Casio GW9400 Rangeman Watch Review: Best G-Shock Today?

Source : ABTW

I love to review new Casio G-Shock watches and today I’d like to share with you the excellent GW9400 Rangeman. Clearly I don’t cover each new G-Shock model, but I make it a point to notice the best new pieces from Casio that continue to offer more of what we love in what is arguably the world’s most useful collection of timepieces. The G-Shock recently celebrated its 30th birthday in 2013 and has a life of its own among Japanese Casio’s other watch families. A brand unto itself, the G-Shock is an item that has the remarkable ability to appeal to watch lovers of all ages, budgets, and tastes.

In my opinion the Casio G-Shock GW9400 Rangeman is one of the most important Casio G-Shock models in a while, and is possibly the best Casio G-Shock watch available today. From a durability, functionality, and style perspective, this is one hard watch to beat. Will they get better in the future? Probably, but a modest investment will get you a fantastic “do anything” watch for at least several more years. An easy way to understand a cornerstone feature of the Rangeman is that it is the first Casio G-Shock that includes the full stack of “ABC” sensor technology. “ABC” is an acronym often used to describe Casio’s “Triple Sensor” technology that for many years you’d only find available in its Pro Trek (previously Pathfinder) collection of watches. Triple Sensor meant that the watch contained an Altimeter, Barometer, and Compass. It also happens to include a thermometer; which never seems to get included in “triple” sensor, but that is included as well.

For several years Casio had been experimenting with the inclusion of this sensor technology into Casio G-Shock watches. In fact, the GW9200 Rangeman is a follow-up to the GW9300 Mudman, and the GW9200 Riseman before it. Those previous models contained some, but not all of the Triple Sensor technology. The Rangeman has them all, and in a satisfying way that allows them to live within the the durable G-Shock shell and still be easy to operate.

A logical question is how the the GW9400 and current Casio Pro Trek models compare to one another. That is a really good question and there are of course differences. Having said that, more good news is that, from what I can tell, Casio included the Version 3 Triple Sensor module into the GW9400 Casio G-Shock watch. Released in 2013 as well, the Triple Sensor Version 3 module was discussed a bit more right here. In fact, the smaller size of the new module is probably what makes it possible for Casio to include the full ABC set of features into a G-Shock watch. In a nutshell, the version 3 module is smaller, uses less power, is faster, and is more precise than previous generation sensors. Watches such as the Casio Pro Trek PRW3000 and the lower-priced PRG270 (also both new for 2013) contain the version 3 module and so does the GW9400.

Honestly, if you want a triple sensor watch from Casio and don’t already have one, I recommend one of those three models from 2013 and onward. They offer a noticeable improvement over previous models and set the standard moving forward. Casio used the version 2 module for a full decade, so we expect to see at least a solid five years of use out of the version 3 module.

Casio Pro Trek watches use dedicated pushers on the right side of the case for each of the three sensor functions (they display the temperature when you view the barometer information). Pro Trek models also have a larger LCD display, which isn’t broken up into a few sections as Casio typically does with G-Shock models. That means Pro Trek pieces offer a slight edge in usability and legibility. The Rangeman on the other hand, has one large pusher at the 3 o’clock position which is used to cycle through the various ABC function modes. While the displays are different, functionality is the same.

Casio can’t after all hand over all of the benefits of a Pro Trek to a G-Shock, so there are advantages to the Pro Trek depending on the wearer. What is oddly ironic for the first time, is that most modern Pro Treks are slightly smaller than a G-Shock. That means that we consider the Pro Trek PRW3000 (for example) to be a svelte, slim timepiece companion next to the bolder and masculine looks of the Casio G-Shock GW9400 Rangeman. I have both so I don’t really prefer one over the other, and functionally they are very similar. I like the bold looks of the Rangeman more, but with its smaller size and more legible screen, I like the PRW3000 for things like exercise and sports, while the G-Shock is great for things like hiking, swimming, and otherwise adventuring.

In addition to the full set of ABC triple sensors, the GW9400 has a range of other features that you’ll find in most G-Shock watches. Nevertheless there are improvements and additions. Did you know that the chronograph (stopwatch) now measures up to about 1000 hours? The watch also contains a sunrise/sunset feature that I love and frequently find useful. The watch uses your current timezone location along with your latitude (that you can set manually), as well as the current date to know the precise sunrise and sunset time where you are. You can also travel back and forward in time with the push of a button to know the sunrise/sunset times for future or past dates. Without having to list the full range of features in the Casio G-Shock GW9400 Rangeman, I’ll just offer up Casio’s specs for the watch:

As you can see there is a lot this little gadget can do. It is also worth noting that the Rangeman uses solar (any light for that matter) charging for the battery, and it has a six band atomic clock signal radio. That means no battery changes and updated accuracy. Great, another watch you don’t need to ever worry about. Even though I primarily wear mechanical watches I find myself often taking a Casio along with my on travels as a backup or reference clock.

You really can beat up a G-Shock – and they clean up well. I’ve taken the Rangeman into dust, mud, ocean water, into bright sunlight, all while being active. The pictures I took for this review are of the watch after all of that. Yes, the watch isn’t infallible. You are still talking about a watch made of metal and plastic, but compared to most other timepieces on the planet these can put up with a lot more abuse. Considered a higher-end G-Shock. the GW9400 uses a good amount of metal. The case back is completely in steel, as is the strap buckle and loop for the excess strap. What is also great is that the pushers (large and easy to push) are metal. They have a great looking texture to them and are a pleasure to operate.

At about 53.5mm wide, the Rangeman wears comfortably, especially because it is so light – being about 93 grams. It is also water resistant to 200 meters and obviously very shock-resistant (that is the cornerstone of “G-Shock’s religion”). Also, there is a rare character design on the back of the watch. Casio does this from time to time and I find it amusing when they give a watch the added character of a figurine “Rangeman” mascot. The rear of the watch has a sort of electric feline wearing what looks to be a compass. I don’t know how much sense it makes but I like it.

Is the watch easy to live with? Well I grew up wearing G-Shock watches most of my life so I’d say so – and the Rangeman is no different. The digital display offers a range of information and the home screen is very useful. The upper right section can display either the day of the week or a graph showing changes in barometric pressure, and you also have calendar information and the time at a glance. The dial even features a power reserve indicator for the battery, which is nice to know from a quick look. The upper left circular quadrant has Casio’s typical “pie-chart” seconds counter. Though this is also used as the compass needle in compass mode.

There is no need for me to discuss everything from the watch’s five daily alarms or countdown timer. I assume that most people reading this review have had some experience with G-Shock watches, so they generally know the core set of functionality that Casio has offered in them for decades. It is true that we tend to take all of these features for granted. Having said that, after wearing digital watches from many other brands, I have to say that going back to using a G-Shock is like returning to an old friend. Sure quirks exist, but overall these watches offer a straightforward and mostly logical set of features – which are best offered in Japanese digital versus analog watches.

Casio produces a few versions of the G-Shock GW9400 Rangeman right now. It is entirely possible that new colors will pop up here and there. What is confusing is where each of the models is sold. While you can get all of them in Japan or online, different countries carry different models. Having said that, the version I reviewed is the “international model” that will be sold everywhere. So this piece in black with a standard LCD display is the Rangeman model GW-9400J-1JF. There is also the same version but with a negative (black) LCD screen and that is the GW-9400BJ-1JF. If you like military green then a cool version is the green with black screen Rangeman model GW-9400J-3JF. There is one more known model that is a Japanese exclusive limited edition meant for the 30th anniversary of the G-Shock. It is a yellow version of the Rangeman, and probably has a price premium. It is the Rangeman GW-9430EJ-9JR.

Some of you already know you want a Rangeman and probably others already have it. It also only been out in the US for several months at the time of this review but we’ve noticed that G-Shock fans are snapping them up. There is good reason for that. I’d like to discuss these watches in another context outside of outspoken G-Shock lovers. Is this a good watch for a luxury watch lover? I am going to say yes. As a watch snob who looks down on most quartz timepieces I always admire a G-Shock. No I don’t wear one all the time, but for me these are a must for any collection. They are not only the ultimate beater watch, but they look cool. For me the design takes inspiration from Transformers as much as it does Batman. These are the epitome of modern watches and make a case for themselves in terms of price, design, and functionality.

If you are a serious watch collector with $100,000 pieces there is no reason why you can’t also wear a G-Shock once in a while or while you are taking a hike. This is among the very budget watches (like a standard Swatch) that transcends luxury status and has appeal to everyone. Wearing a G-Shock is about being and feeling youthful more so than it is anything else. For me it is a reminder to get outside and do something, and if I want to do it wearing a yellow, black, white, purple, or orange watch (among more colors) I can do so with a G-Shock. The Rangeman GW94000 is the current best of breed (even though there are more expensive models out there) and it would be silly for us to do anything but recommend it for those who see a place for one in their lives.
