New CASIO G-SHOCK GA-B2100-1A1JF

I purchased this in August 2025.

Domestic genuine product

New, unused, comes with warranty and delivery documents

The octagonal form of the GA-2100, which inherited the design concept of the first-generation G-SHOCK, has been retained, and a smartphone link and tough solar have been added.

To correspond to the increase in the number of parts due to high functionality, a new thin module with optimized board layout has been developed.

By combining a carbon core guard structure that achieves both strength and lightness, the size of the model is kept as it was.

A two-layer dial configuration is adopted, emphasizing the three-dimensional feel of the liquid crystal and the indial.

Different surface treatments are applied to the base face and the indial, and attention is paid to details to enhance the texture of the dial.
