Casio G-Shock G-STEEL Radio-Controlled Solar Watch GST-W310D-1AJF Men’s Silver [Official Japanese Product]

Product introduction

Brand Description: G-SHOCK pioneered a new concept of watch toughness. It all began with the developers’ passionate belief in creating a watch that would survive a drop, a seemingly foolhardy challenge that overturned conventional wisdom at the time. After over 200 prototypes and approximately two years of work, the shock-resistant structure was perfected. This marked the birth of the technology at the heart of toughness. Since then, G-SHOCK has continued to evolve endlessly, pursuing even greater toughness in every aspect: structure, materials, and function. G-SHOCK continues

to evolve in its pursuit of toughness, and now the new G-STEEL model features a downsized design and expanded design variations. While retaining the same layer guard structure and functionality as the previous model, the entire case has been downsized by approximately 90%*. A significant reduction in the module size allowed for a smaller, thinner case, resulting in a mid-size design. Attention to detail, including the shock-resistant resin indexes, features a vapor-deposited coating applied to the surface, laser-cut, resulting in a face design that combines toughness and beauty. The GST-W310D features a stainless steel bezel and band, creating a standard design that emphasizes the rugged feel of metal. The GST-W300, featuring a resin bezel, is available in two bands: metal and soft urethane. The thick soft urethane band enhances comfort and reduces strain on the wrist even during extended wear. The GST-W300BD features a bold black ion-plated finish, the GST-W300 combines a casual design with a resin bezel and stainless steel case, and the GST-W300G features a cool gold and blue ion-plated finish, expanding the watch’s range of options. Other practical features include Multiband 6, which supports standard timekeeping from six stations around the world, a hand-shift function to ensure LCD visibility, and a fully automatic double LED light for easy time checking in dark places. Introducing a mid-sized model of the G-STEEL series, which combines metal and resin parts to expand its range of tough designs. (This is the GST-W310D with a stainless steel bezel and band.)

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.
