SGW100 Series | Digital Watch & Compass | 200M WR | 100 SEC Stopwatch | Twin Sensor for Direction & Temperature | Low Temp Resistant | World Time | Auto Calendar | Multi Alarm

I'm extremely impressed with the Casio SGW100. The watch colorway is attractive (black band, black casing, orange and navy highlights) and looks rugged and cool. This watch comes with lots of features, and if you're just a regular guy like me, you'll find that it does the job. I did read some comments about the face being a little difficult to read as it has a dark background, and I can see the problem some may have- although I don't find it to be a issue for me personally, I actually kinda dig it. The watch illuminates for about three seconds and that can help sometimes. The band is comfortable, but I seem to be in between two settings, one is just slightly large, the other is just a little too snug. This allows the watch to slide ever so slightly when I am active, but that's a wearer issue, not manufacturing. The compass and thermometer are neat functions. The thermometer does read your skin temp vs air and you would need to take the watch off for a few minutes to get what appears to be a fairly accurate temperature reading. I'm no advanced boy scout, but the compass also appears accurate after calibration. Plenty of alarm functions (if you really NEED one, most use their phone), stop watch, timer and World Time function. I have a friend that lives in Italy, and I leave the World Time function on "Rome"- one button push shows me the time where she lives. The watch is waterproof 200 meters, or 20BAR, whatever that nonsense means. I'm not a diver, but I do swim a fair amount, and "20BAR" is plenty waterproof. I definitely recommend for the "Average Joe" who would like a nice, attractive, sporty watch made by a quality company for a very reasonable price. At the $55-ish price point, this watch is well worth the purchase!

Upgraded myself this watch after using a Casio F91W for a few years now, and I could never be more glad I made this purchase. Considering the features that are on this watch like the compass and thermometer, it's still as light as my first watch. Knowing that the battery will last me 3+ years gives me some time to breathe. Speaking of breathability, it's also tight on the wrist, enough for it to not move around much but is recommended to take it off after a short day of use. The blue & orange patterned designs of the watch helps it stand out and gives it a good distinction of what button functions are for. Compass is shockingly accurate when set up correctly (also carefully) and the thermometer is slightly off but does read a good average temperature wherever you're at. World time zones are also pretty neat to have whenever you want to know what time it is from the other side of the world. Overall, with its minor flaws and major ups, this is a great watch to either start out, upgrade, get for someone you care about, or just to collect. Highly recommend it to anyone looking to detox from smart tech watches and go out on adventures offline. 4.5/5

After having numerous smart watches, it is a welcome relief to have a watch that you don't have to pair with a phone, recharge a battery every few days and one that doesn't bug you with a bunch of notifications. Casio is a legendary brand in the watch world and this one does not disappoint. It has the best looking face that I have ever seen in a watch (and I have had some very expensive ones over the years). The detail around the rim is exquisite- the compass rose, the coloring - perfect blend of purple, black and orange highlights... even down to the font on the crisply printed letters. The LCD portion of the watch is actually not that big but is still plenty large enough to read (I have progressive glasses and still have difficulty reading the smaller print in most watches - not this one!). I was initially skeptical of the negative (inverted) LCD face. It looks really cool but I find most are dim and difficult to read. This one is very crisp and clear, even in lower light levels. The band fits the watch's design and form perfectly and is comfortable to wear. I type a lot at work yet this band does not bother my wrist at all. It does tend to grab some hair on my wrist when I initially try to put it on (minor annoyance) but once its locked in place it is fine. Features: The compass is the most interesting part of the watch for me. It works really well but is not always active. You have to press a button to activate it (this is to conserve battery). After some calibration, it has matched up perfectly with my old Brunton compass. Impressive feature is that you can even set the magnetic declination. The second part to the "dual sensor" is the thermometer. It works as it should and is pretty accurate, with one caveat. To get a true air temperature reading you need to take the watch off and let it sit somewhere for 20-30 minutes prior to reading the temperature. This is to eliminate your body heat. If you were to read the temperature while wearing it, it will read several degrees higher - this is to be expected and is the reason you don't normally see this feature in a watch. The temperature reading is activated at the same time as the compass, so it is not always on. For me, this is most useful at night while camping. The rest of the "normal" watch functions are exactly as you would expect. World time, alarm, stop watch, etc. Nothing special here except for the fact that all of the settings are very intuative and easy to use. The backlight gives off plenty of light to see in total darkness, however it only stays on 2 seconds with each button press. I would have preferred at least 3, but this is very minor. All in all this is my new favorite watch. It is very comfortable to wear and looks amazing. I love hiking and enjoying the outdoors and I feel like this is the perfect watch for an adverturer such as me. I will say it is a bit thicker than many watches (almost as thick as most G-Shock watches, but not quite). The design of the bevel and rim is curved, however, so it does not snag on my clothing or anything. At $55 (price at time of purchase) I consider this an amazing value. If you are thinking about this watch, don't wait any longer. Go ahead and get it. You will not be disappointed.

I got this watch a few weeks ago because i needed to replace my S&W Military style watch. The band snapped off, cheap bands great watch. But enough of that, im here to describe my experience thus far with the Casio SGW100-1V. It has a very comfortable wrist band (some sort of plastic material..definitely not cheap or akward feeling). The display is very clear and easy to read with large numbers for the time, day of the week abreviations, month and date. It does not display the year off hand, but i believe you can push one of the buttons to show it (im still learning this thing). And lets be honest, if you need to remind your self what year it is every time you look at your watch...well, i think finding a good watch is the least of your problems. Now as far as the features go, it does what most digital watches now a days do, it has the chrono stop watch, a timer, world time, 4 or 5 seperate alarms i forget (PS: dont buy this thinking the alarm will wake you up...unless you're a supremely light sleeper, you'll never notice its going off). And on to the reason i bought the watch....Yes, it has a built in thermometer and a digital compass. Now first off, lets be real...these two features are NOT 100% accurate, they are merely a means to get a "rough" idea of which direction you're heading or what the temperature is. The accuracy rating on the compass has a +/- 3 degree room of error. Now 3 degrees in the grander scheme of things could end up being a devastating miscalculation, and the thermometer is roughly the same. What i will say is the thermometer will not read correctly while it is on your wrist...your body heat DOES affect the reading. They say to take the watch off and let it sit on its own for a good 10-15 minutes before checking the reading. Now again, this is going to give you a rough idea...its not meant to be a spot on, right this second reading. If you are buying this watch for 100% accuracy on direction and temperature...dont bother. Buy a compass, and buy a legit thermometer. I bought this because i enjoy hiking and primitive survival out in the wilderness. So if my lensatic compass craps the bed, he guess what, my watch can help me out. And if im curious of the temperature, ill most likely have the time if im hiking to take it off, strap it to my pack while i walk and then check it again after a few minutes. If after having said that, you're still interested in the watch, i highly recommend it to you. Its rugged, ive gotten it wet (rain) and it hasnt fogged up, its comfy and most importantly, for all that it offers, you are getting it at a very modest price. I gave this watch a 4 star rating. Simply because its not a high end watch, and i would imagine there are certainly far better watches out there, but for what you get for the price, i feel 4 stars is a good rating.I hope this review gave you something to go on!

I own a few Casios and by far this may be my current favorite. It sports a good sized face (46.6mm NOT 51mm) and mineral glass. Water resistant to 20 Bar/660 feet. So shower proof, pool proof, surfing proof, and is Low and High temperature resistant! Built for the temperature range of -10 Celsius to 60 Celsius/14 degrees Fahrenheit to 140 degrees Fahrenheit. Once you own a Casio adjusting the settings becomes almost intuitive, for most other Casios. I found this one is particularly easy to navigate and set, even the compass calibration was a cinch. If you need additional visual assistance there are YouTube videos for this. Other users advise to manually re-calibrate it once a month for best accuracy. I didn’t have to calibrate the temperature - it was automatically correct. Yes remove it from your body for a few minutes then take the temperature for most accurate reading. The black out screen is a personal preference. In the daylight or in well lit rooms there is no problem reading the screen. In darker environments you need to hit the light for an assist often. This has the Casio basics: 5 independent alarms, 4 one time alarms and 1 snooze alarm, world time, stopwatch, daylight saving on/off, timer, 12/24 hr format, calendar displaying month/date/year and a MUTE option too. So no beeps! Another plus I haven’t seen on the other Casios is that the current time remains as a constant in the upper left hand where the date is on main screen. This way you know what the current time it regardless of what mode you are looking at including the world time mode. I found it to be pretty helpful so you don’t have to exit the stopwatch, timer, alarm or need to click out of world time to compare time difference. Only con I can think of is that the strap is different and I’ve read other people encounter issues attempting to switch it. Personally the band is good and fits well so I won’t worry about swapping the strap anytime soon. It uses a 3 yr CR2025 battery. The back light is set to about 2 seconds. If you use the backlight often know you will probably need to change the batter sooner than later but that’s not terrible either. Update 12/21/2025 As much as I loved the dark look I became frustrated with the need to constantly use the light in order to see anything on the face. I ended up returning it, in completely pristine condition for its next owner. I ordered the SGW-100-1V and it’s been such a visual improvement. I love the watch more now that I can simply just glance and know the time. I noticed on most new Casios if you look at the screen straight on it isn’t ideal, instead it’s clear if viewed on an angle. This watch is clear straight on and funky on an angle. Just an observation. This face is much easier to read especially if you dive or are in water.

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. Here's a pro-tip for you: Rather than straining your eyes to read the tiny operation manual, look up the PDF online from Casio and use the zoom to read it like normal text. The digital thermometer is just as others have described. On my wrist, it usually shows about 85 degrees (no matter what the air temp is), but it is accurate when the watch is unworn for 30 minutes or more. The temperature is factory calibrated, but you can check it against another thermometer and adjust it by a few tenths of a degree if you wish. I think the thermometer function is helpful for waking up in a tent or bivouac with your 3V next to you and checking the temp before you crawl out of your bag. The digital compass is excellent. I have checked it against several other commercial and mil-spec compasses and it's readings are pretty dead on. Even though CASIO says it's not meant for accurate land navigation, but more for general direction, I feel it could hang in there for some basic land nav. There are 16 directional arrow indicators around the outside of the face for indicating North, so your arrow is less accurate than your digital compass degree reading (360 degrees). The compass needs to be user-calibrated something like every 100 days. This means spinning your watch 360 degrees while it is taking readings. I'm really not sure what the purpose of this is--it might have something to do with ensuring the magnetic sensor has not become inaccurate due to ambient magnetism or a bad bearing. There is also a declination adjustment (look yours up online by ZIP code) so that your watch can show you true North. I play a little "game" with the compass when I'm bored. If I'm somewhere I've never been, I'll mentally guess which direction is North and check myself with the watch. I know; I'm a nerd. The world time feature is great with plenty of city time-zones and a DST toggle. If your friend is overseas and you want to know if it's too early/late to call, it's literally ONE button-push away to check. I keep mine on LON (London) time so I can quickly see UTC. Standard stop watch. Elapsed, split time, and two-finisher capabilities. The buttons are pretty easy to push, and this helps with reliable start and stop. We've all been there, with our thumbnail on a tiny metallic button, when we tell our friend, "Ready... Set... Go! Wait, I mean, Go! Now!" Standard timer. Keeps going when viewing other modes. Four alarms WITH snooze function. Not bad! Overall, the watch just looks good. I would say it gives off a hiker or possibly military-type look. The different colored markings on the case and the silver/grey bezel kind of catch the eye. You can tell it's not a cheap drug-store watch just by the look of it (which is more than you can say for some of the CASIO styles). If you're not used to a large watch, you'll think this is pretty big. It's fine for me. I do have to lift it slightly up on my arm when getting into the front-leaning rest position (push-ups) or else it digs into the top of my hand, so that's something to consider. I have three minor nit-picks of the watch, but not enough to dock a star-rating on a stellar watch: - You can only scan through the time-zones in WT mode in one direction. - I can't remember which mode this was, but at one point I was adjusting a value on the watch and the positive (+) button was lower right and the negative (-) direction was upper right. This seemed backwards to me. - The wristband is attached the case by a pin which is held in place by a small steel buckle that is hinged to the case. Most other CASIO cases have a giant protrusion that encloses the strap and pin. It makes me wonder if the connection is a little weaker than on other CASIO watches; but time will tell. Overall, this is a great watch. The 200M rating is reassuring for any aquatic activities. The strap is comfortable and the watch itself is surprisingly light. I bought this watch thinking I would only put it on when wearing jeans, work clothes, or clothes for hiking, but I've ended up wearing it every day since I bought it. I would not wear it with coat and tie, however--that's kind of where I draw the line.

Pretty neat features. Love the compass and the thermometer. The fact you can recalibrate the barometric and declination settings is pretty slick. The hinges are reinforced too. Prolly the nicest watch I’ve ever owned. And it’s only $50.

Watch is good, compass and stopwatch other features as advertised. The thermometer does not work. The temp is consistantly 15-20 degrees F higher than actual conditions.
