G-SHOCK celebrates its Japanese heritage to perfectionwith the new MRG-B2100R
Traditional Japanese aesthetics meet the ultimate strength and beauty of the MR-G

Norderstedt, January 21, 2025 – G-SHOCK today presents the MRG-B2100R-2ADR, the latest addition to the MR-G collection, the Japanese brand's Premium Line. The new MRG-B2100R combines traditional Japanese aesthetics and Zen sensibilities with the ultimate strength and beauty of G-SHOCK in its design.
The MRG-B2100R's elegant dial features a clear geometric pattern inspired by the Japanese Kigumi. Kigumi is a traditional Japanese construction and woodworking technique that involves making wood joints without additional materials such as nails or glue. The deep blue Ao Zumi color accents used in the design symbolize serenity and depth and are reminiscent of the blue-tinged sumi ink used in traditional Japanese ink painting and calligraphy.
The dial of the MRG-B2100R has a wavy shape with elegantly placed cut-outs, which together create a three-dimensional, geometric Kumiko* pattern. The pattern is not only a sophisticated design feature, but also allows enough light to generate solar power through the cut-outs. The dial was completely vapor-coated with the deep blue Ao-Zumi color. Further color accents can be found on parts of the bezel, which are finished using ion plating, which contrasts strongly with the deep black DLC coating of the case.
*The traditional Kumiko craft is a technique of delicate and high-precision wood connections and, among other things. an important element of Japanese interior design culture. The Kumiko artisans draw from the extensive treasure trove of forms of Japanese ornamentation and create geographical grid structures from delicate wooden strips
The MR-G's distinctive octagonal 2100 case consists of a complex bezel made up of a total of 27 individual parts, which are precisely polished down to the most difficult recesses to achieve a flawless metal surface. The external components are individually polished by master craftsmen and then assembled in a process as demanding as Kigumi woodworking itself. The top bezel is made of COBARIONTM**, an alloy developed in Japan with a hardness approximately four times that of pure titanium, and the bracelet is made of DAT55G, a titanium alloy whose hardness is approximately three times that of pure titanium.
**COBARION® is a registered trademark of Iwate Industry Promotion Center and is exclusively used by Eiwa Co., Ltd. manufactured.
The comfortable Dura-Soft bracelet has high resistance to discoloration, stains and wear while still fitting around the wrist. Titanium components increase the strength of the connection of the bracelet to the case. The high-quality titanium safety clasp completes the stylish design.
The new MR-G is also functionally impressive: When paired with a smartphone via Bluetooth®, it is possible to connect to time servers on the Internet and update summer time and time zones. The fully automated clock shows the exact time anywhere in the world and is therefore completely reliable.
This timepiece combines the refined strength and beauty of a G-SHOCK with Japanese craftsmanship.

About G-SHOCK
ABOUT G-SHOCK G-SHOCK was born from the idea and desire to create an indestructible watch. CASIO engineers followed the “Triple 10” concept, which required the watch to survive a drop from a height of 10 meters, withstand 10 bar of water pressure and last for 10 years on just a single battery. Since its launch in 1983, G-SHOCK has stuck to this concept and continually perfected the G-SHOCK models through development. The cult brand has made a name for itself worldwide in the areas of fashion, sports and music. As a testament to this success, G-SHOCK celebrated its 40th anniversary in 2023.
