Product Description

Amazon.com Product Description

Take it to the max with the shock-resistant, solar-powered Casio G-Shock men's digital sport watch (model G2310-1V), which offers a wealth of performance timing features and cutting edge technology. It features a 30-page databank that allows you to store phone numbers and other valuable contact information (8 characters for name and 12 characters for telephone number). For timing your sports training sessions, it offers a 1/100-second stopwatch with a 100-minute measuring capacity and elapsed time, split time, and 1st/2nd place time modes as well as a 24-hour countdown timer. It's also solar-powered--charging in either sunlight or indoor light--so you'll never have to deal with changing the battery. Light enters the watch through the sapphire crystal and dial, and hits a solar cell beneath the dial. Current is created and stored in the battery.

It has a durable black resin case with silver highlights and comfortable resin strap, and it will stand up to the rigors of recreational scuba diving, with water resistance to 200 meters (660 feet). Timekeeping features include four independent daily alarms (with one snooze alarm), an optional hourly time signal, world time from 29 time zones/27 cities, year/month/date/day display (with an autocalendar to the year 2039), and a battery power indicator. It also offers a scratch-resistant mineral crystal, and AfterGlow LED electro-luminescent backlight.

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.

4.0 out of 5 stars Casio G2310 - lots of functions, durable watch, October 31, 2004

By	N. J. Simicich "Gadget Geek" (Labelle, FL United States) - See all my reviews (REAL NAME)

This watch is a great little watch -

Time set from front panel only - no ability to set from WWV.

I have not had to reset it in the months I have owned it. It is yet to be a full second off - so far the watch has not slipped as far in time as my watch setting error.

12 hour or 24 hour time.

Default state - displays year, month, day, day of week, and status of rechargable battery.

World time state - displays the time in one of 31 time zones, including GMT. Each zone can be controlled for DST.

Data - holds a short alphameric pointer and a bt of data that uses the year, month, day, hour, minute, second - I use it for Ham call signs. Holds 30 items. Suitable for phone numbers, for example.

Alarm screen - the watch will remember five different alarms by day, month year, hour, minute, sec. It will alarm the same time and day every year or the same day every month or the same time every day - or just once, at a particular year, month, day, hour, minute, and second. There is a sixth screen where you set the hourly chime on or off.

Stopwatch screen: The stopwatch does splits and final time. It also does a "countdown" where it beeps three times and then a "go beep", optionally, if you are timing someone in something and they want an honest and accurate start.

Timer screen: The timer will do countdowns - either a single time or it will automatically repeat.

The face is a solar cell. It automatically recharges the battery. The watch can be put to sleep by holding adjust and mode - you won't get alarms or beeps in that mode, nor will you get a display - but the watch will keep time for much longer.

The backlight really works - in the old days, backlights on LCDs were miserable and then some of the watchmakers used tritium radioactive elements that were nicely lit but which you can't get anymore. Then there were some attempts at better pushbutton backlights - this is about the best I've seen. It is clear and you really can see the watch using it.

It works in one of two modes. One mode is that the watch backlight only engages when you push the button on the face - that's right, the easy to reach silver button on the front center of the watch lights it up.

The other way is to use the automatic feature - If you wear your watch on the outside of your left wrist, then IF it is not too bright and as you look at the watch the way most people do, by tilting your wrist toward you, the watch automatically lights up. This is essentially automatic - you look at your watch and it is lit up. This function is selectable - You might want to make it manual to save battery. I find it is too convenient to do without.

Despite the wonderful pressure ratings, unless you are very small, this watch is not suitable as a dive watch. The band won;t fit over a wet or dry suit. If you are doing warm water wimp diving in a skin or a shortie, you can use it - if you need to put it over a wet suit or a dry suit, the band is simply way too short. I know of no source for a band extender. Neither do the people at Casio. For short duration use, a wire tie or two will probably work.

What 20 bar rating means to me is that I could take it diving. Or, I could get it wet and not worry, even if the water is coming out of a hose with some force. The band means that I can't wear it where I need it - on the outside of my wetsuit or drysuit.

5.0 out of 5 stars Impressively Long Lasting, October 10, 2008

By	B. Day - See all my reviews (REAL NAME)

I bought this watch a few years back when I was doing heavy labor in a wet, hot and chemically intensive job. I never have to take it off except to shower. The hard rubber/plastic buffer keeps it from rubbing the buttons or face cover against anything that might scratch it. I have had this watch now about 3 years and it is very impressive still. A few minutes in the sun (even indirect light) and it is charged for days. My watch doesnt have any scratches on it and the lettering hasn't even faded! In the last 3 years, I have done construction, kitchen work, and home-remodeling from the ground up.

I love how the band is molded into a circle to assist in clasping, although it does make it a little bulky when you set it down somewhere, but that is so infrequent who cares? :)

I have a thing for time peices. I have 3 watches and 4 clocks (currently). This is by far the best watch I have EVER owned! If it had a digital compass I would consider this state-of-the-art.

I have even seen a documentary about the taining of Navy SEALs and one of the soldiers was wearing this watch! It is not jazzy for classy events but that's not what it is made for. This watch is strong and reliable enough for very rough treatment. Mine even holds up nicely to sub zero temperatures. It does tend to get a little uncomfortable when your wrist is at the edge of the desk when you type. The clasp digs in slightly. But I just take mine off when it becomes a bother.

Pros:
* Extremely durable and reliable
* Accurate
* Never needs a new battery
* Multifunctional, including 5 alarms and a countdown timer
* Wrist band designed to aid in the clasping
* Only needs seconds or minutes in natural sunlight to obtain a full charge
* Self-protective design
* Displays most-used information up front, while maintaining easy interface
* Many times pays for itself compared to those $10 walmart watches that last a few weeks or months.

CONS:
* Does not have a calculator or digital compass
* Not flashy or silver or full of bright colors for style
* Does not make your boss give you a raise :-P

5.0 out of 5 stars Can't beat it..., July 16, 2008

By	Andrew D. Flowers (Nashvega$, TN) - See all my reviews (REAL NAME)

Wife bought it for me several years ago and it is proving to be entirely accurate, durable, and functional.

Relatively easy to set and access features.

Solar is great and it runs without any need for maintenance (other than setting DST option).

Good size too, not ginormous or too small - pretty easy to read.

I'd buy another one if I somehow destroyed this one or lost it...
