    This is my first compass watch. I was concerned that the compass would be difficult to use and calibrate. After receiving the watch I was easily able to use and calibrate the compass. A neat undocumeted feature of the watch is that the current time is displayed in all modes - world time (which also shows the name of the world time city selected), compass, stopwatch, countdown timer, and alarm. The digits are large and easy to read. The backlight illuminates the digits, not the whole watch face. The cloth band is very comfortable and looks sturdy and well made. All in all a very good value for the money.

    I bought this watch recently and as any Casio watch its great looking and worth fully for the price tag. Compass, World timer, Stop watch, Alarm and timer features are great and easy to operate. My only complain is the thermometer which I find practically useless. The instruction manual says watch sensor needs 30 min to adjust to the atmospheric temperature. For instance if you take your watch from warm place to a cold environment it will give erroneous readings for 30 mins!! And if you are wearing your watch, you can't depend on the reading at all since body temperarture will ridiculously increase the reading even in a cold winter day! If you take off your watch and try to measure.. you have to wait 30 mins to get accurate readings. So this sensor is not useful at all for measuring temperature when you are outdoors. Other than this, I like the watch.

    Some great reviews out there but I thought I would do a thorough review of the pro/con's.

    *** Pro: ***
    Large face
    Nylon band (last longer)
    World time
    Dual Time
    Stop watch/Timer
    Compass (w/ declination)
    Temperature (w/ calibration)
    Back Lit
    Protected Face (recessed)

    *** Con: ***
    Alarm too quiet
    Compass time too short
    Back Light time too short
    Temperature reads body temp

    First off I got this watch for world traveling. Reading the reviews I did not see anyone mention that it has the capability of doing Dual Time. Basically you can have your "Home" time zone on top and "Current Location" on bottom. This is great and was exactly what I was looking for. Once you set-up your home time then you can flip through world cities while traveling. It also has Day Light Savings mode for the Dual Time in case certain cities that you travel to do not have day light savings.

    Some people claim that the compass is inaccurate. Well first off I calibrated it, then I set my declination. Many people failed to mention this in their review. There is a feature where you can adjust for your location. My home city's current declination is 16deg. That is huge, so you have to adjust it for this. I am sure many people did not even realize this feature. Finally I measured my casio compass with a real compass. I would say it is about 1-3 degree's off of my real compass.

    I have been trying to calibrate my Temperature gauge. I have a home digital temp and my casio reads about 0.4 degree higher than my wall temp gauge. Of course I am not even sure if my wall temp is that accurate. To me 1/2 a degree is not bad for a watch. Mind you that this is calibrated with air temp, not on my wrist.

    One of the major problems purchasing this watch were the large number of reviews that were negative - because the purchasers aren't knowledgeable in technology or skilled in land navigation. Two complaints kept popping in in various posts, that the compass wasn't accurate and the temperature readings off.

    First, It has to be acknowledged that you are strapping a compass and thermometer to your arm where it will have direct contact with your skin, and using it in areas that affect it's performance. The most basic source of error is the fact that magnetic north isn't at the north pole - it can and is up to 15 degrees or more in error by its physical location hundreds of miles away. And that we are trying to measure a natural line of magnetism at a very low level in built up human habitation. We use a lot of electricity, it creates fields, and it's part of our construction which can be largely steel.

    Bluntly, being ignorant of that is the source of most of the complaints. The watch works fine, in fact, it's a great watch with features lifted directly from models priced $100 more and up. The compass works IF you bother to set the declination and then use it within its mechanical limits - such as keeping it level to the earths surface when activated. No compass using earths magnetic lines can find north if it's tilted up to any significant degree - but that is how we typically look at a watch. And no thermometer will read air temperature strapped in direct contact with our body - it will read skin temperature.

    What we have are customers who are buying an affordable Pro Trek grade watch who don't have the training and education to understand it.

    I looked around a lot for a watch like this, and read a lot of reviews before buying it. I wanted a good, dependable EDC (every day) watch that could time me on runs, hikes, and help me out on the trail with some general direction, all for less than $75. I actually ordered the comparable TIMEX (Expedition Trail T49612) version of this watch and sent it back. The TIMEX was huge, hard to read, and just didn't look good (greenish markings on huge black rubber case). I seem to keep coming back to CASIO because they seem to just "get it right" for me.

    What's the difference between the SGW100B-3V (this watch) and the SGW100-1V, you ask? It's the same watch, as near as I can tell, except the 3V has a high-quality nylon wristband and the 1V has a rubberized sports band. I chose the 3V because I have not had good experience with rubberized wristbands. They aren't too comfortable, either. I wore a G-SHOCK for a few years until all the eyelets in the band tore into one, long slit. This didn't hold my watch on too well, and I lost it in the ocean. The nylon on the 3V is great. It is durable, looks better than the rubber wristband, and is comfortable. It doesn't pull on my arm hairs like the rubber always did.

    Now, for the watch itself. Great readability and functionality. I like the how the seconds are displayed on the line under the hour and minutes, so your eyes instantly fall on the 4-digit time. The ILLUMINATOR feature makes all the digits shine, but not the face. This makes the watch extremely readable in the dark, but you're not going to be able to use it like a mini-flashlight. The 4-button controls are easy to master.
