Casio to Release G-SHOCK MUDMASTER with Carbon Core Guard Structure

New Constructure using carbon materials Delivers Toughness; Equipped with Triple Sensor and Accelerometerfor Land Missions in Harsh Environments.

Casio Computer Co., Ltd., announced today the latest addition to the MUDMASTER series of G-SHOCK brand shock-resistant watches. The MUDMASTER 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 and case back also use 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 GG-B100 is equipped with features that support land missions by linking the sensors to a dedicated app. The watch hasa triple sensor and an accelerometer: the three 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.

With its new construction and advanced features, the GG-B100 is a G-SHOCK ready to support the toughest missions in harsh conditions.

Main Features of the 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.

Mud-resistant structure

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 carbon 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 constructionfeaturing a carbon fibre sheet inserted in the fine resin. The uppermost fine resin layer is transparent toshow the carbon composite material below.

Quad sensors to easily track changes in the natural environment and grasp the activity history

The watch is equipped with quad sensors 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.
