5.0 out of 5 stars Excellent watch -- dependable, long lasting -- great for nurses March 5, 2008

By Blueberry mom

I've had this watch over 15 years, close to 20. A long time. I bought it at Targ*t. I had it in college, nursing school, wore it when I started my first job on night shift and it is still going strong. It is a super watch. It is a great watch for nursing. The light works well in dark rooms, the alarm is easy to set, the watch is waterproof for all those hand washings! I also always wore it in the pool- no problems. I think I've had to change the battery and band only once. Sturdy, good quality.

5.0 out of 5 stars Great for my non-terrorist timekeeping activities! April 25, 2011

By Mabuk

As a non-terrorist I find this sits very comfortably on an infidels wrist. I principally use it as an IET (improvised egg timer), and would heartily recommend it to anyone (not being occupied by an imperialist banana republic) who wishes to launch a Jihad against runny eggs. Casio be praised!

5.0 out of 5 stars Basic Casio Watch--A Ok April 25, 2008

By Laurentz Lewis

I'll keep this short and sweet. This was my first digital watch nearly twenty years ago. I've had many since, and yes, I searched for this one and bought it. Why? Well, it's like me concise and to the point. Gives you what you want and need without the frills. Loved it then and love it now.

The Casio Story

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.
