Kurono Tokyo Malachite Review: Why It Excited Collectors?
Berk OztoprakAuthor
At first glance, the Kurono Tokyo Anniversary Malachite might appear to be a new limited edition with a green dial. But the real point of this model is not the color, but the layers. On one side, there's Hajime Asaoka's watchmaking language, close to Art Deco, restrained and almost graphic in its design precision. On the other, there's the completely uncontrollable malachite texture of nature. This is where Kurono's unique approach begins. For years, the brand has captivated collectors with its use of color, proportion, and the idea of accessible, independent watchmaking. The Malachite, however, takes this formula to a more material-focused, more risky area. According to the official website, the model features a 37mm steel case, a Miyota 90S5 automatic movement, and a malachite-centered convex dial.
Kurono Tokyo Malachite Review: The Silent Tension of the Stone Dial
TL;DR
- Kurono Tokyo Malachite is a limited edition Anniversary/Special Projects model that uses real malachite in its center.
- Its strongest point isn't the technical complexity, of course. But the dial material, the balance of proportions, and Asaoka's color philosophy make it incredibly powerful.
- With its 37mm case, Miyota 90S5 clasp, and 3 ATM water resistance, it has more of a dress-watch character.
- Interest from collectors may be high.
Why is Kurono Tokyo Malachite being talked about?
What's noteworthy here is that the Kurono Tokyo Malachite isn't just a model added to the gemstone dial trend. Kurono uses malachite in the center of the dial while creating color continuity with a brass ring and rokusho/verdigris green on the outside. In Hajime Asaoka's official statement, this choice is attributed to the idea of a pigment that shares the same copper origin as malachite. Therefore, green isn't just a visual decision, but a color architecture conceived through material kinship.
From a design perspective, the unique observation is this: This watch consciously creates a tension between the randomness of the natural stone and Kurono's obsession with linear order. The uncontrollable nature of the malachite pattern slightly loosens Kurono's usually very restrained dial aesthetic. This is a good thing, because one of the brand's most appealing aspects in recent years is its ability to create a strong visual character within a small case.
Kurono makes a malachite move on the Tokyo Anniversary line.
Kurono Tokyo Anniversary models are often read more as small manifestos, showing which aesthetic idea the brand is highlighting that year, rather than just an anniversary calendar. A similar situation exists for Malachite. The brand states that the model will go on sale on May 28, 2026, with two online ordering windows, a price of US$1.850 excluding taxes and import costs, and a limit of one unit per customer. Deliveries are expected to begin from the end of June 2026.
From a collector's perspective, the answer should be clear. Kurono is still one of the brands that skillfully balances supply and demand in the accessible independent watchmaking space. Time and Watches associates Kurono with Hajime Asaoka's aim to bring his high-end design DNA to a more accessible price range. Monochrome also emphasizes Asaoka's place in Japanese independent watchmaking and Kurono's offering a more accessible design universe with outsourced movements.
Design: not the romance of green, but a controlled scene.
There's always a slight risk with malachite dial watches. If the material is too dominant, the watch approaches a piece of jewelry. If it's too tamed, the meaning of using a stone dial diminishes. Here, Kurono creates a more stage-like arrangement by framing the central stone texture with the brass section on the outer edge. The kanji zodiac indices are also part of this frame that carries cultural references, not just decorative elements.
I think the real point here is that the watch seeks luxury not in the complications, but on the surface. The Kurono Tokyo Malachite doesn't showcase a chronograph, calendar, or special mechanism. Instead, it wants the gaze to return to the center of the dial every time. This is a technically simple but visually intense approach.

Kurono's website lists the Miyota 90S5 as having 24 jewels, a frequency of 28.800 vph, and approximately 40 hours of power reserve. Miyota's own technical datasheet gives approximately 42 hours of runtime for the same movement. This small difference isn't a major discrepancy, but it's more accurate to mention the difference in power source in the technical specifications.
Technical side: a seemingly small but important choice.
On the technical side, a seemingly small but important detail is the 37 mm case size. Today, gemstone dial watches often rely on larger diameters to enhance visual impact. However, the Kurono remains compact despite the opulent potential of its dial material. This elevates the Malachite from a colorful display object to a more everyday dress-watch.
The choice of the Miyota 90S5 also summarizes Kurono's product positioning. This watch doesn't claim to be haute horlogerie based on its movement. The movement is reliable, relatively thin, high-frequency, and understandable in terms of serviceability. The real budget and attention seem to be dedicated to dial production. The fact that the official website points to a high waste rate in the production of malachite discs indicates that in this model, the value lies more in material processing and selection than in mechanical complexity.
Who is it suitable for?
The Kurono Tokyo Malachite is meaningful for collectors who appreciate small cases, have an interest in Japanese independent watchmaking, and see the dial material as the main character of the watch. It is a strong candidate, especially for those who follow the Kurono Tokyo style but expect a more material-focused piece from the brand.
It has an understandable appeal even for watch enthusiasts who aren't engineers. You don't need to be familiar with the movement architecture to see the value of this model. The proportions, colors, dial texture, and limited production history are immediately apparent.
Limitations / points to consider
This model isn't equally suitable for everyone. 3 ATM water resistance places the watch more in city/dress use. It might be limiting for those with high expectations for everyday durability. Even though it aligns with the dress character, a slightly higher water resistance would have been better for us watch enthusiasts.
The second issue is the purchasing conditions. Kurono explicitly states that due to limited production and high demand, cancellations/returns are not accepted. Therefore, the Malachite is more for the collector who already knows the brand and its dimensions, rather than for the convenience of seeing it and deciding on it in person.
The third point is the nature of the natural stone dial. No two pieces will look the same. This can be an appeal for collectors.

Conclusion: interesting not because it's beautiful, but because it's well-arranged.
The breaking point of the Kurono Tokyo Malachite is this: the watch doesn't just use malachite as a luxurious green gemstone, it disciplines it with Asaoka's restrained dial language. Technically, it's not revolutionary, and in fact, it's quite pragmatic on the mechanism side. But when design, materials, and collector psychology converge, it creates a powerful example of why Kurono is still talked about today.
If you'd like to take a broader look at the Kurono universe, Bersenti's review of the Kurono Tokyo Grand Jubilee Calendar , the Kurono Tokyo story and collection , and the guide to Japanese watch brands offer a good starting point. When evaluating a Malachite, the healthiest starting point is not just asking "Do I like it?", but "Does this watch's character truly hold a special place in my collection?"
