GGB-100-1B

MASTER OF G BLACK OUT This is the latest model from MASTER OF G, the G-SHOCK series of watches designed and engineered for use by those whose work takes them into extreme environments scattered with rubble, dirt, and debris.
The basic black coloring of this model further enhances the rough and tough look of the resin material and the MASTER OF G design. Base model is the MUDMASTER GG-B100, which uses carbon material that delivers a new level of shock resistance, and dust and mud resistance.
This tough new watch puts functions that support high level performance at your fingertips.

Main Functions

– 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

* App screens shown here may differ from actual screens, since the app is currently under development.

  • LED Light (Auto Super Illuminator)

    A light emitting diode is used to illuminate the face/display. Super Illuminator uses high-brightness LED for easier reading

  • Acceleration Measurement

    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

  • Compass

    A built-in direction sensor detects magnetic north

  • Barometric Pressure Measurement

    A built-in pressure sensor measures barometric pressure, which is shown on the display

  • Temperature Measurement

    A built-in temperature sensor measures the temperature

  • World Time (R48)

    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

  • Daily Alarm, Hourly Time Signal (5)

    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

  • Snooze Feature

    Each time you stop the alarm, it sounds again after a few minutes

  • Stopwatch (1/100 24HR)

    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

  • Timer (60 MIN)

    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

  • Full Auto-Calendar

    Allowances are made automatically for months of different lengths, including leap year

  • 12/24-Hour Timekeeping

    Times can be displayed in either 12-hour or 24-hour format

  • Operation Tone On/Off

    The tone that sounds to signal a mode change or other operation can be turned on and off

  • Battery Level Indicator

    Indicator shows the current battery level

  • Shock Resistant

    Shock-resistant construction protects against impact and vibration

  • Mud Resistant

    Dirt and mud-resistant construction keeps mud and dirt from getting into the watch

  • Neobrite

    A luminous coating provides long-term illumination in the dark after only short exposure to light

  • Water Resistant (20 BAR)

    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
