The Casio G-Shock MRG 2100 'Hanada-Iro' watch stands out with its bold yet refined design. Built around an octagonal titanium case measuring 49.50 mm in length and 44.50 mm in width with a thickness of 13.60 mm, it commands presence on the wrist while remaining remarkably light at just 122 g. Its dynamic profile is elevated by a cobarion bezel - a material prized for its hardness and scratch resistance. The case back is screw-fastened, delivering outstanding water resistance up to 20 ATM. This robust construction is a testament to exceptional quality and unmatched durability. The anti-reflective sapphire crystal effectively shields the precious dial while offering crystal-clear visibility from every angle.
The dial of this watch is a true work of art inspired by Japanese culture. Its hanada-iro blue color evokes the majestic serenity of an ancient pagoda veiled in mist, drawing directly from the mountain pagodas of the Tohoku region. This distinctive design revives the traditional kigumi wood-joinery technique, expressing timeless sophistication and beauty. The luminescent hands and indices, enhanced by Neobrite treatment, ensure flawless legibility in any lighting condition. The dial also features a perpetual calendar and a date window, seamlessly integrated into the overall design for effortless, everyday use.
