Tough leather material is stitched around a resin core to create a surface that provides plenty of protection against impact while being fashionably elegant. The combination of metal cases and leather bands results in functionally elegant timepieces that look great with a wide range of casual fashions.

Functions include Tough Solar powered operation and Full Auto Double LED illumination for improved readability in the dark. A layer guard structure, and a new type of leather greatly enhance design possibilities for these new G-STEEL models.
