Amazing wrist watch
Bought this almost a year ago, although lost it a couple of months ago :(It's working like a charm, it's small so fits perfectly under a shirt and i love the combination of black and gold colours.Setting the time is as simple as it gets in electronic watches, it takes less than 30 secs.It's also very comfortable when you type in a laptop, as the small size doesn't bother you and the whole strap is plastic / resin, so as there are no metallic parts there's no danger in causing any damage to the computer.True, the strap is for people with average wrists (may not be the optimal choice for some men, but perhaps you can change the strap). Also, the light isn't the brightest, but gets the job done whenever you need it.In my mind it looks much more expensive (perhaps the colour combination helps) and although i have much more expensive watches (well, it's hard to have cheaper!) i always prefered to wear this one! :)For £15, it's like cheating.Only drawback is that the colour began "fading" around the corners, but that was hardly noticable if you didn't inspect the watch closely.I plan to buy this again when i place another Amazon order, although i have many more watches.

I really like these watches
I really like these watches, because of the look (I needed something to go with a black and gold ring my father had left me) but these watches are brilliant and amongst the watches I have are Rolex and Omega, not keen so much on Rolex after I read about the way they treated George Daniels, but Omega bought his co-axial movement. Anyway,I like the way you can set them to the exact second and of course the accurancy is first-rate, plus you can just press a button to go from AM PM to 24 hours display. I am not aware of any weight on the wrist while wearing the watch. It gives the time, calendar, stop watch, alarm and night light, so has everything I really need most of the time and the price is excellent. I am not keen on steel bracelet watches and I much prefer digtal to analogue number display. The resin strap watch combination reminds me of the Rolex Yachtmaster, so that is fine. Perfect purchase and looks great, a real bargain and you get a stack for your money.

The perfect watch for wise people. Anything more is pure vanity.
The only things to survive the apocalypse will be cockroaches and Casio F-91Ws. The watch collector's watch - smart, accurate, indestructible, cheap. Does all you ever really need a watch to do. Anything more is pure vanity. Be smart - buy one, buy them all. You know it makes sense.

Comfortable on wrist . It works . Retro cool
I love my watch ( silver face , black strap - classed as “white” on amazon)It looks smart enough when needed but also comfortable all day long and doesnt pull hairs on my arm like a metal strap .The light is not much cop but that reminds me of the 90s . Still great after a couple of years .

A wondrous thing
I love this watch more than my children. When I wear it, interesting people are attracted towards me. I could never afford one in the eighties, but now I’ve finally got one on my wrist, and it feels like I’m some kind of all powerful god of time. Good battery life.

Does what it says on the tin
I got this Casio watch to have a more precise, better fitted watch to keep me on track for my classes. This spiffy watch, which while not a Rolex or an Omega, lets me know exactly what the time is (down to the second!) and what today's date is--all I need to know! At its price point, I wear it all the time without worry for damage, and it looks surprisingly sharp considering the materials it is made out of. What more could I ask for?

Cheap and cheerful, but probably not for me.
With it being one of the cheapest Casio watches I've seen I picked this up in November 2021 for £18.65. The F-91W understandably feels a bit cheap given the price, with a simple resin band and apparently a resin casing too. The back is stainless steel, which is great.My wrist is small, but I struggled to get a comfortable fit with this watch. The band is the issue - I believe the most comfortable position would have been between the 6th and 7th hole, but obviously there is nothing in between. It ended up being a bit too tight or too loose for it to be comfortably sitting on my wrist. Also, to me it feels like the watch case is just too thin - it doesn't feel substantial enough. However, it is made to price.As for the timekeeping aspect, it excels. In two years' time sitting on the shelf it only drifted about 10 minutes. I'm no watch snob so I don't know if this is good or not, but for £18 I would've expected far more drift.I somewhat like the little light on the side, but I feel like it could've done with two LEDs instead of one, to light up the right side of the LCD better. The buttons are a bit confusing too - I had to read the manual originally and again this year to set the time.That, and I think I'm more of a fan of analogue watches in general, making this one feel just a bit off to me. I'm sure many people would love it - I like some of it, but not all. I think I'd go buy something else.
