Immerse yourself in brilliant iridescent color, the first-ever G-SHOCK with full-surface gradated crystal finish evoking reflected sunlight. Rainbow vapor deposition reproduces the midsummer sky at dusk, changing hue moment by moment depending on the light. Each crystal gleams with a singular radiance, delivering one-of-a-kind timepieces, each with its own unique color pattern. * Actual product may differ from the color gradation pictured here. * Because these models feature specially treated crystal watch glass, the dial may be easier to read at certain viewing angles.
