Casio SGW-100, the outdoors companion and a a tough beater

Got it for 340 reais, or approx. 68 dollars. A bit more than how some of you might get for retail, but this model series is rare to find here in Brazil, only a handful of sellers have it and all are imports, so prices are higher. Got it second hand, from a seller who had a Pro Trek and passed on this one for cheap.

Although not a Gshock, it feels tough. The resin case is solid, pairing up with the mineral glass, meant to be resistant to impacts. My particular model has a slight crack, due to previous use, but it is microscopic at best, and not at all being a threat.

The dial is an LCD display, and particularly readable, since the main dial is huge and easy to read, but the smaller numbers/date info are not that hard to check either. The night light is a 1.5 second greenish blue light, making the dial not too bright but effortless to read at darker lights. I wish it had an adjustable light time like my AE1200.

It contains some of the common features probably found around other feature-packed watches from Casio: Dual time, stopwatch, timer and alarm. And, of course, it tells the time, as it should in the first place. Some features are different from my AE1200, like it has a snooze mode for alarms, and the timer has a cycle mode, as in the timer repeats until you stop the count, but you can't set seconds on the timer, which is a shame.

However this watch has a distinct feature: a Twin Sensor, that is, a in-built thermometer and compass! Calibrating them was a bit weird, since the booklet is cryptic at best, but they do work. 

And the compass even had a feature I never thought about: declination level adjustment. The best way I can explain, being an amateur in physics: Since Earth is slightly tilted, and the magnetic poles are not exactly on the geographical poles, there are places on our planet your compass will deviate from the true north by some degrees, which is why you need to count how the declination level is varying. (If I said something wrong, please let me know! I was just baffled about this fact and how it was related to my SGW's calibration).

While calibrating this watch's compass, you can adjust how many degrees to West or East to adjust, and also correct the thermometer's current displayed temperature. The temperature range it shows is from -10° to 60° Celsius, so more for an outdoors range.

Personally I don't need these features that much, yet it doesn't keep me from wanting them for how smart it is. And if I ever went into an emergency, having a compass and thermometer on the go if I am in somewhere far away from civilization, for example, can be helpful to manage direction and my knowledge on the environment. If I had to keep only one watch, this would be it.

Other feature I liked of it was the NATO strap it came on, it is so comfortable to use I sometimes forget I have this watch on my wrist.

This is a great beater watch. I would use this for outdoors or for future trips. Could be perfect as an everyday watch as well. If I have to leave home for long periods of time, I would surely choose this watch to go with me, because if I ever run into an emergency, I wanna be using this watch. If not for features, it is for the durability.
