    Light is dim but not worth taking away stars. This watch is functional, super lightweight and tough for the price. Will be getting another when this one has its day. Very resilient and very water proof. I work with large metal concrete bins and it’s slightly scratched but still great

    I’m not a big watch fan so I got the most simple one. It’s really easy to read and really easy to set up too. Although I wish it came with a manual but thanks to YouTube I was able to set it at the exact time and date. It’s strap fits pretty snug on my wrist and it doesn’t feel heavy at all, it’s not too bulky either, it’s a perfect watch to wear to work. It doesn’t get in the way at all, especially if you work in the food industry. I might just be the best watch I own.

    I wanted a basic watch – not a smart watch or anything, just a digital watch that displays the seconds. The date is also a nice feature. This is very handy for me as I work in a time sensitive environment. It has the option to display AM/PM as well as a 24 hr clock.I take showers with it on every morning and so far it still works fine. Setup is pretty easy and the instructions that come with it are OK. The wrist band is comfortable enough. The built in light is not that strong but it is good enough to read the time in the dark.

    Jumped in the ocean with a sun shirt on forgetting I still had the watch on. Got home and took my shirt off to shower and noticed I had the watch on. I got a a bit concerned but looked down to see the watch was humming along like it hadn’t just been in the ocean for an hour. Im now sitting here five hours later and it is still working perfectly. These are made well.

    First: What Amazon calls “white” is actually the silver model. Do not order a “white” one expecting a white case.To the review:This watch is good. My usual hesitation with digital watches is that they are extremely overcomplicated, with alarms I do not know how to shut off (or set), etc. G shocks, Suuntos, etc, are all good watches if you need all their features. However, I do not. I expect most people do not. Most people need the time and date, and the Casio does this, and it does this well.I also like 24 hour time, and this is only possible on digital watches, unless you track down a Soviet submariner watch, which I don’t want to do.This is the Glock of digital watches. Like a Glock shoots every time, and nothing else, the F-91W tells the time, date, and not much else. It has an alarm and a stopwatch if you are into that. They are unobtrusive features if you do not go in for them. The buttons do not get accidentally pressed, the housing is very low profile.I have only had this for a couple of days, so we will see on durability, but anecdotally these can take a lot of abuse.This would also be a good first watch for kids or for a elderly person who just wants a thing that can tell time.The LED light is a touch dim. According to how good your vision is, you might not be able to see the minutes and seconds, but you will probably be able to see the hour.

    There are simply too many reviews of this watch. So instead of a review I’d like to share with you a conversation I had the other day with one of my co-workers.Co-work: What’s that on your wrist? Did you borrow that watch from you 10 year old son? It’s so small and cheap looking. I didn’t think you ever knew how to read a LCD display.Casio F-91W Owner: It’s a Casio F-91W, and no I didn’t borrow it from my son, but sometimes I let him borrow it from me. I know that I typically, prefer analogue watches with a mechanical or automatic movements. I did need to read the instruction manual I figure out how to read the digital display. Once I figured out that the colon on the display is separating the hours (on the left) from the minute (on the right) and the smaller numbers on the far right represent the seconds; it’s actual easier to read that the 3 hand analogues.Co-work: So, why did you buy this watch? It doesn’t seem to fit in with your Seiko 5, Orient, HMT, Citizen Eco-drive or that Chinese knock-off of an expensive German watch you can’t afford, that you typically wear to the office.Casio F-91W Owner: It’s nothing like my other watches, but this watch is one of the great classics. This model was first made in 1991, and was the smart watch of its time. The features and price-point is also unbeatable. I got it specifically because I am going on vacation to the beach and I wanted an affordable watch to wear of the beach and in the pool. This is proven technology; this model has been manufacture for over two decades and it’s almost bombproof.Co-work: Doesn’t WR mean Water Resistant; like splash and rain resistant only. I thought you need at least a 50m or 100m rating to take it swimming.Casio F-91W Owner: You are completely correct, and completely wrong. A watch worth worrying about needs at least a 50m or preferable a 100m rating just for swimming on the surface more or less. Personally, I wouldn’t take any of my other watches swimming on purpose, even though some of them have a 100m rating. However, this Casio is very modest in cost and I consider the manufactures water resistance rating is very under stated. Sure, if I ruin this watch swimming, the manufacture going to tell me to fly a kite, if I made a warranty claim, but this is a ten dollar watch. If you have ten dollars to wager, like I do, throw caution to the wind or perhaps dive in head first with it. It’s a lot like jaywalking, it’s not recommended, but you not trueing living your life to the fullest if you follow every rule. I sure a G-Shock with 200m water rating is manufacture with more seals and offers better water protection, but I also think that the water resistance rating is partially just marketing to separate Casio’s $10 watches from their $100 watches. I’ve taken this watch in the ocean and dove in swimming pools with no problems. I’d recommend not pressing the buttons when it’s wet, as well as not being a cry baby if you ruin it, but this watch is suitable for swimming in my book.Co-work: Wow, what a risk taker, they must be paying you too much, if you have ten bucks to risk like that. So you say it’s was the smart watch of its time back in the day. What’s so smart about this watch?Casio F-91W Owner: Well for starters, a day-date complication with annual calendar, that only needs to be corrected for leap years. It switches between AM/PM and 24 hour format with a single push of a button. It has a hourly repeater that can be turned on and off. A stopwatch function, and am alarm. Did I mention it has a very dim light, and I believe it was y2k compliant nearly a decade in advance.Co-work: Wow, I think my iwatch can do all that, but I don’t know how to. I also paid a lot more than you, and I can’t take it swimming. How about battery life? Where’s the charger plug? Is it self-winding, like you Seiko 5, and going to die after a few days off your wrist? I know for sure that in 1991 there was no such thing as wireless charging.Casio F-91W Owner: It’s much for low tech then wireless charging, or self-winding. It’s powered by a replaceable battery. Casio claims 7-years on a single battery with no daily recharging required. It’s more likely that the strap will break, before the battery will need to be replaced. It doesn’t need any sunlight either, some people claim to get 10 years on a single battery, it really depends on how frequent the light and alarm functions are utilized. In theory you could hide out in a cave for years without worrying about charging or replacing the battery.Co-work: Hey, one more question. I know you are married, but ascetically speaking, do you think I watch like this would be helpful in attraction women? It’s kind of ugly looking.Casio F-91W Owner: Well my friend, with you ugly face and abrasive personality, if a woman takes the time to look at your watch, she’ll be excited to see a practical watch on your wrist. Well unless she’s a gold digger type, but you don’t need that. Any women that can’t appreciate a classic watch like this doesn’t even desire to go dutch at McDonalds with you. However, for you, I’d strongly recommend the Casio CA53W, if you want a line of highly desirable ladies wanting to go out with you. If you wear a Casio CA53W and a lady starts a conversation about your watch, you’ll need to take her somewhere nice, like a sit-down type restaurant, and pay the whole bill, and she’ll surely want a second date when she see you generously calculate 18% gratuity with your calculator watch.

    Tech is kinda invasive, ngl…which is why I’ve had an analog watch for the last two years. But I wanted something that had an alarm on in, was low key, and had the bare necessities of a watch (going back to those good ol’ days, ammiright?). I was recommended this watch by a friend and I wasn’t really sure if I’d like it, but ya know, it’s not too bad! It’s minimal and cheap, but doesn’t feel like it’s one of those Walmart watches. I really like how it feels on my wrist and it’s just plain convenient. Not to mention the fact its super easy to replace if anything happens to it.

    I’m over big, bulky watches. I’ve got my Suunto and a couple G-Shock watches. I still wear them, still love them, but mostly I just want a watch that keeps nice, precise time, doesn’t stand out from my wrist 3/4 inch and hopefully looks juuuust a little dorky. I’m also cheap. Waterproofness is important to me. I work a desk job. I commute by bus or train- watches help with that. I like to go on a run a couple times a week and wear a watch. I don’t sleep or shower with my watch on unless I’m camping or in a hotel. I like digital over analog because I kind of like to know exactly what time I think it is and I only ever estimate when I’m reading an analog watch because I’m lazy. Also, when I’m in a meeting or I’ve been pinned-down by someone I don’t want to talk to and I want to know if this really is taking forever or if my perception of the passage of time is just being warped- it’s easier to sneak a peek at a digital watch and get a precise read. I realized a few months ago that I really am just as happy wearing a $15 Casio as I am with my $250 Suunto and that most days I don’t need to know the barometric pressure. Some days, yes. Most days, no. But I like having a variety of watches (including the Suunto, which is fabulous). And I like to choose which watch to wear each morning. That’s fun for me. Recently I got on Amazon and ordered a bunch of new cheap Casio watches. I got four new watches for $52. I think Timex’s are over-priced. That’s how cheap I am.Casio W-800HAV ($20-ish) Digital Black. My eight-year old son and I each got one of these watches for Christmas 2016. We both love it. We both have other watches but wear this one the most. It has a fairly low profile- doesn’t catch on pockets or shirt sleeves. I love the light- it looks stupid, like piddly. But it actually lights the face well. I go jogging at night sometimes. The light works well enough for me to see how slow I am even while I’m bouncing down the road. And it’s got “Dual Display”. I don’t know what else to call that. It shows the time on one part of the screen and at the same time it show the stopwatch numbers. Nice to keep track of both. Or, If I’m out and about, I’ll set a stopwatch when the train goes by because I know that the train comes by every 15 minutes. So I can see when I’m coming up on another 15-minute mark and also see the time on the sub-display.Casio F-201WA ($10.47) Digital Black. Comfortable. Lightweight. Easiest buttons to push. Good light. I like that it has countdown timer and lots of alarms. I miss being able to see the time when it’s in stopwatch mode like I can with the W-800HAV and the WV-200A.Casio WV-200A ($40-ish) Waceceptor Digital Black with chrome and red. Looks good. Like the steel case. Good protection for the glass. Relatively heavy. A liiiiitle too thick. Really nice buttons. Great electro-luminescent light. This one is the only watch of the group that you can set it so it doesn’t beep every time you push a button. I really like being able to turn the beep off. Sometimes I like to set a stopwatch in a meeting so I can see how long somebody is going on with some bullsh*t. Strangely, timing somebody’s bullsh*t is a nice distraction from the bullsh*t. But I don’t like my watch to beep when I’m doing pushing buttons. “Dual display”- you can still see what time it is when you’re in other modes. Countdown timer is nice and many of my other watches don’t have one. I don’t give it extra points for the whole Wave Ceptor thing. Doesn’t add any value for me and it kinda sucks battery. This watch has been on my wrist for a full day of snorkelling and handled it beautifully. I live in a land-locked state, so when I get to the ocean, I’m in the water ALL DAY LONG. I can’t dive deeper than maybe 20 feet, so it’s not a serious test for a watch that says it’s good to 200m. But if you’re diving to 200m and time is critical, you’re going to spring for something more than a $40 Casio. (I love you, Casio).Casio HDA-600 ($14.79) Black Analog. Not the most comfortable. Kinda squeezes my wrist from bone to bone or flops around a bit. I dunno, it just fits weird. YMMV. Love the face protector. Can’t wait until it starts to look a little banged up. Glowy dots on the hands aren’t really impressive. Date window works perfectly. Looks tough but it’s probably not. I like it a lot.Casio MQ24-7B2 ($14-something) White-faced Analog. Incredibly light. Truly forget that you’re wearing it. Easy to read. No date window. No lumi. Nice, simple and never catches your sleeve in a dress shirt. Yes, I’m fancy. Some people are smart enough to read an analog watch that doesn’t have numbers on it- just dots. I’m not one of those people. I screw it up enough when there’s numbers. This has numbers. I like numbers. Haven’t tested this one for waterproofyness. Casio only says it’s water resistant. I hardly ever do underwater demolitions anymore.Casio A168W-1 ($16.15) Stainless Digital. I love / hate this watch. I don’t know if Casio was really trying to make a watch that looks fancy but it’s really a dork-bomb, or if they we’re going for dork-bomb as their aim. Either way. This watch is a stunning success. I think this watch is the pinnacle of nerd-swank. 1980’s wannabe stockbroker, cool old guy who doesn’t give a sh*t, little bit of silver under the sleeve to catch someone’s eye- oh wait it’s a friggin Casio digital. I mean, it’s chrome-plated PLASTIC for crying out loud. How awesome is that? I love all of that. Love it. It’s got the Illuminator light, which works great. Clock, date, stopwatch and alarm. No countdown timer. The metal band is not comfortable. It’s got edges and it pulls on my arm fur. Clasp works great and it’s wicked-easy to adjust. Slips under a dress shirt easily. Again: super-dorky. Makes me smile every time I put it on. Then wince when it pulls the fur.Casio F91W-1 ($11.35) Black Digital. I like this watch a lot. It’s super thin. Very lightweight. The light looks stupid but it works well. The buttons are easy to hit. It ranks pretty high on the ‘Dork’ scale. People recognize it. Hold that one button down and it says CASIo. It’s great. Proud to say I’ve never worn this watch along with flannel and a beanie. Never.

    No complaints but it tends to slide down my arm over time lots of notches , the light isn’t that bright but you can read it in the dark the alarm feature is quite loud which is good for me.

    The F-91W has a couple of advantages over its bigger G-Shock relatives like the DW-5600E. Its tiny case size and weight make it easy to forget you’re wearing. For small to average wrists, this watch should wear just fine. It will be too small for an 8 inch wrist or larger. The 8mm thick case will easily slip under long sleeved shirts and jackets when many G-Shocks won’t. It’s also tough enough for probably 95% of people. I haven’t managed to to break the watch and it survives lap swimming with no problems (even when its not rated for that at all.) But on the other side, the G-Shocks are rated for far better shock and water resistance and the materials quality are much better (and you’ll notice immediately when you handle them.) You will get what you pay for.The buttons are exposed on the side and that makes them extremely easy to operate. Once you memorize the layout, it’s extremely easy to set a quick alarm and switch the hourly chime on/off. If you prefer 12/24 hour time in airports or train stations, you can easily switch with one button press. The alarm volume is actually pretty decent as well. It’s not going to wake a really heavy sleeper, but it’s louder than most G-Shock models. Test it and see if it’s loud enough to wake you at home before relying on it in travel situations.A lot of people complain about the small, weak micro LED light. I get that. But it’s a compromise that keeps the case thin at 8mm. When you use the improved full-screen LED illuminator or EL backlight tech, the thickness of the watch has to increase. But the micro LED light actually does its job pretty well in actual darkness. Even if your eyes aren’t adjusted to the dark, you can easily see hours and minutes with it. But if a bright light is important to you, spend a little more for the slightly bigger F-105W.The watch’s weakest aspect is the band. The resin is cheaper than a G-Shock and it lacks the curved lugs that help it wrap around the wrist. Chlorinated water from pools, sweat, and salt water will all weaken the resin over time. Over-tightening the band will stress it more too. To make the band last longer, rinse sweat and salt off the band and dry it at the end of the day, and wear it loose enough to fit one finger between the band and your wrist.All-in-all though, the F-91W is an absolute winner if watch thinness and alarm/hourly chime are important to you. Highly recommended.
