GSTB400CD1A3

My GShock

The GSTB400CD1A3 has a bezel with a new green ion-plated (IP) finish, which brings out the texture of the metal. The slim GSTB400 design is made possible by advances in component miniaturization and thinning of its modules, without sacrificing any Bluetooth® or solar functions. Power consumption has also been significantly reduced. In terms of design, the number of button guards has been reduced as much as possible, enabling the use of large stainless steel buttons that are slim yet easy to operate. The top bezel has been given five different finishes, while the middle bezel has been given four different finishes, which creates an elegant effect and changes the appearance of the texture of the metal depending on the viewing angle
