Introducing G-Shock GM-B2100D-1A, 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 analog-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.
