For over 40 years, G-Shock has stood for exceptional durability. While the first models relied primarily on resin and steel, Casio introduced a new stage of development in 2019 with its Carbon Core Guard structure. This technology utilizes carbon fiber-reinforced resin to make cases lighter, slimmer, and simultaneously more durable. But what exactly is Carbon Core Guard technology, and what advantages does it offer in everyday use?
The evolution of G-Shock cases
Traditional G-Shock models are based on a hollow structure. The movement is housed in a shock-absorbing resin case that cushions external impacts. This principle made G-Shock world-famous, but it had one drawback: for maximum shock resistance, the cases often had to be large and bulky.
Why Casio relies on carbon
The most important advantages of the Carbon Core Guard structure
1. Significantly lower weight
2. Slimmer cases possible
Carbon Core Guard compared to resin and steel
| Characteristic | Classic resin | stainless steel | Carbon Core Guard |
|---|---|---|---|
| Weight | Medium | High | Very low |
| Stiffness | Flexible | Very high | Extremely high |
| Corrosion resistance | High | Gut | Very high |
| Building height | Rather massive | Medium | Particularly flat possible |
Popular G-Shock models with Carbon Core Guard
Carbon Core Guard technology is now used in numerous models. The following are particularly popular: GA-2100*, the solar-powered GA-B2100* and the sporting GBX-100*.
| Model | Weight | Special feature |
|---|---|---|
| GA-2100 | approx. 51 g | The famous “CasiOak” |
| GA-B2100 | approx. 52 g | Bluetooth and solar |
| GA-2200 | approx. 57 g | Striking outdoor design |
| GW-B5600 | approx. 53 g | Radio and solar |
Those who want to experience the advantages of Carbon Core Guard technology will find them particularly in the GA-2100– and GA-B2100-Serie They offer an excellent entry point. They combine modern design with low weight and the renowned G-Shock robustness.
