Casio announced the MRG-B2100HR in September, a limited run of 800 pieces, marking three decades since the MR-G, the flagship line within G-SHOCK, debuted in 1996. The dial takes its cue from kigumi, the Japanese joinery technique that locks wood together without nails or metal fittings, translated here into a dimensional latticework finished in platinum leaf.
Metal leaf artist Hiroto Rakusho built an original artwork around the theme of haruka, meaning eternity. Powdered platinum leaf gives each dial its own depth.
Twenty-seven separately polished components make up the bezel, built from Cobarion, and the durable, high-end bracelet uses DAT55G. Both sit on the MRG-B2100’s established octagonal case, and both carry a laser-etched finish that shifts colour depending on the angle it catches, echoing iridescence. Underneath the artistry, the watch keeps the everyday resilience the MR-G name is built on: shock and magnetic resistance, 200 metres of water resistance. The watch combines Tough Solar power, Multi-Band 6 radio-controlled timekeeping, and Bluetooth connectivity. None of that is new for the line. The premium buys the dial, the metalwork, and the exclusivity.
Earlier in January, the brand opened the anniversary with the MRG-B2100D, a full-metal watch in hanada-iro, a traditional Japanese blue, with a dimensional latticework dial drawn from kigumi. The design took its inspiration from a national treasure, a five-storey pagoda in Yamagata Prefecture, where MR-G watches are built, seen through drifting morning mist.
In May, the anniversary got a second flagship in the MRG-BF1000EB, a special MR-G FROGMAN diver inspired by the brinicle, the vertical columns of ice that form beneath polar sea ice. Its bezel, cut from Cobarion and hand-faceted under master artisan Kazuhito Komatsu, carries a spiral pattern finished in blue arc ion plating to evoke the phenomenon’s swirl.
This year, Casio also pushed the rest of the G-SHOCK catalogue into new territory, starting with a design overhaul of the MT-G line.
First released in 2025, the MTG-B4000 has a frame developed by Casio using a design process that combined human engineers and generative AI. The line hasn’t stayed still since. A composite-band version, the MTG-B4000D-1A, arrived in Japan in January 2026, followed in May by two more variants. The MTG-B4000B-1A has a multi-layered carbon frame, red accents, and a resin band. The MTG-B4000BD-1A swaps that for a layered composite bracelet of stainless steel and carbon fibre-reinforced resin finished in black ion plating.
In April, Casio added the GBX-H5600 to its G-LIDE lineup, the first watch in that series to carry a heart rate monitor. An optical sensor enables heart-rate measurement, while the watch’s motion sensors support activity tracking, such as distance, calories, and step count. The case back uses carbon fibre-reinforced resin to reduce weight.
Casio launched two colourways in May, a black GBX-H5600-1 and a blue GBX-H5600-2, both built around the translucent resin bezel that has defined G-LIDE watches for years. In July, the line got its first post-launch colourway: pro surfer Kanoa Igarashi’s fourth signature model.
The GBX-H5600KI-5 takes its brown, mixed-colour moulding from the cliffs near Igarashi’s training grounds in Portugal. His signature appears on the face and case back, and his WSL surfer number, 50, runs along the lower band, a number he picked for its connection to the meaning of his own surname.
Casio unveiled the EFK-200 in June ahead of a July launch, its third mechanical Edifice release in under two years. The case carries separate mirror and hairline polish, set under a cushion-shaped bezel with cut corners. Two of the five references, the EFK-200XPB and EFK-200CD, use forged carbon for their dials, a material more commonly found in high-performance car interiors. The EFK-200D and EFK-200DG go in a different direction; their dials are electroformed and finished in gradated colour.
All five references run on a Japanese automatic movement with roughly 42 hours of power reserve, visible through a transparent case back. The EFK-200XPB-1A is drawing the most attention: built with Toyota Racing, finished in forged carbon with rose gold-tone accents against an all-black case, it’s the first watch to come out of that automotive partnership.
Casio turned to music in May with two watches built around XG, the seven-member group made up of Jurin, Chisa, Hinata, Harvey, Juria, Maya, and Cocona. The group became G-SHOCK’s global ambassadors in July 2025.
The GM-S5600XG, built on the 5600 line that traces back to the original G-SHOCK, wears glass finished in rainbow vapour deposition that shifts colour with the angle of view, set against a black band and bezel. The GMA-S110XG takes a bolder approach; its vivid pink band and bezel are built through Garal colour moulding, a technique that blends different coloured resins into a marbled pattern unique to each unit.
