G-Shock's MRG-B2100HR: A $7,000 CasiOak That Blurs the Line Between Watch and Work of Art
There are anniversary editions, and then there are statements. Casio's new MRG-B2100HR-1A — built to celebrate three decades of its MR-G flagship line — falls squarely into the second category. It takes the beloved CasiOak silhouette, long one of the most recognized shapes in modern watchmaking, and elevates it into something that belongs in a museum case just as comfortably as on a wrist. We're talking platinum leaf applied by a Kyoto master, structural iridescence conjured by precision laser at the micron scale, and a production run of exactly 800 pieces worldwide. If you thought you had G-Shock figured out, think again.
The MR-G Legacy: Thirty Years of Luxury Under the G-Shock Banner
Most people associate G-Shock with indestructibility on a budget — the $99 black-resin beater that laughs at mud, saltwater, and concrete. That reputation is well earned. But it has always obscured a quieter, far more rarefied corner of Casio's catalog. G-Shock excels in the affordable watch category so much that most forget the Japanese brand also, from time to time, makes luxury watches too. It all started back in 1996, when G-Shock aspired to transpose its shock-resistant technology to a full-metal timepiece — a task that seemed impossible, if not contradictory. Brand founder Kikuo Ibe and his small team worked diligently, ultimately solving the problem by separating exterior components like the bezel from the case and incorporating cushioning between them. The MR-G line was born.
Since 1996, Casio has been running MR-G as its made-in-Japan flagship line, built to prove the toughest name in watchmaking can also hang in actual luxury territory. It is a line that has never chased volume. Every piece in it is machined, assembled, and finished in Japan with considerably more deliberation than what rolls off the standard G-Shock line. Casio has spent three decades proving its toughest engineering can thrive in high-end luxury watchmaking through the MR-G line. And now, on the occasion of its 30th anniversary, the brand is pulling out every stop it has.
Why the CasiOak Silhouette Was the Right Canvas
To understand why Casio chose the B2100 body for this celebration, you have to understand what the CasiOak became in a very short period of time. The G-Shock GA-2100 was launched in 2019 and quickly reached classic status in just a few years, achieving a place alongside such long-running models as the DW-5600 from the '80s, the DW-6900 from the '90s, and the GA-110 from the 2010s. That's a rare trajectory — going from new release to instant icon within a single product cycle.
The B2100 series, affectionately known as the "CasiOak" for its resemblance to the Royal Oak, earned its moniker from a case shape and dial layout that loosely resembled Audemars Piguet's discreetly decadent watch. The connection runs deeper than casual imitation, though. In 1972, two years before Casio threw its hat into the timepiece ring, venerable Swiss manufacture Audemars Piguet took a bold gamble on a model called the Royal Oak, its own first attempt at a fusion of sport watch and dress watch elements. The Royal Oak's octagonal bezel, integrated bracelet, and tappiserie dial became defining symbols of integrated sports-luxury design. When Casio's engineers landed on a similar vocabulary for the 2100, the internet did what the internet does — and a nickname was born.
The GA-2100 was an absolute sensation when it launched and resulted in a worldwide shortage of the GA-2100-1A1 — surprising to many fans as well as to Casio, since there was not a lot of buzz about it in advance. What made the watch particularly compelling wasn't just the shape. Use of the latest toughness-driven construction with carbon fiber-reinforced resin made it possible to slim the case to the utmost limit, giving the CasiOak a profile that was radically thinner than any performance G-Shock before it. At around 11.8mm thick, it wore like something much more refined than the armor-plated tool watches the brand had been known for — while hiding every bit of G-Shock's mechanical toughness inside.
Meet the MRG-B2100HR: Specs, Materials, and the Art of Iridescence
A Case Built From Elite Alloys
Limited to just 800 pieces, the MRG-B2100HR takes the fully analog CasiOak and turns it into a luxury stunner. The exterior combines grade 5 titanium for the case and Cobarion for the bezel, the latter of which is a super-hard cobalt-chrome-molybdenum alloy known for its platinum-like gleam. This isn't material selection for the sake of marketing copy. Cobarion is genuinely extraordinary stuff — the kind of alloy that aerospace and high-end medical applications reach for when performance demands exceed what conventional metals can offer. On a watch bezel, it provides a surface hardness that resists scratching in ways that stainless steel simply cannot, and the alloy's natural color sits close enough to platinum that it reads as precious even before any surface treatment is applied.
The bracelet, made of DAT55G titanium alloy, gets the treatment as well. DAT55G is Casio's go-to titanium for high-end MR-G pieces — a proprietary alloy that is reported to be significantly harder than conventional titanium, making it substantially more resistant to everyday wear and abrasion without adding meaningful weight. On the wrist, the combination of these materials means the watch is simultaneously lighter than a comparable stainless steel piece and far more wear-resistant.
The watch measures 49.5mm long, 44.4mm wide, and 13.6mm thick, with a listed weight of 122 grams — so while this is still very much a G-Shock in terms of presence, Casio is clearly treating it as something much more special than another color variation. The proportions place it in serious sport-watch territory without crossing into the kind of wrist-dominating bulk that makes many G-Shocks impractical in professional settings.
The Iridescent Bezel: Structural Color at the Micron Level
The bezel treatment on the MRG-B2100HR is where things get genuinely jaw-dropping — and where Casio's engineers had to invent techniques rather than adapt existing ones. An iridescent texturing is applied to the Cobarion bezel for a stunning effect. Rakusho foil-pressed the bezel to achieve a brilliant iridescent effect using ultra-short-pulse laser structural-color texturing.
The opal-like multicolor finish of the bezel and band, inspired by Rakusho's original artwork, is made with structural color technology by using precision laser processing with an ultrashort-pulse laser. Casio defines structural color technology as "the phenomenon in which iridescent colors appear on butterfly wings, minerals, and other objects." Precision laser processing at the micron level produces beautiful colors that change depending on the viewing angle. This is not dye or paint or PVD coating — there is no added pigment involved. The color is entirely the result of surface geometry interfering with light at the nanoscale, the same physical principle that gives a peacock feather its impossible shimmer or an opal its internal fire.
Casio describes the MRG-B2100HR as wearable art and says the shifting colors across the bezel and bracelet are intended to reproduce the constantly changing character of Rakusho's metal-leaf work — and in Casio's studio photography at least, the color looks deep, with different surfaces seeming to separate from one another, and the whole thing has much more visual dimension than expected. Whether those shifting tones translate equally well under office fluorescents or the cloudy skies of a Tuesday afternoon is the question every serious buyer will want answered in person.
Hiroto Rakusho: The Kyoto Master Behind the Dial
The most remarkable element of the MRG-B2100HR isn't a material specification — it's a name. The headliner is Hiroto Rakusho, a Nishijin-born metal leaf artist certified by Japan's government as a Master of Traditional Crafts. Rakusho created an original artwork titled Haruka — meaning eternity — for the anniversary, then applied that newly built world into a stunning watch.
Rakusho is a metal leaf artist from Nishijin in Kyoto. He learned the craft from his father, Jisaku Nishiyama, and set up his own brand in 2002. Nishijin is the historic weaving and craft district of Kyoto, a neighborhood whose artisans have supplied Japan's courts, temples, and shrines for centuries. The metal leaf tradition Rakusho works in is among the oldest decorative arts in Japan, rooted in practices that long predate any mechanical watchmaking tradition in either East or West.
The MRG-B2100HR-1A has a dimensional latticework dial inspired by kigumi, a traditional Japanese method of joining wooden components without nails or other metal fittings. Kigumi woodworking is itself a profound craft — the joinery technique used in Japan's great temples and traditional architecture for more than a thousand years, relying entirely on interlocking geometry and exquisite tolerance rather than any fastener. Translating that visual vocabulary to a watch dial isn't a surface-level reference. It's a structural idea applied in miniature: interlocking raised elements that create depth and shadow across a surface no larger than a thumbnail.
Each limited-edition timepiece is adorned with platinum leaf personally applied by Rakusho himself. Powdered platinum leaf creates a subtle shimmer and gradations of light and dark that impart a sense of depth and give each timepiece its own distinct character. Rakusho personally applies powdered platinum leaf by hand onto the raised lattice components of every single watch dial. Because the foil-stamping and finishing processes rely on human hands rather than automated machinery, variations in shimmer and shading mean that no two watches in the 800-piece run will look entirely identical. That last point is worth sitting with: in a world where luxury goods increasingly chase perfection through robotic precision, Casio and Rakusho are leaning into the irreducible variation of the human hand as a selling point. Every single one of the 800 pieces is, technically, a unique object.
The Haruka Concept: Art, Philosophy, and Watchmaking in One Package
Commemorating the 30th anniversary of G-Shock's top-end MR-G line, the theme of the watches is "strength and beauty that transcends time" through the concept of Haruka — eternal time and boundless expanse. It's a theme that resonates on multiple levels when you consider what G-Shock and MR-G have actually accomplished over three decades: building watches so robust that they outlast the conditions they were designed for, and doing so while managing to also be genuinely beautiful.
To commemorate the 30 years since the debut of MR-G in 1996, Casio drew from metal leaf, embodying tradition and innovation. The design expresses a strength that transcends time through the theme of haruka. Metal leaf artist Hiroto Rakusho created an original artwork, which together with the timepiece design brings the world of haruka to life. The concept is not applied loosely. Platinum — the material Rakusho used for the primary model — is one of the densest, most stable, and most corrosion-resistant elements on Earth. It doesn't tarnish. It doesn't oxidize. It doesn't react. As a symbol of something meant to endure, there's a quiet logic to choosing it over gold.
Two Versions: Platinum and Gold, 800 and 150
While the MRG-B2100HR-1A — the platinum leaf version — is the watch generating most of the coverage, Casio is releasing a sibling alongside it. A gold leaf sibling, the MRG-B2100HS-9A, is coming in an even tighter run of 150 pieces. The MRG-B2100HR is limited to 800 pieces worldwide and the MRG-B2100HS to 150, and both are serial numbered on the case back. The gold one also ships in a box gilded with gold leaf and signed by Rakusho.
The MRG-B2100HR-1A features platinum leaf foil on the dial, and the gold-accented MRG-B2100HS-9A uses gold leaf foil. Both watches come with a specially commissioned box, and the MRG-B2100HS-9A box is individually gilded with gold leaf and signed by Rakusho. For serious collectors, a box that is itself a hand-finished artifact is more than a nice touch — it establishes the watch as an object that inhabits the world of fine art rather than consumer electronics, regardless of where it originated.
Price, Release Date, and the Question of Value
The MRG-B2100HR-1A arrives in November 2026 priced at ¥1,100,000 (~$7,000), with US pricing still to be announced. That puts it in a category where it will inevitably be compared against entry-level Swiss luxury — the kind of territory occupied by base Rolex Oyster Perpetuals, mid-tier Omega Seamasters, and the lower rungs of IWC and Panerai. Against that backdrop, the conversation gets interesting fast.
What the MRG-B2100HR offers that none of those competitors can is the combination of genuine artisanal craft — a named artist, a traditional technique, provable hand-finishing — with G-Shock's unmatched functional pedigree. The watch's practical advantages are focused: titanium construction, specialty alloys, and coatings chosen to help preserve its appearance. The rest of the premium buys craftsmanship and exclusivity, not a dramatic increase in everyday function. That's an honest framing. The MRG-B2100HR has solar charging, Bluetooth connectivity, and the full suite of G-Shock timekeeping functions — but those features are available in far less expensive watches. The $7,000 is a payment for the Cobarion bezel, the DAT55G bracelet, the kigumi-inspired latticework, and above all, for Hiroto Rakusho's hands on every dial.
For the collector who already owns a standard CasiOak and wants to understand where the design can go when cost is no object, this watch provides a definitive answer. The MRG-B2100HR-1A makes the most sense for someone who already loves the 2100 design and wants an unusually elaborate version of it. Its hand-finished dial, complex metalwork, and limited run are the appeal.
Where This Fits in G-Shock's Ongoing Evolution
The MRG-B2100HR doesn't exist in isolation. G-Shock has spent the last few years deliberately expanding the CasiOak's footprint upmarket. The Full Metal GMC-B2100ZE retains the collection's approachable price at $930, while closing the gap slightly in quiet luxury appearance. The G-Shock GMC-B2100ZE has a black ion-coated steel case and bracelet. It retains the collection's approachable price at $930 while closing the gap slightly in quiet luxury appearance, with its matte black ion-coated stainless steel case and bracelet emphasizing gilded central hands, hour markers, day track, and a single bracelet link.
Below that sits the full-metal GMC-B2100D-1A, a meaningful evolution of the 2100-series CasiOak line — itself a modern reimagining of the original 1983 DW-5000C G-Shock, with an octagonal bezel that has since attracted a cult following for its resemblance to a certain Swiss integrated sports watch. The GMC-B2100D-1A — the brand's first full-metal, fully analog chronograph and one of the most significant CasiOak releases of 2024. At the very top now sits the MRG-B2100HR, priced at nearly eight times what a flagship GMC costs. That's a remarkable range for a single design language to span — from four figures to just under seven thousand dollars — and it speaks to how deeply the CasiOak form has embedded itself in watch culture.
G-Shock used recent years to prove, once again, that no one does "indestructible but fun" quite like Casio's cult-favorite sub-brand. The years' hits stretched from full-metal 5000-series squares and sharp 5600 collabs to stealthy new analog-digital hybrids that pushed the CasiOak family in fresh directions. The MRG-B2100HR is the logical apex of that trajectory — not a collab or a limited colorway, but a genuine rethinking of what a G-Shock can be when the brief is to make something extraordinary rather than accessible.
The Broader Significance: When Craft Meets Toughness
There is a strain of thought in serious watch collecting that the only honorable luxury timepiece is one built on a mechanical movement — ideally in-house, ideally hand-wound, ideally Swiss. By that calculus, no quartz watch, regardless of its material pedigree or artisanal finishing, can belong in a serious collection. The MRG-B2100HR challenges that orthodoxy directly, and it does so from an unexpected direction.
Hiroto Rakusho's involvement is not a celebrity endorsement or a branding exercise. Rakusho is a metal leaf artist certified by Japan's government as a Master of Traditional Crafts. That designation carries weight in Japan comparable to what a Living National Treasure certification means in the arts — it is the government's formal recognition that a practitioner has mastered a craft deemed worthy of preservation. Having such a practitioner finish 800 watch dials by hand is not a marketing story. It is a genuine transfer of a rare skill onto a functional object, and it places the MRG-B2100HR in the same conversation as grand-feu enamel dials, hand-engraved movements, and other artisanal techniques that define haute horlogerie at its most serious.
The design brings together traditional techniques and cutting-edge technology to highlight the beauty of metal leaf. That combination — ancient craft, aerospace-grade alloys, micron-scale laser processing — is precisely the kind of synthesis that defines the most interesting objects being made anywhere in the world right now, and it is not a synthesis most watch brands would have the institutional imagination to attempt. Casio, with its dual identity as electronics giant and craft custodian, may be uniquely positioned to pull it off.
Final Verdict: Built for the Collector Who Knows What G-Shock Really Is
The MRG-B2100HR-1A will not be for everyone, and Casio isn't pretending otherwise. This is the 30th-anniversary MR-G — Casio is making just 800 of them worldwide, and the Japanese price is ¥1,100,000, which works out to roughly $7,000 at current exchange rates. With US pricing yet to be confirmed and stock that will move fast among MR-G loyalists and high-end G-Shock collectors, anyone serious about acquiring one will want to be ready when November arrives.
What Casio has built here is a watch that defies easy categorization in the best possible way. It is simultaneously a G-Shock and a work of applied art. It is waterproof and solar-powered and Bluetooth-connected, and it is also hand-finished by a Kyoto craftsman whose skills are recognized by the Japanese government as a national cultural asset. Its bezel shifts color like a mineral specimen under different light. No two of its 800 dials are the same. And it all rides on a silhouette — the CasiOak — that managed to become one of the most culturally resonant watch designs of the last decade for under a hundred dollars.
That is not a contradiction. That is a brand at the full expression of what it is capable of. The MRG-B2100HR is one of the most stunning watches G-Shock has ever made, and it earns that distinction not through gimmickry or mere scarcity, but through the rare combination of material ambition, artisanal depth, and a design foundation strong enough to carry the weight of both.
