G-Shock GM-2100-1AER watch

The watchmaking brand Casio has developed over the course of its history the category of sportiest watches, the Casio G-Shock collection. As we have mentioned, Casio is evolving its watches in all directions. We have developed several materials compatible with our concept of absolute hardness. The technology has pursued thickness reductions on a scale of 1/100 mm for greater precision and attractiveness in the design. Distinctive techniques have been applied to traditional skills in original ways to achieve a new manifestation of Japanese beauty. Casio continues to develop its advanced technologies and skills as a manufacturer to extend the limits of the evolution of watches. G-SHOCK established the then unprecedented concept of hardness in watches. Against all conventional thinking, there are no limits in the pursuit of this objective. Even now, Casio is challenging to create a new kind of hardness and is approaching an idealized perfection with materials resulting from research in aviation and astronautics.
