Whether desert, jungle, snowy mountain terrain or wilderness,
every outdoor environment becomes a field of activity.
RANGEMAN is built to achieve the ultimate toughness that G-SHOCK pursues, with high specifications for shock, dust/mud and water resistance,
and advanced survival features ranging from GPS signal reception
to Triple Sensor and solar operation of every function.
Bluetooth® communication has been added to enable linking with smartphones. G-SHOCK continues its relentless challenge
as the leader in acquiring the toughness and functionality to operate at extreme limits. A “survival-tough” new RANGEMAN is born.


Wearable Functions for Survival under Arduous Conditions

GPS Navigation:

The built-in GPS acquires positioning information from GPS satellites and displays the positions of the current location and destination
in real time. Besides displaying the trajectory of your travels and a record of key geographical points to assist on your return, it provides a route map with the start point and destination reversed.

Solar-assisted Recharging:

A solar-charging function is available to support the wireless-charging system. This makes long-time GPS operation possible in environments with no power supply, contributing to a high-stamina performance you can count on in extreme environments.

– Approx. 33 hours operation without a power supply after a full charge (approx. 5 hours with wireless charging)
– Operation extended to approx. 48 hours with solar charging in sunny conditions (50,000 lx)

G-SHOCK Connected Smartphone App

A Smartphone app is available for easy setting of various watch functions, including GPS Navigation and log management.

– Route Setting
Register the start point, destination and
key points along the way on the map to
create a GPS Navigational route map.
– GPS Log Function
Save the trajectory of your movements
on the app. You can then review such
factors as your route, altitude changes
and information on points along the
way on a timeline or 3D graphic
• Triple Sensor [Altimeter / Compass / Barometer / Thermometer]
• Sunrise & Sunset time / Tide graph / Moon data
• 2-way Time Sync [GPS Controlled/Smartphone link functions]

Pursuit of the Strength to Overcome Harsh Environments

Mud-resistant Structure:

Gaskets are fitted around the buttons and in the button shafts, and silicon is installed at the base of the crown. Air-tightness is increased to prevent mud from entering the case without compromising operability.

Fine Resin Insert Bumper:

A newly developed, two-color molded resin bumper with a high-strength fine resin insert is installed. In addition to preventing damage from impacts, it protects the case while minimizing case thickness.

GPS Antenna Bezel:
The stainless-steel bezel incorporates a GPS antenna function. Stable reception is achieved by thus arranging the ring-form antenna outside the case.

Ceramic Case Back:
A ceramic case back that supports wireless charging and high-sensitivity GPS signal reception has been adopted. The 2.0 mm thick ceramic material satisfies G-SHOCK’s strict shock-resistance and 200 meter water-resistance specifications.

• MIP (Memory In Pixel) High contrast LCD
• Carbon-fiber insert band •Sapphire Crystal
• Low-temperature resistant (-4°F/-20°C)


Links with a smartphone for more accurate timekeeping and access to a host of mobile link functions.

Shock-resistant construction protects against impact and vibration


CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power.



Connection with a phone requires installation of the G-SHOCK CONNECTED App on the phone.

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

  • Temperature Measurement

    A built-in temperature sensor measures the temperature

  • Low Temperature Resistant -10°C/14°F or -20°C/-4°F (-20°C/-4°F)

    The timekeeping module is designed for operation at very low temperatures. The value indicates the lowest temperature at which the module will operate. *-10°C/14°F or -20°C/-4°F do not apply to the direction sensor

  • Moon Data (with Moon age indicator)

    Displays approximate Moon phase based on date and time differentials. AGE = Moon age indicator (Moon age error: within ±1 day)

  • Tide Graph

    Graphically displays tides based on lunar periodicity and lunitidal interval time

  • World Time (R39)

    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

    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
