These new Solar Atomic models are based on the original DW6900 model, G-Shock’s best-selling case design and one that is so popular among followers of street fashions. With these models, a Solar Atomic Timekeeping system was employed without changing the basic design of the watch. This makes it possible to generate power to keep the watch running with extreme accuracy and minimal exposure to normal lighting. This simple & colorful design really captures the essence of the basic G-Shock. White Resin Band and a Digital Dial Code.
