This is an excellent watch in many respects BUT to get maximum display illummination, it needs to be fully charged. At anything less than full charge, the display looks dark, especially indoors. Its a monor issue as you can always use the light button.
I bought this watch to use in the hot and sunny climate of Egypt, where the illumination issue does not arise, even at night time. This is a CASIO watch, so it is naturally rugged, accurate and reliable. It has the usual buttons which are easy to manipulate even with gloves on. There is a thick manual but I dont hink you will need it as the controls are very intuitive.
The good bits about this watch and why bought it are:
1. Waterproof to 200m. I use it for scuba diving and have been to 65m with it, without a problem.
2. Its rugged. Its been banged about by accident a few times. What do you expect on a rolling boat! No scratches or dents. Just give it a wipe and its fine.
3. Its mud proof the writing on the strap says mud resistant. Ive had it in serious amounts of mud - without a problem. The gel buttons do not allow anything to get in. A quick dip in water and its as good as new. The same for deposits of salt water!
4. Finally, the square shape and the dark numerals give it a stealth look. Great for wannabes everywhere!

Awesome !

That is all I need to say about this watch, big bad and wont be missed on your wrist. I know Watchshop ask for product review but I think their service needs highlighting first. I ordered the watch at 1400 on Friday and it arrived 1200 noon on the Saturday. Im amazed by the service so do not worry about these guys... first class!

Now to the watch:

The watch is perfect in this regard. I am really impressed with the fit and finish. I have bought a few automatics at a far higher price only to receive them and find flaws in the crystal, bezel or other areas. It seems a little odd to look at the build quality of a plastic watch, but I think it really is put together well. Nothing misaligned or damaged.
It feels sturdy sits well and holds it position on the wrist.The strap feels comfortable with a cool buckle.

Daily wear:
As I said before I have only had the watch two days, but I wont be taking it off my wrist for some time.... well only for work as this is far to big to wear with a suit. The watch wears a lot smaller than I was expecting.Its comfortable. Very comfortable. I like the plastic rear case cover, it seems to make the watch stay put rather well. After about 20 mins, it stopped feeling weird and big and just felt comfortable.
I can however see people taking issue with the thickness of the case. It certainly doesnt wear well under a long sleeve shirt, but if you like a thick case, then you will certainly like the GX.

For me this is the best G-Shock I have seen for many many years. I have never owned a G-shock as I have always had doubts about the brand, but I decided for 2013 I would take the plunge and started by looking at the Mudman and Frogman. I am so glad I decided on this one! Nothing comes close to the King of G!!!!
I think the mud resist buttons are cool Does the Gel really do anything? Given how tough G-shocks already are, I have no idea if the gel is anything aside from hype and an excuse to make a larger watch. If there would be the kind of jolt that would damage an average G-shock, I would be more worried about the health of the person it was strapped too.

GO on buy this you will not regret it. And lastly..... Well done Watchshop +AAAA service.

This watch is extremely BIG.

If you dont want to stand out, then walk on.

Yes it can be criticised for its basic functions, it has 2 time zones, stop watch and a few alarms, but not mutch else.....

Its all about bulk. And if you want the bulkiest, most OTT G-Shock then this is your baby!

The GX56 also known as The King of G-shock is an ultimate mix of strength and style. Being a G-shock it is undoubtedly strong and if one thinks it is going to look too big in your hand then that is not the case. The back cover of watch has extra rubber protection which also makes it perfect fit for wearing. The negative display stands out from rest of the watches which also makes GX56 looks bit extra sturdy.

It has all necessary features such as 20 bar water resist, solar battery, hourly chimes, 5 alarms, snooze, world time, DST for local and world clock, start-stop, countdown timer, back light with auto illumination can be switched on/off.

The fitting of watch is a perfect on any hands and this is due to extra rubber protection on the backside of the watch. Not all the watch has this shield as GX56 has. It looks perfect with any costumes ranging from swimming trunks to business suits.

The added value is that it is a square module which gives a military looks. I have looked this watch in freezer for 30min, in water for 30min and I use it at my job, in gym and running on roads in rainy weather. It beats every possible climate. If I was a astronauts I would have took it with me in space so that I can make sure I have accurate time of planet earth.

The service was excellent!
I ordered the watch on Sunday and it came to me on Tuesday.
Im very impressed!
The watch is great! Love all the features. its robust and it is easy to change settings. Really like the velvety black look with the red contrasts. The only thing that could be made better is the display. I think that the display isnt very clear.
But over all I love the watch!

Wow what a watch and what a service after checking out a few other websites i found watch shop to be amongst the cheapest for this gshock and i got it the following day.

Its a great watch with loads of features and looks chunky and robust enough to for me to wear swimming and cycling, i have 3 others g shock but this is by far the biggers and best yet, i think this is the biggest watch you can wear without looking ridiculous!

A must have for any gshock fan and you know its the real deal from watch shop!

I brought this as a gift for my fella who is a gshock worshiper, he has 6 and counting. I was looking for the ultimate gshock for Xmas for him but had a budget of just over £100, I saw the king of G and thought that's it. It looked amazing on the photo. The watch came really quick and when I looked at it, I was even more impressed, the size of the face was big compared to his others so instantly made a statement, the red lining of the face gave it an even more wow factor. The quality was exceptional for the bargain price compared to other retailers. When I gave it to him, he was over the moon and has rated it as his best g shock by far. The strap is tough and comfortable as with his other g shocks but the red writing on the straps makes it more special, the watch is over sized and excellet for any g shock lover wanting to say look at me! Big thumbs up from menand even more bigger thumbs from the other half.
