Cheap, Functional, Durable, and Now Comes in a Whole Bunch of Colours
Even before retro became fashionable, I've sworn by this watch. It's functional appearance certainly has its charm, but what really makes the Casio F-91W-1YER great is its simplicity and longevity. It's a watch that does watch things - it very clearly displays the time in either 12 or 24 hour format with a little green light for telling the time in the dark, it keeps track of the day and date, it has an alarm and the option to have it chime on the hour, and it has a stopwatch with lap function. It does everything you want a watch to do, for a very modest price - I've seen plenty of watches cost far more but do far less. That's not all. It goes on forever. Well, not literally, though it certainly feels like it. I've owned mine for somewhere between five and ten years now and I've not had to replace the battery once. Also, despite working in a laboratory with a million-and-one different ways to melt plastic, corrode metal, kill circuits, etc., not to mention regular commandeering by a toddler over the past year, it still looks almost as good as new. I've friends who work on building sites and in the armed forces who can attest to the durability of this watch too. It has, as far as I'm aware, only one Achilles heel, and that's the strap. This tends to wear out before the actual timepiece does and once it's gone, you might as well just buy a new one. That said, it's not like they wear out quickly (mine's still as strong as ever), nor is it as if they cost a bomb to replace. Other minor (and I stress the word "minor") issues include having to reset the date on a leap year (oh no, I have to spend a minute setting the date on my watch every four years - whatever will I do?!) and the green light not being powerful enough for some folks to see the display properly (should've gone to Specsavers...). Anyway, to end on an up-note, here's my conclusion - buy this watch. It's cheap, functional, durable, and now comes in a whole bunch of colours. What's not to love?

Good product. Be realistic about it's image and you'll be fine..
This is an excellent product in this day and age. It's exactly the same as it was thirty or so years ago. It hasn't changed one bit. Has nice charm and retro appeal. Has good water resistance and feels like it will last years and years. It does its job and the alarm is louder than every other watch I've ever had. It actually wakes me up. But be realistic. You won't be wearing this to too many social events. It can come across as quite nerdy, especially when compared to more modern big watches. One person even thought it came out of a vending machine at a kids fairground. You know the one where you put a coin in and an egg comes out with a toy watch in it. But I like it. It's small size actually works in it's favour for the job it does and makes it more practical than any other watch I've had. I don't notice it on the wrist and I can sleep in it. True, it has got an old school LED but I can make out the time in the middle of the night. It really is a wear and forget watch. It's nice not to have to worry about changing the date at the end of the month and the stop watch is being used every day to time pizzas in the oven. So all in all it's a yes from me. You're wife will hate it with a passion just as mine does and so might some of your friends. But for the price it's amazing. Casio quality just as it was in the 80's

A Classic
Probably even more practical today than it was in 1989. Easy to set up, 10 year battery, quality Casio and does for work. Great value.

Basic, functional and cheap but strap breaks after just a few years.
Basic, functional and cheap but strap breaks after a few years, so not very environmentally friendly as it's often cheaper to buy a new watch than get a new strap fitted. Yes, I know you can buy replacement straps but they're very fiddly to install and not that much cheaper than a new watch!

Classic cheap knockabout watch
To start with, I see comments regarding the fact that this watch is not waterproof. Well, it is rated as water resistant, which means up to 30 metres of static pressure. In the watch world this means it is splash proof only so don't be surprised if you swim in it and it dies. It's ok in the rain. That would not be a fault of the design! The design is classic Casio circa 1989 with a crappy backlight, stopwatch, once only daily alarm, hourly chime, month, day, date, hours, minutes, seconds. Casio have been making these for over 30 years and produce around 3 million a year. This is probably the best selling wristwatch in history. It's small, the strap is small, however it fits my 7. 25 inch wrist ok. The strap will wear out before the battery does if you wear it all the time, but replacement straps can be purchased for under a fiver and changed in 2 minutes by pushing out the pins in the direction of the arrow with a paper clip held with small pliers. Most people just buy another f91w. It's under a tenner, it is accurate to 30 seconds a month, and you can throw it in the air and let it land and it will still be ok. This is my 3rd. I don't know what happened to the first one. The second one is still going on the same battery after about 6 years and I bought another while they are still under a tenner. You get what you pay for and for under a tenner these are great value knockabout watches which you don't need to worry about doing anything in, just don't criticise it if it dies after swimming. It isn't designed for that.

Tout est dans le titre. Cette montre d'entrée de gamme fait tout ce qu'on lui demande et en plus se permet d'être robuste, mon ancienne que j'ai gardé plus de 5 ans je l'ai changé car elle était trop griffée. Je pense tout simplement que cette montre est le meilleur rapport qualité prix de la planète ! Foncez !
