G Shock GMAS2100MD-1A Mid-Size Casioak
From G-SHOCK, the toughness watches that are ever evolving in an endless pursuit of strength, this downsized version of the popular GA-2100 model has a simple, thin design that eliminates waste while maintaining a tough structure.
The base GA-2100 model is a thinner G-SHOCK model that inherits the octagonal shape of the first DW-5000C model. The flat face and simple bar indices create a simple yet solid impression.
The colouring is a matte black that goes with any fashion. The glittering metallic bar indices enhance the texture.
