G-Shock Watch Full Metal Mens GMW-B5000CS-1ER. This laser engraved model is a new variation on the full metal square face GMW-B5000 that inherits plenty of the DNA of the original G-SHOCK DW-5000C. The surface of the stainless steel case and band of the base model GMW-B5000D is given a black IP finish, which is then laser etched to create an innovative Grid Tunnel pattern. The Grid Tunnel finish of this model adds a new modern touch to the timeless, classical design of the 5000 Series G-SHOCK. As with all GMW-B5000 models, features include Tough Solar Power, Multi Band 6 Radio Control, Bluetooth Smartphone Link and STN LCD Display.
