There is a Museum of Counterfeit Goods in Bangkok, run by a law firm specializing in copyrights infringement cases. They have a mountain of fake F91 in their display!
This watch is one of the few things in life which u can buy which are original low priced and good quality. My A158 has worked in rain and shine for the last 7 years without a hitch.
Learned some good points here. Another less instant difference I've found is the accuracy. Set both real and fake to correct time over nine months ago. Real one is two minutes slow and fake is over 30 min fast. Other casios set 9 months ago within the minute of each other
A lot of nice information on the video. If you push all three buttons down. Everything on the face should light up and when you push it again, a number should appear. It’s amazing how well the knock off watches are made today my first couple Cassio I bought online were not from an authorized dealer and we’re not real. Learned my lesson real quick.
Okay, I’ve always scratched my head about the obsession around the kislux book totes and their practicality, but this one is adorable!! Congratulations
I can understand faking a Rolex but a Casio?! Fakes didn't exist when I used to sell Casios for a living (from 1979 to 1981). I still wear wear one every day.
You have a watch factory but nobody wants to buy your ding dong watches so you start cranking out Casio models that are already known to sell. I mean if you think about it the PRC counterfeits everything; from fidget spinners to automobiles.
Very interesting! I like to say and think my Casio DW-9900 has a similar secret to Rolex in that at the six o'clock position, there is a very hard to see serial number on my Casio. Similar to the very hard to see crown at the six o'clock position on a Rolex. Thank goodness most G-Shock fakes are horrible quality and can be seen more than a mile away.
The “U” on the crystal is not for counterfeit prevention, it’s the plant that it was manufactured at. All older model casios list the plant on the crystal, for example “Japan a” “Japan u” All the F91-w crystals were made at the U plant.
@@damyr all models made after 2023 do not have the U since they are no longer making the crystals at the separate plant. The “ca510” is done by holding down only the lower right button.
@@bobsmithinson2050 Btw, I've just remembered mine is 5 years old. It's made in China. A black&gold version, bought in a Casio licensed store. 100% original. So, it could be that Chinese versions never had the "u".
@@damyr you’re welcome! Well good point, how is that one? I was thinking of getting it since it’s got a classy touch. Also, the green one looks nice. Does your f91 pass all the other tests in this video? I think the biggest giveaway is the module inside. Fake ones don’t even bother to imitate the original
Great review ..Ive both genuine and fake ..Also another big give away is the colour of the blue outlining around the screen fakes tend to be lighter blue n genuine darker blue..But the fake ive got has a seriously loud alarm beep...dreadful lcd though like uve stated.. Also the back plate on fakes is a massive give away they cannot master the brushing as casio do...Plus fakes tend to say made in japan..Theyre not made there anymore as far as im aware hence no U on the inner casing...Its mind boggling how theyll fake nowadays a £12+ casio legend...Why casio didnt make this watch into a 38mm is beyond me theyd go tenfold on sales as they are a seriously small LEGEND piece that we love n hate all in one.. Must have for die hard casio vintage collectors...😁
* The light on the genuine F91 is rubbish, it only illuminates half the screen, the fakes have better lights. * The back of the fakes say the unit was made in Japan, only very early F91's were made there, but they are now made in China and Indonesia.
This has always been a controversial point of the module 593 (F91-w and many others). The light was made this way on purpose to fulfill the battery life expectancy. The original F91 from 1989 was advertised as having a 7 year battery life. To meet this criteria, the light diode couldn’t exceed a certain threshold or it would drain the battery too much in the long run. Keep in mind that every time the stopwatch is reset, the light comes on. Many other models only boasted a 5 year advertised battery life. Anyways, I agree the light is terrible, but it was done for this purpose
@@bobsmithinson2050 I never knew there was a strategic reason for the poor light, but knowing that CASIO put that amount of thought into what has always been a cheap watch just makes the F91 even more epic.
@@007sarabond exactly my thoughts. I agree. Another cool aspect of the dim light is military use. If you’re out in a dark field across enemy lines, you wouldn’t want and “illuminator” style watch giving away your location.
My "Secret Santa" present was a pair of Casio F-91s. I now know that one is genuine and one is a fake! I might hold a competition at work to see if anyone can tell which is which...
I bought a fake Casio watch. It was a ripoff of one of their affordable models, and it was really inexpensive, and junk right out of the box. After a few months the buttons didn't even work anymore.
I agree with everything you said, but....I don't understand how a making of the fake F91, which is cheaper than a meal at McDonalds can be financially ok....I really don't understand....my advice for anyone is - buy a watch from the reputable seller....a possibility of buying a fake is small, but a possibility of piece of mind is really big....it's not going to be a cheapest possible option but it will be hassle-free. I got absolutely nothing against the fake watch sellers even though I don't care about their reasons, but I got a lot against the people which are buying those watches....those things are just a bait for the fish. By the way, that fake is really produced good, no matter what..I mean, can really anyone complaint about the cheap looking circuitry if the price tag is ....symbolic I must say? Don't forget.....without a demand a supply wouldn't exist, that's for sure.
Where I am, a genuine costs $60 aud to buy. I got a fake from eBay for $17. - My fake does the Casio screen and the jumbled symbols trick. - The screws are exactly how you described for the genuine where one of the lines goes all the way. - The back is brushed stainless. - The screen is clear from all angles. You can read the time at all angles. - The ‘U’ is in fact tiny and almost non visible as on the genuine watches The reason I know it’s fake is the packaging it came in, my watch says made in Malaysia, all f91w are made in china and will say so. I also know my one is a fake because the bell symbol is the alarm and the stripes are the hourly chime. Should be the other way around. I also know my one is fake because I bought it off eBay 😂 I don’t care though, it is accurate and keeps time within a millisecond when comparing to my phone and only cost me $17 and not $60. I wanted a new watch to use daily and beat the crap out of and not care and this one does the job well.
To see the Casio text, you just have to press and hold the right button. There's no need to hold both the left and right buttons. The fake is doing it wrong. 😅
Dunno what to say. My GShock square case back started exhibiting rust after like a few times wearing and one sweaty run outside. It seems legit but the quality of the stainless steel is yikes Bought it from First Class Watches UK fwiw.
people fake anything. it maybe cheap but if the f91 is the best selling watch in the world, and the casio name is the most recognisable brand in the world, so if you're gonna fake anything, why not do it with that? it has great stats
Dude, you want to show us fakes vs real but you don't even know how to display casio. You don't keep pressed both buttons, you must only keep pressed the right bottom button.
I never would have expected this watch to be faked. Amazing. Very informative video.
There is a Museum of Counterfeit Goods in Bangkok, run by a law firm specializing in copyrights infringement cases. They have a mountain of fake F91 in their display!
I heard what could be a rumor, that the U was being removed from the current F-91W production.
this is true
yes, from 2023
7:08 Hold only the right button it will show you Casio.
Just did that got a silver one at Walmart for 21 dollars

It's all about the profit margin and volume of sales.
You understand when you sell thousand and thousand

Believe it or not there were fakes of the early 80’s models. They were very obvious too, as the graphics on the crystal looked very wonky
The light is another way to spot a fake. I had one that flashed different colours.
recently manufactured F-91W no longer have the small U at the bottom anymore. just for anyone's info.
All valid points, someone I know just has just to look for another screen name now :)
The words on the watches is different too, look at casio and the WR, the colours.

they copy the f91, because they know the name casio will out sell any other name.
Good info.
Glad it was helpful!
Excellent video. Thanks for the tips 👍:)
No problem 👍
@@Oldcasiocollector ;)
Also I notice the four grooves are different in size.
true
I also think the blue surround is different. One the fake is slightly not vibrant.
yes
The printing on the face is perfect on the real one, poorly done on the fakes.
thank you for your knowledge!
My pleasure!
Don't push the 'mode' button with the '24hr' button if you want to see the 'casio' icon on the real one. That is where you mistaken
I’ve two ‘first copy’ A171s. One needs to have really trained eyes to identify that these are fakes.
interesting

Why would anyone buy a fake of this, they’re like £12

thanks. i had brain fog
I just bought one from Amazon and it doesn't have the 'U'. Is it a fake?
You got finessed
Not necessarily. The U is no longer there.
I bought one from AUS Amazon a couple of months ago and it has no U at the bottom.
Interesting what does the LCD do?
The new f91w models do not have the small U anymore
What quality difference is there between them?
to be honest to a normal person..... nothing.
@@Oldcasiocollector lol. okay, I will take your word for it. What little differences are there for abnormal watch enthuisists?
Apparently the readability, which is a big deal if you ask me. If it's hard to tell the time on watch then that's a bad watch.
Dunno what to say. My GShock square case back started exhibiting rust after like a few times wearing and one sweaty run outside. It seems legit but the quality of the stainless steel is yikes
Bought it from First Class Watches UK fwiw.
the screws are stainless steel, impossible for them to rust. real casios are anyway
Oh heck.... Time to go to china town
I just bought one and it hasn’t got the u on it I got it from Argos 😢
dont cry, things will be ok.
🤣thanks mate I just realised the new ones haven’t got it
Nice video. Please learn to edit.
The original is so cheap....whats the point of a fake. Just go to a shop.
