Casio G-Shock  -  GST-B100-1A

Features

A G-STEEL model featuring a solid case, a chronograph with an analog display, and a urethane band designed with a motif of heavy jet engine blades.
A dual-coil motor in a rotating disc dial placed at 9 o'clock moves the dial blades and exudes a functional beauty. In addition to the alarm on/off function and using the rotation to show the stopwatch, etc., it also functions as a battery indicator, contributing to a tough chronograph.
The layer guard structure and high-density mounting technology have allowed the module to be smaller and thinner, improving wearability and overall watch quality.
It is also equipped with Bluetooth® connectivity that enables accurate time acquisition via your smartphone. Its Tough Solar feature allows it to run stably, and it is also equipped with practical functions such as high-brightness LEDs and dual-dial world time.
