The GST-B500 line brings together smaller components and high-density mounting, continuing to deliver Bluetooth connectivity and solar power charging, but in an even slimmer profile. The Carbon Core Guard absorbs external shocks for true G-STEEL toughness, and the comfortable fit complements your unique way of life. Downsized button guards offer slim yet ample buttons that are easy to operate.

The bezel is treated with multiple finishes to deliver exceptional metal textures from every angle, for a truly sophisticated presentation with its own special look.
