Professional gear built to challenge the limits of toughness, these MUDMASTER and FROGMAN timepieces from the MASTER OF G line feature tan accents inspired by tactical equipment. Stripped of unnecessary decoration, the restrained colour palette reinforces the line’s commitment to true utility.

The FROGMAN GWF-D1000BC uses tan accents to striking effect in an otherwise all-black design that evokes the functional beauty of professional gear. A DLC-coated bezel and black IP-treated front screws enhance the texture of the metal exterior, achieving a refined balance of quality and functionality. The watch also employs a composite band that combines metal and resin for both strength and light weight. The band is extendable in two increments, so it can even be worn over a wetsuit.

Every aspect is designed with actual field use in mind. From construction and functionality to design, the colour scheme inspired by tactical equipment reinforces the distinctive identity of the MASTER OF G line.
