The Casio Rangeman watch is a tricky product for me to review. Don't get me wrong: It's highly functional and robust, well-conceived, and most of what it does it does quite well. What makes this tricky is that the Rangeman poses a philosophical dilemma, for somebody like me who collects watches: Do I really need anything more than this? What is the appropriate criterion for judging a watch like this? I'm writing this review in part to try to answer those questions.So first off, I bought this watch with several specific use-cases in mind. I wanted a light-weight, shock-resistant watch for running with, and I also wanted it to be easy to read, and to have the ability to function as a stopwatch. I also wanted a "field watch" for hiking, kayaking, and other outdoor activities away from civilization -- hence no smart watch or fit-bit. I liked the idea of solar power, so as not to need to change the battery out for 10 or 15 years, at least. And finally, because I do have some other mechanical watches, I also wanted an "atomic watch," something that would always be synced and accurate and that I could use as a reference to set other time-pieces. So those are the reasons why I picked out the Rangeman to try.This was not my first experience with a Casio G-Shock, by the way. And my previous G-Shock was not a success -- I got a GX-56 "King," with the primary aim of using it to time myself during a mud-run obstacle course. Unfortunately, I bought one with a "reverse" LCD display -- i.e., where the numbers appear white on a black background, instead of the other way around. That turned out to make that watch difficult to read, even in bright sunlight. And I learned the hard way that if I can't easily read the face of a digital watch, then it's useless to me. Which added another demand to the use-case for my new Rangeman: it had to be very easy to read the time, regardless of the ambient lighting or the angle of my wrist.So here's the good news: It turns out that the Rangeman is quite good for all of my use-cases. It's easy to read, light-weight and good for running, good as a field watch, with excellent atomic time-keeping. If anything, I find myself using this watch for more situations than I expected to. On a recent business trip across country, for example, I kept the Rangeman with me, because it's world-time function made it easy to switch time zones, while still keeping track of time at home. Plus the basic home screen display, which shows the time, day, date and month (based on a perpetual calendar through the year 2100) is incredibly functional and useful. So yes: by comparison with most mechanical watches, the Rangeman is almost ridiculously functional, even just in terms of the basic display that you get without pushing any buttons at all. Did I mention that (in the U.S.) the Rangeman will automatically keep track of daylight savings time, and make the adjustment without you even having to think about it?So this led me to the existential question, do I really need any other watch, now that I have this one? After thinking about it for several weeks, I've concluded that the answer still is yes, at least for me. And the reason why goes to specialization: namely, a watch designed to do one thing can be tailored to that purpose, whereas a watch designed to do many things necessarily involves some compromise. And sometimes, I really do want the specialized watch. So for example, I have an inexpensive mechanical dive watch (similar price point to the Rangeman). My diver is a better watch for swimming than is the Rangeman. Even though the latter is supposed to be water resistant to 200m, I simply don't feel confident in this to the same degree that I do with my mechanical watch. (Look at the reviews on Amazon -- 19 out of 20 people love the Rangeman, but the remaining 1 out of 20 gets a lemon, often to do with faulty water resistance.) Likewise, my mechanical dive watch is actually better for sleeping with -- it has glow-in-the-dark lume on the hands, which means you can easily see the time with a glance even in a pitch-black room, or under the covers. The Rangeman can also light up in the dark, but you either have to push a button for this, or else set the watch so that it automatically lights up every time you move your wrist when in the dark -- and neither of those options is as good for sleeping with as is a traditional mechanical dive watch.Getting back to my recent trip across country: I sat next to another passenger who was wearing an expensive watch on the plane, I believe it was a Tag Heuer Carrera -- a racing-inspired sports watch on a leather-band, the kind of thing you might wear out for an evening with on the town with friends, when visiting Monte Carlo. By comparison, my Rangeman looked almost like a toy. Don't get me wrong -- I very much like the bulkiness and the tactical look of the Rangeman. But it's certainly not a watch that slides easily under a dress shirt cuff, or that fits in well at the office. Which is just another way of saying, as versatile as the Rangeman is, the design is optimized for some uses and settings, but not others. Camping? Yes. Covert ops? Yes. Going to your best friend's wedding? Probably not.In sum, I still give the Rangeman 5 stars. It is very well designed for what it is, and it does many things well. I've had it for a month, and I am enjoying it a lot. Even though it won't replace other watches for me, I certainly wouldn't give it up, now that I've experienced it. So there!

When I was a kid and G-shocks were new, I wanted one from the time I first saw one. After I got my first one, there was never a time when I didn’t have one on my wrist all through my school years, my construction years after school, then onto boot camp and nine years in the army. After the military I went on to law enforcement and the G-shock stayed with me. Unbelievably tough, the only excuse I ever had for buying a new one was just because I wanted a new model. They never failed.As I got into my late 40’s early fifties, I discovered auto movements and different styles of watches and as I developed an affinity for them and started wearing them all the time right up until the present. Thing is they weren’t nearly as rugged and found myself breaking quite a few. I’m now 61 and again found myself missing the ruggedness, looks, and features of the G-shock for everyday use. I’ll still wear an auto on occasion when I want to dress up, but I’m back for good I think.The GW-9400 is a beast. Thanks to the NM sun, it never needs winding. And thanks to the atomic time clock in Colorado I never have to set it either. It’s got a bunch of cool features like a compass, an altimeter, a barometer, etc, and they do actually work pretty well. But the greatest thing about it is its ruggedness. I’m pretty tough on my gear and I’ve broken several lesser watches in the past while camping, riding my motorcycle, or just putting around doing what I do, but in my entire life, I’ve never managed to break a G-shock, which ultimately is what really brought me back to them.Good looking, great product I can’t recommend enough. And at even its current price, it is an incredible value. If you’re on the fence, don’t even think about it. You’ll quickly find it’s a no brainer.

This is the best watch for the outdoorsman! I found this watch to be very useful as you can tell barometric pressure right from the timekeeping mode by a graphical display and a barometric pressure change indicator as well. This thing is also very easy on battery power even with the auto light function on. It has many more features than I can go into here. Some like the world time helps me know what time it is at home when I'm away some where like Utah, I live in California. I found it very useful while I was in the UK. The altimeter has a resolution of 1 meter which is very fine, it takes it's information from the barometer and air pressure can change in minutes so it's necessary to get reference altitude from a topographical map and set the altimeter accordingly before you set out for the day's endeavor and at easily identifiable points on a map along the was; see reference altimeter setting. The compass works quite well for getting bearings which are shown on the big display. The directional indicator is in the "small bezel " , the circular display, it has very fine lcd markers that show north, west, east, and south. It's actually pretty easy-to-use , I find using the strap laid out flat makes it easy to mark north and the bearing for your direction of travel.It can take temperature readings but you have to take it off for about 1/2 hour to get the surrounding temperature correct, remember that it's warmer inside a tent from body heat. On your wrist it's gonna read your skin temperature as well as ambient temperature.This is the reason i bought this Triple Sensor watch over the other ones... it, is a G Shock! Which means that you will always have a watch that tells time even if you beat the hell out of it But... i think the altimeter, barometer, compass internal sensors might be disfunctional after beating the hell out of it. Being a G Shock it will provide a bit more protection than say a Casio ProTrek or a Tissot or a smart watch. It looks great on my wrist and it's not too big. It's got a nice band and metal strap hold down. I think the buttons being cross cut is a fantastic idea and they are stainless steell. I like the sunrise sunset function too and the only thing I wish it had is a moon phase function. I use the sunrise function for night hiking and sunset so I know how much light I have left and when to kick back and watch the sunset and color show. There are many more funtions like alarms 5 of them, magnetic declination, 200 meter water resistant, and record keeping of altitude, barometer, compass, temperature. And it's the coolest Casio G Shock I've found and they call it the "master of G". To top it off they made it solar powered!. That's enough for now. RPG
