From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes new bi-colour molded models with a sporty mix design theme. With these new models, basic black brand colouring is highlighted by striking colours that are often used for high-tech sneakers and other fashion motifs. Yellow resin is molded onto the inside of the band and each mode also uses yellow for other components.
These models also use orange gradations that are similar to those often seen on various types of sportswear. The GA-400BY has a colourful semi-transparent ring inside its bezel, while the GA-100BY has a gradations pattern on its face. The result of all of this is strikingly colourful designs that are sporty and attractive.
