Review: 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.
Review: Excellent Value Timepiece - I have bought this same make & model of watch for something like 20 years or more, this latest (due to losing the last one on holiday) being my 4th. I did change the battery on the first (after 5 years+) but have not bothered since, as the cost of a battery was a significant % of the cost of a new watch - a bit like changing a car when the ashtray gets full!!! But up to personal choice. I had one where the rubbery strap split and broke after about 4 years- but again the cost of a strap outweighed just getting a new watch, and besides, I do not personally like to wear a watch on my wrist, just keep in my shoulder bag/trouser pocket!!! (so that one with no strap lasted me a further 3 years, before the battery died) So, if a cheap, inexpensive, accurate (20 seconds slow after 1 year) "throwaway when battery/strap broken/stopped" style of watch is what you are looking for - then in my opinion this one is a good choice. Oh - and finally, yes the light at night is not very bright (I have to also pop my reading glasses on), and the alarm is not very loud (but I find good enough as a gentle reminder for 20 seconds) - but don't a lot of people these days also have mobile/cell 'phones that do all that (and tell the time!).....so good enough as a secondary/auxiliary time piece in my view, with also handy stopwatch/time counter function.

## Questions & Answers

**Q: Hi,  I'm female. Can I buy this watch?**
A: No unfortunately not, the timer is fuelled by the testosterone emanating from the male wrist. It won’t  work on a lady.

**Q: Mine arrived with the Battery already started. I didn't want this as it a gift for giving after being stored.**
A: The battery will last for a decade or longer. The strap will break long before then. And a decent replacement will cost more than the watch.

I have bought this particular watch repeatedly over the years. Initially I replaced the straps; in the end I just gave up and bought a new one each time. I stopped wearing a watch on my wrist when I stopped working, 8 years ago; by that time I had accumulated at least 6, all still working fine. My wife normally carries 3 around in her handbag (don't ask!); I have another 3 scattered around the pockets of various pairs of trousers. The first couple of batteries actually ran down in close succession about a week ago. I estimate that I bought the watches in question getting on for 20 years ago.

And after 20 years, a new battery cost about 50p, and took maybe 10 minutes to fit (only tool required was a screwdriver suitable for tightening the screws on spectacles).

**Q: Does the watch come with a warranty?**
A: I never thought to ask. At that price, I would doubt it. I have had three of these to date. None of the watches has ever failed; it's the strap which breaks, and a new one is almost the price of the watch.

**Q: my wrist circumference measures 8.5 inches - will it fit me?**
A: Yes.  Range is 5.5 to 8.5 inches.

### ⭐⭐⭐⭐⭐ Awesome little watch...
*by M***P on 5 September 2022*

I bought this watch for times when I was doing outdoor rough and tumble stuff. I have other watches for dress, but this little watch was a real surprise performer. It has been totally reliable and worked well after all sorts of abuse. I cannot recommend this enough. For the price you pay it is an absolute steal, you won't be disappointed. It puts a Seiko I have to shame. If I have to mention a downside, I'd say getting you're head around the buttons can be rather interesting, and the back light isn't great. But the positives easily outweigh those negatives. I don't know how Casio can produce such a little gem for such little money. One of my better buys.
