Every one of the 800 dials on the new MRG-B2100HR-1A is finished by one pair of hands. Casio announced the watch on September 24, 2026. Its three-dimensional latticework dial takes its pattern from kigumi, the Japanese joinery method that fits wood together without nails or metal fittings, and metal leaf artist Hiroto Rakusho applies the powdered platinum leaf, called sunago, to each dial himself. Casio says the powder produces gradations of light and dark that come out differently on every piece.
The watch marks 30 years since MR-G, the top line of G-SHOCK, arrived in 1996. Casio built it on the octagonal-bezel MRG-B2100 and gave the bezel and bracelet textures meant to read as metal leaf, produced with structural colour rather than pigment. An ultrashort-pulse laser works the surface at micron scale so the colour shifts with viewing angle, the same phenomenon that colours butterfly wings and minerals. The bezel is assembled from 27 separately polished components in COBARION, a cobalt-chromium alloy made only by Eiwa, and the bracelet is Daido Steel’s DAT55G. Casio’s theme for the piece is haruka, which it translates as eternity.
Casio’s Japanese release puts the price at JPY 1,100,000 including tax, which works out to roughly $6,930 USD at current exchange rates, with an on-sale date of November 13, 2026 and production capped at 800 pieces worldwide. The reference has a page on Casio’s international G-SHOCK site, though Casio has not published a US price or detailed availability outside Japan.
