This model is decorated with the utility colours of the G-Steel GST-B300, which uses G-Shock's "Carbon Core Guard Structure" that is constantly evolving in the pursuit of durability. The windscreen is made of sapphire crystal and the bezel is made of carbon, which is characterised by its light weight and high rigidity. It is even more robust. The bezel is decorated with a new pattern created by advances in lamination and processing technology, offering an unprecedented design. Green IP is used for the case and front button, and a urethane strap with a green pattern is used for the strap.
