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.

My Timex Inronman digital finally gave out on me after 7 years of wear and tare. I had no brand loyalties and wanted to find the most functional watch I could get for the price. My only concern initially was the watch's appearance, as I work in a profession that does not require a metal chronograph, but a nice looking watch is appropriate. This watch is exactly that - the face is not too big and the 'light blue' finish is just subtle enough that it does make the watch seem gowdy. As for its features, this rating would have been a complete 5/5 had it not been for three main issues (all of which have been addressed by other reviewers): 1) the temperature reading is not accurate if the watch is on your wrist and, subsequently, it must stay off the wrist for about 20 mins to get an accurate reading. Now, is the everyday user going to be using the compass and temp features on a regular basis? Probably not, and this should not be a limiting factor in my opinion. My compass works great though! 2) In order to view the watch face, you must look at it from a nearly perpendicular angle, meaning as I am typing this review with the keyboard situated well underneath me, I cannot read the time unless I turn my wrist and face the watch at my head. This was different on my Timex, but again not a huge issue. The read-out on this Casio is really well done though; big numbers and easy to interpret functions. 3) That pesky light feature on stays on for about two seconds. My only "real" functional complaint, but not a massive operational problem. Other than that, I could not be happier. The band is comfortable and the watch is incredibly light weight for the mid-range size it is. The band fastener piece is oversized so the band is quite snug when in place, a great feature. The watch was delivered by Amazon in a bubble-padded, manilla envelope and not a box, in case you were curious. The instruction manual is small, so go online and view the PDF version for a much easier time setting up the watch. I am highly satisfied with my purchase, and I saved about $50 compared to a Timex Expedition which was my second choice...

My son wanted a watch because all his friends had one - so this was more of an impulse purchase for him. At first I wasn't sure about buying on Amazon so we show roomed around town to look at this watch at retail outlets first to see if this is something he really liked and wanted and to ensure that it would not look too big or small on his wrist and that the enthusiasm for the watch was still there after a few trips. It was. After trying the watch at a few retail outlets and seriously considering buying it offline we noted the price in most cases was between $25.00 and $45.00 more than online and though there were a few negative reviews we decided finally to buy it online. I'm an Amazon Prime member and the watch came within 2-days just as it said it would. It was well packed in an outer box and the watch came in full retail packaging including the original manual. The first thing I did was to ensure it was a new watch and not something someone else had returned. I checked the screen, and back of the watch for scratches - none seen. Checked the band for any obvious usage like worn lettering and such - but of course, nothing of the sort. I was 100% satisfied that this was new and not a refurb/repack or anything else. As with most watches you do need to read the instructions to set the date/time and other features of the watch. The manual is an easy read and setting up the various items like date/time, world clock, and compass were pretty easy. The watch has come great features: - Big, bold and easy to read display. Although my son has great eyesight it's always nice to have a watch where the numbers are easy to read. The date and day is slightly smaller but the main display shows the time is large and bold and just below that is the seconds. - Stopwatch. My son started playing soccer and liked helping his coach, so the stopwatch was great so when they ran mini-races he would use the stopwatch to time the other kids. He also used the stopwatch to time himself doing his chores in the house! - World time. Not sure why he liked this so much, but he liked the world time feature. Many of his cousins live in Africa, so his world time is set accordingly. - Timer - again a feature that I didn't think was useful, but he liked it. - Alarm - LOVE this feature on the watch! Previously we would have to wake him up, but he sets the alarm himself and actually wakes up to it. - Compass - something that he won't use often but is a nice feature on the watch. Whenever we've gone out he'll set the compass to see if it matches what's shown in the car, to date I don't think it has ever been off. As you move it does tell you in great detail how many degrees you are as well (for example 33.4 degrees NNW). The size of the watch was perfect for his wrist - I bought this a couple of years ago so he was around 8 at the time. Initially it looked a little big for him, but after some time it seemed to look OK. I suspect it was just not seeing a watch on him until that time. He was never a watch person as a toddler so never got him even those kids Mickey Mouse or superhero watches. The watch edges come up over the face making it very difficult to scratch the face of the watch. I've noticed a few small, minor scratches on it but that's from banging it against something. They are definitely not visible. There are some scratches on the back as well, but again nobody looks at the back and the main reason for these scratches are because he leaves his watch in his drawer along with everything else in it. I actually liked the strap on it, initially I thought that we would have to replace it but it has held up very well with no cracks on it at all. The strap is not cheap plastic but quite a strong rubbery texture to it. I also worried that he may be allergic to the strap but no issues at all. The only noticeable wear and tear is on the strap where some of the lettering has come off, but on the face of the watch none of the lettering has come off or faded. He really hasn't tested the watch to the 200m depth but has gone swimming and in the hot tub with it on and hasn't had any problems. He's taken the watch to school and several adults have commented on how sharp the watch looks. The Casio SGW100-1V is a great watch for adult or child over 8-years of age. We are definitely very happy with the watch and would not hesitate to recommend this to any parent who wants a first watch for their child.

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. I will try wearing the watch and then recalibrate with my body temp. I am not sure if that will work correctly. Another small nice feature is the double beep once you hit the main Time screen. That means you can quickly change modes without looking to get back the the Time mode. A few very minor things that casio should have adjusted on this watch: They should have made the compass feature delay longer. I think it is set for 10 seconds. But by the time 10 seconds has passed I have only been able to adjust my body to the direction. Then I have to push it again to get another reading. I see no reason to have it delayed at 20-30 seconds. And then push a button if you want to see the clock. The alarm needs to be louder like others have pointed out. The back light needs to be at least 5 seconds. Not 1-2 seconds. The watch face is a tad large, however that is the IN thing right now with watches. Finally it would be nice if the bezel would rotate so you can adjust it for the compass. Overall for the price and features I have not found another watch that is better. I did a lot of research on every brand and prices. I wanted a watch where I would not be heart broken if I lost it.

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.

Great Casio. Worth it.
