Simple and great!
I loved it! Its beautiful, lightweight design and compact body make it comfortable to wear on the wrist. Unlike other watches, thick-case watches have always bothered me, but this one was a game-changer. I highly recommend it. Setting it up was easy, the price was good, and the screen is readable! 💯

Su calidad y durabilidad
Title: The Classic Casio – Perfect Daily Watch!”You simply can’t go wrong with the Casio F91W. It’s the definition of a reliable, no-fuss watch. It’s incredibly lightweight and comfortable—you barely notice it on your wrist.All the essential functions are there: alarm, stopwatch, and a light for checking the time in the dark. Plus, its water resistance is perfect for daily life, like washing your hands or getting caught in the rain. A total classic and an absolute bargain!”

Amazing Watch, except a few things.
This watch is absolutely AMAZING! It looks very unique with its own design but still manages to look nice no matter the occasion. The features are nice, I like the stopwatch but the alarm personally isn’t loud enough for me, but that doesn’t matter because most people don’t use their watch for alarms. I haven’t worn it enough for durability yet but it with stands scratches pretty well. The band is also very comfortable and easy to adjust. It’s the perfect watch if you just want a watch not nice enough to be a rolex, but not smart enough to be an apple watch. Just time! And time is does incredibly well, it’s very reliable, looks nice, and I forget I’m even wearing it.Okay here are the not-so-good parts, (this watch is perfect but here’s what the picky people should look out for)The few times I need to click the buttons they feel weirdly uncomfortable to press and hard. Also, the backlight is VERY dim, I know it’s too small to but a full backlight but atleast more than one LED. I have to squint to see it and the oppisite side you can’t see anything. Doesn’t come in clutch the few times I need to use the light.

Great watch, easy to setup
This is a really fun and functional “throwback” watch! It looks just like the digital watches when I was a kid in the 80s. Got this for my son for travel because it doesn’t look expensive, so hopefully it won’t attract any attention. It’s great that it’s SUPER easy to use. My son was in a hurry and asked us to set it for us and I was pulling out the instruction manual, ready for a complicated setup but my husband grabbed it and had the time set in 30 seconds. And this is a great price for a good watch that is also water resistant!

It’s a good watch but the light is so dim I can’t read it in the dark
Well, it’s a fine enough watch for the money BUT, the light is so dim I can’t read the time in the dark. I dont feel like returning it though, so, four stars. I dont know if that’s ..an accident or if they cut quality. The battery doesn’t seem to be low, so it’s just a very dim light. The instructions made me want to pull my hair out so I googled how to turn the alarm on and off, that worked fine.

A great digital watch for a STEAL!
A great casio watch for a great value. Easy to read with classic retro looks. Pretty small format watch perfect for my 15yo daughter. Easy to set up; has more than enough features for this price point. Has the casio time accuracy we expect!

Casio F91W For the win
As someone with small wrists (about 7 inch), I never really wore watches because most men’s watches were just too large and just didn’t look right on my arm. This watch is small and actually looks the “correct” size on my arm. I’m instantly a fan of this watch, and I am already looking at getting a couple more of these simple Casio models. I like how most of these watches are basically the same watch in terms of features and controls. Time, date, alarm, stopwatch… That’s really all I need from a watch, and the price point can’t be beat. Why not get a few!

Solid classic watch
It’s nice to get a very good watch for 20 bucks. I’ve got quite a few meh watches that didn’t last long for the same cost. Yes the back light is close to useless but it just works. I have a large wrist so it barely fits with the watch band but I see why it’s a classic that had sold 100 million watches.
