Casio G-Shock Master of G GWG-B1000-1A3ER

Professional watches designed to challenge the limits of resistance: these MUDMASTER and FROGMAN models from the MASTER OF G line feature tan-colored details inspired by tactical gear. Devoid of superfluous decorations, the understated color palette underscores the line’s commitment to functionality. The FROGMAN GWF-D1000BC features tan-colored details that create a striking effect against an all-black design, evoking the functional beauty of professional equipment. A DLC-coated bezel and black IP-treated front screws enhance the texture of the metal exterior, creating a refined balance between quality and functionality. The watch is also equipped with a composite strap that combines metal and resin, ensuring both strength and lightness. The strap is also extendable, making it wearable over a wetsuit. Every aspect has been designed with actual field use in mind. From the functional structure to the design, the color scheme inspired by tactical gear reinforces the distinctive identity of the MASTER OF G line.
