Introducing the GMW-B5000 line of full-metal timepieces that delivers state-of-the-art functionality in a design true to the very first G-SHOCK.

The GMW-B5000-3 inherits this legacy and carries it forward in an effortlessly refined full-metal G-SHOCK design with a silver gleam accented by an outline of fresh green.

Buffering components made of fine resin installed between the stainless-steel metal bezel and case deliver a shock-resistant structure in a full-metal timepiece. High-density mounting technology keeps this watch just as slim and compact as other GMW-B5000 designs.

The solid screw-lock case back, finished with DLC coating, delivers even greater abrasion resistance. Dimpling applied to metal band pieces reproduces the look of the resin band of the very first G-SHOCK, while the film solar panel and STN-LCD digital display provide exceptional visibility and an easier read.

This innovative timepiece delivers full-on functionality, as well. Download the dedicated app to pair with your smartphone via Bluetooth®. With Multiband 6 radio control for automatic precision timekeeping, Tough Solar for stable operation of functions, high-brightness full auto LED backlight, world time, day display in six languages, and more, you’ll be at peak performance.
