Go metallic faced in cool, sophisticated color with a slim GA-2100 that inherits the design concept of the first-ever G-SHOCK. The polished gleam of metallic color and the iconic octagonal form of the DW-5000C, the original G-SHOCK, come together in a rugged digital analog combination timepiece measuring just 11.8mm from bezel to case back. A slim design with the same tough G-SHOCK construction. Finished beautifully with a circular hairline treatment, the dial is also treated with gold-color vapor deposition, as are the index marks. Add a bezel and band in glossy black for a timepiece that makes a bold and elegant statement.
