Casio Men's Twin Sensor Multi-Function Digital Sport Watch

The model numbers are confusing. Amazon's product page and Casio's website both call this SGW300H-1AV. Once you put it in your shopping cart on Amazon, it is referred to as SGW300H-1AVCF. I did receive the desired product with desired band (resin), and the packaging confirms that it is SGW-300H-1AVCF.I had been considering spending $150 for a barometer watch, and am so glad I discovered this instead. For about 2-3x the price of a bottom-of-the-line wristwatch, you get a barometer. But note that unless you live in a complete flatland, you will see pressure changes as you travel up/down even over very small hills. So, you learn to ignore the pressure changes as you commute, for example. However, this watch adds value in a few ways. First, you get actual local pressure -- not that of a city 30 miles away. Second, having it on your wrist gives you something to think about in idle moments (it's fun to watch the pressure change, watch the direction clouds are moving overhead, and imagine where the highs and lows might be). Third, it's kind of cool to see how much pressure changes with altitude. Actually, there's a down-side to this. Where I live, the pressure has been around 24.8 inches. Since all the weather reports and books use sea-level pressure, I have no intuitive feeling for whether 24.8 inches is high or low. I guess I will develop that with time, but for now I'm just watching how the numbers change over time. Actually, there is a pressure trend section of the watch which shows an arrow near the middle for small changes, and farther to the left or right for larger changes. It does seem to work in general, but I am not sure how reliable this feature is, since it sometimes seems to show a change that doesn't match my interpretation based on the numbers displayed. But perhaps it is referencing the original data at higher resolution, while I am displaying the numbers in mmHg, which is rounded to the nearest 0.05.The altimeter reading is merely calculated from the barometer reading, and I will probably place more trust in the GPS-based altitude on my Android device, since that doesn't require accounting for weather changes. However, it is convenient to be able to glance down at my wrist for approximate altitude while driving.The thermometer, which shows a compromise between your wrist temperature and air temperature, has but one practical use: To measure the temperature in places where you habitually take the watch off for long periods (e.g. bedroom or perhaps office). Even when you take it off, it takes a long, long time to adjust to ambient temperature. I made the mistake of recalibrating the thermometer, because I couldn't believe it was showing 80 degrees in my house half an hour after I took it off! There is no way to go back to factory calibration (although you can obviously re-calibrate using another thermometer). My advice is to be patient, and trust the factory calibration.The other aspects of the watch are just what you would imagine if you were to pay $15 for a non-barometer Casio watch. The displays are perfectly visible from all typical angles. The screen does not scratch from normal wiping with finger/shirt but I'm sure it will when it hits a rock. The watch is about 1-7/8 inches across (perpendicular to the band), not insanely bulky.The main design criticism I have is that, when you are in barometer mode, if you want to see the altitude, you have to press the Mode button five times to get into Time mode and then press the Alti button. Since other than the barometer/altimeter it's just a cheap watch, it seems silly not to allow the user to conveniently toggle between barometer and altimeter mode (e.g., just let the user press Alti while in barometer mode -- currently, this has no effect!). Also it would be nice to have the date displayed all the time without having to go into Time mode. Also, I would have gladly paid a little more if they could have added moon phase, tides, and sunrise/sunset times! Surprisingly, there seem to be no affordable watches that combine all these features. Since the pressure-trend display is blank in most of the watch's modes (or useless in Time mode, where it just shows graphic display of seconds), it would have been easy to put moon phase or tide height there, for example.I was going to buy the version with analog hands added (SGW400H), but was concerned the hands might block the barometer reading, which was the main feature of interest for me, so that didn't seem worth the risk. I would have bought that if it had a feature to automatically fold the hands down (which some expensive models offer). Another feature I thought would be cool is a graph-like display of the pressure over time, which some watches offer, but if you are commuting up/down hills that would not be meaningful most of the time anyway.All in all, it's a decent watch and well worth adding just $20-30 to have the barometer.

PROS: Rugged, retro styling, current time shown in every mode, accurate barometer, great feature set for the priceCONS: Digital display has modest viewing angles, resin band is thin, altimeter is pressure-basedOverall, this SGW300 series represents a terrific bang for the buck. I was debating between this watch and the G-Shock Riseman (which I may still end up getting one day). At 1/3 the price, this SGW300 possesses an accurate barometer with trend arrow, a world clock (more cities than the Riseman!), and good toughness (100M water resistance, works in both temperature extremes). Since purchasing the SGW300, I haven't been disappointed.Three styles are available for the SGW300: black resin band, green cloth band, and stainless steel (folded link) bracelet. I chose the black resin for aesthetics and functionality. The black looked stylish and uniform on the case (the green one has light gray buttons and a dark gray sensor on the left, which I didn't like) and the green window on top reminded me of some old-school Casio's. Plus I didn't want to deal with odor/sweat issues with the cloth band. On the negative side, the resin band does get thin and the buckle is plastic. The SGW300 does have 18mm lugs, however, suggesting that the band can be replaced should the original wear out. The buttons on the side of the case are easy and pleasant to press.It's a sizeable watch, but on my 6.5" wrist, the SGW300 looks and wears fine. [EDIT 11/2011- I ended up trimming 0.25" off the end of the band because it protruded a bit too much. I smoothed it down with an emery board. The overall look is much improved.)I love how time is displayed on EVERY mode. And the alarm tones are reasonably loud. The display, on the other hand, is merely decent. At some angles, the uncluttered display shows thick, dark digits quite clearly. Yet many other angles cause the LCD digits to fade quickly -- I've seen better (the Casio Fishing Watch comes to mind). Illumination of the display is produced by two amber LEDs, which work well. One can customize the duration of the illumination, a feature that more expensive models often lack.Like other Casio's, this altimeter is pressure based and can be unreliable if the weather changes. There is no trend guide for the altimeter, nor is there any memory mode. The thermometer, as mentioned in other reviews, needs to be off the wrist for at least 15+ minutes before correctly registering ambient temperature.The SGW300 is a hidden gem in the Casio world. It shares and sometimes surpasses the features of more expensive models. It lacks the frills of atomic clock synchronization and solar battery power (the SGW300 battery is rated to last at least 3 yrs). In the process, the SGW300 emerges as an affordable watch for its extensive feature set, handsome retro looks, and good durability. Highly recommended.

It's a bit big for my taste, lots of words and grooves on the edges makes it a bit annoying to wear. But otherwise a good watch with handy features. Note that the temperature feature is basically useless for every day use since it only works if you leave it for 30 minutes not on your hand.

Let me begin by saying I have had many, many Casio watches. G's; Rangeman; Mudmaster; Protrek; the squares and rounds, thick and thin.This one is simply the standout. Why you ask?1. Cost. Of course, you can buy a cheap watch that doesn't last, but Casio is pretty good that no matter what the price range you have quality .Whey spend more for a G or fancy features when the pricepoint here is super ?2. Visibility. In my late fifties, some of the smaller Casio's simply don't cut the mustard. This has a nice, large, easy read time function, with a smaller day/date at the top. Do you ever notice even on LARGER Casio watches that the screens are SO busy and full of dials the time itself is like watching ants crawl. Nice display!3. BAND. Often overlooked, I have had many watches from Casio that are nice watches, but the band was too stiff, or awkward , or didn't sit on the wrist well. This band is flexible, soft, and gets nicer over time. It is also easily replaced.4. I won't comment on altimeter and barometer, not my thing and many others can comment on that, but they work.In short, a nice, easy to read display, a great price, and comfortable band.Way to go , Casio!

Price: Amazing watch for the price (just under £50 when bought)Features: Has a built in Thermometer, Barometer, Altimeter, Alarm, Stopwatch, Countdown, World clock, Light, Waterproof etc.Quality Build quality is great with durable plastic strap and tough watchface glass and case. Looks great aswellFunctions:( Thermometer, Barometer & Altimeter) Much more accurate when off your wrist and placed on a flat surface.

After a watch stopped working recently this was the ideal replacement.

haciendo la comparación de lecturas de medición para presión y temperatura, es bastante confiable la indicación. la comparación la realice con un instrumento de laboratorio marca EXTECH.lo que no me gusto, fue la luz (LIGHT) que emite.por lo demas no tengo quejas hasta el momento.
