The Casio G-SHOCK MUDMASTER watch series is designed for harsh land environments, and the new GG-B100 features an all-new Carbon Core Guard structure that employs carbon-fibre reinforced materials in the case.
The MUDMASTER is a part of the Master of G series designed for use in the most extreme conditions, with a dust- and mud-resistant structure that can withstand harsh land environments.
The newly developed Carbon Core Guard structure employs lightweight and rigid carbon-fibre reinforced materials in the case. The bezel also uses carbon for increased toughness. This new dust- and mud-resistant structure employs a filter inserted between the case and buttons to keep dirt out, ensuring a good seal without using metal button pipes.
The Casio G-SHOCK MUDMASTER GG-B100 is equipped with features that support land missions by linking the sensors to a dedicated app. The watch has quad sensor: the four sensors detect compass bearing, measure atmospheric pressure/altitude, and gauge temperature, and the accelerometer counts steps.
In addition to tracking changes in the natural environment, the watch can be linked with the dedicated app to easily grasp details of the activity history, such as calculating the calories burned from the ascent/descent based on the altitude and step count data.
The watch automatically adjusts the time via a paired smartphone, and a mission log function automatically records a track to the dedicated app based on altitude data from the watch and GPS data from the smartphone. A location indicator function displays the compass bearing direction and distance to a user-designated destination.
Main Features of Casio G-SHOCK MUDMASTER GG-B100
Carbon Core Guard structure and shock-resistant buttons
Casio has developed a new shock-resistant structure featuring a carbon composite case to protect the module. The new case also facilitated the development of a new button structure, which no longer requires exterior button guards.
A filter is inserted between the case and buttons to keep dirt out, ensuring a good seal without using conventional metal button pipes.
Dual-layer case back
The case back features a dual-layer construction employing stainless steel for a tight seal and glass fibre-reinforced resin for superior impact resistance. The design is inspired by the portable tanks carried by off-road vehicles that travel over rough roads.
Bezel with inserted carbon sheet
The bezel has been strengthened with a three-layer construction featuring a carbon fibre sheet inserted in the fine resin. The uppermost fine resin layer is transparent to show the carbon composite material below.
Quad sensor to easily track changes in the natural environment and grasp the activity history
The watch is equipped with quad sensor for compass bearing, barometric pressure/altitude, temperature, and an accelerometer for counting steps. The calories burned are calculated from the ascent/descent based on the altitude and step count data, and the activity history can be recorded to the dedicated app.
Mission log function
Automatically records a track to the dedicated app based on altitude data from the watch and GPS data from the smartphone. Manual operation also enables the user to acquire an altitude point and plot it on a map.
Location indicator function
Displays the compass bearing direction and distance to a user-designated destination. The compass bearing is indicated by the seconds hand and the distance indicated on the LCD display.
Customizable Mode button
The user can customize the functions to display when the Mode button is pressed, so that only essential functions are displayed or to change the order in which the functions are displayed.
