Introducing the first 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. We take it way back with the octagonal bezel and dimpled band design of the original from 1983, all done in metal.

High-density mounting keeps the analogue-digital combination module slim, while still providing the advanced functions you love in a compact profile and comfortable fit. 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.

Slimline module design achieved with high density mounting

Employing a slim Tough Solar powered timekeeping module with Bluetooth® connectivity, the watch maintains the same sense of size as the previous GM-2100 while offering a wider range of functions and full-metal construction. While delivering high utility with Smartphone Link and Tough Solar functionality, the GM-B2100 offers a comfortable fit on the wrist as well.

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.

Dial finishing achieved with microfabrication 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 moulding 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 emphasises the metallic texture for a dial design that complements the watch’s metal exterior.

Three distinctive IP colours for full-metal design

In addition to brilliantly gleaming silver (GM-B2100D), two other options are offered: all-black IP for an intrepid look (GM-B2100BD) and fashionable rose gold IP (GM-B2100GD).

Solar-powered timekeeping with Bluetooth® for enhanced accuracy and reliability

Super Illuminator (high-brightness double LED light) for maintaining watch readability in the dark
