Casio G-Shock G-STEEL Radio-Controlled Solar Watch GST-W300G-1A9JF Men’s Black [Official Japanese Product]

Product introduction

G-SHOCK, the brand that continues to evolve in pursuit of toughness, is introducing a new G-STEEL model with a downsized design and expanded design variations. While maintaining the same traditional layer guard structure and functionality, the overall case has been downsized by approximately 90%*. A significant reduction in the module size has enabled a smaller, thinner case, resulting in a mid-size design. Attention to detail is also paid to the finish, with shock-resistant resin indexes featuring a vapor-deposited film applied to the surface, laser-cut, resulting in a face design that combines toughness and beauty. The GST-W310D, featuring a stainless steel bezel and band, features a standard design that emphasizes the solid feel of metal. The GST-W300, featuring a resin bezel, is available in two bands: a metal band and a soft urethane band. The thick soft urethane band enhances comfort and reduces strain on the wrist, even during extended wear. The GST-W300BD boasts a bold, black IP finish, while the GST-W300 boasts a casual design with a resin bezel and stainless steel case, and the GST-W300G boasts a cool, gold-blue IP finish. Other features include Multiband 6, which supports time calibration signals from six stations around the world, a hand retraction function to ensure LCD visibility, and a fully automatic double LED light for excellent time confirmation in dark places. This mid-sized model joins the G-STEEL lineup, which offers a wide range of tough designs thanks to the combination of metal and resin parts. (This is the gold IP model GST-W300G-1A9JF.)

Brand introduction

G-SHOCK established a new concept of toughness in watches. It all began with the passionate belief of its developers in creating a watch that would not break even if dropped, a seemingly foolhardy challenge that overturned conventional wisdom at the time. After more than 200 prototypes and roughly two years of work, the shock-resistant structure was finally completed. This was the birth of the technology that forms the core of toughness. Since then, G-SHOCK has continued to evolve endlessly, pursuing even greater toughness in every aspect: structure, materials, and functionality.
