G-SHOCK GM-2100M-1ADR G-STEEL

Streamlined design, striking functional beauty, shock-resistant construction — a toughness-driven G-SHOCK with a monochromatic modern industrial look.

The digital GM-5600, with iconic shape and metal bezel, and the analog-digital combination GM-2100 take on an achromatic color scheme that highlights the chic beauty of simplicity and functionality. 

The textured pattern of the metal bezel and the touch of red for the function label, symbolizing G-SHOCK dedication to total toughness, showcase pure functionality in design.

The bezel’s unique form features openings that allow the center case inside to show through, flaunting the core technology of G-SHOCK: its shock-resistant structure. 

Delivering both streamlined, universal design and practical utility, this is a timepiece to enjoy for years to come.
