Amazon.com Product Description
Sleek and modern, this analog-digital combination timepiece from Casio's Waveceptor series helps keep you on track all day, every day, for business or pleasure. Using atomic timekeeping, the watch receives official radio signals that keep the displayed time accurate, with world time settings for up to 29 time zones (30 cities). The time displays on the elegant black dial, with Art-Deco-inspired silver-toned hands highlighted by red, silver-toned bar and triangle hour markers, and dash and Arabic numeral indexes for easy 24-hour conversion. A rectangular digital window at six o'clock automatically displays the day, date and month and is pre-programmed for accuracy through 2099. Silver-toned Arabic numeral indexes with black backgrounds highlight the stainless steel bezel. The black band is made of a durable resin and comes with a buckle clasp. This watch also features four daily alarms and one snooze alarm, a time recorder function, and a 1/100 second stopwatch function. Water resistant up to 165 feet, this watch offers a two-year battery life and is backed by a 1-year limited manufacturer's warranty.

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

Great features but very fragile
I've had two of these and each has lasted less than a year. On both of them the case broke at one corner where the band attaches. I paid $40 to replace the first (the case and band are explicitly excluded from the warranty) and the new one just broke after just a few months. It basically fell off in my lap and on examining it, I notice that a second corner is also cracked. I'm not aware of subjecting these to any unusual stress. None of my other Casio watches has ever failed in this way, even after 10 years or more of rougher service so I think there is something unusually weak about the case material on these.

Disappointment
This is a great looking watch with great features. Too bad it only lasted seven months. The manual states that the battery will last two years under normal use conditions. The battery lasted seven months. The manual also states "never try to open the case or remove its back cover". Casio insists that you have the battery replaced by one of their authorized service centers. There are only two or three in the USA according to their website. I took it to a local jeweler. The watch never worked properly after the battery was replaced. The time calibration receive function worked intermittently and the analog time would not synchronize with the digital time. I can not recommend this watch. My next watch will be another Timex.

Great watch, bad strap design
I've now owned two of these Waveceptor watches. Functionally they've been teriffic. Good looks, atomic time synch feature has worked flawlessly. Unfortunately the case cracked on both right where the "pin" connects the band to the watch. This cannot be fixed. As noted by another reviewer, this is a fundemental design flaw that Casio seems unwilling to address. I got about 18 months of service from each before they broke. At $45 each, you can almost rationalize it as a disposable (but not quite!)
