Stronger from the Core: Casio G-Steel Carbon Core Guard GST-B200
As featured on Revolution, June 4, 2019
The Core. You’ve probably heard it in fitness and workout articles, or when you’re watching YouTube videos about planking. Your core supports the rest of your body and so strengthening it is crucial to your physical health. In watchmaking, the core refers to the movement within the watch case, which drives all of its operation.
Watch cases are designed to support and protect the movement of a watch while displaying its functions, but within the case, there are still opportunities for the movement to be damaged, through shock, heat and cold environments, water and dust, among other factors. When Mr Kikuo Ibe invented the G-Shock series of timepieces, he had the aim of creating a watch that would meet the requirements of a 10-metre drop onto a hard surface, and 100-metre water resistance. Casio’s G-Shocks have more than met this expectation, and deliver greater performance than the original G-Shock watch, with Bluetooth and other functionality built in.

In the first generation of G-Shocks, the cases were crafted in resin for ruggedness, and a second generation of G-Shocks in metal offered enhanced structural support. The third wave of G-Shocks are now constructed in carbon fiber for shock resistance and a high strength-to-weight ratio.
What is Carbon Core Guard?
Casio's new shock resistant structure that protects the time modules inside with a carbon fiber reinforced resin case
In the G-Shock’s Carbon Core Guard, layers of carbon fibre are bonded with an epoxy resin, pressed together and moulded into a case structure. This new inner case has multiple benefits as it can be shaped into smaller diameters, is lighter and stronger than resin and removes the need for shock-resisting button guards, simplifying the structural integrity of the case.
