Box and instruction manual included. CASIO G-SHOCK G-STEEL series GST-B200 G-SHOCK, which pursues toughness, has adopted the newly developed "Carbon Core Guard Structure," boasting high rigidity while being lightweight. This model combines metal materials and carbon fiber reinforced resin to achieve both toughness and a sophisticated design. Equipped with Tough Solar (solar charging), periodic battery replacement is unnecessary. Also, it supports Bluetooth® communication, allowing you to easily perform automatic time correction and various settings by linking with your smartphone. The dial is an analog-digital combination, providing excellent visibility. The design matches a wide range of styles, from business to casual. The use of carbon materials makes it lighter and more compact than previous models, improving the fit on the wrist.
