For those who truly appreciate the cutting edge of master craftsmanship — a limited edition 40th anniversary G-SHOCK collaboration watch featuring the stunning techniques of master swordsmith Sadanobu Gassan.

Evoking the philosophy of the Japanese sword, the titanium band is crafted by Gassan to resemble a tang. This hidden, but pivotal part of the sword is traditionally marked with a yasuri-me pattern to keep the blade firmly in the handle. Gassan hand-carves the watch band with these marks and with 鍛 and 錬 inscriptions as a symbol of his family’s devotion to swordsmithing. This dedication to detail and excellence imbues each timepiece with a unique presence all its own.

Casio introduces its all-new hybrid titanium bezel that evokes the look of the Gassan family’s signature ayasugi-hada patterns. This newly developed titanium is crafted with recrystallized layers of pure and Ti64 titanium, a process overseen by Gassan himself to capture the true beauty of a sword blade’s temper patterns.

The blue-gray bezel, band and case back, finished in the most recent addition to Casio color ion plating technology, express the blue-tinged ferrous coloration

that is the mark of a finely crafted sword. Recrystallized pure titanium for the case features a distinctive crystallized pattern treated with a deep-layer hardening process and a titanium carbide finish for even greater strength and abrasion resistance. An engraved metal plate commemorating the G-SHOCK 40th anniversary at the 10 o’clock position adds a final touch of edgy styling.

This truly special MR-G celebrates both the traditional artisanal techniques and cutting-edge technologies of Japan — all in a singular sword-inspired timepiece.
