The Casio Story

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 AMW340-1A seems like a newer version of the AMW320R-1EV, October 16, 2009

This review is from: Casio Men's AMW340-1A Analog Diver Resin Strap Watch (Watch)

First, the guy who rated this watch at only one star was talking about the larger AMW320R-1EV. This one, the AMW340-1A, is slightly smaller (see my photo) and has a third function button on the right side, just under the crown. My 320's crystal was getting scratched up so now I own both.

The 340 is slightly smaller, thinner and lighter than the 320 but just as nice looking. It has only one digital time display, not two, like the 320. But the digital stop watch function has "split times" and a way to record the time of two finishers (that I don't yet understand) which the 320 doesn't have.

Neither watch has a count-down timer, and neither has a backlight. Many complain about this but I don't seem to need either, though a backlight would be nice. I'm really happy with it.

4.0 out of 5 stars Great watch. Could use a light, June 15, 2009

By 

Product Kinda Guy (Someplace Sunny) - See all my reviews

This review is from: Casio Men's AMW340-1A Analog Diver Resin Strap Watch (Watch)

This is a smaller sized diving watch. It is not too small, though. It is actually nice sized, and reasonably lightweight. The LCD screen is actually larger than the one on Casio's classic large face dive watch (AMW 320). The improvements that would be great for this watch would be some kind of illumination of either the actual face (and sweep hands), or the LCD screen. The sweep hands are luminous, as good as any Casio luminous hands. Another improvement would be a better positioning of the AM/PM designation in the LCD screen, which is nearly impossible to read because it is postioned so high. To overcome this lack, when setting an alarm, you can toggle to 24 hour time to make sure your 6AM is AM indeed. Another feature I would personally have liked (which is the only reason I returned the watch) is a countdown timer. The LCD format does not have that one feature, which I happen to use frequently. Bottom line: Great watch if you're OK without a countdown timer and without illumination.

As another helpful post said, this Casio watch model is the AMW340-1A, not
the larger AMW320R-1E that was indicated by someone who gave it one star.

*Edited & Updated on Tuesday 10/12/2010*

I own five Citizen & Casio Chronograph sport watches packed with features, subdials, day/date, dual time, world time, alarms, count-down timer, etc. However, I wanted something sporty & fairly rugged that was less expensive (in the $50 range) that would fair well and still clean up nice after working hard around the house, the yard, the car and the garage...ie: something that would take a beating now & then without having to worry about getting any of my nicer watches all scratched up or possibly damaged. Yeah, a "scapegoat-watch" to take all the minor abuses and infractions I have frequently subjected my nicer watches to.~;o)=

Most everything else I looked at in the $50 range were just too cheap, plastic, or didn't have enough features (if it was all-analog), or just too geeky & gaudily digi-tech looking for my taste (if it included digital features). I wanted a suitable good-looking sporty analog/digital hybrid 'scapegoat-watch' with essential features (such as analog, chronograph, day AND date, dual time, alarm), but at a LOW PRICE and in an all stainless-steel case to endure some dirt, grime, and occasional punishment. (Timex was simply out of the question for me because I've never had a Timex take my abuses for more than a year or so before it broke.) I've been somewhat spoiled from having decent chronograph sport watches with useful analog/digital hybrid features. Thus it's been a tough long search over the years (poor me) finding a nice-looking sporty diver-style watch that's suitable (fairly-rugged in an all stainless-steel case) as well as useful (with a rotating bezel and most of the essential features that I like)...at a low *price.

*You can get this watch for $42.99 w/free shipping at Over Stock
dot com, which certainty helps clinch the deal as a bargain watch.

For the price, this Casio AMW340-1A sport watch fits the bill. I'm also happy to say, that this watch looks nicer in real life than it does in its photo debut here at Amazon. Here's an analog/digital hybrid watch that looks good (like a genuine diver's watch), comes in an all stainless-steel case with a fully functional rotating bezel, and has most of the essential features I look for...all for under $50 bucks. And I'm also pleasantly surprised that after 3 months of constant use and putting it through its paces, my Casio AMW340-1A is only off (fast) by 3-seconds, which is pretty accurate and a swell performer for a watch just under $50 bucks!

Let me just say...I did not get this watch because it dazzles (it doesn't). I did not get this watch because it's jam-packed with every useful hi-tech Swiss Army-like feature out there (it isn't). And I did not get this watch to impress my scuba-diving & rock-climbing buddies either (it doesn't even impress me). Simply put, I got this watch to let it get dirty, scratched, and all banged up while doing all my handiwork around the house, yard, car, and garage...so that I could spare my nicer watches after extorting 10 yrs of hard service & slavery from them. Honestly, I have yet to take off this watch after 3 months (except to clean it) because it has filled-in rather well for my other watches...better than I had expected from a "cheap" $50 dollar watch.

*Note: Please disregard the first photo above, this watch does NOT have an illuminated digital display window as apparently shown in the 1st photo above. The added customer photo is the ONLY pic above that displays the digital window realistically (see customer pic above).


CASIO AMW340-1A SUMMARY FEATURES & SPECS: A Sporty Diver-Style Analog/Digital Hybrid Watch

-The Casio AMW340-1A is a simple, battery operated, *medium-sized (41mm wide), sporty diver-styled quartz ANALOG watch in an all-stainless-steel case and a fully functional rotating bezel, with some additional (basic/essential) multi-mode DIGITAL quartz functions in a discrete digital-display window.

*Note: The Rolex SubMariner is only 40mm. This 41mm Casio is not a "small" watch. It's technically an "average-sized" or "medium-sized" Men's watch. Whereas the AMW320R-1E pictured along side this watch (in the customer photo) is "large".


CASIO AMW340-1A DIGITAL FEATURES & SPECS: Digital Functions

- Digital chronograph with dual split times (elapsed time, split time, and 2 finishes); the chronograph has a 1hr measuring capacity/limit in units of |MIN'|SEC"|1/100sec|, ie: [00'00"00], for a total of 59min & 59.99sec max, or approx. 1hr max/limit, ie: [59'59"99]

- Digital day & date calendar displaying "month|day|day-of-week", for example: [06 17TH] on the digital display is June 17 THursday, not June 17th

- Dual-time operation (digital time can be set independent of analog time; see "Stainless-Steel Bezel" features below to yield a 3rd time in analog)

- Daily 24hr digital alarm for reminders (it's not loud enough to awake a normal-to-heavy sleeper, and maybe not even a light sleeper, but it is certainly suitable for reminders & appointments); the alarm goes off for 20 seconds unless the sound is manually canceled by pressing the start-stop/on-off button on the lower-right

- A 12hr and 24hr mode setting (affects digital time, dual time, and alarm)

- An hourly chime/beep setting (it's not loud either, making it quite useful rather than annoying); chime duration is approx. 1/2 of a second

- 3 mode buttons: Mode, Set, and Start-Stop/On-Off (these 3 buttons are in addition to the Crown which alone sets the analog time independently).


CASIO AMW340-1A ANALOG FEATURES & SPECS: Analog Features & Other Features Worth Noting

- Accuracy Rating: The Casio AMW340-1A is reasonably dependable and tells time accurately (it was offf only by 3 seconds after 3 months on mine, however, in the manual it's accuracy is rated at +/-30sec per month at normal temperatures, which is reasonable for a $50 watch.

- Impact Rating: This watch is fairly rugged and made reasonably durable because of its full metal stainless-steel casing (no resin materials/coating or ion plating anywhere on the body/case & bezel). It's actual Impact Rating is for: "normal daily use and light activity such as playing catch, tennis, etc." (which includes soccer, baseball, flag-fooball, jogging/running, light rock-climbing, boating, rowing, mowing lawn, etc). That is, it's not G-Shock rated for extreme vibrations such as industrial use with a jack hammer or chain saw, nor is it rated for extreme impact sports such as tackle football, motocross, extreme mtn-bike racing such as downhill racing and racing through extreme terrian with technical obstacles, etc.

- Water Resistance: This watch is rated "Water Resistant" to 10 BAR, or a depth of 100 meters or 330 ft (10 BAR = 10 ATMospheres of BARometric pressure), that is, as long as you maintain the watch and keep it clean and lubricate/replace its O-ring/seals when necessary. (See *Watch Cleaning Tips* & *Watch Battery & O-Ring Maintenance Tips* at the end of this review below.)

- Full Metal Jacket: It's sporty and handsome (it actually grows on ya) and is encased in an all stainless-steel full metal jacket (with a resin band as pictured), as well as a stainless-steel screw-on cover on the back for a better seal.

- Stainless-Steel Bezel: This watch has a 2-way rotating stainless-steel bezel with easy-to-see dual scales:
*(1) a 60min scale which can yield a 3rd time, and *(2) a smaller-font 360degree compass scale;

*(1) How to use the 60min scale on the rotating bezel to yield a 3rd time: Rotating the 60min bezel scale in-effect 'offsets' the inner analog 12:00 o'clock position to yield a 3rd time, OR it can be used to mark an upcoming-time, OR to mark the current analog time as an approximate start-time, OR to mark ahead of the current analog time as an approximate count-down time.

*(2) How to use the 360degree compass scale: Likewise, turning the bezel rotates the 360degree compass scale (it rotates the "N" North arrow). As a general rule: if you're in the Northern Hemisphere, simply align yourself so that the analog hour-hand on your watch points towards the direction of the sun; the position between the hour-hand and the 12:00 o'clock position on your watch is South. Then rotate the "N" North arrow on the bezel-scale so it aligns opposite to South...and poof!...you have a compass. [This info is not in the Casio manual, but it's in Citizen manuals for Citizen watches with 360degree compass scales.]

*Note: The Casio bezel on this watch does not appear to be very high-grade/or industrial-strength stainless-steel, however this could be because the brushed stainless-steel finish on the bezel-ring is not polished to as high a luster as the rest of the watch case[?]. Either way, when buying a sports watch, I never buy a sports/diver watch without a fully functional rotating bezel. For me, a bezel must rotate with clicks and have a 60min scale and/or a 360degree compass scale, OR it must have a full tachymeter and/or a rotating slide-rule scale (without clicks). In comparison, stationary bezels with limited markings are rather useless, or just decorative.

- The watch features a classic dive-watch design with large luminous hour & minute hands, a crisp (and luminous) second hand sweep, large luminous 5-min increments clearly marked on the face, plus small 1-minute increments as well as smaller (fine) 1/5th-sec increments. The analog portion of the watch face (along with the 60min and 360compass scales on the bezel)... Read more ›
