Item Description

The GST-B500 is thinner due to the miniaturization of the components used in the module and the high-density mounting technology.

It maintains the high functionality of Bluetooth and solar while keeping the thickness down.

In addition, the carbon core guard structure makes it the thinnest in the G-STEEL series (as of March 2022) while maintaining shock resistance.

It also has a sophisticated design with a strong solid feel that can be matched with various fashion styles.

By adding five different finishes to the bezel, you can enjoy different textures from various angles, and the design is particular about appearance.

With a lineup of five models, three with different face designs, and two with black IP and gold IP, it will be available to a wide range of users.

This G-STEEL series combines toughness and design by fusing different materials such as metal and resin.
