I love casios and am always tempted to add to my collection of G-Shocks due to the sheer genius of their technology. This watch keeps time perfectly by syncing to an atomic clock everyday, but requires you to do nothing except keep it near a window. It uses Solar Power to keep charged, and will automatically go into power saving mode if it detects that it is not being used, or is in the dark for an extended period of time. Along with the fact that the watch is indestructable (if you're bored go onto the US G-Shock site to see what this watch can do), it is amazing to know that even if you store it away at any time, you simply need to let it soak up some sun, collaborate with the atomic clock, and it will be ready for use again. Moreover, I love the idea of having a moonphase indicator which is why I bought the 7900, although the dial isnt as big as I wanted (Casio PLEASE make a watch with a real emphasis on its moonphase indicator), it still does the job perfectly, along with a tide graph, which looks really cool. Both elements are great to see as it makes you think of nice, natural images of the sea and the moon. Besides this, it has everything, anyone would want from a watch. On the home screen, you can switch between a day/date indicator and a dual time zone; the stopwatch is obviously very capable and responsive; the timer works well and gives you up to 24hrs; the alarms and World Time work well, too. The watch is aesthetically very cool to wear if its your thing, and you like a large watch. Although, more so than other casios, it is more subtle and military looking, with only the middle part of the display showing red, with the rest of the watch being uniformly black (which I personally like). The watch also wears very comfortably.

Some Cons (I hope Casio reads this!

Having been hooked for the last 2 years with my retro Casio databank calculator watch. I thought I should get something a bit more robust for my day-to-day walking, cycling and DIY activities.

I originally wanted to get the G version of the watch -the ones that's in the new 'End of watch' film that's coming out. However, this one came reduced by 27% and had solar and atomic clock features. So I got it.

First impressions were impressed by the quality of the watch, didn't feel that cheap way that g-shock pretenders possess. The only slight downside -and I mean a very very minor thing-was the watch catching on my sleeve due to chunkiness, but I soon got used to it - plus it's good to keep the watch out in the light whenever possible.

I've had no problems with setting watch up or maintaining power levels. My instructions were missing, but that was not an issue as you just log onto the Casio website, stuck in the 4 digit code on the rear plate and there they were. The auto light function performs better than the same feature on my calc watch. Great little feature.

Overall, Great watch that is excellent no matter what you put it through envionment-wise.

I'm a G-Shock collector and this model was one of my first purchases.
Moon/Tide graph display, World time, Stop watch, Multiple alarms and a countdown timer all feature on this model.
I liked the classic G-Shock looks of this model and although other colour variations are available, this is still a classy looking model.
The size is quite large though, so for people looking for something more discreet I would try a smaller G-Shock like the GLX-5600 which shares most of the same features.
However, despite it's size it is very comfortable to wear. On the underside of the watch face are two supports which form part of the strap and which help to keep your watch squarely on your wrist.
The radio controlled time keeping is 100% spot on and overall set up was very quick and easy indeed. View the manual on pdf doc via the Casio UK website if you need to.
The moon and tide graph are set up in accordance to your home city. Choose your home city on initial set up and the correct Moon/Tide display is automatically generated.
They also work correctly and I have checked this using both Star Walk on the ipad and internet websites. You can manually adjust the Moon/Tide graphs should you need to though.
The watch oozes ruggedness and despite it's size it is still light in weight.
An excellent, feature packed, easy to use watch that will certainly withstand the test of time and being rugged and tough meaning you can wear it virtually anywhere.

Bought this watch for work, as builing sites are pretty rough places.

Watch lookes great , and all the features are excellent, however the moon graph and tide display are pretty much next to useless. The 5 alarms are brilliant, for a heavy morning snoozer or for regular reminders.

Setting up the watch is relativly easy , just pick the city and hit the auto receive button and hey presto, time ,date , tide and moon all set.

The solar panels are hidden around the top and bottom of the face, it's an idea to leave it on the window ledge for a few days to charge the battery, but don't worry when the screen goes blank, It's entered Power Save mode, it'll return to display with a press of any button.

One thing I'd say the watch is a very dark grey , not black , and very chunky, but if you like G-shocks , then you'll love this! It's tough , easy to use and looks the part. I had an old G-shock years ago ,which died in the washing machine at 40 degrees!, and after buying this one I'll never wear another watch to work I'd forgotten just how good they are.

So all in all , it's a great tough watch, won't let you down but just remember to take it out your trousers before washing them!
