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

Nice, inexpensive, works well
I like analog watches, but occasionally need a stop watch, timer, alarm, etc. This one fits the bill almost perfectly. It's also inexpensive enough to not worry about.

However... the crystal is pretty soft, and it scratches easily. If you work in an office and move papers and a mouse, it'll probably be fine. However, I work with tools and am fairly hard on the things I wear. The band is plastic, and when you sweat, it gets a litle slippery.

For the price, it suits me just fine - I'll just throw it away in a few years when it's all beat up.

A basic timepiece at a great price
I have had this watch for @ 2 months now. I say for under 20 dollars it's a pretty good watch. It has kept perfect time over 2 months. It is lightweight and the band is very comfortable. I like having the analog hands and being able to display the digital date/time.

Now in no way do I expect this watch to be anywhere near the quality of my Citizens Chronograph, my Invicta Diver or my Swiss Army Officers watch. The Casio is a watch I bought for bumming around.

On the negative side, the light does not do a very good job of illumination. Additionally, setting the time is really cumbersome. Setting the anaog time is not too bad, but setting the digital date and time is really a pain. Keep the instructions handy, you will need it when you have to change the time.

All in all, for @ 15 dollars, it is a nice decent watch. A good value purchase

Very good watch
My previous Casio analog / digital watch was wearing out. Its digital screen was so tiny that it was nearly unreadable.

This watch met and exceeded my expectations. It is easy to set and operate. I like its non-gaudy and stylish appearance. Its digital display is easy to read. The promise that it could run for 10 years without adjustment based upon its perpetual calendar and lithium battery is also attractive.

There are minor problems, but they don't really detract from the overall rating (5 stars).
- If you insist on checking the time in the dark several times a day using the internal light, the battery won't last the full 10 years. (The 10 years is based upon one 1.5 second check per day.)
- The rated accuracy of +/- 30 seconds per month is not so great, but I'm expecting it will exceed that as my last Casio watch did.
- One can only go forward, not backward when setting the analog time, which means that if you overshoot the time, you have to watch the minute hand go 'round again almost 12 times.
- There is no second hand.

I wasn't expecting perfection for under $20; I am certainly very pleased.
