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.
