Size Chart

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.

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.

* Image is included for illustrative purposes.

Sapphire crystal

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