From G-SHOCK, the watches that are ever evolving in pursuit of toughness, this model uses the metal materialsof the square-design 5600 series. The use of a resin material inside the case and a hard stainless steel materialfor the bezel cover creates a high-quality feel while maintaining a lightweight and comfortable fit. The use of aninverted LCD also achieves a more chic finish. While maintaining concepts inherited from the first generation,the 5600 series has been refined to pursue watch quality and evolve the exterior and wearability.
