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 color 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 color scheme inspired by tactical equipment reinforces the distinctive identity of the MASTER OF G line.

FROGMAN GWF-D1000BC

Tan accents inspired by tactical gear are used to striking effect, expressing the true utility that the MASTER OF G line is committed to delivering. Harmonizing with the otherwise all-black color scheme, the design evokes the functional beauty of professional tools. A diamond-like carbon (DLC) coating is applied to the bezel and black IP to the front screws to enhance the metal materials’ textural appeal.

ISO 200-meter water resistance: Supporting professional diving

In combination with the screw-lock case back providing a tight seal, the stainless-steel case, built to withstand high water pressure, ensures compliance with ISO standards for water resistance. The crystal uses sapphire glass thicker than standard. The iconic FROGMAN diving frog engraved on the case back symbolizes the unique identity of the only diver’s watch in the G-SHOCK lineup.

H-links embedded with metal components connect to center links made of fine resin to deliver both strength and light weight. The band is extendable in two increments as well, so it can even be worn over a wetsuit. The buckle features a screw-type adjustment configuration that enables the length to be fine-tuned.
