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 Best looking watch I've ever owned., July 20, 2010

This review is from: Casio Men's GA100A-7 G-Shock X-Large Analog-Digital White and Blue Sports Watch (Watch)

After a lifetime of black or metal scuba and combat style watches I decided to give this model a try.

This is hands down the nicest looking watch I've ever owned, very classy.

First time I wore it to the gym, I could tell it was noticed and it's been complemented several times during day wear.

I was worried that white would look girlish... this thing looks as girlish as an M1 Abrams battle tank camouflaged white for the winter snow.

The blue numbering and hands look great on the white background and are soothing on the eyes.

The wide double-holed band adds to it's muscularity.

I'm a big guy with a large wrist and am only two notches to the end of the strap, so if you have a monster wrist you may be disappointed.

On the other hand, my petite girlfriend tried it on an it looked amazing on her and the band was could be adjusted to fit her her perfectly, so I'm ordering one for her also.

I've also got white skin since I'm not a big fan of sun exposure and it still stands out, if you have a darker complexion this watch will really pop.

And for such a big watch, it's very light.

One note of caution, for what I've read long sleeve darkly dyed cotton shirts will stain this watch as well as if you rub it against blue jeans.

The finish is glossy, not matte so normal dirt wipes right off.

The time keeping is very accurate and the other functions like stopwatch, alarm and countdown time, etc. are a bonus.

I've owned several of Casio watches and have never had one that wasn't accurate.

As a gift or for yourself even if you're a girl this watch will not disappoint.

4.0 out of 5 stars Beautiful Watch; bad lighting., November 11, 2010

This review is from: Casio Men's GA100-1A4 G-Shock X-Large Analog-Digital Black Dial Sports Watch (Watch)

I'll start with the positives:

It's straight-up BEAUTIFUL. This is my first watch purchase that was above the $25 Wal-Mart threshold and I don't regret it for a second. I'm in love with its engineering beauty and its durable materials. The features are great (even if I don't plan on using the extra two dials). The face of the watch is exactly as described: X Large. It dwarfs my old geeky calculator watch, and I feel like I'm wearing a behemoth on my little wrist. The red and black provide a rather appealing contrast and I'm glad I purchased this over the all-black model. I'm sure it'll be attracting a lot of looks once I go back into schooling.

Now for the bad:
The LED Backlight is TERRIBLE. One pro my old watches had: a blue LED backlight option. It illuminated the entire display and checking the time was no problem.
This watch however, uses a yellow LED lighting option, and the lighting shines from the bottom of the display, thus causing shadowing all throughout the interior. This makes the digital display difficult to read (and I personally HATE yellow lighting), so you have to depend on mostly the analog hands in dark situations.

Overall: If the lighting con does not bother you, this watch is a solid purchase.
From a past reviewer it seems the White option is a little better for low-light situations, and it's obvious the Black model is great for low-lighting with its white digits in front of a black background.

3.0 out of 5 stars Do not buy from AYW Watches LLC -Jakes Watches!!!, August 8, 2011

This review is from: Casio Men's GA100-1A4 G-Shock X-Large Analog-Digital Black Dial Sports Watch (Watch)

I ordered Gshock GA 100-1A4 as a gift for my wedding anniversary.I had searched high and low for this particular model and then decided to buy through Amazon.I was really excited to receive this watch on the estimated delivery date.Imagine my disappointment for all the preparation I had done for this when I received a totally different watch!!!

So I had placed a nagative feedback on the seller,AYW Watches LLC -Jakes Watches(third party seller).Three weeks back,I received a very unapologetic mail from Jakes Watches saying that Amazon had fulfilled this wrongly and belittled this by calling this a small mistake due to a small digit.As a service recovery,the seller promised me a refund for the blunder done!I was asked to remove the negative feedback by the seller. It has been 2 weeks since the seller has claimed to have sent the refund, I still havent received it. The seller does not even respond to my mails now. This is cheating!
When I called up Amazon customer service, they conveniently washed off their hands saying it was an amazon product and the service recovery was not promised by Amazon and they gave me the most inconvenient promotion.
My husband loves the watch but this experience has totally stopped me from buying anything though Amazon and especially Jakes Watches.

Beware of Jakes Watches!!!!
