Casio GM-B2100SD-1ADR

Introducing a full-metal addition to the continually evolving 2100 style 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 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.

Buffering components made of fine resin are installed between the bezel and the case for a shock-resistant structure with a full-metal exterior.

The dial’s delicate molding, achieved with fine processing technology from Yamagata Casio, is paired with indexes with a silver-color vapor deposition finish for an eye-catching design and even easier read.

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.
