With this non-stop, self-adjusting Casio Waveceptor timepiece, you don't have to worry about replacing batteries because it's solar powered and you'll have confidence of always knowing the correct time via the integrated atomic timekeeping technology. This stylish watch is suitable for both professional and casual wear, and it's complemented by a contemporary black resin strap. It includes a stopwatch function that can measure events down to 1/100 of a second for the first 60 minutes (and down to 1 second from 60 minutes to 100 hours), and it offers elapsed and split time modes, and 1st-2nd place times. Other timekeeping features include:

• World Time: 29 time zones (30 cities), city code display, daylight saving on/off
• 3 Daily Alarms
• Hourly Time Signal
• 12/24 Hour Formats

This timepiece also features an Auto Calendar (pre-programmed until the year 2039), ±15-second accuracy per month, Afterglow backlighting, and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving. This solar-powered watch has a battery life of up to 5 months on a full charge (without further exposure to light).

This multi-band radio-controlled watch receives a time calibration signal transmitted from several locations across the globe (the U.S. and Japan), and it has an auto receive function (up to 6 times per day). You can choose to automatically receive this signal four times a day, or manually update the watch to the atomic clock.

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

Best watch I have ever owned!!!
I'm normally not one to write product reviews, but I cannot say enough good things about this watch. In the past, I was a watch collector and rotated among wearing several watches depending upon my activity (work, sports, etc.) and mood (dress, casual, quirky). Since I purchased this watch several years ago on Amazon, I've pretty much abandoned my other watches and wear this one exclusively. It's comfortable, easy-to-read, and looks great for both business and casual wear. It's also the lowest maintenance watch I've ever owned. Because it's solar-powered, I've never had to mess with replacing the battery. And with its atomic clock capability, I've never had to mess with adjusting the time, especially when Daylight Savings Time rolls around. When my wife and I spent two weeks in England last fall, I kept the analog set to our "home" time and used the digital inset for UK time (it is easy to toggle between different time zones in digital mode). Finally, even after wearing it daily for several years, it still looks almost new. I thought I'd be turned off by the plastic band, but it has also turned out to be the most durable watchband I've ever owned. I sure don't miss having to replace batteries and watchbands! If I had to list any cons about this watch, it can be a little tricky to set, but that's mostly because I never have to mess with it and then have to dig out the small print instructions. I also don't use any of the advanced functions like the alarm or stopwatch. Otherwise, I've enjoyed this watch so much that I'm tempted to get a spare in case my trusty original ever wears out.

The Best Watch, PERIOD!!!
If you are interested in purchasing a Solar Powered Atomic Watch, then this is the watch of your dreams. I simply love this watch!!

Over the course of time, I have owned many watches, but this one by far is a keeper. I love it so much, that I am going to purchase another one as a backup.

I hadn't worn a watch for quite some time, so when I received my new watch, I accidentially bumped into the door latch as I was turning and put a scratch on the black outer coating of my new watch. I was very upset with myself, but it was my own fault. Low and behold after a few days, the scratch disappeared and is no longer visible. Apparently the outer epoxy type material helps keep the watch semi indestructable.

The accuracy is amazing, and once I reached HIGH on the battery charge, any normal light exposure (indoors or out) will keep the battery charged. Here is a tip for you, if you have a compact flourescent desk lamp, let the watch soak up all that light for about one to two hours. Once it reaches it's HIGH battery state, then you have absolutely no worries about ever losing battery power. Just make certain that you fully charge up the battery with as much light as possible until it reads HI on the display.

As far as comfort goes, the watch is very lightweight, and it's a joy to wear. Casio definately did a great job when they engineered the size, shape, look, and feel of this watch.

Bottom line, if you want to purchase a Solar Powered Atomic Watch, AND you want it to definately be a keeper for a vey long time, then invest in this watch. It took me about a two months of research to finally decide on this particular model, and boy am I glad I pulled the trigger and bought it.

I would easily give this watch TEN STARS, but unfortunately I am limited to FIVE STARS in this review. If you are on the fence like I was, JUST DO IT. You will be so glad you did.

Set up issue
Pretty watch. One minor annoyance. I cannot change the Japanese character that shows the day. No matter how much I try, I cannot get it done. The manual is not easy to follow.

After viewing the manual online, I followed the instructions, and managed to change the date from Japanese to English. After pressing and holding button A, press C until you see flashing date in Japanese. Then, press D to change it. As I said before, the manual is not easy. But, after many failed attempts you can figure it out.

September 2009

After using this watch over a year, I decided to leave my impression for future buyers.
No scratches on the display although I use the watch every day. the strap is still in good shape. Alarm sound is very short, yet it wakes me up. After getting used to all 4 buttons, the watch is easy to use. the battery is still full.

One complaint though! Each night the watch calibrates itself. The digital display is always correct. ( I have 2 atomic clocks at home). Several months ago, I noticed that the second hand was 2 seconds slow. No big deal. I followed the instructions. The second hand moved to 12 and stopped. Then, at the right moment, it started moving. I was really impressed.
Well, it happened again. The delay was 4 seconds this time.Followed the instructions. The second hand would move to 56th minute marker and stop! Basically, I couldn't adjust it. several nights i left the watch by window. It calibrated itself, except the second hand! Now, the digital clock always show the correct second movement. But the second hand is still 4 seconds slow.

I used to brag about Casio's calibration to friends. I wonder calling Casio's help line would solve the problem.
