THE TECHNOLOGY...
Stylish & Sophisticated looks
The watch features a stainless-steel bezel in a sophisticated new shape. Attention to detail and material quality are paramount for the G-STEEL, featuring unique finishing techniques like hairline, mirror and polishing, highlighting an impressive array of surface textures that captivate the eye from every angle.
Tough Solar & Improved Readability
The GST-B400 is powered by G-SHOCK Tough Solar power system, charged by both real and artificial light sources. To ensure great readability, as well, a dial indicator at the 9 o’clock position display the mode, battery level and more.
Metal Band with Double Slide Lever
This allows quick and easy change of the bands.
Slimness & Energy-Saving Module
Optimised, high-density mounting of the circuit board structure has made it possible to slim the module of the new GST-B400. 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.
