Amazon.com Product Description
A stylish, sporty timepiece, this Casio casual men's watch keeps you in touch with Mother Nature thanks to integrated moon phase data and tide graphs. The aluminum watch case measures 40mm wide (1.57 inches), and it's complemented by a tapered black resin sport strap. It includes a stopwatch that can time events down to 1/100 of a second, and features a 100-hour capacity, split time, and 1st-2nd place times, as well as a countdown timer with a 60-minute capacity. Other timekeeping features include four daily alarms (with one snooze alarm), dual time, hourly time signal (which can be turned off), and 12/24-hour formats. This watch also offers a ±30-second accuracy per month, Afterglow backlighting, Auto Calendar (pre-programmed until the year 2039), and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving. It has a battery life of up to 10 years.

Development of the Timepiece Business
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.

Customer Reviews

Great Value
Pro's:
1. 5 alarms with one of them having a snooze option.
2. Moon Phase and Tide forcasting, you can advance to dates in the future on the moon screen and can view the tides of that day (I can predict the tide on a specific future date).
3. You don't need to hit any buttons to determine the current tide/moon phase.
4. Countdown timer, some casio's do not have this option, but this one does.
5. Dual Time Zone.
6. Sun Compass (show you an angle and you line the sun up with the angle and you can determine where North is). Each dot/mark on the watch is 6 degrees.
7. Every screen but the stopwatch show the current time.
8. Stopwatch has split times (however not reviewable - see cons)
9. Band is very comfortable with a strong buckle and is not bulky.
10. Pretty good instructions, good detail, shows the options.
11. The Price is great, other comparable watches (with good brand names) with these options run around $60.


Con's:
1. I wish the booklet or a website provided the lunitidal interval for most beaches as this value slightly differs from location to location. The Lunitidal Interval is a delay between the moon at the middle of its rise/set and the following High tide. It is needed for the watch to display accurate tides.
2. The countdown timer can only be set to minutes. I can set it to count down from one minute, but I can not set it to count down from 20 seconds.
3. The band where it connects to the watch body cannot rotate past a certain point. This means that it is always in a circular arrangement and not as comfotable as it could be in a pocket. It can not be flattened
4. I wish the light was an indigo light instead of the bulb light.
5. I wish the lens was a little better protected by the outer rim. I hate scratches (no watch is perfect in this regard).
6. The indicator that shows if the alarm is armed is a little difficult to see - but it can be seen.
7. Seems to be about 4 fast after a month.

My con's are more a bit of whining. I love this watch. I purchased this watch for a specific purpose, but now I wear it all the time. Great look, very comfortable, very useful.

Nice cheap watch
I own a lot of watches (something like 50 and I wear 20 of them actively.) I bought this watch as a vacation watch (I break it or lose it, it's okay.) I liked the phases of the moon and tide feature. However, in reality those features don't work so well. The Phases of the Moon works okay except the display is hard to read. The tide requires longitude, latitude and tidiludinal (or some such) setting that requires a $2.99 purchase at some surfer site for each beach you might want to visit. So, that feature is useless. The watch itself is less comfortable than other Casio and Timex plastic watches and it has a "bad plastic" smell to it that hasn't gone away. The back light is weak. The multi timezone feature is useless. For $17, it's not a bad deal, but if you've got a larger budget (say, $30 or $40) spring for a better watch, even if it's got fewer features.

No major complaints
I bought this watch because i was going to the rainforests of africa for 3 months and needed an initial timekeep while i was in the capitol city but figured it wouldnt b as important in the rainforrest and would probably get really messed up, so i didnt want to spend alot of money on the watch. I did abuse the crap out of my watch but by the end of the trip it proved to work very well and a very good deal for under 25 dollars, i wanted to keep the watch but instead gave it away to an african friend of mine as a gift, im planning on buying another one because it was a great watch, very durable, no worries about getting it soaked/hitting it over a tree accidently/dropping it off a small cliff by accident (granted it did fall on leaves)... and the tide feature was nice when i was by the ocean, i didnt think it would work (or that the tides would b somewhat diff where i was) but it proved to be true and allowed me to know if i can leave town and get back on time or would the roads be flooded due to high tide and id have to go for a swim for a nice distance... reliable, sturdy, (NOT very big like some guy compared it to G-Shock, thats just silly, its nothing that size) and dont look half bad, plus the alarm always woke me up on time (im typically a hard sleeper) and the light feature allowed me to see the time even in a dark tent... my only complaint was that u would have to keep hitting the light button after every other button u press in order to get it back on (light turns off as soon as other button is hit), so if i was setting my alarm in my dark tent i would have to set it one digit at a time making sure to hit the light every digit imbetween... but its completely doable and would not stop me from buying it again in the future... also stop watch and count down timer proved to be excellent for field research
