Founded in Tokyo in 1946, Casio transformed consumer electronics before launching the G-Shock in 1983 with one goal: to build an indestructible watch. The MR-G sits at the very top of that story — hand-assembled at Casio's Premium Production Line in Japan, where aerospace-grade alloys meet the kind of surface finishing normally associated with Swiss haute horlogerie. The MRG-B2100D-2A takes its identity from "Hanada-iro", a traditional Japanese hue expressing the calm of a mountain pagoda seen through morning mist — rendered here across a dial inspired by the kigumi lattice pattern of Japanese woodcraft.

Reference MRG-B2100D-2A is a 44.4 mm MR-G automatic analogue watch, 13.6 mm in thickness and weighing just 122 grams despite its full-metal construction. The indigo blue dial carries a three-dimensional kigumi-inspired geometric pattern, with diamond-polished hour markers and hands coated in Neobrite for low-light readability. The Ti64 titanium case and bezel carry a titanium carbide coating for scratch resistance, while the top bezel is crafted in COBARION — a cobalt-chrome alloy four times harder than pure titanium and finished with Casio's Sallaz mirror-polishing technique. The DAT55G titanium bracelet links are individually polished and fitted with a tight-lock one-press three-fold clasp. The Tough Solar movement powers Multi-Band 6 radio-controlled time synchronisation across six global atomic clock transmitters, Bluetooth smartphone link via the Casio Watches app, and a full perpetual calendar. The sapphire crystal carries an anti-reflective coating. Water resistance is rated to 200 metres.

This Casio G-Shock MR-G Hanada-iro is in near mint condition and comes as a full set.
