 Design Concept

A premium evolution of the popular GA-2100 "CasiOak" line, the GM-2100B-3AJF stands out with a metal-covered octagonal bezel and refined industrial aesthetics.

• The bezel is made of stainless steel with a circular hairline finish and dark gray IP coating, providing a sleek, modern feel.

• The vapor-deposited dial adds a metallic sheen and crisp depth to the minimal display.

• A textured checkered resin band subtly shifts in tone and texture, offering both comfort and a premium look.

This is a perfect crossover of G-SHOCK toughness and urban elegance, ideal for daily wear, casual business, or fashion-forward looks.
