G-SHOCK TAN-ACCENTS | October 2026

A pair of tan-accented MASTER OF G timepieces

The MASTER OF G professional line is defined by a passion for challenging the limits of toughness. This pair of MUDMASTER and FROGMAN watches employ accents in a shade of tan, a utility colour commonly used for rugged gear, to create appearances that exude practicality. Eschewing any decorative elements, the accents set off the designs with an understated sense of presence against an otherwise all-black design. Each of these timepieces powerfully projects the MASTER OF G identity with its ongoing commitment to delivering true, ultimate practicality.

MUDMASTER GWG-B1000

A tan hue widely employed in tactical gear highlights dial components and feature indicators on the bezel, emphasising the practicality in actual field use that the MUDMASTER line is committed to delivering. The multi-component case exteriors are finished in black with varying textures for individual materials and components. Paired with a matte olive-green urethane band, the finishing expresses an intrepid yet understated sense of toughness.

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.

Shock, dust, mud, and vibration resistance: Tough structure designed to deliver mastery of the field

The watch employs a guard structure combining components made from different materials, including stainless steel and carbon fibre-reinforced resin. Sophisticated metalwork creates complex forms for components such as the bezel and the front button guard with impressive precision.

In addition, the case also features cylindrical stainless-steel components to guard the buttons, as well as gaskets on the button shafts and a screw-lock crown to prevent the intrusion of mud and dust. Also, the bottom and sides of the module incorporate αGEL to ensure vibration resistance.

Triple Sensor

Measures compass bearing, altitude/barometric pressure, and temperature. The seconds hand indicates north, while the indicator hand shows the recorded direction (bearing memory) and the direction to a point recorded in the app from the watch and/or a point manually set on the map within the app (Location Indicator).* These handy features help with checking the direction of a desired destination.

Solar-powered timekeeping with radio control and Bluetooth® connectivity

Smartphone Link and radio-wave time calibration deliver automatic time adjustment. Solar-power charging ensures stable operation of watch functions.

Super Illuminator

High-brightness full-auto double LED light improves watch readability in the dark.

Bio-based resin

Key resin components used in the bezel, case, and band are made with bio-based resin, a material expected to help reduce environmental impact.

Sapphire crystal

Scratch-resistant, highly transparent, and treated with anti-reflective coating to deliver excellent clarity and readability.
