Summary: This is a nice watch and I wear it almost every day. The problem I have with it is that it doesn't meet the purpose that I bought it for. I wanted a watch that showed the outdoor temperature after having a heat stroke and being instructed not to stay outside in temperatures over 90 degrees F. Unfortunately, since it is strapped to your arm, your body temperature impacts the reading on the watch and it is never correct while being worn.
Not as big and doofy as I feared. Compass works well.

Summary: <<--EDIT-->> January 03, 2014 I've had the watch for about a year, wearing it every day, and until now it had been working great. A week or so ago though, the light stopped working. Then the watch itself just went black. I bought a new battery and installed it, but it the watch no longer works correctly: There is no more audio and you can't change settings. It worked great when it worked, but I didn't even get a full year out of it and it's toasted.
Summary: I always buy a watch similar to this, sometimes with a compass sometimes without. Every two or three years I pity the poor watch that has been on my wrist for so long and get a new one. At any rate the compass on this watch will tell you about which half-quadrant you are facing. Not much better than that. Still that is about as good as it gets for the price. I would never use it as a replacement for a real compass to be used on the water.
Summary: I love Casio watches. I read the reviews on this watch before I bought it and was aware that the temperature and compass may not work as expected and that was the case. I have zero confidence in the compass reading and the temperature. If they worked good I know that I would have used them frequently. Beyond that the watch had all of the features that I was looking for. It fits fine and is comfortable. I like how it looks.
Watch arrived with light scratches on the case back.

Summary: The Casio watch sgw100b-3v arrived with light scratches on the case back. The watch is made in China. The tiny font in the small manual is best read with a magnifying glass. The loop to tuck the strap is glued, not sewn.
Summary: The watch is well made. Nylon band is very sturdy. But the alarm sound is too weak to hear. There is no way you can hear it when you are sleeping. I don't think it can be used as alarm to wake someone. So the alarm is useless.
