Casio has launched a new addition to the full metal construction GMW-B5000 series that inherits the form of the first model of the GSHOCK brand of shock-resistant watches. The new Casio G-SHOCK GMW-B5000CS features a laser-carved grid design.

The GMW-B5000 is an epoch-making series boasting an evolved exterior with full metal construction of all outer parts while maintaining the shape of the first G-SHOCK ever—the DW-5000C released in 1983—and adding further advanced functionality including radio wave reception, the Tough Solar power system, and smartphone connectivity.


Since the release of the GMW-B5000 in 2018, Casio has continued to create inventive color schemes and patterns using unique CMF combinations, including black ion plating, aged finish, and camouflage design to ensure the design of the series continues to evolve.


In order to present G-SHOCK brand innovation while maintaining the heritage of that first model, the GMW-B5000CS features a grid design in the image of a time tunnel that connects the past with the future. A “near-future” design with prominent silver lines was forged by applying black ion plating finish to the bezel, band and buckle surface, while bringing out an underlying color scheme using a laser to carve out the latticed pattern.


The Casio G-SHOCK GMW-B5000CS watch is equipped with smartphone connectivity—which allows automatic time correction to be performed four times a day and makes it easy to select cities for world time and adjust other settings easy—and comes with other exceptionally practical features, including a high-luminosity full auto LED backlight.
