The G-Shock DWE-5600 with Carbon Core Guard (carbon fiber-reinforced case) is a special edition that is used as the base for limited edition box sets that include multiple bezels and bands. The DWE-5600 uses the same module as the DW-5600 but the bezel attaches to the case without screws and can be removed quickly with the included tool. The bands have quick-release levers. The DWE-5610 with Carbon Core Guard is also used as the base for the “My G-Shock” watch customization service by Casio Japan.
