[Casio] G-Shock Watch [Domestic Genuine Product] G-STEEL Smartphone Link Carbon Core Guard Structure GST-B400-1AJF Men's Black

Description

Since its launch in 1983, G-SHOCK, the tough watch, has continued to evolve in pursuit of insatiable strength. The G-STEEL GST-B400 is slim and has an improved design thanks to its thin module and carbon core guard structure. The components have been made even smaller and the module has been made thinner. While keeping the thickness down, the watch maintains high functionality such as BluetoothⓇ and solar power, and power consumption has been significantly reduced. In addition, the carbon core guard structure makes it the thinnest in the G-STEEL series (as of March 2021) while maintaining its shock resistance. At 12.9 mm from the back to the top of the bezel, it is more than 1 mm thinner than the GST-B100. In terms of design, the button guard has been reduced to the minimum, resulting in a slim yet easy-to-press large stainless steel button. The top bezel and middle bezel have different finishes, allowing you to enjoy the difference in texture, resulting in a finish that is particular about the appearance. The color variations include the two standard models, the GST-B400 with a resin band and silver case, and the all-silver GST-B400D, as well as the GST-B400AD, which combines a red vapor-deposited dial, the symbolic color of G-SHOCK, with a black IP bezel, and the GST-B400BD, which has a black IP case and band and blue vapor-deposited dial. The power-saving module has improved the texture with three-dimensional parts and vapor-deposited dial. The G-STEEL series combines different materials, metal and resin, to achieve both toughness and design.
