— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
— TRIPLE G RESIST (Shock resistant, Centrifugal force resistant, Vibration resistant)
— Tough Movement (A CASIO-original thin analog movement made possible by hybrid mounting protects against damage and enables auto home position correction that helps keep you on time all the time)

Official Marketing Focus from Casio

Introducing a collection of aviation concept G-SHOCK designed to defy high G forces. A 1/100-second stopwatch is designed to keep accurate time even under the stresses of high G’s that occur during air racing.
The dual-layer face creates a dramatic three-dimensional effect for the three dials. The large face is carefully laid out to provide the look and readability of an aircraft instrument panel.
