In the world of fine craftsmanship, there are few things as revered as the Japanese katana—a symbol of precision, strength, and tradition. This philosophy of mastery and resilience is at the core of the latest Casio G-SHOCK MR-Grelease. Introducing the MRG-B2000JS, a striking fusion of modern horology and ancient sword-making artistry, inspired by the Juryoku-Maru: San, a one-of-a-kind katana commissioned by Casio.
This extraordinary timepiece, available in a strictly limited run of just 800 pieces worldwide, embodies the soul of Japanese craftsmanship, blending cutting-edge materials, time-honoured techniques, and a deep appreciation for heritage.
THE SPIRIT OF THE JURYOKU-MARU: SAN
At the heart of the MRG-B2000JS lies its inspiration—the Juryoku-Maru: San, a katana that seamlessly marries power and elegance, much like the MR-G line itself.
Forged by the renowned master swordsmith Kamiyama Teruhira, the blade represents centuries of samurai tradition, while the exquisite aogai blue shell lacquer scabbard, crafted by artisan Nomura Mamoru, adds a modern yet deeply rooted aesthetic. Casio’s vision for this ultra-limited timepiece was to capture the essence of the katana’s strength, balance, and intricate beauty—a challenge that required exceptional innovation and artistry.
A DESIGN INSPIRED BY MASTER SWORDSMITHING
The MRG-B2000JS is more than a watch; it is a wearable work of art, infused with the spirit of the katana at every level of its design.
The recrystallized hybrid titanium bezel is a true nod to traditional sword-making. Crafted from Ti64 and pure titanium, it undergoes an intense high-temperature, high-pressure compression process, followed by precision cutting, polishing, and recrystallization. The result? A surface texture that mirrors the stunning blade patterns of the Juryoku-Maru: San, offering a distinct and uniquely Japanese aesthetic.
The bracelet of the MRG-B2000JS carries the same artistic DNA as the katana’s aogai lacquered scabbard. Crafted from DAT55G titanium alloy—a material three times harder than pure titanium—it is adorned with delicate micro-etching, reflecting light in a way that creates shimmering, ever-changing hues, just like the lacquered blue shell of its sword counterpart.
Adding an even deeper layer of significance, each individual timepiece is engraved by Kamiyama himself, marking it with the kanji character 燦 (San), meaning radiance. This hand-engraved detail ensures that no two watches are exactly alike—each one carries its own distinct personality, much like the blade of a master-forged katana.
LIMITED TO 800 PIECES: A COLLECTOR’S DREAM
With only 800 pieces available worldwide, the MRG-B2000JS is more than just a statement of refined taste—it is a collector’s treasure. Designed for watch aficionados, samurai culture enthusiasts, and G-SHOCK devotees alike, this release cements Casio’s position at the intersection of heritage and innovation. The MRG-B2000JS isn’t just about keeping time—it’s about honouring it.
