The Best G Shock Watch Ever?

You may remember a while ago in my Best Tactical Watches post how I raved about the G Shock Rangeman Master of G watch.​

I may have said something to the effect of:​

“Altimeter, barometer, thermometer, digital compass, atomic clock, solar powered, and tougher than nails made out of adamantium, coated in unicorn tears, and blessed by the pope. This G-Shock is so manly, I think I just got pregnant writing this review.​”

Anyways, apparently someone actually reads these things because I got one for my birthday a few months later!

Now that I’ve had it for a while, I figured I’d share my experience with the GW-9400-3CR in this G Shock Rangeman review.

AWGM100B-1ACR G Shock

I’ve owned a few G-Shock watches in my day, starting back in the 90’s.

I had the GA100SD-8A when it first came out (I still really like that it’s analog too) ​and I still have one of the original Mudman watches, the GW9000A-1, lying in a box somewhere.

So do I think that the Rangeman is the best G-Shock watch out there?

Hell yeah, I do!

Of course, everyone’s needs and tastes are different.

If you’re into diving, the Frogman​ might be more your style.

If you want something classier (and cheaper), but without all the sensors, I think the AWGM100B-1ACR looks outstanding.

But for the purposes of prepping and survival, I think the Rangeman GW-9400 is the definite winner.

Is the G Shock Rangeman for You?

While the Rangeman may be the best G Shock watch on the market, it doesn’t mean it’s the best choice for everyone.

Don’t know if it’s right for you? Just take our little test and see which side you fall on:​

It’s For You

  • You enjoy the outdoors
  • You need a watch that can take some abuse
  • You like knowing things like your current altitude, the exact minute the sun will set, or exactly which way North is
  • You own at least one article of camo clothing

It’s Not for You

  • You have bad eyesight
  • You don’t ever leave your house
  • You don’t know what a barometer is
  • You’ve never spent more than $100 for a watch

G Shock Rangeman Watch Features


Before the days of weathermen and weather apps, we had to figure out ourselves if it was going to rain. One thing we realized is that when the air pressure dropped, a storm was likely on its way.

Having a barometer on your wrist means that you’re much less likely to get caught in the rain when you’re out hiking or whatever it is you people do outside.​

So far, the measurements have been extremely accurate, from what I can tell.

I no longer have to check my achey knees to tell if there’s a storm a-brewin’​.


If you’re into hiking, climbing, mountain biking, or skiing, you’ll definitely get more use out of this feature than I do. Especially if you like competing to see who can go higher.

I live in one of the flattest states in America so my readings are usually within 50 feet of sea level.

However, altimeters can be extremely useful for survival as well.

gshock rangeman GW 9400 1CR review

Combined with a compass, you can use your altimeter to navigate through hilly or mountainous terrain​.


Sure, you can use your watch to navigate but it’s much easier when your watch has a digital compass built in.

What I like about the Rangeman’s compass is that it doesn’t just tell you North, Northeast, etc. It actually gives you the degrees so you can eliminate the guess work.


I’ll be straight with you guys, the only reason I ever check a thermometer is to complain about how hot or cold it is.

The only reason most of us ask what the temperature is outside is to figure out what to wear.

However, I can definitely think of a few scenarios where knowing the exact temperature could be helpful to survival.

For instance, if it’s only 38 degrees (Fahrenheit), you probably don’t have to worry about your water freezing over.

The problem I have with the Rangeman watch is that I have to take the watch off to get an accurate reading.

Because I’m just so darn hot and sexy that being that close to me will obviously skew the results.


If you hadn’t noticed from the pictures, the G-Shock Rangeman has a negative display, meaning it’s light text on a black background vs. dark text on a light background.

The reasoning behind this is that there will be less light to give away your position if you happen to find yourself in a covert situation.

The fact is that if they were really worried about the small amount of light or reflection that a positive display would give off, they wouldn’t have used stainless steel screws and clasps, bright​ yellow lettering, or a crystal without a matte finish.

Let’s just be honest. It’s got a negative display because it looks cool.​

See what you think of the negative display yourself here.

Time Keeping

The Rangeman performs pretty well at its original job too; being a watch.g shock rangeman tactical watch

There are 31 timezones built in so you never have to guess or do math, 5 daily alarms in case you REALLY have trouble waking up in the morning, a stopwatch, a countdown timer, and I’m sure a bunch of other features I haven’t found yet.

All of these functions can be saved (I think there are 40 or so memory slots) so you always remember exactly how long Grandpa’s story about ‘Nam lasts.​

Plus, the GW-9400 is atomic which means that you’ll never have to set your watch again, it just does it automagically!​

Sunrise/Sunset Data

This is another feature that I don’t get enough use out of in my every day, posh, comfy lifestyle though I’m sure it would be invaluable out in the woods.

The Rangeman GW-9400 comes loaded with every sunset and sunrise (not in that order) for every latitude/longitude coordinates until something like 2099.

Can you imagine if the Mayans or Druids had that? They would have saved so much time!​


Of course, one of the best things about the G-Shock Rangeman watch is that it can take a beating.

Not just a beating but a tsunami, a dust storm, and an earthquake too.

The GW-9400 is water resistant (to 200m), mud resistant (case and buttons are sealed to keep dirt, mud, debris out), shock resistant, and quite possibly kid resistant. Though the last one is still being studied.

It can also take temperatures down to 14 F degrees (-10 C)​. I don’t think I can even take that kind of cold.

Solar Powered

I can’t tell you how many watches I own that are just sitting on a shelf because the battery has died and I’m too lazy to go to the jeweler to get them replaced. So solar powered watches are a big plus to me.

According to Casio, the G-Shock Rangeman can last up to 7 months without any light.

What I Liked About the Rangeman GW 9400

It’s Badass

Just wearing this thing makes me feel like a member of Seal Team 6.

I keep waiting to receive orders from the pentagon about my next mission.​

But seriously, it really does look awesome. Be prepared to receive a lot of compliments from a lot of burly guys.

It’s Made Well

I’ve had my share of watches that looked great from afar but felt like they came out of a Crackerjack box when you actually held them.

The Casio Rangeman isn’t like that.

It’s not “heavy” but it definitely feels solid. Nothing feels cheap or “chinsy”. I’d say it weighs about the same as my old Fossil watch so there isn’t an issue with weight.

What I really like is the attention to detail that went into this watch.

For example, on the end of the strap is a raised section with some knurling or whatever you’d call it. This little bit keeps the strap from coming out of the keeper and flapping about all willy-nilly.

Also, all of the buttons feel solid when you press them. I’ve owned plenty of watches with buttons but they never felt right when I pushed them. I thought it was just a watch thing but Casio proves that they can be done right.

For my military folks, I’d like to point out that it’s easy to press these buttons while wearing gloves. I double checked with my Mechanix gloves and I had no problem.

It’s Got a Ton of Features​

I won’t bore you by listing off all of the functions and features that the G Shock Rangeman watch has, I think you get the point by now. If you’re interested, here’s a full list.

What’s important to me is that I’ve got this amazing weather station on my wrist, ready at the touch of a button (or in 10-15 minutes after I take it off my wrist if we’re talking about the thermometer).

And unlike my phone, the device I used to get all of my meteorological data from, I don’t have to worry about this watch getting wet or dirty or bumped around. ​

What I Didn’t Like About the Rangeman GW 9400

The Display

Yeah, yeah, I read all the reviews and heard all the complaints about how hard the negative display is to read in less than optimal lighting. And I bought it anyway.

And I’ll be honest, it’s not the easiest screen to read, even with the backlight.​

But that isn’t even my issue.

The problem is that I’ve gotten so used to my touch screen technology that trying to read all the little indicators and text makes my eyes hurt.

There is so much going on in such a small area that it gets overwhelming.

“At a glance” will never be used to describe how I get information from my Rangeman.

More like, “at a squint, and then a couple of button presses, and then some more squinting and tilting my wrist.”

Rangeman GW-9400-1CR alternative

And if you think the negative display might be an issue for you, I’d really recommend getting something else. I mean what’s the point of all these cool features if you can’t see or use any of them?

Check out the Rangeman GW-9400-1CR instead. It’s the same watch in black without the negative display.

The Learning Curve

This goes along with my gripe about the display.

I’m just so spoiled with the simple, intuitive user interfaces of today (cellphones, tablets, etc) that having to learn how to navigate with actual buttons is cumbersome.

The Rangeman watch has so many incredible features and abilities but the price that comes at is having to cycle through them all to get to the one you want.

Now I’ve got to remember where in line each function is and how to set an alarm and how to change my time zone and how to yada yada yada.

Just imagine you had to scroll through each one of your apps on your phone every time you wanted to access one.

See my point?​

Just saying that it may take you a week or so to get it all down.​

The Thermometer

Look, I’m not a scientist.

Or an engineer.

Or a doctor.

…Where was I going with this…

Oh yeah.​

I have no idea how to make a thermometer that you wear on your wrist totally ignore your body’s heat and only measure the atmosphere temperature.

But I do know that by the time I take off my watch and leave it somewhere away from the sweat lodge that is my body for 10-15 minutes, I don’t care what the temperature is anymore.

I know that if I was in a more life-or-death survival situation, knowing the temperature could prove useful.

But while the satellites are still spinning and the S hasn’t H the F yet, it’s much easier for me to just look it up on my phone.

My Opinion: Buy

I flipping love this watch and for all the features you get, I think it’s a really good price.

However, if you think the display might be an issue, I’d advise not getting this one. Check out the GW-9400-1CR instead.

Rangeman not your thing? Here are some good alternatives:

  1. Now that’s a review. Well done. I want to buy one but I know I won’t be able to read the time or the sensor functions without pulling out my readers. The negative display does look cool, though. Hell, I can barely read my Frogman without optimum lighting and it’s a positive display.

    • Glad you liked it! That means a lot to us.

      If you like the Rangeman, check out the Mudman (under Alternatives at the bottom of the post) or the GW-9400-1CR. They both have positive displays that might work better for you. The Suunto Core (also in Alternatives) has a bigger display that is MUCH easier to read. I have trouble reading a lot of the info on the Rangeman too without squinting because they crammed so much data onto it.

      Hope that helps!

    • There are many versions of this watch and most of them don’t have a negative display. There’s the black version of this that has all the same functions but different colours and has a normal display, as with most of the special editions, which I would love to have if they weren’t so bloody expensive. So if your only gripe is the negative display, get the other versions.

  2. Really, this is the best review I found online of this watch. Very honest and humorous at the same time. Congratulations!
    I have been considering buying this watch and after your review I just decided to do it. Thank you a lot!

  3. It’s really a great review. I ordered Rangeman today and was looking for a good and honest review and your’s is spot on 🙂
    Thank you

  4. Speaking as a survival minded former infantry Marine and law enforcement veteran…it’s the best watch I’ve ever owned. I shelved a Luminox in favor of the Rangeman.
    I got the positive display model, and then ordered the OD green bezel cover and strap, so I have a sort of hybrid Rangeman. Easy to read, easy to blend in the forest.

    Your review is great, and I appreciate the humor as well.

  5. way for reviewing the rangeman.. i just bought it yesterday.. after confused between rangeman gw9400 and mudmaster gwg1000.. i decided to buy the rangeman
