    • Good value for money.
Great Watch. ABC sensor works as described, and black display is very easy to use even in direct sun light

    • Love this watch, I have two
This watch does everything that it’s showing to do, I have the pink version that came from Japan that was $700 it’s the same watch as this one and I got this one for work, this watch I believe I paid $320 for plus tax and it works flawlessly It has a barometer, compass, altimeter, it has everything and everything works plus the nice part is it is solar powered and you don’t need to replace batteries they’ll last for probably 10 years if you take care of it and then those batteries at that point can still be replaced but after 10 years you might want another one I know $300 for a watch sounds like a lot of money but it’s so much more than just a time piece and they’re rugged as hell I’ve used these watches from G-Shock for decades and they just keep getting better and better, the reason the pink one was so expensive is because it was a limited edition from Japan and they offered those in a couple of rare colors and I just liked the dark pink and so my wife bought it for my birthday and surprised me but for work I prefer black The case and the band are black but it’s not a shiny black it’s a flat black, the face is black behind the crystal and the numbers are dark in the data but you can still read them easily, I like the automatic light where you just hold the light button down for three seconds and then it puts it in auto mode and hold it another three seconds and it turns it back to manual mode sometimes at night it’s nice to have it on automatic because when you rotate your wrist forward and then rotate it back where you can read the time the light comes on for one second or three seconds which you can adjust as well this watch is amazing nobody makes a heavy duty watch better than Casio ... show more

Just as described! Beautiful watch, big size, easy to set up. Its a bit hard to read in low light but just press the light button and have a perfect contrast.

    • Excellent Watch The Strap Is Too Thin
5 or 6 years ago I bought a blacked out King G - GXW 56BB from Japan and really love it. I am a big dude and am pretty hard on watches. Usually I have to replace the bands on my G shocks once or twice a year. Finally tore up the band on my King G a few weeks ago. Had to bump around on several sites to find the replacement strap for it. In the process I started looking at G Shocks and thought a blacked out Rangeman GW 9400-1B would be a nice watch to add to my collection. Its a little smaller than my King G and so far I really like it. Because it has more features and the buttons are much easier to push. The only thing I don’t like about it is the strap. Its pretty thin and I know I will tear it up within in a year if I wear it to work and I have been wearing it to work. Once I receive my King G strap I will no longer do so.

    • Beautiful G Shock, lots of utility, subtle and hard to read
This watch is incredible for its multiple purposes and functionalities. I wanted a durable watch that was solar powered with various tools for survival like a compass, barometer, and altimeter. The only complaint I could find from other reviewers is that the watch is hard to read in certain lightings. While I agree, this isn’t an issue for me. I don’t need my watch face constantly illuminated even when I’m not looking at it, and the blacked out version is very stealthy and subtle which is what I was looking for in a survival watch. 10/10 ... show more

    • Worth the purchase
Review Image by J. J.
I think the only thing I didn't really like about this piece was it doesn't have a step counter. Outside of that I really do appreciate the style and the simplicity of the display. It is light weight for the size. I have never been someone to wear a watch due to having to change batteries. Or with the smart watches having to charge every few hours and not able to wear it when charging sigh defeats the purpose of a watch. But this watch's battery should last I believe around 10 years and even though it is on the larger side it still manages to blend well into whatever you wear it is very understated and that is what I appreciate about it the fact that it isn't a flashy piece screaming look at me I love the matte finish of the case and strap. Its hard to find highly functional piece that isn't Bluetooth or a smart watch. The fact that you can have multiple useful functions without having to worry about a source of charging the watch is nice. Even though it is considered a man's piece it still can be worn on a smaller wrist and doesn't look out of place on a female. As I am not into smaller pieces for women they are usually more casual to dress watches but not durable for an active life style. I'm not hard on my things but I don't want a time piece that I have to constantly be aware of. When it comes to day to day activity and one that I have to be reminded of to treat with exceptional care and having to take off just to wash my hands rinse dishes for the dishwasher or even to take a shower I wanted and needed a piece that I can put on forget about until I need it. This does the job perfectly ... show more

It's some kind of horror, not a watch display that's so awful that it can't be conveyed. You have to twist your hand to catch what time the clock is showing now, even with the backlight, it is very difficult to see during the day, in the dark, the backlight saves. And besides, in the photos, the seller put up beautiful clear photos, but in reality, everything is not so. Everything is dull and dark on the scoreboard. ... show more
