Casio GST-B400 series G-Shock G-Steel Wristwatch, Smartphone Link, Carbon Core Guard Construction, black/blue

Description

Since its release in 1983, G-SHOCK has tirelessly continued to evolve in pursuit of strength.The G-STEEL GST-B400 is a slim and improved design with a low-profile module and carbon core guard construction. This allows for additional smaller parts and a thinner module.While reducing thickness, it also maintains high functionality of Bluetooth® and solar as well as greatly reducing power consumption.In addition, the carbon core guard structure makes it the thinnest in the G-STEEL series (as of March 2021) while maintaining shock resistance.It is o.5 inches (12.9 mm) from the back to the top of the bezel and 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 large stainless steel button that is easy to press.The top bezel and middle bezel have a different finish to give them a separate feel and to improve the watch’s appearance. In addition to two standard models, the GST-B400 with a resin band and a silver case and the all-silver GST-B400D; the GST-B400AD has a red vapor-deposited dial with a black IP bezel, the symbolic color of G-SHOCK, and the GST-B400BD has a black IP case with a band and a blue vapor-deposited dial.The module's power-saving design has improved the quality of the dial with three-dimensional parts and vacuum dials.
