Wow! A watch and half!

I have been a g shock owner now for a long time and must admit my old model is still going strong. After months of thinking about and searching I set my mind on buying the rangeman and now after a few weeks of using must admit I’m very glad I did! The feel on the wrist is perfect and I have seen some reviews saying it’s chunky and to big but in my personal opinion it’s supposed to be built Chucky it’s part of what it is! The functions work perfectly and with the metal buttons being grooved they are so easy to use wet or muddy with or without gloves. Anyone that is thinking about buying this watch they should! Obviously that is my own opinion but I highly recommend this quality product

This watch is awesome! Great looking, light and very very well built with a premium feel.

Before buying the Rangeman GW-9400 I did a lot of research and I was divided between the Mudman, Frogman and Rangeman. I decided to go with the Rangeman because for me it looks better than the other two, it’s smaller and it’s the cheapest with the same great features.

Great for people that like going on holidays, doing sports, soldiers, pilots, action movie stars or people with taste .

The watch sits really nice on the wrist, the black goes well with almost anything but beware, it is not for everyone as it is a big chunky watch, not everyone’s cup of tea.


- Scratch resistant mineral glass – great for people that like to get their hands dirty!

-One button sensor button that combines three modes altimeter, compass and barometer - very easy to use and practical if you are a pilot forget about the Breitling!

-Solar Atomic powered – no battery needed. Hurray!

-Synchronizes the time with the atomic clock - you will always have accurate time.

-Power saving mode the watch will shut down in a very dark room to save battery and it wakes up when you start using it.

-Barometer – predicts based on the pressure and atmosphere, you can actually predict when the storms are coming, great feature for Ireland and UK.

- Sunrise/sunset mode: brilliant if you wake up early and want to enjoy the sunrise.


-Illumination not that great or uniform, probably Casio wanted to save some power.

-The strap has a stainless steel retaining ring that I personally don’t like as it will scratch in time.

-Very bulky and thick for some. It measures 55.2 x 53.5 mm in width and height and 18.2 mm in thickness, not so fancy if you are wearing a nice suit.

-A bit pricy for this type of watch.

-If you look at it from an angle it is difficult to read the time.

I have quite a big collection of watches from expensive to cheap, but I have to say that I really enjoy wearing the Rangeman on a daily basis. It’s very practical especially for holydays as you don’t have to worry when you go swimming or be afraid that the sand will ruin your watch.

So, if you are looking for reliable and durable tactical watch look no further. It has all the features in the world, it’s light and it looks amazing.


Keep the watch clean, wash it every week as it tends to get dirty fast.
