Amazon.com Product Description
The Casio Men's Classic Digital Sport Watch features an intuitive design that makes it easy-to-use for on-the-go athletes. The timepiece is constructed with a durable resin case, a stationary black resin bezel, and a black resin band with an adjustable buckle clasp. A durable mineral window shields the square digital-gray dial face, which features a digital time display along with the day, date, and month. The watch also includes light, mode, and adjust buttons that allow you to personalize your watch display to suit your workout. The digital-quartz-powered timepiece is water resistant to 330 feet and comes with a one-year limited manufacturer's warranty.

Development of the Timepiece Business
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.

Customer Reviews

Everything I expected
This is a nice watch with more features than I need. I use it for sports training because the digits are very easy to read at a quick glance. I have not used the alarm or other features and doubt I will. I do like the date and day of the week features. I also bought an analog dial watch for more formal occasions. The price was right for both watches. I don't buy expensive watches so these fit the bill for features and price.

Not a G-Shock - but that's a good thing!
Just got this watch after ordering a few days ago. Strange thing is, you won't find any product information about it on Casio's US website. Let's get to it:

Pros:
1) Not as bulky as a G-Shock:
If you're like me and you want a fully-functioning digital watch without the enormous bulk of a G-Shock, then this watch may fit your bill (even the midsize G-Shocks are tad too large in my book). However, this watch isn't tiny either: The across-width, measured between the buttons on either side but not including buttons, is just a 1/16 inch shy 1.5 inches. The top-to-bottom height, measured between the outside of the top bezel above the "Casio" insignia to the outside of the lower bezel below the "WATER 100M RESIST" is 1 3/16 inches, and just about 1/2 inch thick.
2) Plenty of features:
Dual time, stop-watch with split times, displays the time during the stop-watch function, date setup that knows the day of the week (accounts for leap year too), large display, snooze alarm (!), etc.
3) Great price:
For the value alone I give it the 5-star rating

Cons:
1) Bezel around the crystal is flush with the surface of the crystal - this could lead to scratches if you're not careful
2) Light is not the back lighting "Illuminator" of some other Casio watches - it's green glow that lights from the bottom-left of the display - kinda meh but it does stay on for a few seconds after depressing.
3) Could use a count-down timer.

In closing, this watch isn't gonna win any beauty contests, but it's functions, simplicity, and discrete look are what sold me.

It does the job it's advertised to do.
I got tired of paying $25 to $30 for digital watches that have both the battery and the band go out at the same time, necessitating a $15 expenditure on the watch, so I got this one. It fits well, and keeps good time and it's not bulky and in the way. To prevent scratching, I cut a fitted piece of PDA plastic cover to put over the face. It self-adheres and is easy enough to remove and replace when it gets scratched. If you cut it right, you can't even tell that it's there. Why Casio doesn't make replaceable covers to begin with, I'll never know, because you know what? They'll never tell me, even if I ask nicely.
