Casio Classic F91W Series Quartz Watch | Water Resistant |1/100 Second Stopwatch | Daily Alarm | Hourly Time Signal |Auto Calendar |SS Caseback |12/24-Hour Format

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.

This is the second Casio F91W-1 watch my husband has bought in modern times. The last one has lasted 2.5 years and the battery is still going. Sadly the strap had split and there is no way to replace them. He loves the retro design and how neat the watch is.It arrived packed in a clear box. The face is a neat 3cm x 4cm. The strap is 7.5cm from buckle to attachment.The biggest negative is the night light is not that strong.Otherwise the functions work well and it is waterproof.The functions include date, time, stopwatch and alarm.We would highly recommend this watch especially for under £7.50. It suits a make or female.Bargain.

I have used this watch for several months now, and I can confidently say that this is a good watch for the price! The water resistance is great, it holds up to taking baths with it, and swimming with it. The timer is accurate, however i have found that the seconds go late around 1 second every two days, although i do not mind this. Its easy to read in the day time, but the light is not very good at night. It does still work though. Overall, it is a decent watch for the price.

It is a classic watch for a reason. It is really easy to set up and change settings on it unlike other digital watches where I seem to need the instructions every time I wish to change anything no matter how simple, as a woman I was slightly concerned that it would not tighten enough on my wrists but you can do it very tightly it practically has notches the whole way round. I use this watch for work and at the price I know I don't need to worry about losing it as it won't cost a fortune to replace. However, it is very durable and has lasted a season of being battered, thrown around, knocked and general wear and tear and it is still going on. If you want a trooper of a watch at a good price that will do the job of a watch this is what you need.

I bought this renowned watch for its iconic status. Many reviews have already been done on the quality and functionality of the watch, so I'm instead going to add the following interesting facts:1. Most folk say this watch was released in 1991, but in fact it was released in Japan in 1989. This makes it the longest manufactured digital-watch in history.2. Casio state that these watches continue to sell around 3 million of these watches worldwide EVERY SINGLE YEAR making it the best selling digital-watch in history.3. The watch was worn by Barack Obama AND Osama Bin Laden....more or less simultaneously!4. Due to its construction and availability, the Casio f91w was adopted by terrorists for use as timers in Improvised Explosive Devices. The CIA considered possession of the watch as an identifier for their 'terrorist watch list'. At one point, it is alleged that over 30% of inmates at Guantanamo Bay had been found in possession of either a F-91w or a variation carrying the same module.5. With a good battery and the watch kept at body-temperature, accuracy over time is said to be more accurate than mechanical/analogue designs....including Rolex!6. This model has been displayed in the London School of Art, due to its iconic design.7. Purists refer to this watch as the 'happy meal watch' due to the fact that, wherever you are in the world, the watch generally retails at the same price as a Macdonald's meal.Some people are worried about the 'Water Resist' standard? Well the following is the official standard (ISO 2281) which the watch is able to exceed:Resistance when immersed in water at a depth of 10 cm.Immersion of the watch in 10 cm of water for 1 hour.Immersion of the watch in 10 cm of water with a force of 5 N perpendicular to the pusher buttons for 10 minutes.The watch shall be placed on a heated plate at a temperature between 40 °C and 45 °C until the watch has reached the temperature of the heated plate (in practice, a heating time of 10 minutes to 20 minutes, depending on the type of watch, will be sufficient). A drop of water, at a temperature between 18 °C and 25 °C shall be placed on the glass of the watch. After about 1 minute, the glass shall be wiped with a dry rag. Any watch which has condensation on the interior surface of the glass shall be eliminated.Immersion of the watch in 10 cm of water at the following temperatures for 5 minutes each, 40 °C, 20 °C and 40 °C again, with the transition between temperatures not to exceed 1 minute. No evidence of water intrusion or condensation is allowed.Immersion of the watch in a suitable pressure vessel and subjecting it within 1 minute to the rated pressure for 10 minutes, or to 2 bar in case where no additional indication is given. Then the overpressure is reduced to the ambient pressure within 1 minute. No evidence of water intrusion or condensation is allowed.Exposing the watch to an overpressure of 2 bar. The watch shall show no air-flow exceeding 50 μg/min.(No magnetic or shock resistance properties are required.No negative pressure test is required.No strap attachment test is required.No corrosion test is required)So there you have it: The Casio f91w. Probably the most astute £10 purchase you'll ever make!

I Love this watch, I know its not expensive, but its practical, it does everything I want from a watch, time, date, a note plays at the hour every hour. The main reason I bought this watch is because the display is easy to read and shows the time and date constantly. The only drawback is that I am a man, and I think the strap is meant for a woman, its just too short (or may be I'm just overweight?)

Arrived in immaculate condition and with Amazon prime delivery time was amazing of course. Fits great on my wrist (not sure of the measurement) and I think it looks really good and retro. Does the job for a cheap price and is highly reliable with all the necessary features, a smart watch of yesteryear.Little secret about the watch for anyone with one, holding down the single button on the right for 5 seconds displays 'Casio' on the screen, quite funny I thought.

From my headline you can safely say I love this watch. It just looks so good, feels so good and feels so much a part of me from the moment I put it on. It has to be said it is small but as the saying goes "good goods come in small parcels. Other reviews have listed the workings of the watch so I won't add to it. However it will be hard to beat the price and style of this watch. I bought the watch on Amazon from "7dayshop.com " who offered a wonderful service with the watch arriving a day early securely packaged and well presented. Brilliant
