Casio is adding another option to its high-end G-Shock lineup with the MRG-B2100D-2A. It’s a luxury timepiece that builds on the familiar 2100-series design.
The watch draws inspiration from the Five-Storied Pagoda on Mt. Haguro in Japan’s Yamagata Prefecture. Interestingly, the site is also close to Casio’s “mother factory,” where the MR-G series is made.

The pagoda itself dates back to the 10th century and was designated a National Treasure in the 1960s. Casio says the dial’s deep indigo tone reflects the image of the pagoda surrounded by morning mist at dawn. Traditionally known as “hanada-iro,” this shade of blue subtly shifts depending on light and viewing angle.
Like other MR-G models based on the 2100 design, the MRG-B2100D-2A keeps the distinctive octagonal shape and a dial pattern inspired by kigumi, a traditional Japanese wood-joining technique. The result is a layered, three-dimensional texture rather than a flat surface.

In terms of materials, this is very much a peak MR-G model. The case and bezel are made of Ti64 titanium alloy, while the top bezel is made from Cobarion, which is known for its hardness and shine.
Meanwhile, the bracelet is crafted from DAT55G, and the entire watch is finished with a titanium carbide coating to improve scratch resistance. The case measures 49.5 x 44.4 x 13.6mm and weighs 122 grams.



Functionally, it includes what you would expect from Casio at this level. The watch has Tough Solar charging, Multi-Band 6 radio timekeeping, Bluetooth smartphone connectivity, a sapphire crystal with anti-reflective coating, a full auto calendar, date and day indicators, and an LED light.
In Japan, the MRG-B2100D-2AJR is listed as “coming soon” for January. It is priced at 572,000 yen, which translates to some $3,632. That puts it in line with the black-dial version already on sale.
