G-Shock MRG Series

Robust and valiant 




Robust and valiant 
 the dignified spirit of a warrior, 
expressed with a traditional hue

This new watch immediately made a place for itself in our flagship MR-G line of G-SHOCK watches, which we continue to advance in pursuit of the ultimate in strength and beauty.

The spirit of a warrior expressed with kachi-iro

The traditional Japanese hue of kachi-iro is a deep shade of navy blue seen in indigo dyeing. A favourite of warriors, who also called it katsu iro (“the colour of winning”), it was used to adorn helmets and armour for auspicious luck. Used as an accent colour in the watch design, it delivers a dignified appearance infused with the spirit of a warrior.

A traditional Japanese hue called kachi-iro, literally “victory colour,” accents the watch’s design. A shade of deep navy blue meant to ensure victory, the colour adorned the helmets and armour of samurai warriors who achieved distinction through triumph. The spirit of these warriors and their approach to life shines through in every aspect of the design. From materials and construction to functionality — all are informed by uncompromising particularity. This new MR-G stands as heir to the time-honoured Japanese traditions of strength and aesthetic beauty.

Face design projecting strength and brilliance

Uroko-mon, a traditional Japanese triangular scale pattern, is applied to the base surface, while cuts evoking the look of folding fans/screens adorn the perimeter. For the index, Yamagata Casio’s nano-treatment technology is used to apply a grind-mark finish to sharp edges and curved surfaces to evoke the gentle curvature of a sword blade. Kachi-iro is applied to the inside of the bezel as well as the inset dials and logos for a robust look.

Special model with recrystallised titanium bezel

Recrystallised titanium is used to make the bezel. Applying a heat treatment brings out a distinctive crystallised pattern in the material, evoking the crystalline nie patterns that appear on Japanese swords. A Dura Soft Fluoro-Rubber band offers a soft, comfortable feel on the wrist as well as durability. It features the geometric bishamon kikko tortoiseshell pattern, a symbol of strength.

* Above description applies to the MRG-B2000R.

A double hardening process to preserve the beauty of titanium

A deep-hardening process gives the surface a hardness 4 to 5 times that of pure titanium. A diamond-like carbon (DLC) coating is also used to apply a carbon film with hardness approaching that of a diamond to the surface. This is total hardness with great beauty.

Clad Guard structure for reliable shock resistance and operability

Integration of the crown/buttons and guard parts offers improved shock resistance. αGEL* inserted into the crown helps to absorb shocks.

Metal Bezel Carved with Ascending Dragon

The Shougeki-Maru’s bezel evokes a helmet’s crest. Highly skilled in the technique of chasing, metalsmith Masao Kobayashi has carved the image of a mythical dragon on each. With his hand carving, no two watches are exactly alike.

Masao Kobayashi

Third-generation metal craftsman working in Shiga Prefecture’s city of Otsu. Active as a metalsmith using the chasing technique as well, with experience studying carving in Kyoto. Works with a wide range of decorative metal crafts, including crafting shrine and temple fixtures, restoring historic cultural assets, crafting tea ceremony implements and engaging in artistic craftwork. One of Japan’s premier artisanal metalworkers.

Forged Bezel and Band with
Rusted Steel Texture

The Shougeki-Maru’s bezel and band impart its textural feel to it. Forged using a sand die by Masanao Kikuchi, they reproduce the rugged look of rusted steel. A highly-skilled technique using a sand die, with brushes and misting tools, is required to bring out the unique textured finish in the metal’s surface.

Masanao Kikuchi

15th-generation craftsman for Kikuchi Hojudo, founded in 1604 as a dedicated iron caster for the lord of Yamagata Castle. Received instruction from his uncle, a Living National Treasure, from a young age and apprenticed under his father, the 14th-generation Masanao Kikuchi. His works, creatively innovative even as they preserve traditional techniques, are highly esteemed throughout Japan and the world.


Blue-Aged IP

Titanium treated with a deep-hardening process is finished with layers of both brown and blue IP. Removal of the blue IP from the convex surface produces the watch’s unique look, with its rusted steel texture and prominent ascending-dragon image. The coloration of the watch also creates the look of the navy blue ”KON ITO ODOSHI” * used in Japanese helmets and armor.

Recrystallized Titanium Case

A heat treatment applied to the titanium creates a unique crystallized pattern effect. The combination of deep-hardening treatment and brown AIP®* offers enhanced resistance to abrasion.
