From G-SHOCK, the watch that has constantly been testing new limits in timekeeping toughness since 1983, come new DW-B5600 models with Smartphone Link. The DW-B5600G is a Smartphone Link model based on the popular standard 5600 series. Both models include a choice of semitransparent black and turquoise blue coloring that looks great with both urban and sport fashion. These watches are Bluetooth®-capable, which means they can link up with a G-SHOCK app installed on your phone. Smartphone Link packed into tough and rugged designs makes these models everything you would expect a G-SHOCK timepiece to be.
