Tapping into the dawn-blue silence of Tohoku’s oldest pagoda, the G-SHOCK MRG-B2100D-2A captures the timeless spirit of the five-storied mountain treasure nestled in the forests of Yamagata. Shrouded in the imagery of morning mist, the dial is finished in traditional Japanese hanada-iro blue, a clear hue that shifts in tone depending on the light and viewing angle. The face itself is inspired by kigumi, a traditional interlocking woodwork technique, creating a geometric latticework that evokes both structural strength and a sense of tranquil elegance.

The watch's construction is a masterclass in metal craftsmanship, featuring an intricate 44.4mm case and octagonal bezel comprised of 27 individual components. Every part is meticulously hand-polished to a distortion-free mirror finish before being treated with a titanium carbide (TiC) coating for superior scratch resistance. To ensure the legendary toughness of the MR-G line, the state-of-the-art Multi-Guard Structure incorporates specialized buffers between these components, providing outstanding shock absorption while maintaining a slim, refined profile.

Engineering excellence defines the materials used, with a top bezel fashioned from COBARION®—an alloy four times harder than pure titanium with a platinum-like brilliance—and a bracelet crafted from DAT55G titanium for maximum durability. Beyond its aesthetic beauty, the piece features the advanced 5718 Tough Solar module that draws power through the tiny gaps in the kigumi dial and has a gold-plated retainer plate to reduce electrical resistance. Equipped with Smartphone Link and Multiband 6 radio calibration, this masterpiece remains as functional as it is culturally significant.
