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

very versatile watch
This watch is great for using in the healthcare field. Its water proof, and it has both a digital and analog display WITH second hand. A second hand is a must for counting pulse and respirations. I always have the digital time set to 24 hour time, and I use the analog for everyday 12 hour. It also has a separate display that shows the current day and date. Having all of these features displayed at once (24 hour, 12 hour, day, date and second hand) is just very convenient. I liked it so much that I bought another in case something happens to my first. Good job Casio! Nice practical design. Thanks for having a second hand on this watch.

Durable and accurate
Love this watch. I've had it for a couple of months and it's put up with a reasonable amount of abuse so far, including underwater. It has just the right number of features for a lifestyle of moderate exercise and frequent public transit use, and I think it looks pretty slick as well. I took the advice in the instructions about synchronizing the analog and digital times, and I'm pleased (and surprised) to report that they're still perfectly in synch after the aforementioned couple months. Great buy.

good cheap watch
I've been wearing this watch for almost 4 years and haven't even put a battery in it. It's got everything I need and with 2 digital displays it's got a lot of info at a glance. I really like the auto-light feature. I'm totally sold on Casio now.
