Casio ‘Tough Chronograph’ GST-B100 Watches

Casio was pleasantly surprised when the demand for their G-Shock watches was so great that they expanded to higher-end styles. One such iteration is the Casio G-Shock G-Steel ‘Tough Chronograph’ GST-B100. Using Bluetooth connectivity to sync with your smartphone four times a day to assure the most accurate time possible; it even registers time zone changes and adjusts accordingly.

Along with the time set, the app for the GST-B100 controls alarms, a find-my-phone detector, reserve power register, and more. It uses the Casio Tough Solar technology to produce power. At 53.8mm wide and 14.1mm thick, the dial provides adequate visibility for the three subdials.

Also, this iteration does not crowd the watch face with a digital readout alongside the analog. It comes with several strap options including a steel bracelet and a rubber strap.
