoon No. 21 in 2018 were truly traumatic, but with the “Diver’s” equipped with the “46 mm Diving Case,” it wouldn’t let water in easily—even amid that pounding rain and strong winds that snapped tree branches. After all, there’s no exposed crown. So you won’t have to worry about accidentally turning the crown in the rain and thinking , “Oh no!! I’ve let water get inside!!”
I Tried Submerging the “Diver’s”!!
Actions speak louder than words. Just submerge it in water!! … So, I filled a fancy glass container with water and submerged “Diver’s” in it. I can’t believe I, of all people—a total scaredy-cat—did something like this… I just wanted to see it for myself : “Diver’s” holding its breath underwater.
It’s said to be “water-resistant to 300 metres” when closed with the dedicated opener, and “equivalent to 10 bar of water resistance” when closed by hand, but what I really want to know is the “peace of mind” that comes with closing it by hand. It’s a hassle to carry the opener with me every time I wear the watch, and I believe that performance within the range achievable by hand is the true measure of a daily-wear watch.”
It’s not exactly under water pressure—it’s more like a budgerigar taking a bath—but it seems like it should at least serve as a test simulating heavy rain. The result was that it demonstrated “sufficient water resistance even when closed by hand.”
A slightly luxurious Japanese-made watch featuring Miyota’s “Cal. 90S5”
The “Diver’s” is powered by Miyota’s premium-line “Cal. 90S5” automatic movement. It operates at a frequency of 28,800 vibrations per hour, with an accuracy of -10 to +30 seconds per day. The power reserve is approximately 40 hours.
The most important feature of this “Diver’s” model is, above all, that it’s an “automatic winding” watch. After all, once it’s sealed inside the outer case, you can’t wind it using the crown. It also needs to be accurate enough that you don’t have to adjust the time frequently.
In that regard, you won’t have any practical concerns with Miyota’s 9000 series. I think Miyota’s recent models—especially the 9000 series—offer outstanding reliability. All of my 9000 series watches are still running strong.
The “Leather Strap” That Remains in the Shadows
Once I get my KURONO TOKYO, there’s one thing I have to do right away… I just can’t help but want to change the strap. When you get a nice watch, you just want to “treat it to a new strap”… That’s normal, right?? Huh?? Am I just a pain in the neck??
To me, a watch strap is a “partner that should be on equal footing with the watch itself.” That’s why standard straps—which play a subservient role, like the saying “stand three steps back so as not to step on your master’s shadow”—just don’t cut it in terms of visual balance. This isn’t limited to KURONO TOKYO, but as a matter of fact, all of my KURONO TOKYO watches have been fitted with third-party straps.
However, when it comes to this “strap for the 35 mm Inner Watch, ” I feel like it’s fine to leave it in its standard state for the time being.
There’s no clear reason why I can say , “This is it.” But for some reason, among all the standard straps I’ve seen so far, this one feels like the best fit. Perhaps it’s because its extremely simple, understated presence—like a “shadow”—pairs perfectly with the “35 mm Inner Watch, ” which is as modest as the chestnuts in a chestnut manju.
By the way, the strap is fitted with quick-release spring bars, making it easy to change without tools.
The Rubber Strap Is Exceptionally Well Made
Of particular note is the “rubber strap” that comes with the “46 mm Diving Case. “
If I’m going to replace it, I’ll probably need to use Arc Fit around the lugs to make it look like it’s part of the case. Now, which strap manufacturer am I going to make suffer with this troublesome order? (lol)
But to be honest, when it comes to this rubber strap, I’m thinking, “Maybe I’ll just keep it like this until I get tired of it.” How should I put it… To be completely honest, I really like it (*´艸｀*)
The fact that it secures a massive 46-millimeter chunk of metal to your wrist without it shifting around is a testament to the excellence of the design itself. The extra-thick rubber strap distributes the “total weight when wearing the 46 mm Diving Case” across your skin, so the watch face won’t slip even if you don’t tighten the strap all the way.
The larger the watch, the more important the strap’s “securing performance” becomes—and in that regard, this rubber strap gets a perfect score. At least on my wrist, which has a circumference of just under 17 centimeters, this massive “46 mm Diving Case” doesn’t budge an inch. Despite its understated appearance, I think it’s actually a high-quality rubber strap.
A Clever Way to Switch Between Two Very Different Straps
The “shock and surprise” of seeing a watch’s size and appearance change so drastically is certainly intense. However, there’s also an irresistible charm in the idea that—by wearing a strap that’s clearly different from the one I was wearing just moments ago—I’m essentially wearing the same watch, revealing a “tricky and eccentric side of myself.”
Although you’ll need to carry the “35 mm Inner Watch Strap” with you at all times, the transition from an extra-thick rubber strap to a classic strap is, quite simply, “a whole different ballgame.” Naturally, this makes for an experience that’s fundamentally different from the “usual strap swap” for the same watch. Even from the perspective of the strap alone, the “Diver’s” concept is this fascinating. I have a feeling that the more I use it, the more it will delight me with fresh new perspectives.
A Delightful Contradiction: The KURONO TOKYO Diver’s
I keep my “beloved KURONO TOKYO watches” in CELIEU’s “Pelican Watch Case.” It’s a spacious case that holds five watches, so even if I fill it with nothing but large watches, they won’t bump into each other and scratch one another. It’s really well-made, you know.
So, what do you think?? This “overwhelming sense of something being off”… That’s right. This is exactly the scene I wanted to see!! (lol)
This latest “Diver’s” model, with its intriguing design features, has attracted significant attention even from those who aren’t long-time KURONO TOKYO fans. However, it may be the “longtime fans”—those who have followed KURONO TOKYO’s journey up to this point—who are truly impressed by this model.
This is because “Diver’s” is a “paradoxical conjunction” that has suddenly been inserted into the past, present, and future of the story that has shaped KURONO TOKYO. For those already familiar with the classic KURONO TOKYO, it likely felt like a powerful “but” or “however” that completely transformed the brand’s worldview.
And this is precisely what gives “Diver’s” the context of “Special KURONO TOKYO.” Mr. Asaoka’s “giant KURONO TOKYO, ” presented with “unbridled playfulness.” How to perceive and enjoy this paradoxical creation… It’s rare to come across a watch that challenges the wearer’s interpretive skills to this extent.
It’s impossible to know what’s stuffed into Mr. Asaoka’s invisible four-dimensional pocket. However, this will surely leave fans once again wondering , “What kind of KURONO TOKYO will we get to see next?”—spending their time caught between anticipation and anxiety. Yes, without a doubt (；´∀｀)
