G-SHOCK makes a lot of heavy-duty watches, including a variety of watches tailored for air and land. There are many options to sift through, which is why we’re focused on the G-SHOCK Master of G Land category for you land-based adventurers out there.
The G-SHOCK Master of G Land Series is a collection of rugged G-SHOCK watches that can withstand extreme conditions with a shock-resistant build, 200m water resistance, and yes, even mud resistance.
Within the series are more specialized RANGEMAN and MUDMASTER watches that add to the performance features like GPS, altimeters, digital compasses, solar charging, and smartphone connectivity.
G-SHOCK watches are known for their rugged, seemingly overbuilt looks, with protective bezels and button guards. The big buttons aren’t subtle either, and that’s the point. You should be able to get to the desired function easily and deliberately, even with gloves on. And then there’s the display, which has a rather intuitive layout that displays different measurements while keeping a dedicated spot for the time.
Essentially, it’s the mix of durability, precision sensors, and ease of use that makes the Master of G Land Series popular among outdoor workers and adventurers.
RANGEMAN: GW9400-1
The GW9400 RANGEMAN line is part of the Master of G series, G-SHOCK’s line of tough and rugged digital timepieces. It’s ready to tackle the most grueling conditions.
RANGEMAN’s Triple Sensor uses three small sensors to track altitude, barometric pressure, temperature, and direction. It is made to fit the demanding activities of rangers, rescue crews, and anyone else whose profession or hobbies require performance in the field.
Beyond the G-SHOCK toughness and durability, the GW9400-1 watch provides one-touch time recording and elapsed time measurement — a testament to the RANGEMAN’s physical design and ease of use.
Its cylindrical buttons are impact-resistant, while the frequently used sensor button (center right) has a metal cover that protects it from impact and keeps out grit and grime. One press of that button takes you directly to a sensor screen where each sensor mode has a dedicated audible tone. That means you can scroll modes by ear while keeping your eyes up ahead.
The watch can display time in 12- and 24-hour formats and track world time zones. There are also five daily alarms, and it can display sunrise and sunset times for a specific date. It uses Multiband 6 radio wave reception to automatically update time, date, and daylight saving time.
MUDMASTER: GGB100-1A
Part of the G-SHOCK MUDMASTER Series, the GGB100-1A watch is designed for use in extreme environments where the landscape is rife with dirt, debris, or mud. For instance, a high-rigidity carbon fiber-reinforced resin case (aka Carbon Core Guard) protects the structural integrity of the watch while bolstering its overall airtightness and shock resistance.
Furthermore, this watch specializes in keeping out mud and other grime, with a stainless steel back panel covered with a shock-resistant fine resin embedded with glass fibers.
The GGB100 helps you navigate in the field with a compass, altimeter/barometer, temperature reader, and pedometer. Through Bluetooth, the watch connects to the CASIO WATCHES app to adjust the time and transfer data recorded along your route into a Mission Log.
Other watch features include world time, sunrise and sunset times, and five daily alarms. It connects to a smartphone via Bluetooth to automatically adjust the time, date, and DST settings.
Even if you’re not running a Tough Mudder, this watch makes sense for those who often return from a run, hike, or hunt with a “dirt tan” around their wrist.
RANGEMAN: GPRH1000-1
The other Master of G RANGEMAN, the GPRH1000-1 is another watch ready for the most extreme climates and environments. It expands upon the base RANGEMAN with mud and dirt resistance by way of gasket fittings and steel shock panels on the sides to protect its buttons.
Notice the overbuilt bezel (made from a bio-based resin), which protects the watch and especially the watch face from more than superficial impacts. It also has solar-assisted charging.
The GPRH1000-1 includes several tracking features like GPS, heart rate monitor, altimeter/barometer, thermometer, accelerometer, gyroscope, tracking biometric and environmental data, too.
Moreover, you can track a route, conditions, and performance metrics while trekking, running, swimming, and other efforts on the watch and then share that data with Strava and Apple Health apps. It tracks your biggest efforts alongside your regular workouts. After all, aren’t big adventures what all that training is for?
Furthermore, the optical heart rate sensor measures blood flow and lets you check blood oxygen levels, which can be a useful way to check in on how you are acclimating to high altitudes.
Other GPRH1000-1 RANGEMAN features include world time, stopwatch, countdown timer, tide graph, four daily alarms (one with snooze), moon phase and sunrise/sunset data, and a battery level indicator.
With mud and dirt resistance, G-SHOCK shock resistance, and 200m water resistance, the RANGEMAN: GPRH1000-1 watch accepts the challenge of the roughest land conditions.
G-SHOCK Master of G Land Series
As you can see, these watches represent different levels of tracking and weather resistance. Even though the RANGEMAN, MUDMASTER, and MUDMAN are part of the Master of G land category, they are water-resistant down to 200 m and use different protective designs to withstand a fair amount of abuse — including in the water.
Picking the one right for you will depend on which attributes mean the most. The RANGEMAN: GW9400-1 is a great intro to the Master of G series, with all the protection of a G-SHOCK combined with ample functions that track environmental conditions.
For those who work in the muck, the MUDMASTER: GGB100-1A wards off the elements to protect the watch while providing plenty of functions in the field. Lastly, the trekker and fitness fiend who trains so they can accomplish more on big days may reach for the RANGEMAN: GPRH1000-1.
