Introducing the full-metal addition to the continually evolving 2100 line of timepieces that inherit the legacy of the first-ever G-SHOCK, the DW-5000C.

Luxe full-metal construction with a screw-back case, bezel, and band crafted in stainless steel creates a streamlined, minimalist design, while protecting the module from impact when dropped. High-density mounting keeps the analog-digital combination module slim, while still providing the advanced functions you love in a compact profile and comfortable fit.

We take it way back with the octagonal bezel and dimpled band design of the original from 1983, all done in metal. The bezel and band are coated with yellow gold ion plating. The stainless steel bezel — formed three-dimensionally through a time-consuming forging, cutting, and polishing process — is finished beautifully with a circular hairline treatment on the top surface and mirror polish on the slopes.

Pairs with a smartphone via Bluetooth®. Simply tap into the dedicated app for precision timekeeping that keeps you on track. With Tough Solar, a high-brightness LED light and a range of other convenient functions, this is a timepiece that delivers on style and practical utility.


Gold IP to highlight
the exquisite
gleam of the metal.

Gold IP is applied to key stainless-steel components, from the bezel and band down to the side buttons and screws. The bezel features a circular hairline finish applied to its top surface and lengthwise hairline finishes applied to the raised areas on its sides to add variation to the watch’s finish and complement its form.

Iconic design that
stays true to its roots.

The watch design captures the essence of the original G-SHOCK vision in a range of ways, from the octagonal form to the shape of the sides. The iconic dimpled portions on the band are reproduced in metal, with separate hairline and mirror finishes applied to enhance the texture of the material. The case back features a screw-lock construction that exudes solidity, just as on the very first G-SHOCK. Enhanced abrasion resistance is provided with a diamond-like carbon (DLC) coating.


*Due to the screw-lock construction of the case back, the orientation of the logo and lettering on it may not match up perfectly with the dial.

slimmer module for
ease of use and comfort

Optimized, high-density mounting on the circuit board makes possible a slimmer module, helping the watch to maintain the 2100 line’s familiar sense of size in this slim design. Packed with high-utility, enhanced functionality with the inclusion of Smartphone Link and Tough Solar features, the profile of the GM-B2100GD still offers a comfortable fit on the wrist.

High-precision forging
and cutting processes.

The stainless-steel bezel is formed through repeated, painstaking processes of forging and cutting. Crafting with an intense focus on producing precise components, even down to the portions that lie out of sight, ensures an even higher precision fit with the case, including detailed finishing of its back surface.

Dial finish achieved with fine processing technology

Dual-layer dial construction is employed to present the inset dial and LCD portion with distinct finishes of their own. With a minute grind-mark finish and vapour deposition applied to the inset dial ring, laser welding used to secure it to the dial, and more, precision die molding technologies applied by Yamagata Casio deliver an intricate form and meticulously detailed surface finish. In addition, the vapour deposition applied to the dimensional index marks and the indicator hand emphasizes the metallic texture for a dial design that complements the watch’s metal exterior.

Full metal shock-resistant structure with precision refinement

Buffering components made of fine resin are installed between the stainless-steel bezel and case to protect the module from shock. Undergoing meticulous processes of forging, cutting, and polishing, the bezel and case are precisely crafted down to the intricately shaped face, and also to the back, which is the key to the precision fit. Additionally, a three-pronged structure is employed for the lugs on the case to disperse shock to the connective part of the band.
