GGB100BA-1A
The British Army X G-SHOCK MUDMASTER was built to withstand the harshest land environments and features an updated Carbon Core Guard Structure and triple-layered carbon-insert bezel, providing durability in a lightweight case. The special-edition MUDMASTER features a camouflage design inspired by the Army’s own Multi Terrain Pattern. Furthermore, the model sports an all-black dial, specifically used by the British Army, so as not to attract undue attention when worn on operations.
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-fiber 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-fiber 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 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. With its new construction and advanced features, the GG-B100 is a G-SHOCK ready to support the toughest missions in harsh conditions.
This new shock resistant structure protects modules with a carbon fiber reinforced resin case.
Highly airtight carbon case and filter protects against intrusion of mud.
A triple layered structure with a carbon fiber sheet inserted between fine resin.
– Mission Log function
The altitude measured by the watch and the course obtained from a smartphone’s GPS are automatically recorded to an app. An altitude point can be manually acquired and plotted on the map.
– Location Indicator
Record your current location in an app. Display shows your recorded destination by the second hand, and the distance on the LCD.
– Calorie calculator
– Mode/display switching customization
– Automatic time adjustment*
– World Time for over 300 cities*
– Phone Finder
* Updating of internal data according to the latest time zone/ daylight saving time information
Supported Phone Models (As of Jan 2019)
* Bluetooth installed smartphone only.
A light emitting diode is used to illuminate the face/display. Super Illuminator uses high-brightness LED for easier reading
A built-in acceleration sensor detects arm movement, when walking, which is used to count the number of steps taken. With some models, measured data is also used to calculate energy consumption
A built-in direction sensor detects magnetic north
A built-in pressure sensor measures barometric pressure, which is shown on the display
A built-in temperature sensor measures the temperature
Displays the current time in major cities and specific areas around the world. R: Current time in major cities around the world. Values indicate number of cities/areas
The daily alarm sounds each day at the time you set. The value indicates how many alarms are available. The hourly time signal causes the watch to beep every hour on the hour
Each time you stop the alarm, it sounds again after a few minutes
Accurate measurement of elapsed time with the touch of a button. The fraction indicates the unit of measurement, while the time figure indicates the maximum time measurement
Counts down from a start time specified by you. The value indicates the number of timers available, while the time figure indicates the maximum starting time. “REPEAT” indicates Auto Repeat, which automatically restarts timing at the end of each countdown
Allowances are made automatically for months of different lengths, including leap year
Times can be displayed in either 12-hour or 24-hour format
The tone that sounds to signal a mode change or other operation can be turned on and off
Indicator shows the current battery level
Shock-resistant construction protects against impact and vibration
Dirt and mud-resistant construction keeps mud and dirt from getting into the watch
A luminous coating provides long-term illumination in the dark after only short exposure to light
The “BAR” value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked “200m” have the same water resistance as 20 BAR watches
Hard glass resists scratching
