Casio Men's AQ190W-1A Multi-Task Gear Sports Watch

It has a big, busy face, reminiscent of both aircraft controls and a retro communications device in an old science fiction movie. Its shiny, wide outer stainless steel ring is striking, as its the circular display marking off seconds as pie wedges. The 100-meter water resistance a very practical feature. It has a thin, comfortable rubber band whose durability I have yet to test. Its large digital displays have superior visibility. It looks bold, original, and distinctly Japanese in its quirkiness. But I didn't purchase this watch for any of these attributes. I bought it for its remarkable technology and how I could use it.The watch has a panoply of features characteristic of Casio--combined analog and digital format, full calendar, timer, world time information, and multiple alarms. Besides these, it possesses two much more unusual features that put it near the forefront of timekeeping innovation. The first of these is a velocity indicator. To use it, you enter in advance the number of units of distance to be traveled (the choice of unit does not matter), record the beginning and end of your journey by pushing an elongated button on the side of the watch, and the indicator will display velocity in units per hour. The number of distance units selected can range from 0.1 to 99.9. This indicator is a vastly more general and useful tool than the traditional watch tachymeter, which can only measure velocity over a single unit of distance (for example, one mile or one kilometer).To me, the most interesting feature of this watch, and the reason I bought it, is its remarkable chronograph (another term for a stop watch). While chronographs are very common in the watch world, the one-thousandth of a second accuracy of the present model is most unusual. Even other Casio models typically measure to only one-hundredth of a second (a "jiffy").Your reaction to the one-thousandth second chronograph may be that it reaches a totally unnecessary level of precision. I have long had an interest, however, in knowing the minimum time interval that a human being can observe. I have therefore used the chronometer on this watch to conduct an informal experiment on this topic.My experimental procedure was the following: I used the chronograph to attempt to measure a preselected interval of time. I pressed the start button to begin recording the interval and the stop button (actually the same button) to end the measurement. I then recorded how close to my goal my actual measurement had come. I selected time intervals that fell precisely between the one second measurements on the chronometer, that is, 3.5 seconds, 4.5 seconds, etc. My most frequent goal was to reach 3.5 seconds. My selection of these particular time derived from my effort to eliminate, as nearly as possible, visual cues on the watch face. Although the digital readings of individual seconds on the watch face can be easily seen, the whirring one-tenth second time changes are very difficult to observe, and the one-hundredth and one-thousandth changes impossible. My measurements were therefore those of my internal perception of time. (This was thus a very different experiment from those of psychologists who have attempted to measure the shortest visual signal that can be observed). Also, by selecting a time value falling exactly between two one-second markings, I was able to perform the mental calculation of "one-half a second." This was a mental calculation akin to that in music where the performer counts half beats.I quickly realized that my accuracy in time estimation depended on whether I was, in athletes' terms, "in the zone." At the level of precision I was trying to achieve, the slightest distraction or hesitancy would lead to quite inaccurate results, off by as much as tenths of a second. When, however, I was "in the zone," I could typically record a time within one-hundredth of a second of my measurement goal in three out of five consecutive attempts. In my best extended sequence, I came within one-hundredth of a second in seven of ten consecutive tries. I achieved these results despite the basic clumsiness of the apparatus, which consists of a button that can only record a measurement after traveling a considerable distance to the bottom of its range and which imposes resistance to my pushing finger. Based on my experimentation, I have reached near certainty that I am able to distinguish time intervals of not more than one-hundredth of a second.What has most surprised me is that I have compiled preliminary data showing that my time perception probably approaches the level of one-thousandth of a second. I base this conclusion on the high frequency at which my recorded time intervals have fallen within three or four-thousandths of a second of my goal, despite the imperfections of the watch as an experimental tool. On one occasion when I tried to reach 3.500 seconds, I recorded successive readings of 3.500, 3.499, and 3.499. On another occasion, I hit exactly 3.500 seconds in two out of ten tries. What is more, even when my successive readings were far off the mark, they commonly remained very close to one another, differing by as little as two-thousandths of a second or less. In other words, I was making repeated mistakes of nearly exactly the same magnitude.Although my research on this topic has been preliminary, I believe my results can serve as an inspiration for more rigorous experimentation using more sensitive equipment and the use of statistical techniques. The potential implication to our understanding of ourselves is vast. If our experience of a conscious "now" falls near one-thousandth of a second or an even smaller interval, think how multitudinous is even a second of our lives! And when we truly grasp our overwhelming multiplicity of experience, we will at last understand that we are inseparably connected to one another.

Hey, this was a great watch for the price. I bought it for my family trip to Hawaii, and it worked as advertised. I tested it in the pool first, and it did not leak. It has some nice features, such as the ability to keep time in multiple time zones, as noted in other reviews, and it is kind of spiffy to watch you change time zones (once you remember how to do it) and the hour and minute hands go twirling around from the old to new zones.I snuba'd down to about 30 meters, and it kept right on ticking. I wear it now when I wear short sleeves in the office. It's really not a bad looking watch.

First off,I received the watch quickly after ordering. I opened the package and set everything up in a short time. I recommend reading the manual so you can be better understand and appreciate the features and functions of this watch.I like the face of the watch and the option of making it an ANAdigital by merely pressing a button.The watch is very lightweight,the band is the normal mediocre type.You also must be careful because the crystal is easily scratched.I just noticed this now!I love the luminous hands on the watch.The hourly chime has a low tone.This is some of my most important observations to date.So overall I would recommend this watch.

This was my first Casio watch and let me tell you, I am thoroughly impressed.The first thing that struck me is that this watch already had the time set. The time was exact down to only being a matter of seconds off the actual time. That includes the date, year, EVERYTHING. I have NEVER had a watch come out of the package and be practically set already. All I really had to do was choose my proper city (in other words, the proper time zone) and it was set. The analog minute and hour hands are synchronized with the digital time and spun around automatically to display the proper time. VERY neat to watch. It's also amazingly thin for an ana-digi watch. Most watches of this type are ungodly thick and wide. I'd say this is fairly on par with a digital-only watch.This watch is loaded with features. Instead of simply having a second time zone you can set, you can set it for major cities all over the globe. A couple simple key presses will even switch the second time zone to the primary time zone. It even has Daylight Savings Time. The alarm system allows for multiple alarms, and even includes a snooze feature of all things. There is also a countdown timer (I call it the egg timer) and the watches major feature, the chronometer, or lap feature.The normal advanced features are available, lap/split time etc. However, that extra dial in the bottom of the face comes into play here. You can set your total distance you are running, riding, etc. After you've run your distance and you stop your time, start your next lap, or whatever the dial will actually approximate your average speed over the distance you indicated. This would be a great watch for track runners or bicycle enthusiasts. Simply amazing technology.So why did I give it four stars instead of five, you ask? Well, there's a couple of flaws in this diamond. Firstly, when they say the display is lit by LED, they aren't kidding. There's a single yellow LED on the right side that shines light across the face of the watch. I thought this technology died a well justified death with the introduction of electro-luminescent technology. Apparently I was wrong. While this adequately illuminates the analog portion of the watch, one must struggle mightily to see the digital time which is partially shadowed. Also, the light throws off a bright yellow band of light to the left of the watch. Great for an emergency "flashlight", but annoying or even startling for anyone sitting to one side of you. The other reason I had to knock a star off is the manual tells me that, even hardly using any features on the watch, I can expect a whopping two years of battery life. In the wake of watches being advertised as having 7-year or even 10-year batteries, I am woefully unimpressed. That alone is a reason to give it only three stars, but there are so many great things about it that I didn't have the heart.If those two negatives about the watch don't scare you off, then buy it! It really is a great watch packed with so many features. It's just a shame it had to come with an Achilles Heel.

This is my everyday, 24/7 watch and I love everything about it. Its functions, its size, its looks. Everything. Easy to use and easy to set.If there's one small complaint, when it's dark, don't bother with pressing the light button. Not going to see much. Light only comes from one side. But you really don't need the light because the hands glow in the dark, so you can see what time it is.

Excellent watch, it's very easy to use, the alarms are very useful.

E' il terzo per me. Leggero, preciso, completo di tutte le funzioni, praticissimo e display originale quanto chiaro. Il prezzo è ampiamente giustificato oltre le aspettative. Io credo che sia uno dei modelli Casio meglio riusciti. Lo consiglio a tutti coloro che vogliono contenere i costi senza prendere un orologio di basso profilo. L'unica pecca è il vetro in plastica. Peccato. Il resto è perfetto.

I got this for my husband as his one broke and tried to get a replacement he loves it to bits and was very pleased with it quick delivery

Great watch

Great finish a looks. Perfect service.
