This new addition to the G-SHOCK lineup of watches that are constantly setting new standards for timekeeping toughness features face protectors for a design of classical toughness. Face protectors became the popular G-SHOCK look in the 1990s among young people who were fans of street sports like skateboarding. This new basic G-SHOCK black model takes this classical design to a new level with gold-colored protectors in the style of hip hop artists and b-boys.
