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: How are they charging $10 for this $3 watch from 1990?**
A: Anything that was $3 in 1990 is now $10.  Back in 1990 gas was $1.16/gal.  The average home price was under $150000.  As time moves on prices go up.

**Q: Does the count down timer be set to seconds?**
A: No countdown timer. Look at Model F201WA-1A for that feature.

**Q: how far in depth is the water resist**
A: If you want to be absolutely safe, get the Casio MRW200 dive watch which is good for 100 m.
Casio F91W is water resistant and you could take it in shower, swimming, etc.

**Q: The rubber band broke after 2 years of use. I love this watch and don't want to get a new one. Any tips for a replacement band? Maybe a nylone one?**
A: Aliexpress or ebay you'll find almost exact generic replacements for a couple bucks shipped. Search for words like F91W strap, 18mm watch band. You can also use normal 18mm spring bars instead of the pins that are stock with the F91W.

### ⭐⭐⭐⭐⭐ 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.
