Durable Casio G-Shock men's watch with a black dial and strap. Tough Solar power system for reliable, long-lasting charge. Shock-resistant construction and multi-function chronograph for everyday performance. Sleek black design that pairs with casual and active looks. 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.
