    The Casio Story
    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.
    In developing its own wristwatches Casio began with the basic question, "What is a wristwatch?" Rather than simply making a digital version of the conventional mechanical watch, we thought that the ideal wristwatch should be something that shows all facets of time in a consistent way. Based on this, Casio was able to create a watch that displayed the precise time including the second, minute, hour, day, and month — not to mention a.m. or p.m., and the day of the week. It was the first watch in the world with a digital automatic calendar function that eliminated the need to reset the calendar due the variation in month length. Rather than using a conventional watch face and hands, a digital liquid crystal display was adopted to better show all the information. This culminated in the 1974 launch of the CASIOTRON, the world’s first digital watch with automatic calendar. The CASIOTRON won acclaim as a groundbreaking product that represented a complete departure from the conventional wristwatch.
    Casio transformed the concept of the watch — from a mere timepiece to an information device for the wrist — and undertook product planning based on this innovative idea. We developed not only time functions such as global time zone watches, but also other radical new functions using Casio’s own digital technology, including calculator and dictionary functions, as well as a phonebook feature based on memory technology, and even a thermometer function using a built-in sensor. The memory-function watches became our DATA BANK product series, while the sensor watches developed into two unique Casio product lines of today: the Pathfinder series displaying altitude, atmospheric pressure, and compass readings.
    In 1983, Casio launched the shock-resistant G-SHOCK watch. This product shattered the notion that a watch is a fragile piece of jewelry that needs to be handled with care, and was the result of Casio engineers taking on the challenge of creating the world’s toughest watch. Using a triple-protection design for the parts, module, and case, the G-SHOCK offered a radical new type of watch that was unaffected by strong impacts or shaking. Its practicality was immediately recognized, and its unique look, which embodied its functionality, became wildly popular, resulting in explosive sales in the early 1990s. The G-SHOCK soon adopted various new sensors, solar-powered radio-controlled technology (described below), and new materials for even better durability. By always employing the latest technology, and continuing to transcend conventional thinking about the watch, the G-SHOCK brand has become Casio’s flagship timepiece product.
    Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, and the radio-controlled function means users never have to reset the time. In particular, the radio-controlled function represents a revolution in time-keeping technology similar to the impact created when mechanical watches gave way to quartz technology. Through the further development of high radio-wave sensitivity, miniaturization, and improved energy efficiency, Casio continues to produce a whole range of radio-controlled models.

    Good Watch5
    Top 10 Gadgets of 2009 (Rated #8) according to Time magazine. This is my first G-Shock and first watch with an inverted display. I wanted a sturdy watch that I wouldn't feel would break if I banged into something. I have several Citizen, Tissot watches that I just felt were to prone to being scratched/destroyed.

    I'm very happy with the design/look of this watch. The pictures (as of today) on Amazon are distorted and don't do justice to the look of the watch. While this watch is a very large watch compared to some of the other G's, it feels nice and comfortable on my wrist.

    I wanted a watch for functions as well as reliability. With the watch being solar powered, along with an atomic feature makes this watch a must have. The watch has alarm's, timer, dedicated button (the G button) to the light which is very nice (can work in any mode), 2nd time zone, world time, etc.

    I've gone through a lot of watches in my time but this by far is one of my favorites and is a must have in your collection if you're looking for a reliable, sturdy, function filled watch!

    1/5/10 Follow-up:

    Since I'm an avid Scuba Diver, I wanted to know if this particular watch can be operated underwater (switching through operations on the watch).

    This is the response I got from Casio-

    "Dear Mr. Travale,

    The GW7900B-1 has a water resistance of up to 200M. These models do permit underwater button operation.


    We hope that we were able to assist you with your question and again, thank you for contacting CASIO AMERICA."
    A great do just about everything watch.5
    I have had the GW7900B for 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. The fully charged battery is supposed to be able to last about nine months without a recharge, but the solar panel in the watch face picks up a charge in direct or indirect sunlight keeping the watch battery topped of unless you hide in a dark room all day. When I first received the watch the battery indicator showed the battery was a little low. I put the watch in indirect sunlight by setting it on a table by a window that the sun does not shine through. About 3 hours later I checked on the watch, and the battery was fully charged. Since then the battery has remained fully charged with just the partial sunlight the watch gets from me commuting to work. So I don't expect any battery problems. A cool feature for those of you who may not use the watch for a while, it turns off late at night and will not turn back on until you pick it up. So the battery does not drain much if you do not use the watch. 3) I travel across the country for work, and the watch is very easy to reset to other time zones. It also has a world time feature that lets you check the time in every time zone around the world just by clicking through the different zones. 4) Like just about every digital watch this one also has a stop watch. The stop watch capabilities are not as thorough as sports watches. For example, you can get a split time, but you wouldn't be able to take several split times like you could with a Timex Ironman watch. 5) The watch has a countdown timer so you can let yourself know when you need to stop what you are doing and move on to the next thing. 6) There is an alarm function that allows you to set four alarms and one alarm with a snooze feature. 7) The watch shows the phase of the moon and where tide is. 8) The watch is water resistant to 20 bar, which converts to something like 170 meters. So you can pretty much wear the watch in most underwater conditions you will find yourself.

    So to wrap things up, this is turning out to be a great watch for me. It is super accurate, does not look like it will ever need a battery change, and looks really nice. I recommend it, and I would buy it again.

    Different G-Shock5
    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.
