Born from a dream of "creating a watch that never breaks." It was over 30 years ago, a CASIO engineer won the battle against the laws of nature. He designed a watch that would resist centrifugal and impact forces, as well as high water pressure. Since then, the name G-SHOCK has become a byword for independence and pushing the limits. G-SHOCK watches are the most durable digital and analog-digital watches in the industry, trusted by military personnel, law enforcement, surfers and outdoor enthusiasts around the world. Along with this, G-SHOCK is highly touted in the fashion world, worn by icons in hip-hop, sports, and design. With limited edition collaborations being released often, you can always find a G-SHOCK that matches your personality and style.
