Casio G-Shock G-STEEL Radio-Controlled Solar Watch GST-W310-7AJF Men’s White [Official Japanese Product]

Product introduction

G-SHOCK, the watch brand that continues to evolve in pursuit of toughness, is introducing new mid-size models in its G-STEEL lineup, which offers expanded design variations. The lineup includes four models based on the GST-W310/GST-W300G, which are equipped with advanced functions and feature urethane bands. The GST-W310, featuring an edgy stainless steel bezel, comes in two monotone models with black or white dials and bands. The use of a light-dispersing solar cell enhances the beauty of the dial. The GST-W300G, featuring a solid resin bezel, is available in two models: one with a bold all-black look and one with a bold two-tone finish featuring red bands, further expanding the design variations. These new models offer additional color variations for the mid-size G-STEEL. (This model is the GST-W310-7AJF.)

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.
