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.

5.0 out of 5 stars had it for a month, has hardly left my wrist, April 24, 2007

This watch does exactly what I want it to, tell me the exact time no matter where I am in the world. It is supposed to pick up the time signal in Europe, England, Japan, and America, but I have only tested the first two so far and it works fine. It features multiple (30 I think) time zones, including some +30 minute zones. There is no GMT zone, but I turned daylight saving time off for LISBON and use that in place of GMT. It has 5 alarms, which is 3 or 4 more than I can use, but nice to know they're there if I need them. Countdown timer only goes up to 59:59, I'd like to have one that counts longer than one hour.

As for the solar power and legendary G-shock toughness, only time will tell.

When I got this watch, it came on within a second of being exposed to light and all I had to do was set the time zone and I was ready to go with the exact and correct time. So far I'm very pleased with it and consider it essential travel gear.

Update: After having worn this for a few months, I'm still very happy with it. One thing I noticed was that outside the range of the atomic clock signal, it lost about 5 seconds a month.

5.0 out of 5 stars A Must Buy!, January 14, 2009

This review is from: Casio Men's GW800-1VCF G-Shock Atomic Multi-Band Watch (Watch)

GREAT! Much smaller fit than the GW500A-1V which I also own. But still

a big "manly fit" but in comparison to the GW500A-1V it is not as thick. It just seemed to me as much as I like the GW500A-1V it had some useless features like the three circles at the top that are really unreadable & uses battery power (which made the watch go into the "recovery state" at times).

Now to this Model : The big selling point of this watch GW800-1V for me is it has a Countdown Timer. Most Casio Watches I see don't have a Countdown Timer (countdown from a hour only). I use this feature 3 times daily.

Trying to get a back-up band (Black Resin) has been a problem . . . . Casio has these on back order (so far a month).

A update band came in the next day. Ordered from Casio Sales & Services out of California. Note the band looks like it will be harder to replace myself than other Casio Bands (which I have replaced myself) but will not know this until I have to do it; which I trust will be many years away (or never). Also note the buckle on the band has two "prongs" going into two hole on the band which is not typical of most bands; the look takes a little getting used too, but I did after a few days. It is a band that I feel can only be replaced with the Casio Band for this model a "universal/generic" band I feel would be hard to find, but have not tryed looking & no need too because I have the Casio Band now.

This model the Atomic checks at 12 midnight,1,2,3,4am. Once it gets a

sucessful Atomic check (in a 24 hour period) it will not keep checking each of the other times. I like this because it saves the battery. Even though it has a Solar function I found that doing anything you can to conserve battery useage like light not being pushed is helpful so the watch will not go into the "recovery state". Also to make sure the watch is in bright light at least 30 minutes a day is helpful as well.

Besides all the many other features this watch has (which you can read up on) in general the word from me is this watch is a must have! It has not been off my wrist since 12/08/08 (easy to clean while in the shower)!! Trust my comments have been helpful to you and you order this model & enjoy the many features of this fine timepiece!!!

Another update like the watch so much I bought a 2nd watch on 2.13.09. So I have a back-up. Also I have 3 boys by haveing two GW500A-1V and two of this model GW800-1V I can pass them on to my sons when they are teens/young adults (their wrist have to be able to handle the size of these watches first). So need I say any more my first recomendation is to go with this model GW800-1V, don't delay your ordering you will be very happy to have bought this "workhorse" of a watch!!!!

5.0 out of 5 stars Accurate Sports Watch, January 10, 2009

This review is from: Casio Men's GW800-1VCF G-Shock Atomic Multi-Band Watch (Watch)

I've worn the GW800 daily for 3 years and have no complaints. It syncs nightly to an atomic clock as advertised as long as I leave it on a windowsill at night. It is the most accurate watch I've owned. No problems with the solar charging and submerging it in water is not an issue. This watch makes better use of screen real estate than other watches I've owned, i.e. minimum of redundant circles and status bars counting seconds. The numbers are easy to read. The simple uncluttered display was the main reason I chose the GW800 over other atomic multi-band G-shocks. Otherwise it has all the features one would expect from a Casio digital: stopwatch, 12/24hr time, backlight, etc. It has a few added useful features such as secondary timezone and 60-minute countdown. While it is a bit of extra effort to set it by a window at night it has otherwise been hands-off after the initial setup. The size is smaller than the gigantic classic G-shocks but larger than the tiny 80s-style classic Casios. Small for a G-shock but normal-size by men's watch standards. It is a nice-looking digital but if you wear a suit to the office the metal-band version would be more appropriate.

As far as the solar timekeeping, it can be hit-or-miss at times. Occasionally the watch doesn't sync for a day or two, especially around twice-yearly time changes. Location seems to matter. East-facing windows are better than west windows. I've never been able to manually sync it during the day. The timekeeping is still very accurate and eventually it always syncs so it hasn't been a problem. I bought a backup watch because I read reviews about the solar batteries losing their charges and dying prematurely. After three years this has not been a problem and the backup watch sits in a drawer unused. Some people complain that Casio alarms are too quiet but I can't comment on that as I use my cell phone's alarm to wake up. My only complaint is that the GW800 works so well it's boring. No setting, no adjustment, no battery changes. Nothing to do but wear it and observe precise timekeeping.
