The G-Shock GST-B600 continues the downsizing trend of the G-STEEL line and is currently the thinnest G-Shock series for men. At just 11.4 millimeters thick, the GST-B600 is even slimmer than the GA-2100 which previously held the title. The width of 42.3 mm is also smaller than other analog G-Shock series and closer to the size of traditional wristwatches. The GST-B600 is powered by Tough Solar power and has Bluetooth connectivity for additional functions like automatic time correction, time and place log, and reminders.

(Casio lists the compatible band size for the GST-B600D-1AJF with stainless steel band as 125 to 185 millimeters, which we believe is probably a mistake. The compatible band size listed for the models with a resin band is 140 to 205 mm.)
