On the WatchTested website, we have often highlighted the incredible variety of Casio G-Shock models.
In over 40 years since its inception, this ultra-durable sub-brand has occupied almost every possible niche - from budget models priced around $100 to genuine luxury items costing several thousand dollars, offering a wide range of colors, materials, shapes, sizes, and specializations. There is practically a G-Shock for everyone - almost everyone.

If there is one aspect that G-Shock has almost never achieved, it is classic sophistication. The general consensus is that such a sense of elegance is almost contrary to the spirit of the G-Shock brand, yet one of the latest models in the MR-G line may change this perception. The Casio G-Shock MR-G MRGB2100D-2A "Hanada-Iro" - while a new color version of an existing model - with its more traditional blue dial and metallic execution, represents the most refined embodiment of the "Casioak," capable of competing with familiar Swiss integrated sports watches in terms of finishing, impact, and possibly even elegance.
Case and Design: A Blend of Tradition and Innovation
The case of the Casio G-Shock MR-G MRGB2100D-2A "Hanada-Iro" measures 44.4 mm in width and 13.6 mm in thickness, repeating the shape of previous MR-G models, but the use of the proprietary Cobarion alloy with titanium inner elements fundamentally changes the character of the watch compared to its black DLC-coated "siblings."

In black, this luxury version of "Casioak" is perceived at first glance as a classic G-Shock, and only upon closer inspection do the multi-layered design, high-quality finishing, and extremely sharp surfaces become apparent. In turn, the "Hanada-Iro" on the wrist can be characterized in one word - "sharp." Every angle, edge, and transition between finishes is executed with the utmost precision and care, emphasizing the geometric shape of the case. The high-quality finishing gives the familiar G-Shock shape a new sense of elegance and sparkle.

Deserves Special Attention:
- Deep black polishing on the bezel edge and internal side grooves of the case
- Transitions between vertical and diagonal brushing that highlight the faceted surfaces of the "hooded" lugs
As befits a G-Shock, the "Hanada-Iro" cannot be called a compact watch, yet on the wrist, it appears significantly smaller than the numbers suggest. In practice, the fit is comparable to 42mm integrated sports watches - large enough yet not exceeding modern standards, despite some case thickness, offset by well-balanced side proportions. The case is completed by a titanium case back with an engraved MR-G logo and an impressive Clous de Paris pattern. Despite the elegant presentation, this remains a G-Shock with an impressive 200-meter water resistance and nearly invulnerable shock protection.

Dial: Minimalism and Inspiration from Japanese Traditions
The second component of the MR-G MRGB2100D-2A's elegant image is the dial. The typical array of additional indicators and complications found on analog G-Shocks is almost absent here, leaving just one sub-dial with a day-of-the-week indicator and functions at the 8 o'clock position. The main focus is on the surface texture and high level of execution. The faceted, mesh main dial is a true work of art, inspired by the traditional Japanese technique of kigumi box making. Depending on the viewing angle, the color changes from almost black to a rich oceanic blue. This color scheme brings the "Hanada-Iro" closer to classic premium integrated sports watches while retaining the distinctive G-Shock character.
Features of Hands and Indices:
- Wide, ultra-polished facets - a clear Japanese design accent
- Partially skeletonized sword-shaped hands give a modern, aggressive, and sporty appearance, different from most similar models

Casio has equipped the MR-G MRGB2100D-2A with its own solar-powered quartz movement, Module 5718. For a G-Shock, the functionality of this module is quite modest: it only includes a self-adjusting perpetual calendar accurate until 2100 and LED backlighting for the dial. For everyday use, this is more than sufficient, and it is practically impossible for mechanical competitors to replicate such capabilities.
Key Features of Module 5718:
| Parameter | Value |
|---|---|
| Power Reserve | 18 months |
| Accuracy | ±15 seconds per month |
| Automatic Time Adjustment | Radio control 6 times a day |
Bracelet: Balance of Tradition and Luxury
The bracelet of the Casio G-Shock MR-G MRGB2100D-2A "Hanada-Iro" combines recognizable G-Shock design elements with a sense of elegance through high-quality finishing. Formally, this is not an integrated bracelet, yet the smooth taper and repeating recesses fit seamlessly into the overall watch design.
Bracelet Features:
- Each link consists of at least three components
- Polished sloping walls of the recesses resemble stone settings in mechanisms
- The bottom of each recess is filled with a radially brushed disc
- Three types of finishes on one link: linear brushing, polished bevels, radial brushing
- Black mirror finish and a clasp with a folding buckle give the bracelet a luxurious yet recognizable G-Shock look
Conclusion: A New Era of Refinement in the G-Shock World
Despite the vast variety of Casio G-Shock models throughout history, describing these watches as refined or genuinely elegant always seemed inappropriate. However, if there is a model capable of changing this opinion, it is the Casio G-Shock MR-G MRGB2100D-2A "Hanada-Iro." The watch is already available from select official dealers. The recommended retail price at the time of publication is $4,700 USD.
