stylish and tough, the slimmest G-STEEL yet*
*Based on a Casio survey as of February 2021.
Featuring the G-STEEL GSTB400 trademark structure, which combines the strength of carbon with the quality of metal, but now in the slimmest profile ever. The design offers enhanced texture in the dial and the convenience of smartphone connectivity, accelerating the advance of G-STEEL as a multifunction analogue watch.
DESIGN & TECHNOLOGY
Carbon Core Guard structure, both strong and light
Offering strength, lightness and excellent weather resistance, a carbon fibre-reinforced resin case protects the module. Additionally, buffering components made of resin mounted between the upper and lower bezels help absorb external shocks.
Newly developed module delivers slimness and energy-savings
Optimised, high-density mounting of the circuit board structure made it possible to slim the module. A substantial reduction in power consumption was also achieved by reducing the number of watch hands to two and adopting a low-power Bluetooth® system. The ability to solar charge with an opaquer dial allowed for a high degree of freedom in dial design.
Metal band with double slide lever for easy band changes*The GSTB400 uses a single slide lever.
