Warning , total watch noob here . I just ordered a Casio f91w, I had one when I was 13 or 14 . I'm wanting to get back into wearing a watch but didn't want to spend too much if I find I'm not wearing it. Was watching a video and they were talking about knock off f91w watches . Question is how can I get a Japanese made model ? I'm seeing them made all over Japan , China , Malaysia , Thailand ?

Get an authentic one, not a fake. Yes, they fake these.

You can jam a thin AliExpress NATO strap in there if you remove and reseat the factory bars.

While your at it you should buy an M5610 and a Duro.

@ctfish15      Tell me a bit about M5610 and the duro .
6/23/2025 9:15:16 PM EDT
[#3]
So the duro is a dive watch. M5610 looking like a much higher version of the budget line f91w I think 🤔 ?

Buy from a reputable seller on eBay that shows the actual product for sale. If you're wanting a Japanese made one, check the pictures or ask for country of origin.

The 5000 series are iterations of the original G-Shock design. I like and recommend the GW-M5610U-1 because of the solar charging and atomic time keeping.

@WTFShane  solar charging sounds awesome actually.

@ctfish  looking sweet.  Is that a silver f91w ?
6/24/2025 12:09:08 PM EDT

It's the white clear. https://www.casio.com/us/watches/casio/product.F-91WS-7/

There are whole fanbases for the Casio watches. (And others etc)

The F91W is cool. Small. Historical.

The m5610 is atomic and solar, and a mm or so smaller than the typical square 5600.  

The duro is the cheapest reputable 200m dive quartz watch on earth.

The casioak, eh, have not been warm to it recently but it also has a fanbase.

@ctfish15  thank you for the information.  I'm intrigued by a inverted screen color f91w I saw .

@Moon-Watcher  I really like the reverse color format ,  I have it set up on my phone. I figured it'd be fitting to have it on the watch too.

One other thing to keep in mind is that negative LCDs vary in their readability.  Try to see one in person before you spend too much money.  Reviews tend to be done in optimum lighting so they show up on video.  

The next step up in Casios are the ones with the MIPS displays.  They are negative but use different, high contrast displays.  They are a more expensive option.  Cruise eBay and you'll see what I mean.

I just got my first Casio f91w like a week ago and it was before I knew how to look for a knockoff and that's what I got. And I ordered another one that I thought was legit and it just came today and it is a legitimate f91w - 1 .

I haven't looked into this. How do you know it's a fake vs the legit one?

Did you know about the secret Casio message on the hugely popular F-91W digital watch? ????#casio

ETA: Well, they're using the same method.  If the message isn't present, it's bullshit firmware.

@WTFShane   A few I've picked up are tilt the watch back and forth and the numbers go all 8888 on a fake . The direction of the brushed stainless steel on the back is different .My fake doesn't say Casio on the front. Holding two buttons on a setting screen will show the "CASIo " Easter egg . Packaging , my knock off came in a plain plastic bag with no paperwork and my legit one came in a blue and white Casio display box with paperwork.

As I mentioned in my original reply, did you buy it from a reputable source? Was it advertised and sold as a legit F91W? How much did you pay for it?

I've purchased 3 off of Amazon in the past few years, all legit

I'd like to see one of these disassembled and compared to a genuine Casio.  It sounds like it's possible the factory making the legit models kept the machines running after hours to make some extra units, sans the proper branding, to make some side money.  It wouldn't be the first instance of such shenanigans.

@WTFShane  it was on eBay and said "authentic" on the ad and it was listed at $6.55

Everything on eBay is counterfeit, and half of Amazon is counterfeit, the other half is used.

Here's a much more definitive comparison between a real and a fake F91W.  The Easter egg has been replicated in the fakes, so that's no longer a useful test.  I find it amazing that the Chinese would bother to fake such cheap products, but they probably make decent money doing it in bulk.

@Moon-Watcher  .thx for the vid . I agree it's crazy the amount of work they go to to make a fake when they could just make their own watch that would probably sell well enough because it would be a new watch on the market .

still the best basic watch

OP

You want the other other NASA watch.  Casio MRW200




I had been looking at the marathon navigator and clones ... When all of a sudden, it was like I heard a voice ... And of course Casio had the answer all along. All this time, it was available for $20

It's lightweight, the bezel turns, and it's 100m.
