Designed entirely in the brand colour of black, the model's single-tone colour gives it a finish that highlights the texture of the resin band material.

The base model is the AW-591, with its compact and practical design. The simple matte black finish emphasises the shape of the watch itself.

Black ion plating has also been used on the clasp, buttons and the bezel area to add black to even the finest of areas.

This model expresses the essence of G-SHOCK through its use of colour and employs a tough-looking, almost rugged, design.
