Casio G-Steel [GM-5600U-1DR]

From G-SHOCK, the watches that are ever evolving in pursuit of toughness, this model uses the metal materials of the square-design 5600 series.
The use of a resin material inside the case and a hard stainless steel material for the bezel cover creates a high-quality feel while maintaining a lightweight and comfortable fit. The use of an inverted 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.
