G-SHOCK’s MR-G Shougeki-Maru is
inspired by samurai gear

12 December 2020


SINGAPORE — Casio Computer Co., Ltd. has released its latest addition to the MR-G Series, the flagship line of the G-SHOCK brand of shock-resistant watches. The MRG-B2000SH Shougeki-Maru 衝擊丸 takes its inspiration from the traditional kabuto (helmet) worn by Japanese samurai. A limited edition of just 400 of these watches has been released worldwide.

The new MRG-B2000SH is inspired by Shougeki-Maru, an original kabuto piece that was commissioned for MR-G. Kabuto were worn by Japanese samurai when heading into battle and are known for their distinct aesthetic and symbolism of the strong convictions of the samurai. These qualities resonate with the MR-G pursuit of ultimate toughness and aesthetics.

Right: Metal artisan Masanao Kikuchi

Befitting the MR-G Series and its continued pursuit of excellence, each bezel is individually hand carved by Masao Kobayashi (top), a metalsmith highly skilled in the technique of chasing, with the image of a dragon climbing to the heavens.


The surface of the bezel and band simulates the tetsu sabiji (rusted steel) finishing technique used on the Shougeki-Maru kabuto helmet. The aged feel was reproduced by metal artisan Masanao Kikuchi, who used special dyes. Furthermore, the bezel is finished with layers of brown and blue ion plating (IP) to create the rugged look of rusted steel, while the band is finished with a navy blue ito odoshi (overlaying plates of armour bound together with a navy blue string) used in the Shougeki-Maru kabuto. This gives a unique textured finish that enhances the deep colours of the rusted steel look.


The rugged textures and unique colours create a deeply inspired design that evokes the aged beauty of the kabuto helmet.

In terms of features, the MRG-B2000SH pairs with a smartphone using Bluetooth® and receives radio wave time-calibration signals, automatically correcting the time upon arriving in a different time zone without having to operate the buttons. The MRG-B2000SH is a truly special watch that delivers both advanced technology and master craftsmanship.
