[Product Overview] Shock-resistant structure Born from the development philosophy of "wanting to create a watch that doesn't break even if dropped," the shock-resistant structure overturned the conventional wisdom that watches should be handled with care, and created a new value called "toughness watch." And, in the pursuit of evolution in all directions - structure, function, and materials - we have also achieved design evolution by utilizing the characteristics of resin materials and applying color to the entire watch. Image of the vivid yellow of lightning Yellow, a special color that was explosively popular among the models of the past and became an opportunity for G-SHOCK to merge with youth culture. We have entrusted this special color with the thought that G-SHOCK will continue to be a presence that gives a strong impact to the world, imagining the vivid yellow of lightning that illuminates a space where dark clouds gather.
