The GSTB100-1A is one of the latest additions to G-Shock’s ever-expanding G-Steel Lineup. It is the first line of G-Steel watches to utilize Bluetooth connectivity, making it a mild smartwatch of sorts. The watch features a red button at eight o’clock that connects to G-Shock’s connected phone app via Bluetooth with one push; from there, users can set alarms, check their battery level and change time zones from their phone. It even allows the watch to be used to locate a misplaced phone and, because it links to a smartphone’s accurate atomic timekeeping, when connected it can automatically adjust to the correct time.

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, come new colors for the G-STEEL lineup that combines different materials.

The Bluetooth® connect button, the GST-B100 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.
