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

Excellent Digital Watch
Over the years, I have bought nothing but this particular watch. I got my first 6 years ago, and had it for 4 years until it met its end in the washing machine. I drove over the second (whoops!) and am now on the third. The reason I keep coming back to this particular watch is that it is rediculously easy to set and use. In the traditional time mode, there is an option for 10 seconds of backlighting, and a toggle between 12 and 24 hour mode. Press "mode" and you continue on to the alarm settings. You can toggle the alarm on and off, as well as set a chime for the hour. The exact same process is followed to set the alarm as to set the time. Press 'light', then use the 12/24 button to increment the fields, and 'light' to continue through all the fields. If you changed anyhting, pressing mode returns you to the time, otherwise, pressing mode again takes you on to the timer. 12/24 starts the timer, light spltis the time, and 12/24 again stops the timer. Pressing light while stopped clears the entry. Pressing mode returns you to the time if you used the timer, otherwise, it continues on to the set-time screen. This behaves the same as the set alarm screen, except you also set the date here.

After 6 years of using this model watch, I have found exactly two problems.
1) The date didn't increment to Feb 29, 2000. It went to March 1, 2000. But I was able to manually set it, and it's been fine ever since. We'll see what happens Feb 29, 2004.
2) My first one had a type of cloth for the wristband. It wore out relatively quickly, leaving me with the watch but no band. The plastic/rubbery band is much more durrable.

But the positives are much more numerous:
1) Extremely easy to set.
2) Batteries have never wore out on me, and I use the backlight frequently.
3) Nice backlight.
4) Logical "menus"
5) Intuitive navigation - I am a computer programmer, but I've had other digital watches that I could not navigate through with the manual. This one is usable without a manual.
6) Year 2000 compatible! :)

This watch is worth far more than Amazon (or anyone, for that matter) charges for it.

Had it for 10 years now!!!
I didn't buy this at amazon but from a Casio outlet for 15$ about 10 years back. Strap cracked in a couple of years and I replaced it with ones you can find at walmart. Great watch. I've tried, tested, scratched, dropped and used it for 10 years. I will not give this watch away ever just because it is nostalgic for me as well as a work horse. Needs battery replacement now since the illuminator blue light has turned dull. I think I've done it once before but that's it.

Great simple digital watch with alarm, and stop watch. Buy it if you can below 15$ but expect to change the strap in a couple.

Great Everyday Watch
I didn't buy mine from Amazon but I thought I'd submit a review here nonetheless. This has been a great everyday watch for me. I'm a warehouse manager and I've worn this watch to work everyday for the past 2 years. To steal another companies catch phrase "it takes a licking and keeps on ticking". I've never had a problem with it and I've only just replaced the original band 2 weeks ago. I couldn't find a Casio replacement strap so I had to go with a Timex (plastic) that was very close but with not quite as nice a feel. At this excellent price it's almost better to buy a new one versus replacing the strap but it's been so good to me I just couldn't bear to throw it away before it's time.
