Introducing new compact G-SHOCK models that are great choices for women who prefer mannish G-SHOCK styling.
The iconic square design of the 5600 Series with a metal-covered bezel. All the shock resistance of the GM-5600 in a smaller size for a lightweight and comfortable fit to the wrist.
These designs blend elegance and casualness in ways that make them go great with street fashions. The case and bezel have mirror finishes that enhance the texture of the metal.
This lineup provides a choice of four colors, including two pink gold models, a champagne gold model, and a silver model.
