The G-Shock RANGEMAN Master or G-GW9400-3 is definitely a niche watch in today’s smartwatch world. Let me start by saying I put this watch through the gauntlet over the past three months, this watch has been with me on some hardcore downhill MTB rides, several triathlons, ice climbing, and a proper backpacking trip in Alaska. Also, as a quick note to give you a better idea of my impressions/judgments, I also currently own a Samsung Gear 2 and a Garmin 735XT.

I broke this review down into five categories, which will give you a good idea of where this watch fits into your collection.
1.Style. For a watch built for toughness it is a darn good looking watch. My first impression was it might look like a beast but it isn’t too big and I really do like the look of this watch. I will always choose comfort over style, especially with a piece of gear I need to depend on in the backcountry. Luckily, I don’t have to make any sacrifices with this watch. Casio did a great job making this watch look the part and still be stylish while packing in all the capabilities it has to offer. I especially like the look of the digital compass in the top left-hand corner, that little touch of gold in the face is a subtle accent of style in this rugged build.
2. Features. This is the real reason you’re going to spend the money on this watch: Casio packed this watch full of some very useful and important capabilities. Here are my top five functions on the watch since there are too many functions to cover in detail.
- Tough Solar Power: You will never need to charge or replace the battery with this watch! How awesome does that sound in today’s world of always looking for somewhere to plug in. Even if you were living in a cave this watch would still last you seven months on a full charge. Having the solar power really makes this watch stand out, especially in the smartwatch era that we are approaching. The last thing I would want is my watch to go dead if I was lost in the wilderness and it isn’t a worry with this watch.
- Triple Sensor (Altimeter, Barometer, and Thermometer): Super important features to have when you’re headed out on an “epic” in the backcountry. For me, knowing the temperature, altitude, and weather are deciding factors for going forward on a big objective and having that information to make the right decision can be priceless if not life saving in some situations. I found all three functions to work well in the backcountry, the thermometer, of course, got a more accurate reading when off my body.
- Shock/Mud/Water Resistant: Another strength of this watch is you can beat it up without worrying about it handling your adventure. I took a brutal fall on the downhill bike where I went over the handlebars and the watch didn’t even get a scratch but the rest of my body couldn’t say the same. I also grinded the face against a glacier while ice climbing and the same thing happened, I got some cuts but the watch was good. As for water resistance, I did a lot of open water swimming during triathlons and there was never any issues. I wore this watch when I knew my other watches would not be able to withstand the punishment I was going to be dishing out.
- Memory Capacity: To be honest, this is a function I didn’t get to dive very deep into but I could see it being a very useful tool on longer trips into the backcountry. Up to 40 records (shared storage with date/time, bearing, and barometric pressure/temperature records). The main reason I did not get too deep into this is because in today’s smartwatch world it is not as simple to use as I would like. It just doesn’t have the technical ecosystem that we’ve grown a custom to.
- Digital Compass: A pretty common feature in watches these days but the G-Shock RANGEMAN did a great job of making it clear and easy to use on this watch. It measures and displays direction as one of 16 points with a measuring range from 0 to 359 degrees and a graphic direction pointer with bidirectional calibration and magnetic declination correction. On my last backpacking trip we were off trail and route finding almost the entire time so having a spot on compass was invaluable.
3. Comfort: An important part of every watch and one this one does well. The watch fits great with a ton of length options on the band and it actually feels pretty light. For backpacking, I would rank this watch very high on the comfort level. For the day-to-day use I rank it as just OK. As I mentioned before it got through several triathlons but wasn’t the most comfortable watch I’ve worn for endurance sports. Although, this watch was not made for triathletes and belongs at home in the backcountry.
4. Durability: Another one of the key traits to this watch is it can just take a beating. On the durability side, I don’t know if there is anything I would change, it is a beast.
5. User Friendliness: Here is where the G-Shock RANGEMAN looses a lot of points. I know Casio did not build this watch to compete with all the smartwatches out right now so it’s probably a little unfair to put them in the same category. But with that said, if you are into everything being super intuitive like your smartphone then you might get a little frustrated when setting all the functions up with this watch.
The manual alone might cause some fear but to be fair it wasn’t terribly hard to get the necessary features dialed in.

Should You Buy This Watch? Yes, but only if you plan to be in the backcountry a lot. Sadly, I feel the G-Shock RANGEMAN is a bit outdated when it comes to the intuitive technology we’re accustomed to today. So if you’re looking for an everyday watch, I don’t think this watch is worth the money. For my own personal use, I am excited to have the Master of G-GW9400-3 in my collection but I think it is most likely going to be on the shelf and only come out on the big adventures because that is where this watch shines.
