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.

This review is from: Casio Men's G7900A-4 G-Shock Rescue Red Digital Sport Watch (Watch)

When I saw the cool red color of this watch i had to buy it...everyone should have at least one watch that is unique and stands out from the dreary black/white world of normal everyday watches...these G-Shock Casios (I have a few) are so rugged, extremely well built and reliable they will probably outlive us all. The only reason this gets 4 stars from me instead of 5 is that the initial set up is somewhat complicated and time consuming...whatever you do, DO NOT LOSE THE OWNER'S MANUAL!...you will need it!

5.0 out of 5 stars Debating between a Gulfman or G7900 or looking for a red G-Shock? The G7900A-4 is awesome!, February 10, 2011

This review is from: Casio Men's G7900A-4 G-Shock Rescue Red Digital Sport Watch (Watch)

I have been eye-ing the Casio G-Shocking Rescue Red G7900 for some quite time. Casio has released several colors of this G-Shock, one being a limited edition negative display of the red version, but other colors such as white, olive green, black, and another black but with yellow display.

But what caught my attention is the moon and tide graph. I have a Gulfman and G-Lide and the tide and moon display for the G7900 was one of the best I have seen out from Casio thus far. The display is nice and clear, not many obstructions as you get a circular moon tide graph on the upper left, tide graph on top and on the right, you get stop watch modes (for stopwatch 1 & 2). The larger display is the time and date.

Of course, aside from the cool display and what really pulled me in was its red color. The red bezel and band really pops and love the black highlights throughout the watch. Unlike other G-Shock red watches that have orange, this one is red and black and really enhances an outfit (especially if you were a lot of dark colors, especially black and blue). This watch definitely compliments an outfit.

As for the back case, it is stainless steel and you get the usual G-Shock Resist on the back.

The battery used for the G7900A-4 is one lithium battery (CR2025) which lasts approximately 2 years (normal usage). Accuracy at normal temperature is +/- 15 seconds a month.

Now, the band for the Rescue Red is also awesome looking! It doesn't have a shiny look but more of a matted resin look, which I like. The band is quite comfortable, but while not as perfect like the Mudman strap, it still fits comfortably on your wrist and at the base of the strap which connects to the case, there is a black guard that goes over the bumps of the band. Some people complained that watches with those ridges near the base hurt their wrist, so I felt that it was smart for Casio to include those black plastic guards on the back.

I. THE FUNCTIONS

The G-7900A-4 features the moon and tide display on top. Day indicator on top and at the bottom is the time, seconds and date.

Pressing the illumination button on the front gives you an aqua light which is the blue and blue/green illumination that many G-Shocks do come with. This G7900A-4 has two EL (electro-luminescent) panels that cause the entire display to glow for easy reading in the dark and also comes with an auto-light switch, if set, by a slight angle movement will make the light turn on. I have this turned off because I want my batteries to last long! You can set illumination from 3 to 5 seconds.

The modes that come with the Casio G-Shock Rescue Red G7900A-4 is:

* Timekeeping Mode
* Tide/Moon Data Mode
* Stopwatch Mode (ST1)
* Stopwatch Mode (ST2)
* Countdown Timer Mode
* Alarm Mode
* World Time Mode (48 Cities/29 Time Zones)

The stopwatch modes have a display range of 999 hours, 59 minutes, 59.99 seconds and there is auto-start. As for alarm mode, is good and audible. You can also mute the tones as well.

II. THE BUTTONS

The buttons are black and flat and not steel and have a feel similar to the Mudman's but of course, where the Mudman's are designed to keep mud out and takes much more pressure (and for some people, much harder to press), the buttons are easy to press on the G7900. There are four buttons and for the most part, one should not have problems with selections.

III. WATER RESISTANCE

The Casio G-Shock Rescue Red G7900A-4 is marked at 20 Bar which means and this means you can go scuba diving and snorkeling with it.

IV. TIME & MOON GRAPH DISPLAY

The Casio G-Shock Rescue Red G7900A-4 features a circular moon graph on the top left of the display. The moon phase indicator indicates the current phases of the moon as viewed at noon from a position in the Northern Hemisphere looking south. The watch performs a rough calculation of the current moon age from day 0 of the moon age cycle and the margin of error of the displayed moon age is +/- 1 day.

The tide graph has six graphic segments, each of which indicates tide level. The tide graph displayed on the watch is based on the current moon age. The greater the error in a particular moon age, the greater the error in the resulting tide graph.

IV. OVERALL

I absolutely love this watch! It scores high on style (looks great if you wear a lot of black or darker clothing), high on comfort and the display, is stylishly cool, especially if you are looking for a larger tide display on a chunkier watch. The functions are awesome and you really get a lot for your money for the 7900 (I paid $64.99 during the holidaysfor the Rescue Red but they typically sell for under $90) and you can often find various versions on sale on Amazon by Amazon or third party fulfilled by Amazon as well.

It's important to note that some people have received their G7900's in the tin G-Shock cases, I did not. Mine came in a black standard G-Shock cardboard box. The manual as usual with Casio G-Shock releases are quite thick, especially for this watch.

There is really nothing negative that can be said about this watch. It's simple to set (if you are used to G-Shocks), otherwise you get a nice thick manual in various languages to peruse. The watch looks great, it is comfortable and Casio went all out in making sure that those who care about moon and tide displays get a cool watch. Also, the fact that you get the guards on the base of the straps is a plus. I have to say that while the Gulfman was created for the sea and has a pretty cool tide display, I prefer the Rescue Red over the Casio Gulfman in terms of aesthetics and also, it's a 20 bar watch, so you can go deep sea diving with it.

I do recommend purchasing Vinylex Quick Wipes (or spray) to keep your G-Shocks protected (since Resin does tend to harden or crack if not cared for).

But in the end, I have to give the Casio G-Shock Rescue Red G7900A-4 a pretty solid rating. For those looking for a red G-Shock, this is the best out there in my opinion. It's not too flash, it's stylish and cool. But most importantly, it has a lot of the features that make it a pretty awesome G-Shock.

Highly recommended!

This review is from: Casio Men's G7900A-4 G-Shock Rescue Red Digital Sport Watch (Watch)

Long week waiting on watch-amazon direct is faster. So far the watch lives up to the hype-does what it is suppose to do.Functions don't seem too complicated to set-instructions are easy to read and follow-but I must admit I have yet too set the tide function and the lunar-at age 49 I am in no hurry. The black g-shock rescue watch feedback on this site has a very good instruction guide for tide and lunar so that should be no problem.
I like this watch...Will update on long term experience.
