This model from the "GULFMASTER" series, designed for use in the ocean—one of the harshest natural environments on Earth—features a design that emphasizes G-SHOCK's brand color, black. The forged bezel, with its raised lettering and machined finish, is coated in black IP, and the index markers (excluding the top, bottom, left, and right sides) are also black. Furthermore, the LCD uses an inverted display. While ensuring visibility, it expresses strength and a ruggedness. Additionally, subtle blue accents on parts of the second hand and the small hands on the sub-dials evoke the feeling of the sea. The Gulfmaster expresses the tough spirit of men who challenge the extremes, using G-SHOCK's brand color.
