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.

Customer Reviews

Great watch!
I received this watch today. Thank you Amazon for fast shipping (lousy packing, but the neither watch box nor watch itself was hurt).

Perfectly comfortable. Easy instructions. Great functionality.

All-around delighted by this great looking timepiece.

I've been wearing it and playing with it since it arrived about 5 hours ago (I should have spent more time actually working...), and having gone through all the functions and settings, I have found no (ZERO) negatives.

Highest recommendations.

Update... Day 2.

I wore the watch all day yesterday and forced a synch with the atomic clock at 6:39 PM. It worked flawlessly and caught a 'L3' signal even in the hills where I live.

Last night I put it on my desk and at 12:04 this morning it re-synched automatically.

This is a truly outstanding watch. I am wearing it again this morning and probably will all weekend. BTW... this kind of watch is usually not my style. I have worn mechanical Swiss watches for years; mostly automatics. This is my 3rd G-Shock and is my favorite by leaps and bounds.

Great watch.

Update...

After a little over 2 weeks I can say that this is the best digital watch I've ever owned. It rarely leaves my wrist. I wear it to work, the gym, hiking... everywhere.

When I don't feel it necessary to put on a 'dress' watch, this is what I wear.

The buttons are easy to push. The dial is easy to read. It's incredibly functional... and great looking!

Again, the absolute highest recommendations.

Titanium G-Shock Solar Powered Watch
Casio's G-Shock Titanium Solar Powered Watch is amazing so far. Lightweight, radio wave controlled time (for even greater accuracy), the battery recharges on it's own through solar polar & indoor lighting; overall, the features that come with this watch might not have everything that a 1k watch would, but what it does contain has outstanding performance. I have had this watch only for a month now but years from now I'm sure I will still be impressed by this watch. When the time changed, the time automatically adjusted for daylight savings - that's news to me.
Comfort - 7/10 'the band that comes with the watch isn't too comfortable but the watch is lightweight. With a Velcro band the watch wears a lot more comfortable.
Style - 9/10 'for the outdoor use, great look; it's a little thick though.
Technology - 10/10 'of the features the watch contains, everything seems almost flawless. User can enable auto-backlight, 5 alarms, worldwide timezone settings, of course the G-Shock feature, etc.
Price - 6/10 'the price paid for this watch was around $180. It is neat and I'm sure the cost will pay for itself down the road, but for the features, I think it could be a little bit lower (~$120)

If you're looking for a great watch that is going to withstand the outdoor heat/cold/dirt/water/hard hits, this watch (as long as any Casio G-Shock watch) is perfect for you. They have many styles and features; just pick which one that suits you most.

Outstanding Watch!
This is a large, good looking, solar-atomic watch. The Casio Waveceptor body is titanium so it will be light as air on your wrist. You can wear this precision instrument without fear of breaking it. Excellent construction. This baby is built to last.

The feature I like best is when fully charged, it will run for about 9 months without additional exposure to sunlight. The other solar watches I researched all required almost daily sun exposure or you face the proposition of early battery failure.

With the additional benefit of owning an atomic watch, you will enjoy superb time accuracy. Try it - you'll like it! Two thumbs up.
