Legendary watch. Unfortunately, however, it is unsuitable for anyone with a large wrist, due to the small strap.

Excellent for its price. Simple and functional. It makes you think that maybe the 1,259 functions of a smart watch are, in the end, just another source of stress.

And certain details make you wonder. For example, with one click I set it to beep when changing the time. I haven't managed to do that on the Apple Watch.

CON: Be careful, it is incredibly small by today's standards. If you have a large wrist, it will seem strange to you.

The classic all-time Casio that I have known since I was a child. I got it for my kid who is taking the lower exams and smart watches are not allowed.

The ultimate watch for the army!

It is waterproof and as light as a feather to the point that you forget you are wearing it. Additionally, it has an alarm, which is very useful because especially in the first days in several units, mobile phones are not allowed.

It is a watch that every man should have in his collection. Personally, not only did I enjoy it, but I also found myself many times in daily use setting aside watches worth hundreds of euros for this particular one.

Buy it without fear.

Note: It also has a small light so you can see the time in the dark. It is quite weak, but it does the job.

I got it because of work and nostalgia since I had it as a kid, so I wouldn't wear out my smart watch... the result is that I forget to wear the smart watch and it just sits on the nightstand.... Casio, a watch that will still work after 100 years ️

All good, the watch is as I expected, but the alarm sound is extremely low. To the point that you have to put it in your ear to hear it, that's why I removed one star. If you absolutely need the alarm, choose another model.

Extremely cheap, but this has nothing to do with its durability and usability. The only thing that might break is its strap, which, however, can be easily and very cheaply replaced. Its battery lasts from 2 to 5 or even more years depending on usage and can be easily replaced by the user with a small screwdriver. Classic Casio value.

Excellent and works perfectly. Just like 100 years ago. It fills you with memories and works tirelessly. Quality as I remember it.

it's small on the wrist because we are used to large watches as shown in the photo next to the band

After 1.5 years of operation, it remains impeccable and has not shown the slightest defect for the money it costs! I recommend it!

The fact that it has been in production since 1989 and still sells around 3 million units a year in the era of smartwatches, I think says it all. The epitome of simplicity and good Japanese engineering. It has all the functions one might need from a watch and does nothing more or less than what it promises (in fact, its water resistance is quite more capable than what Casio officially states). So light that you forget you're wearing it, cheap and proven to be reliable. In short, a legendary watch.

It's a pen! It doesn't break easily, very cheap, just what one needs for work

With two or three euros more, you can find a better watch... However, it is the most durable watch in the world for this money!! And the reason I chose it

Guys, I beg you, don't write reviews like it has a good battery, the time doesn't look good, etc. This watch is the legend of watches with billions of sales.

Classic. For daily use without worrying that something will happen to it. I notice some small delays in seconds when a lot of time passes since the last adjustment, but what do you expect for 16 euros?

Very good quality! I wear it daily for many months even in the bathroom and it hasn't suffered anything! Guaranteed!

Purchased for Military Service.

This little watch is very good. I need to see the time and set an alarm, and it does that perfectly.

Its night light is not very bright, but that's a minor issue.

The battery lasts for years, according to what it says, so logically for its cost, I won't change the battery, but the watch haha

I bought this watch for the second time for military use and the reason is its durability. It is a simple, classic watch that I don't worry about if it gets scratched or suffers some wear – it is exactly what I need for daily, tough use. Just like with the previous model I had, its quality and sturdiness are excellent.

This watch is comfortable on the wrist, beautiful, and adds style without being excessive. It is a timeless piece that fits well. Its simplicity makes it ideal for my military daily routine, during patrols, training, and even walking. For me, it is simply a reliable watch that serves its purpose, without worrying about its wear.

A timeless and everyday watch that you forget you're wearing. If you have a large wrist, it's not for you. But it's a watch that can spend a lot of time on your wrist

After 2 weeks of use, I will evaluate it.
On the positive side, the low cost, it is very lightweight that you forget you are wearing it. As for the accuracy of the time, it is too early to judge. Also, the glass has not scratched yet.
A major disadvantage is its small size, which gets lost on an average male wrist (the photos are misleading). The light is faint and barely shows the time only, not the minutes. The screen is very small, and anyone with a bit of presbyopia will struggle.
Overall, it is a watch that is now outdated, which is only worth acquiring for collectible reasons.

The Casio F91-W is a special case of a watch because essentially with just about €20 you buy an excellent watch for everyday use and not only! Of course, for some users it is considered "small" in size, however for medium-sized wrists it fits very well. As for the infamous night light that the watch has, I can say that it is satisfactory, adequately illuminating the screen; generally, both for the indicators and for the light at night, it’s all a matter of vision... that’s why I wouldn’t recommend it to people who cannot easily distinguish small letters.

Unmatched value, one of the classic designs and products that you simply can't find anything wrong with.

favorite casio. battery lasts for years, light is sufficient for the night, goes in the shower (I put it everywhere, even in the sea), has all the basic functions, I won't change it

Purchased for a diving watch and ended up wearing it a lot more on my wrist. Lightweight, you forget you're wearing it, great accuracy in time, price is really a "steal" and also brings a nostalgia for us born in the 80's. Worth it

Everyday little watch, it does its job, and even if I lose it or break it, it's okay..
Bought it to remember my youth

F91W, what can I say... One of the best models of all time. Classic, modern, retro all at once. Especially for us old timers who grew up with these watches, there's nothing better than wearing them again.
Next model I'm considering is the Casio Calculator.

Just amazing. Every flaw its has is beloved. You can never go wrong with the casio f91 w , its the perfect first watch in your collection and it’s suits everyone regardless if ur a student, a president or even a terrorist . God tier .

Everything is good with the watch, it's just that the lighting is completely inadequate.

the best for your military service
