Go metal-clad 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.

Carbon Core Guard structureEver since the first DW-5000C went on sale back in 1983, G-SHOCK has continued to push the limits of timekeeping toughness while creating new and original designs. These new models embody these efforts in an attractively thin configuration.

These new models inherit the octagon form that was also employed for the original DW-5000C. Analog-digital timekeeping comes packed into a no-nonsense simple design without sacrificing G-SHOCK level toughness.High-strength resin material, which is reinforced with carbon fibers, makes it possible to create a case that is a mere 11.8 mm thin, which is the thinnest among G-SHOCK combination models.

Carbon Core Guard Structure
A new carbon core guard structure protects the module by enclosing it in a carbon case. The case is made of fine resin embedded with carbon fibers for outstanding strength and crack resistance.
