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!

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.

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.

This watch is by far the best watch I've ever had by far because it has a nice large crystal clear display and it's easily the easiest to operate plus it has some very useful features from the time it self to the thermometer and compass, only issue I have is only minor because it's just having to calibrate the compass every so often but it's not too much of a inconvenience as you have to press the set button and then turn the watch around ensuring that the arrow is always pointing up, but still a tad frustrating to be fair, but to be honest with you i would use that feature if I was lost... lol As if that would happen to me 😉

Nice watch

Die Uhr bietet alles, was ich brauche für wenig Gewicht und Geld.

Un producto de calidad y precisión. Elegante y funcional

I am writing this review after using it for last 7 days.I received the watch in 12 days from dispatch date. It was sent through ARAMEX courier , seller is from California. This model is not available in India. The packaging of Casio group is not at all impressive. Only a stand to keep the watch covered in paper box. In India, Casio watch comes in either hardy plastic box and for G-Shock in metal case. So I really don't find it impressive as it is a imported product , coming from USA. Now, about the watch: 1. Looks quite hardy and rugged one. 2. Illuminator light is great, the dial lights up in deep green and digit lights up separately in light green which creates contrast. 3. Made in China (Not thailand make) 4. Band is resin but I don't think its long lasting...let's see in coming years. 5. Band buckle is plastic made and not hardy one , I thought it would be in metal/steel like other company's watch or like Casio G-shock comes in resin band but the buckle is steel. Even cheap watch of timex provides metal buckle in resin band. But this band comes with plastic buckle and I handle it carefully (like not to wear it tight as during removal from wrist the buckle may break if u pull hard) 6. Time is showing accurate.World time and other basic features are good. 7. Alarm sound is a bit low than other casio watch. Snooze alarm function works great specially in morning when you find it quite challenging for waking up. 8. Now lets talk about the main features of the watch i.e.Digital compass and Temperature sensor : a. Digital compass is quite accurate. I checked it with my mobile compass too. No calibration is required. Don't calibrate it as soon as u get the watch. Check first with mobile compass or any other compass before calibration. b. Temperature sensor shows the body temperature so as many people said in previous review, you have to keep your watch open for sometime,then you may get correct temperature. But I can suggest you to subtract 3 to 4 degrees to get correct temperature when you are wearing it. Though it depends person to person for different body temperature but 3 to 4 degree is general.difference from correct temperature. 9. It is 200 meter water resistant and it really is.You can dip it in bucket of water or get into swimming pool. But don't operate the watch/press button as long as you are in water or your hand is wet. 10. Overall it's a good buy...the watch looks quite good and am satisfied. 11. no warranty in India/or outside USA but that's not an issue. I am using casio watches for last 5 years and I can say it does not malfunction within 1 year. It may shows up some problem after 3 years.
