G-Shock MR-G B2100 combines the best of two worlds

What do you get when you cross the popular G-Shock 2100 series with the handmade MR-G premium line? The MRG-B2100B.

The comfortable dimensions and fit of the B2100 have been retained and equipped with a lightweight metal housing made from the latest materials. As usual with the watches in the MR-G line, the watch is hand finished by Japanese masters. This time inspired by 'Kigumi'; a traditional Japanese decorative woodworking method, but made from extra hard, lightweight titanium.

Meet the fusion of the B21000 series and MR-G

In 2022, the MRG-B5000 was released, an upgraded reproduction of the very first G-Shock model (DW-5000C). The MR-G range has since been expanded, always with reinterpretations of classic G-Shocks, such as the MRG-BF1000R-1ADR Frogman. Unlike previous MR-G releases, with the MRG-B2100B the design of the basic model ( GA-2100) was not adopted 1 on 1, but rearranged.

Stripped-down design

Combining the distinct B2100 design with multiple (digital) windows and three hands and the stylish minimalism of MR-G was no easy task. In addition, the use of a dial with high light transmittance was crucial for the generation of solar energy. Therefore, the MRG-B2100B has a simplified layout, with a sub-dial placed between the 7 and 8 o'clock positions, combined with a three-dimensional dial.

At the same time, the watch has a sturdy but high-quality appearance that matches MR-G. The case size of 44.4 mm wide and 13.6 mm thick may seem large, but combined with the lightness of the titanium case and bracelet, it feels wonderful to wear despite its heavy appearance.

27-part bezel and high-quality polishing

G-Shock has focused on making the sleek, simple shape of the 2100 as beautiful and strong as possible. The bezel is formed from 27 separate components instead of one piece. Each part was 'Sallaz' polished prior to assembly to give the watch a beautiful finish, even the recessed parts.

The originally Swiss Sallaz polishing technique for which G-Shock has developed its own machines, makes it possible to polish the watch's distinctive case to a smooth, distortion-free surface with clearly defined edges.

Kigumi latticework dial

Kigumi is a traditional Japanese construction method and woodworking technique that was used for wooden joinery. Geometric shapes are created with a high degree of precision without the use of nails or other metal fittings. The technique has been used since the Heian period (794–1185) to build wooden structures, including shrines and temples.

The idea of ​​using woodworking in the design of the MR-G has actually been around since the time of the first MRG-B5000. When this model was developed, the structure of the case lid parts, which were divided into smaller parts, was already described as 'Kigumi'.

However, the complicated three-dimensional structure of the Kigumi lattice as a dial turned out to be more difficult to produce than it seems. Before the hole sizes were determined, many tests were conducted using the nanoprocessing and precision casting technologies of Casio's Yamagata factory. Ultimately, a balance was achieved between aesthetics and feasibility. The lattice-like structure of the dial is not only suitable for ensuring the amount of light required for solar energy generation through the holes, but at the same time improves the texture of the dial.

Thin(ner) case

G-Shock has also managed to make this watch approximately 3mm thinner than the MRG-B2000 series with a similar movement, to match the sleek shape unique to the GA-2100. At the same time, this also led to a reduction in the weight of the entire watch.

Made from extra hard, lightweight materials

A special Ti64 titanium alloy is used for the case, back and buttons of the watch and the ergonomically shaped bracelet is also made of titanium, but a completely different alloy known as DAT55G, a proprietary material developed by Japan's Daido Steel Company that according to G-Shock is three times harder than the typical titanium alloy used in watchmaking.

The bezel is made of yet another type of titanium: cobarion, the material also used in the MRG-B5000. Developed in Japan, this alloy is approximately four times harder than pure titanium and has excellent scratch resistance. When polished, it has a luster similar to that of precious metal.
