Product Description

Amazon.com Product Description

Stylish enough for the boardroom but rugged enough for the wakeboard, the Casio Marine stainless steel analog-digital watch for men (model AMW320D-9EV) combines the timeless look of an analog watch with the functionality of a digital watch. This analog digital combination allows you to see up to 2 times or the date with day of the week. The round silver stainless steel case measures 40mm wide, and it's complemented by a black resin sports strap. The inner rim of the bezel provides an Arabic numeral readout with small minute indexes, and the gold face includes luminous hour markers, oversized luminous hands (with seconds hand), and a digital window above the 6 o'clock mark.

Timekeeping features include dual time, a daily alarm, auto calendar, and a 1/100-second stopwatch with a 24-hour capacity. Other features include a ±30-second accuracy per month, scratch-resistant mineral crystal, and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving.

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.

5.0 out of 5 stars Mine just died, January 27, 2005

By	Randall Black (Irvine, CA USA) - See all my reviews (REAL NAME)

After about seven years of great service, my wrist now bears a dead AMW320D (great name, eh, really trips off the tongue). I went in for my third battery replacement and the jeweler told me that corrosion had eaten away at the movement. The first time I replaced the battery I learned that the seal had to be broken and the watch might no longer resist water. The soft rubbery plastic strap died long ago, replaced by a superior twist-o-flex-style metal wrist band.
Now you might think I'm dissatisfied. But I intend to order another the minute (or so -- I don't have a working watch) I finish writing this review. Why? It has been a great watch. Analog plus digital gives me easy-to-read intuitive time checking, along with all the bells and whistles of silicon: multiple times, alarm, stop watch, and calendar. The outer ring on the face lets me rotate the "north" arrow to a future time, say 45 minutes from now, and I know time's up when the minute hand gets there. (I have no idea why the face ring has compass points and degrees marked on it -- to fool one's friends?) The watch has been rugged, holding up to the shock of using hoes and axes, although I didn't push my luck if I remembered to take it off.
I'm looking at my old friend, now motionless and blank, and figure he had a pretty good run. Time's up for this timepiece, at a cost of a little more than $10 per year. Since I bought the last one on display at Mervyn's, I didn't get a box or manual and didn't even know what it was called AMW320D until looking it up on the web just now. AMW320D I didn't even know your name all these great years together.

5.0 out of 5 stars Best of both watch worlds, December 24, 2004

By	Pimentón (Pasto Azul) - See all my reviews

This Marine Gear has become one of my favorite watches of all time. And take this from an enthousiastic collector who's tried out quite a few watches. If you're like me, you might like to alternate at times between analog and digital watches. I find myself using an analog watch about 60% of the time because they look great and it's easy to see how much time you've got left. On the other hand, digitals get about 40% of my wrist time, especially when I'm in a casual, sport, or technical mode.

Well, here's a watch that's the best of both worlds. With this Marine Gear, Casio has a real classic "diver" watch both in form and function.

In function, this watch has all the classical functions I like in in the digital line-up: stopwatch, alarm, hourly beep, and date. The digital time and dual time has come in handy, especially travelling. In fact, with the analog hands, you can have three time zones on your watch at once. Also, it is easy to synchronize the digital and analog seconds. In the analog department, the hand are the easy to see-at-a-glance oversized diver fashion. The hour markers are made to show up in the dark. My only disappointment is that the luminosity lasts only for an hour so in the dark; it won't get you through the night. But that's only a minor let-down.

As to form, here's a real classic look in the world of water sport and divers watches. I've found that the hefty steel case, elapsed-time ring, canary yellow dial, and wide black divers strap make a really attractive and tough-looking wrist accessory that get lots of remarks like, "great watch!" from friends.

I first noticed this Marine Gear in about 1989 and immediatly thought, "Wow, gotta get this watch!" (In those days, the first Marine Gears has the function pushers at 8 and four rather than at 8 and 10 on the latest models.) Even though that watch is still working fine after about 15 years, I got a couple of others too. In the mid-90's, Casio put out a models with black and white dials and steel band. I like them too, though I wear them with the the black divers bands which still seem readily available as replacements. However, after all, I think the Yellow dial model is still the coolest.

Take it from a watch freak who thinks the bigger the better, if you're into the divers style in watches, you'll come to like the size and heft of this Casio and its tough indesructability and maybe come to think too that is one of the greatest of all time.

5.0 out of 5 stars Men's Casio Divers Watch, October 11, 2005

By	Richard B. "415Coupe" (Georgia) - See all my reviews

This is my third purchase of this same watch in the past ten years. I am very hard on watches and beat the heck out of them. I keep forgetting to remove them when working on Airplanes and auto engines etc. I dropped one and the second hand fell off which jammed the works. The other two still work but look like heck. Bands are lousey and break in short order so get a new band to replace it and keep it handy. Price from Target was $20 cheaper than Wally world and that included shipping. Some complain of not getting a good seal when replacing the battery and that will allow moisture into the watch and fog up the crystal. If you are VERY carefull and use the tinniest bit of vasoline to hold the O-ring in place when reinstalling the back it will seal just fine. Also, don't open it up on a wet and humid day.
