Casio G-Shock MT-G MTG-B3000BD-1AJF Men’s Watch – JDM Solar-powered, Radio-controlled, Bluetooth, Black Dial, Steel and Carbon – Dual Core Guard, Sapphire Crystal, WR 200M (51.9 x 50.9 x 12.1 mm)

The Casio G-Shock MT-G MTG-B3000BD-1AJF (JDM edition for the Japanese domestic market, manufactured by Yamagata Casio, Japan) features a black design with a bezel and bracelet finished in dark grey ion-plated metal and a dial moulded using nanoprocessing technology. Its analogue display features three central hands, a date window and three sub-dials for dual time, 24-hour format and day of the week, powered by Tough Solar and featuring dual time synchronisation via Multiband 6 radio frequency and Bluetooth connection to the CASIO WATCHES app, as well as a Neobrite coating and white Super Illuminator LED backlighting.

Measuring 51.9 x 50.9 mm, it achieves a slim profile of just 12.1 mm thick and weighs 148 grams, thanks to its high-density module and the Dual Core Guard structure with Triple G Resist certification, where the three-dimensional stainless steel case back protects the carbon-fibre-reinforced resin core and acts as lugs and guards for the buttons and the screw-down crown. It features sapphire crystal with an anti-reflective coating, a solid strap made of hollow stainless steel and resin with a triple-fold clasp and a tool-free, one-touch quick-change system, offering water resistance to 200 metres and up to 5 months’ battery life under normal use (18 months in power-saving mode).
