Nice and practical
Nice practical watch to wear anywhere. Waterproof and will stay on. It’s easy to set up and change the timings - watch and familiarise yourself with a YouTube video. It’s lightweight and comfortable to wear. Be careful though when tying the watch around your wrist because if you do it too carelessly the little stick thing will snap off as it’s fragile. Other than that it’s quite durable. I misplaced it one time and hadn’t seen it for weeks. Turns out it was in the garden that whole time. Whoops.

Classic, comfy, reliable, and iconic !
I’ve owned a lot of watches over the years—smartwatches, “serious” watches, fashion watches—and somehow the Casio F-91W remains one of the most satisfying things you can strap to your wrist. It’s cheap, it’s light, it’s unapologetically plastic… and it’s also weirdly perfect. It is lightweight and easy to wear, keeps solid time, and has a ridiculously long battery life. The alarm and hourly chime are simple but useful, and the retro look goes with almost anything. Downsides: the backlight is basic, the strap feels budget, and it’s only splash-resistant—not for swimming. BUT, overall it’s an unbeatable everyday watch for the price.

Waterproof and Shockproof.
Classic. A few of these I have been through have had problems with adequate LED lighting to see the time and date upon press, but this seems to have been ironed out in the latest purchase. Being solid state digital, these are waterproof and shockproof for the lowest budget.

Cheap but so good
The watch not only looks great, but it feels solid, what for something so light it impressed me, forget I’m wearing the thing sometimes, and for what you get this is a bargain of a price, functionality wise lots of modes to choose from, and anything you might need is guaranteed to be there, especially happy to see they got the ability to switch between 24 hour and 12, as someone who lives in the UK much prefer the 24 hours one for sure, and although this thing is small it’s not a bad thing, I like it’s so light and small, could wear this for days without any issues, I don’t use it, but the alarm function seems solid, and you can toggle between all the settings, but amongst the alarm function options I prefer having it off completely, as I don’t like it particularly on any watch and makes it hard to wear in public spaces. Idk how water resistant this thing is, but it’s withstood the water it has gotten on it through the days naturally very well.

It’s exactly as described
This watch came on time and in perfect condition. Got it for my husband’s work. The alarm works well and is quite loud lol. He loves it so much I had to get him a silver one for his birthday.

Quality has changed, don’t recommend.
Would not recommend anymore. Have bought these for years and they’ve always lasted well and at such a low price can’t grudge requiring a new one every year or so. Recently I bought one in December which stopped working within 2 weeks and then bought another straight away thinking it was a one off, the replacement stopped working within a few days, completely blank screen unresponsive. Two watches not working in such a short time suggests there have been changes that reduced the quality. Seller said they’d refund or replace the second watch, which they have done neither.
