Introducing a new basic G-SHOCK black MUDMASTER model for the MASTER OF G Series watches with special functions for use under extreme conditions on land. The extreme black and minimal coloring of this model helps to ensure that vital information is clear and easy to read, even under the harsh conditions encountered by rescue teams and others who work in extreme environments.

Atomic Timekeeping
Shows accurate time by receiving radio signals of standard time information. JJY= Corresponds to both of Japanese standard waves JJY (40kHZ/60kHZ); WWVB= Corresponds to the USA standard wave WWVB (60kHz); MSF/DCF77= Corresponds to UK and Germany standard waves MSF/DCF77 (60kHz/77.5kHz); BPC= Corresponds to Chinese standard wave BPC (68.5kHz)
-
Solar Power
A solar cell provides power for operation
-
Auto-Hand Location
Using an LED, the positions of the hour, minute and second hands are checked at the 55'00" of every hour to ensure correct hand positioning. If the hand time does not coincide with the counter within the IC, the movement corrects the hand position automatically
-
LED Light (Full Auto Double Illuminator)
Separate lighting for the digital and analog portions of the face for easy reading. Illumination is automatically disabled when surrounding light is sufficient and enabled under dim or dark conditions
-
Compass
A built-in direction sensor detects magnetic north
-
Altitude Measurement
A built-in pressure sensor measures barometric pressure, which is converted to relative altitude
-
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 (R29)
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 100HR)
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
-
Vibration
Resistant
-
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
-
Sapphire Glass
Glass is made using artificial sapphires with scratch-resistant hardness second only to diamonds and high transparency
