Introducing the full-metal chronograph addition to the continually evolving 2100 line of timepieces which inherit the legacy of the first-ever G-SHOCK, the DW5000C.
We take it way back with the octagonal bezel and dimpled band design of the original from 1983, but all done in metal with stainless-steel case, bezel, and band.
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 bezel — formed three-dimensionally in 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.
The delicate moulding and vapour deposition of Casio ultra-precision processing technologies add sophistication and quality to the indexes and inset dial rings.
The screw-lock crown is designed in the same octagonal shape as the bezel for a more compact case with no sacrifice in outstanding G-SHOCK shock resistance.
High-density mounting keeps the 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 both superior style and practical utility.
