While other models in the series like the thin octagonal GA-2100HC-2A or GA-2100HC-4A, opt for a more transparent clear or green resin to cover the watch case with a highly transparent blue or orange resin for the band. While the sporty GA-2000HC-3A or GA-2000HC-7A take on a matte semi-transparent green or white resin band along with an orange or white color resin bezel that makes the inner case visible. Each bezel is secured by four screws, giving the watches its tough and rugged look. With a multi-sensory approach of analog hands and a digital display, it allows for optimal operational use as well as the design of the hands and graphic figures creating for a powerful face design that enhances readability. G-SHOCK’s signature features like shock resistance, 200-meter water resistance, resin band and case/bezel material, LED light, world time zones, 1/100-second stopwatch and a countdown timer all exist on each model.
