G-SHOCK offers the first G-STEEL lineup models featuring chronograph performance in analog format. The dial at 9 o’clock has a multi-functional rotating disk that is cut to resemble the thick blades of a jet engine. These watches are equipped with Bluetooth that lets them connect with a smartphone at the press of a button, and acquire time information from an internet time server. The result is accurate timekeeping no matter where in the world you happen to be. Other functions include Tough Solar in combination with CASIO original power saving technology for a stable supply of power, high brightness LED light illumination, and dual dial World Time. The GST-B100D comes with a simple stainless steel band.
