Casio G-Shock  - GM-B2100GD-9A

feature

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.
