Casio to Release Limited-Edition Timepiece Celebrating MR-G 30th Anniversary

TOKYO, September 24, 2026 — Casio Computer Co., Ltd. announced today the release of a new MR-G timepiece, adding to the flagship line of the G-SHOCK brand of shock-resistant watches. The new MRG-B2100HR-1A, featuring a dimensional latticework dial inspired by kigumi^*1 and finished in platinum leaf, is available in a limited edition of only 800 pieces worldwide.
*1 Kigumi is a traditional Japanese construction method and woodworking technique used for wooden joinery without the use of nails or other metal fittings.

Based on the concept of delivering the ultimate in toughness-driven watches, the MR-G line is the pinnacle of the G-SHOCK brand, meticulously crafted down to the smallest detail and incorporating state-of-the-art technology and master metalworking techniques. To commemorate the 30 years that have passed since the debut of MR-G in 1996, Casio drew the inspiration for this timepiece from metal leaf, an art that embodies both tradition and innovation. The resulting design expresses a strength that transcends time and embodies the theme of haruka (which translates to “eternity”). Metal leaf artist Hiroto Rakusho created an original artwork for the theme, which together with the timepiece design brings the world of haruka to life.

Built on the popular shock-resistant MRG-B2100 with its octagonal bezel, the new MRG-B2100HR-1A features a dimensional latticework dial. Each limited-edition timepiece is adorned with platinum leaf personally applied by Rakusho himself. Powdered platinum leaf creates a subtle shimmer and gradations of light and dark that impart a sense of depth and give each timepiece its own distinct character.

The bezel and bracelet evoke the brilliant visual world of Rakusho’s artwork, with metal leaf-inspired textures rendered using structural color technology.^*2 Precision laser processing at the micron level produces beautiful colors that change depending on the viewing angle. The design brings together traditional techniques and cutting-edge technology to highlight the beauty of metal leaf.
*2 Structural color is the phenomenon in which iridescent colors appear on butterfly wings, minerals, and other objects. For this timepiece, structural color is achieved using an ultrashort-pulse laser.

The bezel is formed from 27 separate components, each carefully polished before precision assembly. The bezel and bracelet employ the super-hard alloys COBARION™^*3 and DAT55G,^*4 respectively. Together, the finishes and materials deliver both refined metallic beauty and toughness.
*3 COBARION is a trademark for a cobalt-chromium alloy manufactured exclusively by Eiwa Co., Ltd.
*4 DAT is a registered trademark of Daido Steel Co., Ltd. in Japan.

Driven by the Casio Purpose — “Through the power to put wonder at hand, bring new levels of joy to lives one by one” — Casio has brought unprecedented value to the world. Looking ahead, Casio will continue to go beyond the practical function of timekeeping in watches, offering diverse functions and distinctive designs that deliver new joys of watch-wearing and thrills of discovery.
