From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, come new colours for the G-Steel lineup that combines different materials.
The Bluetooth® connect button, the GSTB100 iconic disk indicator at 9 o’clock, and the G-SHOCK logo are accented with colors that are typical of those seen on high-tech gadgets. The case has a black ion plated (IP) finish, which combines with the edgy GST-B100 design to create a pair of exciting new models.
