Product Description

The rugged and sporty Casio G-Shock digital watch features atomic timekeeping via radio signal for extreme accuracy, enhanced shock resistance, and water resistance up to 660 feet (200 meters). This solar powered watched comes with a power saving function and offers a battery life of 11 months on full charge without further exposure to light. The stylish gold-toned digital display comes with an automatic electro-luminescent backlight with afterglow, and three circular digital displays at the top provide additional information such as mode, timing, and battery level. The world time can be set for up to 29 different time zones (30 cities), with optional daylight savings and a city code display. The automatic calendar shows the month, date, and day below the time and is pre-programmed through 2099. This convenient, world-savvy watch also comes with a 1/100 second stopwatch, four daily alarms and one snooze alarm, a time recorder, and hourly time signals. Designed for durability, the watch is built with a stainless steel bezel and a mineral dial window. The dark gray case and band are made of resin and further the watch's ruggedly casual look. This watch is backed by a 1-year limited manufacturer's warranty.


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.

    It may have other functions, but since I don't use the watch for alarms or stopwatch, etc., I wouldn't know.

    This watch looks somewhat more sophisticated, though I'd NEVER wear it with a shirt and tie (that's what all my other watches are for!).

    To let you know how well it worked, consider this: The "Atomic Clock" signal originates in Colorado, northwest of my location.

    In 1989 I was working as a production carpenter. I had been through numerous low priced digital watches. All worked well and performed their primary tasks well, (time display), right up to the time that they broke. After buying a nice, high-priced Seiko for my wife on her birthday, she asked me what she could get for me. I told her that what I would really like would be a "Bullet-Proof" watch. I had heard great things about the "G-Shock". The next thing I knew I was wearing one.

    My first one, which is still running 18 years later, and on only it's second battery, turned out to be the most dependable multi-function time-piece I ever owned. It served me through years of construction work, diving and surfing, exercise laps in the pool, kayaking and rafting rivers in California, Idaho and Montana. Oh yes, being an unpretentious person, I also wore it to weddings and social events.

    Alas, recently the outer protective shock case finally succomed to the elements, cracked and fell apart, leaving the stainless steel case exposed, but still working, and still attached to the original strap, and the watch still works.

    It seemed prudent to retire old faithful and replace it, with a newer, upgraded model. Thats when I ran across this attractive and versatile beauty. The price was right and I was intrigued by the "Solar Power" and "Atomic Timing" features, so I went for it.

    The Casio GW330A-97 is attractive, extremely comfortable, and very eye-catching with its space-age design. With Casio's G-Shock reputation, I have no reason to expect less than the best in rugged and dependable performance. Now that I have learned how to program and access the many functions that this device offers, I am very stoked to have it, and all it offers, at my command.

    I have several other Casio watches and have found them all to be excellent performers over the years. This was my first solar, "atomic" watch. It is nice looking and the rubber band isn't too stiff - very wearable. The watch seems to charge well with even moderate exposure to direct sunlight. Now for the things you should think about before buying it.

    1) The face on this model has three little (very little) dial-like indicators that are very difficult to see and make sense of. Other Casio models with the same features have a face with a different design and indicators that make more sense and are easier to see.

    2) The "atomic" watch-setting feature means the watch needs to receive the very-low-frequency signal from WWVB (U.S.) to set the watch. I have several "atomic" clocks in my home and office and all of them set themselves nightly with no problem. This watch doesn't. Apparently its receiver isn't as sensitive as those in the clocks and it will only receive the signal when placed in window facing Fort Collins, CO. I finally found one place in my house where it could receive the signal. If you live in a big city with lots of buildings or any place where AM radio reception is poor, you might have a problem with this feature.

    3) The function buttons on this model are recessed into "protective rims. I'm sure this is to protect them for damage and accidentally being pressed. However, it also means that you must use you fingertips to press the buttons - possibly your fingernails if you have big fingers. For stopwatch functions, it is much more difficult to use than models with exposed buttons. If you use the stopwatch function a lot, this would be a real issue.

    Overall, it's a good watch, but other models with similar features might be better for some of you. Look at them all.

    This is my second G-shock. I got this one because I really like my first one. Overall, it's not a bad watch. The numbers are large and easy to read, and the backlight works really well. On the other hand, the buttons used to set the watch are very hard to manipulate as they are set in the case of the watch. Also, it is very hard to know if any of the alarms are on/off as that display is very small and hard to see.

    This watch uses the Casio 2688 module, which is functionally equivalent to the 2608 and the 2638 modules with one important distinction. The latter two depict information like charge levels, alarm status, and watch settings with simple well-marked text indicators on the LCD watch face. This model uses "pie wedges" in three circular pies at the top of the watch face. I bought it because they looked cool, but the indicators contained within are barely visible. Also, their meanings are not at all intuitive, just one more thing to remember, and one more reason I will have to keep the manual around for the life of the watch. It's not a big enough issue for me to return it, but I would recommend the more straightforward design.

    Other watch owners seem to want instant gratification from the atomic time function. On the east coast, I really can't set the watch in the daytime (even outside), as the shortwave signal probably can't get the appropriate skip in the daytime. However, the watch does successfully set itself automatically overnight, and it's on a bookcase in my hall, not near a window. Besides, the WWV sync only needs to be successful every month of so, and I will still never ever have to set the watch or change a battery. I find this amazing in a ~$60 watch, and I bow down to the technology gods!

    It's not a beautiful watch, but the functionality and value for money is unquestionable.
