The G-Shock Story

G-Shock - Absolute Toughness

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.

Casio’s G-Shock line was created on just such a directive: to build a watch that never breaks. And in 1983, this product was developed to shatter the notion that a watch is simply a fragile piece of jewelry that needs to be handled with care.

G-Shock is renowned as the world’s toughest watch and is in the midst of a huge renaissance since its 25th anniversary celebration last year. It is the best trending watch brand in the industry right now and thanks to its toughness and durability as well as it’s cutting-edge technology, it is among the best values in not only timekeeping but all personal accessories.

In addition to toughness, 200 meter resistance and fantastic cutting edge and hip styling some G-shocks also have such technology as Tough Solar Power for battery life of 20-30 years (great for our planet), Atomic timekeeping for the more precise time available on earth as well as unique features like moon phase and tide graphs.

G-Shocks come in a variety of styles including Rubber/Resin bands, Solid Stainless Steel and even Titanium.

Since it’s launch, Casio’s G-Shock continues to evolve and push the envelope. The non-stop, self-adjusting (solar-powered atomic-timekeeping) G-Shocks featured in the Amazon.com assortment are the latest, greatest example of this evolution!

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.

5.0 out of 5 stars Form, function and a movement found in a watch that costs three times as much., June 14, 2009

By	Cameron R. Settle "CaminDFW" (Little Elm, TX United States) - See all my reviews (REAL NAME)

--- Warning: Long, opinionated review ahead ---

I could go on and on about how many watches I own (40+), I could list off the caliber of watches I have (Jaeger-LeCoultre, two Rolexes, Zeneth, Franck Muller)... but what I do want to go on about is my love of this Giez watch.

I have many watches (see above) and many of them are the various models of Casios which have been released over the years; from the first pathfinder watch to the current Riseman. The Giez GS1100 is by far one of my favorites. Reason - Form, Function and a wondrous movement.

Form - Simple and clean at first glance, then as you look closer the detail comes to light.

Function - it does what it should do. It is one of the most accurate timepieces on the planet. On the most basic of levels, it tells time, has a stop watch, one daily alarm, day and date. For those who need it; it has world time mode and it (the watch) supports the National Institute of Standards and Technology reception standards for the US as well as those for Japan, The UK and Europe.

Here is a little, how shall we say... commentary:

The watch is fluid, it has a gear driven movement (the same as the $900 Oceanus line by Casio). It should be looked upon not as a digital watch but as a precision time keeping instrument. The few reviewers whom complained about the movment taking forever; stop playing with your watch, it's not a toy. Set it and know that it works. As an aside, if you are a global jet setter and you need to change the world time city, press the mode button and then immediatly hit the reset/advance button; it will advance the second hand/city indicator with out having to wait for the current setting to queue up.

The other complaint about reception, I have no comment other than "Please know that it is a low power radio wave which the watch is receiving. If you live in a basement or a structure which is not "wave friendly", please know that when your watch does pickup the signal that it is not like it is going to lose that much in accuracy before it's next acquisition (unlike my Texas Timex.. Rolex Air King, which can and does).

My only complaints about the watch are very minor: I wish it had an hourly chime and I also wish the alarm was louder.

In conclusion - If you like Casio watches and you have a modocum of patience; you will not be dissapointed with your purchase.

5.0 out of 5 stars Uber Time Piece, April 7, 2008

By	D. Adkins "Chance Favors the Prepared Mind" (On the move) - See all my reviews (REAL NAME)

Top quality watch! Full feature set with the added bonus of Solar and Atomic clock sync'ing. The build is very good and I really like the well thought out style of the watch. It does so much so well it moved me to write a review - which I very rarely do. It seems to be the perfect Expedition watch - a rugged and accurate instrument.

5.0 out of 5 stars Casio Men's G-Shock Geiz Series Multi-Band Solar Atomic Watch, December 2, 2008

By	S. J. Schoenewald "Defensor" (Williamstown, NJ USA) - See all my reviews (REAL NAME)

Way to go Casio! This is the watch I have been wanting for a long time. Should have bought one sooner. It was easy to set up and now I don't have to worry about batteries and not having the right time and date. Since receiving this watch, I checked the time several times a day against another verified source, to see if the watch was keeping the right time. I now trust the time indicated as true. Was worth every dollar I paid. I highly recommend this watch to anyone needing a "set and forget it" new watch or replacement.
