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

I love my Casio calculator watch
I own the basic black, no backlight, Casio calculator watch. The first one I owned, the battery lasted for 10 years (turning the button beep prolongs battery life) and I lost the watch when the watchband finally broke.

When I went to replace it, I upgraded to a more expensive model that had a backlight on demand and stored phone numbers and appointments. The battery only lasted a few months. I replaced it and it lasted only a few months again. I bought another basic model.

I've now had that watch for three years and still going strong. I bought one for my teenage son and he loves it.

You get:
1. a digital watch that shows day, month, date year and time
2. a calculator that does simple math functions (buttons are small and take some getting used to
3. a stopwatch
4. an alarm clock
5. dual time function (can be set to show time in another time zone; I've never used this)
6. a watch so cheap, you don't have to worry about losing it and muggers don't want (this actually happened to me, the mugger wanted my wallet and my watch. when he saw my watch, he laughed and told me to keep it).

all for under 20 dollars. you can't beat this functionality for the price. I'll never buy another watch. I was recently given a t-shirt with this watch on it and the caption "Genuine Bling". True dat.

This is a great watch!
I have owned a half-dozen of these watches dating back to the late 70's. Each one has lasted about five years. I have found it cheaper to just buy a new one on sale at Wal-mart or Target (or Amazon) rather than have a jeweler replace the battery. I find the alarm the most used optional feature, followed by the calculator, the dual-time (great for travel, and the stopwatch. It is very light-weight yet surprisingly rugged and easy to operate.

Good watch! Good Price! But it could use a light
The watch is great because casio makes great long lasting watches, but it would be nice if it had a light. The other less nicer ones from Wal-Mart have a light. But it is definitely worth the buy if you're a casio watch fan. Nice classic look and endureable too!
