Features

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, come new rugged style G-STEEL models that feature Carbon Core Guard structures.
This new model adopts tough G-SHOCK styling with a disk indicator at 6 o’clock that shows the current mode and charge level, and a front button that completes the overall rugged look. The disk, a round graphic digital display between 1 and 2 o'clock, and a digital display as 12 o'clock add to both functionality and looks.
The GST-B300 model comes with a resin band.
