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.

Extremely functional and convenient watch. I purchased it because I wanted to tell the time in class without having to pull out my phone, this watch has been perfect. It has not scratched and only lost 2 seconds of time in the month that I've had it. The material is durable and not uncomfortable. It is impressively lightweight and thin. Only flaws are that the alarm function is pretty limited and the light stinks. Other than that, highly recommendable for any time telling needs!

There's nothing bad I can say about the watch. Seriously. I'm a 16 year old kid (you know how reckless we can get) who has had this for I think over a year now, and I can honestly say this thing is REALLY DURABLE!! *How durable* you ask? I wear this thing to school nearly everyday, never having to worry about it. Yes, that means I travel with this thing very often. At school I sometimes even abuse my watch in front of my friends by slapping it on the table with full force to show them that they DO NOT wanna get slapped by this thing (it's just a joke; I would never hurt anyone unless there is very good reason since I'm pretty passive, but they're now aware I have a makeshift weapon with me at all times). I went to Cambodia last summer for a whole month, taking it across the ocean with me, swam in saltwater with it, and traveled most of the country. Surprisingly the airport security all 8 times said nothing about my watch, as it is related to being the official Al-Qaeda watch... something which is a fun fact to tell people. This thing is *still* going strong. It's clear as day to read, with very minor scratches on the face of it. The scratches are not even noticeable at 2 feet away from my eyes (even after the abuse)! The light it has is very long lasting as well, and is bright enough that you can use it as a very makeshift flashlight for things that are very close to you by facing the light away from you and pressing the button for it. It has helped me find light switches in the dark many of times. For settings things, it's very very easy. You may only need to look at the manual probably 2-5 times before you remember everything necessary because it's just so simple. If any buttons are broken it's a pretty simple fix as well; here's what I did: 1a.) Unscrew the thing on the back if you have the right kind of screws. If not, look for them on Amazon. They are I think a -2 Phillips. 1b.) Take out the screws very carefully and put them somewhere they won't be lost. They are very small, hard to handle, and easy to lose. 2.) Gently take out the rubber thing that covers the internal edges. Feel around if you don't see it right away, you will eventually. 3.) Grab a pair of small scissors, meaning the tips of the blade can fit into a small space. 4.) In the watch there are Signal Connectors, which look like small arms coming from the middle edges of the actual machine. 5.) Simply bend them perhaps 45 degrees toward the actual machine using the scissors as pliers. Make sure the button does not lay under or over the Signal Connector, only to the side of it where it can be pressed. 6a.) Repeatedly press the button time to time to test if the function of the button is restored. 6b.) Adjust the angle in step 5 as necessary. You want to bend the Connector to the point it doesn't always touch the Receiver (the thing that actually performs the function of each button), or you will have a frozen watch. 7.) When the button finally works again after some toying around, put the rubber thing back in, pressing every corner back into place, and then screw the case back into place very tightly. 8.) Drop the watch in water before you wear it to ensure you won't get electrocuted. The alarm has gotten me up most of the times, and I'm not a light sleeper. Although I'm also nowhere near a heavy one. The inaccuracy can seriously vary... once it was off by a minute in a week. This week it is only off by about 7 seconds. Really, just sync it weekly and you should be fine. The watch is very good if you just need a very good idea of what the time is. Thanks for reading! I would definitely recommend this watch and perhaps will buy it again if the dang thing finally breaks!!

I had been looking for a relatively cheap digital watch, preferably from Casio, as a simple watch to start the New Year off with. When I searched "casio digital watch" this was about the second product listing, so I knew it had to be a decent watch. I had worn it for a day or two and have since replaced it with the [insert link here]. Here is my review of the Casio F91W-1 and an explanation of why I replaced it. --------------------------------------------------------------------------------------------------- Design & Build: For just over $10, this Casio has great build quality and a cool retro design. In fact, the Casio F91W has been produced since 1991 and even has its own Wikipedia (https://en.wikipedia.org/wiki/Casio_F-91W) page! The design of the Casio is simple and classic and is probably one of the reasons why this watch is still successful after 25 years! The watch is very thin, - only 8 millimeters - especially for a digital watch, which is about the same thickness as an iPhone 5. The watch face is made of plastic and is not recessed into the body, meaning that while it is flush with the casing it can be scratched easily. The casing of the watch is made of resin which is pretty standard in most digital watches. The band is also made of resin and is comfortable enough for a $10 watch. One complaint that I have about the watches build quality is the material of which the band buckle is made of. The band buckle is made of ordinary black plastic which I can see breaking in a year or two. While I can't vouch for the longevity of this watch, I can almost confidently say that that plastic buckle will be the first part to break. Other than that, the watch features nice easy-to-press buttons which stick out from the watch a millimeter or two. The buttons are very easy to press, which can be both a good thing and a bad thing as they might be pressed accidentally. The top left button activates the display light which is very weak and only lights up from one side of the display, meaning that the left part of the display is kind of bright while the further you get to the right side of the display the light dims drastically. This seems like one of the areas Casio had to cut corners with in order to cut the cost, however, it is only a minor complaint with a $10 watch. The light shines a green light and only turns on while the button is depressed, which is kind of annoying. Digital watches I have owned in the past stayed on for a few seconds, but again, this is only a minor complaint with a $10 watch. Finally, the Casio features water RESISTANCE, not waterproofing, therefore I wouldn't go swimming with it, however, other users have reported diving with it so the decision is ultimately up to you. Overall, the Casio F91W features a simple and timeless design, as well as pretty good build quality for $10. The display light has some issues and the watch is only water resistant, but these things don't matter too much in a $10 watch. --------------------------------------------------------------------------------------------------- Fit: I have around a 6-inch wrist and this watch fit great. I used a hole more towards the end of the band away from the case and it fit comfortably while not being too loose. The watch is very light and once it is on you almost forget it is there. The case is also thin and doesn't add much bulk to your arm. For me, the watch face was a good size proportionate to my wrist. It might have been a little small for my liking but it definitely didn't get in the way. Overall, I am happy with how the F91W fit on my wrist. --------------------------------------------------------------------------------------------------- Overall: This watch is a great watch for the price. While I can't vouch for the longevity of this watch, I can say that it features a great design and decent build quality, as well as a good and comfortable fit (at least for my wrists). To conclude, if you have a bit over $10 to spend on a digital watch, you really can't go wrong with the Casio F91W. --------------------------------------------------------------------------------------------------- Pros: - Classic simple design - Decent build quality - Comfortable - Thin and light - Easy-to-press buttons - Good fit for me - Accurate time-keeping (Casio claims that the watch is accurate to ±30 seconds per month due to the quartz movement of the watch) Cons: - Weak plastic band buckle - Easily scratched plastic face - Weak and poorly designed display light - Buttons may get accidentally pressed - Only water resistant --------------------------------------------------------------------------------------------------- Why I Replaced it: Even though the Casio F91W is a great watch for the money, I decided I wanted something a bit nicer, even if it meant spending a little bit more money. After browsing Amazon for other Casio watches, I came across the G-Shock G100-BV Men's Black Resin Sport Watch . The reason why I replaced the F91W isn't because it isn't a good watch, instead, I replaced it because I wanted something a little nicer with a more rugged design. To conclude, I replaced the F91W not because it wasn't good, but because of personal preference. --------------------------------------------------------------------------------------------------- If you found this review helpful I would appreciate it if you clicked the "helpful" button below this review. Thanks!

I’ve been wearing this watch every day for about five months now, including to work, and it has held up great. I really like the sleek, simple look. It’s versatile enough that it looks good with a casual outfit but also works well with a uniform. One feature I use all the time is the timer for my lunch breaks. It makes it easy to keep track of my time and make sure I stay on schedule. After five months of daily wear, it’s still working great and has been very reliable. Definitely a great everyday watch, especially for the price.

You really can’t beat this watch for the price. It’s incredibly lightweight, comfortable enough to forget you’re even wearing it, and the battery lasts for years. It keeps accurate time, has an alarm, stopwatch, and backlight, and the classic retro design never goes out of style. Whether you’re wearing it every day, working, or just want a reliable no-frills watch, this is one of the best values you can buy. Highly recommended.

Pros Classic, timeless design that never goes out of style. Lightweight and comfortable for everyday wear. Easy-to-read display with useful features like a stopwatch, alarm, and LED light. Reliable and accurate timekeeping. Excellent value for the price. Makes a thoughtful gift for a wide range of ages and styles. Cons The LED light is fairly basic. The resin band may not feel as premium as other materials. Overall I purchased this as a gift, and it was a hit. It's simple, practical, and has that iconic design that never seems to go out of style. For the price, it's hard to beat the reliability and functionality you get. A great gift and an easy recommendation. It's great for everyday use, combines with anything, it was an amazing gift my bf loved it and he looks great with it. Also the strap is really cool

dit horloge is een 'must have' voor elke horloge liefhebber. ik laat het horloge in de originele verpakking.

El reloj de siempre, un auténtico todoterreno. El último ha durado unos tres años, utilizado por persona que se dedica a tareas del campo, uso intenso en condiciones extremas y aguanta muchos golpes, líquidos... Siempre repite.

Comprei esse relógio já faz quase 1 mês (chegou dia 31 do mês passado) e minha experiência com ele foi muito boa. Ele é um relógio completo, por um preço muito barato, o valor dele não condiz com preço (quero dizer que poderia ser mais caro) pois ele faz o "arroz e feijão bem feito". Tem cronômetro com marcações, data do mês e da semana, alarme e a luz noturna que é a única coisa que deixa a desejar, mas consegue cumprir seu papel. Sua bateria dura 7 anos, mas se você não usar tanto a luz e cuidar bem, pode chegar a mais de 10 segundo relatos. Uma das funções que mais gostei também, é o "bip" que ele dá a cada hora que passa, da pra desativar pra quem não gosta mas pra mim esse barulho faz diferença. Ele é 100% original e tem até os dois eastereggs, um deles apertando o botão direito por alguns segundos e então ele exibe o nome "Casio" e o outro o outro apertando todos os botões ao mesmo tempo fazendo com que todos os números sejam ativado. E também ele é de um tamanho que vai agradar tanto quem tem pulso fino quanto um pouco maior, no meu braço ficou exelente. Ele fica bem com praticamente qualquer roupa, além de ser retro e muito bonito, é também um ícone da relojoaria! Simplesmente o relógio mais vendido de todos os tempos. Gostei muito dessa compra, até porque peguei com desconto kkkkk mas enfim, valeu a pena cada centavo.

For a gift

It has all necessary functions, fully satisfied….
