The Waveceptor Story

Waveceptor- On time all the time

With the launch of its first watch in 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. Armed with cutting-edge technology developed for pocket calculators, Casio entered the field confident it could develop timepieces that would push watch technology forward.

With Casio’s Waveceptor Line Casio is focusing its efforts on radio-controlled watches: the radio-controlled or Atomic 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. All Waveceptor watches even automatically adjust for daylight saving time…now that is an intelligent timepiece.

Some Waveceptors even feature a built-in solar battery which eliminates the nuisance and waste 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. Amazon.com offers the largest online assortment of Casio Waveceptors

Waveceptors are everything you like in a fine timepiece, easy on the eyes, easy to use and provide the most precise time on planet earth. With a Waveceptor you come only be fashionably on time…all the time.

The Casio Story

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

3 Years & Running Strong
I bought this watch in Akihabara in 2005 when it was not available over here. What attracted me were the large clear numbers. These days, I let it set itself to the atomic clock at NIST in Colorado over night about once a month. It starts searching about midnight and is usually synched about 5 minutes later. Nothing else has been needed. The bans fits and has held up well. The battery still shows "H" after 3 years. I presume this is because the solar cell powers it most of the time. Though I hardly ever use the light. The crystal is hardy, as well. Couple of scratches around the edges. I do take it off before heavy work in the yard, but that's about it. One problem I had was the instructions were in Kanji! My Kanji is not so good. Better hold on to the instructions because there are a lot of functions and not many buttons. The dual time zone feature is very helpful when flying. No GPS, compass, or 1,000-name memory. It is just a solid time piece.

Great digital watch
I compared both the WV300DA-7B with the WV300DA-7A, the only difference being the negative display versus the positive display (negative is the 7B, and positive is the 7A). I eventually decided on the 7A, since the display was easier to see, and the light was more effective in the dark. This review is based on the 7A watch.

I was interested in finding a watch for my dad that was solar powered and had 24 hour time, since he needed 24 hour time for work. This meant that it had to be a digital watch, and Casio is pretty much the only company that has digital solar watches. Most of Casio's G-Shock and Wave Ceptor watches look pretty ugly and bulky but this one is definitely an exception. It has a slim profile with a rectangular case.

Contrary to what one of the reviewers said, I thought it as pretty easy to setup. I didn't need the manual to figure out how to change the city, or the DST setting, or the time. The back of the watch has engravings to state what each button does but you can figure it out by trying them. I used a thumb tack to remove the links to resize the band to fit my small wrists. You just have to force the holes opposite the arrow direction to unlock the links and perform the reverse to lock them. It took a little bit of effort to remove one, but once you get one unlocked, the rest are easier since you know much effort it takes.

It uses a Panasonic CTL1616 Cobalt Titanium Lithium battery for the storage, whatever that means. If it dies, just replace the battery. I'm not sure how long the rechargeable battery lasts but it should last a while.

Casio WV300DA-7A stainless
High end, stainless steel, digital watch with large, easy-to-read, black letters on white background. Casio design has reduced thickness of the atomic watch so that it now fits under the shirt cuff.

I wear the watch to bed at night and it receives the radio time signal while I sleep. The extensive instructions about watch placement to receive WWV radio signals have not been needed for my Ohio location.

Sizing of the watch band required the services of a watch repairman - but he did it no charge.

Many easy-to-use features.
