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.

The perfect watch for the technophile who wouldn't be caught dead with a digital watch,
By S M "firepepper red" (California, USA) - See all my reviews
This review is from: Casio Men's EFA120D-1AV Ana-Digi Edifice Thermometer Bracelet Watch (Watch)
Although this watch is "only" a Casio it is simply an amazing and elegant timepiece. For under $60 dollars the watch looks like it costs at least $100 more and has tons of features to keep any technophile content.
The Pros of this watch include: - Looks: Unlike a lot of other Casio watches, which have cheap looking plastic parts holding the metal pieces together, this watch is all metal. It looks like it is on par with the Seiko's and Pulsar's out there. I chose the square model over the otherwise identical round model because it looks more elegant whereas the round appears more sporty... either way you cannot go wrong. - Features: The face of the watch is embedded with digital screens that are not normally visible unless you really try and look for them. This allows it to have the grace of a analog watch with the technology and features of a digital. But remember this is an analog watch first so the digital screens are not quick and easy to read like a true digital watch... they are there for supplementary information. Cons of this watch include: - The hands of the watch can partially obstruct the digital screens at times. - The indicators for the alarm, hourly chime, autobacklight, etc. are really small and hard to see. - The clasp of the band is made from much cheaper looking steel than the rest of the watch. This is not really a problem since you cannot see this part once the clasp is closed. - The band is rather difficult to adjust and there are not a lot of settings in between so I was not able to get the "perfect" fit although it is very close. - The band seems to scratch easily. I have had a Pulsar diver's watch for 20 years and had no scratches on its band. I have owned the Casio for less than 1 month and already there are a few faint scratches. Luckily I have not scratched the crystal as of yet but I would not be surprised if this also was easy to scratch. - The thermometer is innacurate but it can be calibrated and once you calibrate it according to your body temp it does a fair job of telling you the temperature. - It only has 1 alarm, and it does not have atomic timekeeping like other Casio watches. Overall I have been really happy with the features and appearance of this watch. It really draws lots of compliments for its analog style and when people look at it upclose they are wowed by the technology factor as well. Really a good buy for the money, hopefully it will hold up with daily use and abuse.

I'm wearing it right now! (Updated),
By
Amazon Verified Purchase(What's this?)
This review is from: Casio Men's EFA120D-1AV Ana-Digi Edifice Thermometer Bracelet Watch (Watch)
Pros: It's digital and analog. It looks decent; slightly dressy; a change of pace for me since I usually buy sports watches. It's got a thermometer. World time. It's less than $60.00!! For value, it's a five star!
Cons: Backlight is not very bright and does not stay on long. It's not atomic (I usually buy waveceptors). The digital part of the watch is round (within the square) I'd rather the whole square but that's my own opinion. It's a little bulky for others but I'm used to bulky watches. Battery life rated to only last two years. Buy the link remover tool Heavy Duty Watch Band Tool Link Pin Remover for Bracelet Adjustments Watch Sizing Repair Fix with TWO (2) EXTRA PINS if your wrists are smaller than average unless you like loose watch bands. I bought the one I just listed and it works well; just be patient. You really can't beat the Amazon prices compared to most retail shops! Update: April 2008 and a control push button came off! Dissapointing to say the least.

A decent+fashion full-metal watch,
Amazon Verified Purchase(What's this?)
This review is from: Casio Men's EFA120D-1AV Ana-Digi Edifice Thermometer Bracelet Watch (Watch)
This watch fits men with regular or bit smaller size wrist. The black dial plate, full stainless steel barrel shape make it looks decent but fashion. CASIO has another model with round shape, but I think the barrel shape looks more fashion. The size of this watch is on average, but a bit bigger would make it perfect. The thickness is just right.
The ED light is dim, however it doesn't bother a lot since you'll also want to save the battery power. The thermometer is interesting and useful. Putting the watch and other thermometer together into water would help you set the point right if you need to. The only thing I'm not satisfied is the adjustment of the wrist band. The segment doesn't fit the best for me, which my previous SEIKO perfectly did. You won't regret buying this watch with this price. (<$60)
