G-SHOCK announced new slim and light G-SHOCK G-STEEL GST-B500 watch. This innovative watch design is made possible by a thin module and a carbon core guard structure.

The thing module of this GST-B500 watch is made possible by downsized components and high-density mounting technology.

The carbon core guard structure, has a carbon-fibre reinforced resin case to protect the module, making this GST-B500 the lightest model of the G-STEEL series as of March 2022.


These sophisticated G-SHOCK GST-B500 designs go well with a variety of different fashion and styles. The bezel’s surfaces have different finishes, which creates an elegant effect and changes the appearance of the texture of the metal depending on the viewing angle. There are a few different colour designs, three silver colours, one black colour, and one gold colour.


For the silver colour models, they have three different colour dials, all black, black with a red accent and green.
