Casio Rangeman GW-9400 Review & Complete Guide

One thing is certain, and that is that there is a G-Shock watch for everyone.

The Casio G-Shock is one of the most popular watches in the world. The good news is that over the years, Casio has consistently developed new models in order to cater to its audience.

The G-Shock range is known for consisting of watches that are well-built, robust, and extremely tough. And all of them are. But depending on which model you opt for, they offer different things, mainly in terms of functions, but also in terms of different levels of durability.

The Casio Rangeman GW-9400 is a watch that ends up at the top in terms of toughness and functionality. This watch is packed with functions, has an even sportier design than many others, and is built to last.

It is easy to see why this model is so immensely popular. It carries the G-Shock DNA that people have come to love and expect, it offers great value for money, and it is packed with useful functions. This is a watch that is so tough that it can handle virtually any condition and be a solid partner for many years to come.

Without further ado, let’s look closer at and review the Casio Rangeman GW-9400.

Case

Like most G-Shocks, the watch is presented with a sturdy and robust black resin case. The case is thick and creates strong protection against shocks, making it extremely durable.

Firstly, the resin case construction is raised above the screen in order to keep it protected. On top of the bezel, you will also find information about what each pusher does so you can easily know which button does what. The Rangeman has one large pusher at 3 o’clock with which you cycle through the sensor function modes. The other pushbuttons are used for regular functions such as modes, adjusting, and reverse.

In terms of profile and size, the Rangeman GW-9400 is rather big. But at the same time, its large size goes well with its purpose. The watch has a diameter of 53.5mm and a length of 55.5mm. The thickness measures 18.2mm. With that said, you either need to enjoy wearing large watches or have a large wrist to pull this off, but this isn’t anything new. In fact, it is what we expect a G-Shock to be.

But worth having in mind is that despite its large size, this watch wears surprisingly comfortably thanks to its lightweight of only 93 grams. In addition, its integrated resin strap allows it to ”hug” the wrist and thus sit better on the wrist. The top of the case is put together with the back of the case using 4 screws in each corner which adds to its sporty look.

Speaking of the strap, the black resin strap is just as tough as the rest of the watch. It is water-resistant, scratch-resistant, and very durable.

The Rangeman GW-9400 has a water resistance of 200 meters/660 feet which means you can go swimming and diving without any issues.

For this type of watch, it is really self-explanatory, but the Rangeman GW-9400 is made to take a beating and will hold up extremely well to virtually any situation you subject it to. Water, dirt, mud, sand, or anything in between. Just give it a good rinse afterward and it is as good as new.

Screen

The watch is a full digital watch and therefore does not have an analog timekeeping display. Instead, the information and time is presented in the form of screens. The screen is divided into different sections to make it easier to read all of the information that is presented. Naturally, the time is presented with the largest font so a quick glance at the wrist is all it takes.

Functions

First off, the Casio Rangeman GW-9400 is the first Rangeman G-Shock to incorporate a so-called ABC sensor technology, which, in regular English means that it uses triple sensor technology, meaning that it has an Altimeter, Barometer, and compass. These are all three features that can come in handy whether you are out in the field, skiing, or doing other demanding activities. In addition to these three, the watch is also equipped with a thermometer.

The watch uses the version 3 module which has been made smaller and more effective. It uses less power and is able to be more precise.

The sensors are certainly the highlight of this watch, but this certainly isn’t everything this watch has to offer. In fact, it has so many functions that it will be easier to list them at the end of the article, but the most important ones to know of are the following: The watch is equipped with a chronograph stopwatch that measures up to about 1000 hours.

It is equipped with a sunrise and sunset function, and it can also give you information about the sunrise/sunset times for future or past dates. This is enabled by using your current timezone as well as the latitude and the current date.

For accuracy, the Casio Rangeman is solar-powered which means it uses solar and ambient light to charge the battery. This eliminates the need for replacing the battery which is really practical and also good for the environment.

The watch has an atomic clock signal radio which ensures perfect accuracy at all times.
