The theme is "The spirit of manufacturing that creates 0 to 1." It is a G-SHOCK full-metal chronograph that expresses the "light of the beginning" that creates new value, using black and gold. The black and gold, which express Casio's spirit of creating "0 to 1," are inspired by the light shining in the darkness. One link in the band, which has been treated with black ion plating, is gold-colored, and "50th ANNIVERSARY" is laser-engraved on it. The outer circumference of the dial has a special design with "0" and "1" printed on it, expressing Casio's manufacturing spirit. The screw-lock crown is designed in the same octagonal shape as the bezel. It contributes to miniaturization while maintaining shock resistance. Furthermore, the slim and highly functional module is equipped with high-density mounting technology, achieving a thinner profile. We also focused on comfort. By connecting to a dedicated app via Bluetooth® communication, it acquires time information and keeps accurate time. It also has practical functions such as Tough Solar and a high-brightness LED light.
