Exuding a sleek, sharp, and bold aesthetic, the G-Shock CasiOak Metal Watch GM2100-1A is a testament to G-SHOCK's pioneering spirit. This timepiece is a revamped, metal-clad version of the original iconic design, setting a new benchmark for style and durability.

Forged in Stainless Steel

Constructed with a strong bezel forged in stainless steel, this watch showcases a rounded hairline finish, exuding super style from every angle.

Exceptional Dial Design

The dial of the watch is treated with a vapour deposition finish which results in a meticulously detailed metallic look that perfectly complements the classic metal G-SHOCK timepiece.

Unique Wristband Texturing

Adding to the watch's distinctive appeal is the detailed square dot texturing on the wristband. Made from casual urethane materials, the texturing takes the wristband's design up a notch, making the watch a standout piece in any ensemble.
