Product Description

With the multifunctional Casio Men's G-Shock Solar Atomic Black Digital Sport Watch, you'll finally be able to mix business with a little athletic pleasure. The case and bezel are both made of black resin, tailoring to your more sophisticated side by offering a sleek look and smooth feel. Four large silver screws accent the top and bottom of the bezel that displays blocky white words depicting the four button functions. The dial hosts five subdials depicting time, date, and even tide charts for the boating enthusiast. Easy-push buttons on the case allow you to quickly go through your settings and work the handy stopwatch feature, while a soft EL backlight provides you with access to the time regardless of where you and your watch are. The wide band also consists of black resin, closing with a silver buckle for a custom fit. This sporty timepiece is water resistant up to 660 feet (200 meters), relies on Japanese quartz movement, and boasts Casino's shock resistant technology.

Casio

With the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.

Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

    Time display is easy to read in all lighting.

    I've never had the solar power indicator fall under the "High" mark and the atomic clock syncs every night without issue.

    I've had 3 different G shock atomic watches and I like this one best so far.

    I have had the GW7900B for a year and a few months now, and I am very happy with it. The watch is all black, and the digital face is inverted so that it is black with light gray for the numbers. That means the watch is pretty much all black, which is a very nice look. The inverted digital face does make it a little tough to read in low light situations, but the G button just below the watch face lights up the time, date and other information with the same kind of indiglo effect that I have had for years with Timex Ironman watches. The lighting effect makes this watch easy to read at any time. You also have the option to have the lighting effect happen with the turn of you wrist so you can see the watch information without having to push a button. This is a large watch. The body of the watch is almost 3/4 of an inch thick, which is the thickest watch I have come across. While it is a large watch, it is very light, because most of the body is plastic. The face of the watch is scratch resistant, and it is recessed into the watch about a quarter of an inch, so it is well protected.

    The watch is loaded with features. 1) The time is set every night through radio signals from an atomic clock. Every night at a few minutes after midnight the watch will try to update the time from the atomic clock. If it is unable to update the time, then it will try again every hour through the night until it gets an update. This makes the watch very accurate. It has been off by less than half a second from any of my other atomic clocks or the atomic time that you can get over the internet. This will be the most precise watch you will probably ever own. 2) The battery on the watch is recharged by solar panels in the watch face.

    Me to larger-than-life Navy SEAL: "hey we wear the same watch!"

    Him: "yeah yours is better though, it's got these raised screw heads."

    Me: "oh those are just for show, people on Amazon even complain about them."

    Him: "no... see, if you wear it on the inside of your wrist like me, it's a great weapon when you attack the face. I learned that while boxing in Brazil. Glancing blows scratch near the eye and blind the opponent."

    Me: "you obviously shop differently than I do."

    Nice attractive watch. I really like the solar power and atomic timekeeping and the unique look for me was a plus. Of course, as others have mentioned, it is difficult to read under low-light conditions, but that was something I was willing to put up with for the unique look of the watch.

    Unfortunately, contrary to my very positive experiences with previous G-shock watches I've owned, this one broke within two months of purchase. Hence my rating.

    Now, for additional background information ... I sent the watch to CASIO for repair and that's where my troubles continue.

    A week or so after I sent the watch in for repair (they have one central repair facility on the East Coast), I learned they could not repair my watch. No surprise. But I also learned they did not plan to send me a like replacement. Instead, they offered me three potential substitute replacement watches. I was surprised with that, since the watch is still listed for sale on CASIO's website, but apparently they didn't have one in stock at their repair facility, and they were hoping I'd go for their substitute.

    However, the substitutes they offered did not have similar features (none were solar powered and none had the automatic timekeeping function). Further, all were substantially cheaper watches. In other words, they were not suitable subsitutes. To make a long story short, I'm still working with CASIO repair, after four phone calls and one FAX, trying to get resolution on my watch repair problem.

    Bottomline ... so far CASIO warranty has been pretty meaningless. Hopefully that will resolve

    UPDATE: I finally convinced CASIO repair that the substitutes they offered were not suitable, and after about three weeks, they agreed to find me an exact replacement. They made it sound like they were doing me a favor, rather that providing a guarantee, but as long as I got the watch replaced, I didn't care. The replacement watch is working fine.

    Received this watch earlier this week, very different from the traditional watches. The reverse LCD display is a bit difficult to set in low light as you can not do setting functions and see the display while lit. Still the display is easy to read other times in low light by just hitting the light really just an issue of getting use to it. The case is a bit larger than say a 2300 series Casio but not by much, it fits under the cuffs of most but not all of the dress shirts that I have at least. This model seems to receive the atomic clock signal better than the others I have (GW800 and PA1300). Buttons are very easy to manipulate but set in the case in such a manner I have yet to accidentally activate them. All in all a very nice piece and for someone wanting something different than the normal digital G-Shock I highly recommend it. It does have a high profile on the wrist though so if thats a concern there is always the old stand-by 5600 series watches that refuse to die that do have a much lower profile. Hopefully no bugs will avail themselves over the longer term.
