How To Install Negative Display To Your Casio Watch

Hi,
I made this step by step tutorial to help people who bought negative displays and now struggle to fit them in.
This display modification will fit F91W, F84W, W59, W86, A158, A159, A163, A168 and more

Managed to swap my original LCD screen on my A168W. The negative display looks great with the green illuminator light on. Thanks buddy

[@LestestsdeCarlo]

Cool ! I think it will match well with my grey F91 w

[@iMolleggiati]

Just bought one! Waiting the shipping! Greetings from Rimini, Italy. Love your work. Keep it up!

[@Techsas]

Thanks for watching!

[@cherepaha3]

Rimini full of so called refugees

[@iMolleggiati]

@@cherepaha3 we don't have refugees lol...stop watching the tv man 😂

[@chanbeompark2402]

Just bought the display off of your etsy store, gunna try and replace it, thanks!

[@gdwiggins]

I love the Dbrand style!

[@weedsmokinator420]

It took me by surprise.

[@andrewshadowy2025]

Will this tutorial also work same way for the coloured displays?

[@DanielForMetal]

May I ask you where you buy that kind of inverted display?

[@prioritisingprofit]

i have a casio a700. It is my favourite watch but I wish it had the toquise led. it has a orange one. do you know how i can change it , or can you possibly do it if i pay andpost it to you please.

[@sirBumpyCase]

i love your voice!

[@JabbuGuy]

i love that surprise at the end

[@Djrolian]

I was thinking on ordering the negativa display from your etsy store but im not sure if the dismantling process makes the watch less water resistant. what do you think ?

[@Techsas]

I never had problems with my watches that I dismantled in the past, mostly because I follow Casio recommendations and don't go swimming with the watch. Although, living in England gives me a great opportunity to test the watch by unintentionally soaking it and myself in the rain 5 times a week. Make sure you place the rubber gasket properly and don't overtighten screws and you'll be good.

[@piipis]

does it light up well?

[@sendalcepit6039]

Any risk change inverted lcd,sir?

[@TheHungaryPSB]

Very good job

[@lndianScammer]

When will the product be back in stock?

[@eggycat]

Wouldn’t it be possible to flip the polariser and get the same result? I remember doing this by accident to my gameboy a few years ago but maybe the original polariser would have to be removed first…

[@jaymo2024]

I inverted my Casio F91W lcd color without changing the lcd by accident so I believe I probably moved the polarizer angle

[@gilbertpohantube]

Already got this dark cool version of F 91w. Planing to do the same with ca 53w, any idea/option for getting the negative LCD. Thx

[@Techsas]

You'll have to do it yourself

[@gilbertpohantube]

@@Techsas ouw my bad, i mean where to get it, if i want to buy it wht is exactly the name for tht material?

[@obj5449]

dude i fond one one his etsy and they are still there as of sep 20 2020 go get one if ya need. also really good video mate!

[@Techsas]

That is probably mine etsy shop

[@sondification]

Bought one off your Etsy the other day, after binging your videos! Cheers, can't wait - you're a life saver.

[@Techsas]

Thanks!

[@BLKSG6]

Is there no way to remove the polarizing filter from the LCD and finding one that is rotated 90 degrees?

[@alexkastano96]

it takes more time and straight hands))

[@HectoriniAvalosgallardo]

Eres excelente 👍

[@snozzybosch7503]

Could I do the reverse of this with my Casio square that has a negative display……? Also I would like to replace the buttons to the gold ones and the springs and screws too……..?

[@martin_the_grasshopper1991]

@techsas do you know if this will fit the 3479 module in the A1000? Also do you know if any of the electroluminescent modules fit the A1000?

[@Techsas]

Hi, no this does not work with A1000

[@Techsas]

A1000 is mapped differently

[@PixelZan]

The A700 module fits the A1000. I just bought one to replace the negative display on my A1000.

[@and_rew9768]

Well done

[@gilbertpohantube]

Just like mine, wohoooo

[@tritran4437]

Hey there, when will you resume selling this?

Guys i did this mod but it's hard to read the numbers in low light Any ideas?

[@NeillRobinson]

Will more be coming to Etsy ?

[@PHOBlIA]

Can short ac be done with regular paperclips?

[@Techsas]

Yes

[@dtancler]

hello! I've tryied to buy one of those displays in you shop in Etsy and the purchase was cancelled... Etsy didn't let me contact you either! :( sorry to bother here... do you ship worldwide by Etsy or there is another way/marketplace to get one? thanks in advance!

[@Techsas]

Not sure what happened. Where do you live?

[@dtancler]

@@Techsas I'm from Brazil!

[@iliasmastrogiorgos5508]

I'm very interested into buying a couple of these from your store. Are the digits same size as the original or the bigger ones that usually fake Casio's have? Does it also have the alarm and hour signal visible? Dont want to ruin my Precious

[@Techsas]

The size is the same and it has all the icons like original.

[@v1d300]

So the cost of negative display is likely 70% the cost of F91W?

[@Techsas]

It's purely for cosmetic purpose and you don't have to buy it.

[@v1d300]

@@Techsas hey I am all up for mods, mods occasionally do surpass the cost of the watch anyway. I understand that. Thats the point of mods, make them personal and well worth more than the MRP.

[@cekpi7]

It's possible to do this on your own, but if you damage your LCD, you will have to buy new F91W and that's 100% the cost of F91W :)

[@azeael8429]

Hello, I am not sure how the reset display step work? Could you give me any pointer? Does it require special tool to push in?

[@Techsas]

You just have to short it with a metal object, paper clip for example.

[@azeael8429]

@@Techsas i managed to make it work somehow, I still don't understand. I pushed in the same hole you showed but it doesn't work, so I tried pushing in every hole and that somehow fixed the problem after waiting a bit

[@escuadrojoyce]

Can you mod the AW48H please? Ur a genius!

[@subhrojyotidas7614]

I have golden colour casio f91 w..

[@Alessio5005]

Did you manage to produce them in some way or are you making them handmade? Plus, how's the readability compared to the "normal" handmade ones?

[@Techsas]

I got them manufactured in Hong Kong. Readability is better than DIY and even original Casio ones.

[@Alessio5005]

@@Techsas Cool! I think I'll buy it soon

[@watchncarry9593]

Nice tutorial. But "all this other stuff if you're a... "? What do you mean by that?

[@Techsas]

It can be done without any of that stuff it just makes it easier

[@Wagner669]

Negative displays look cool, until you need to check the time.... Where did you get the negative display? Did you have it laying around from a previous project or you purchased it as a part? What's with the voice-over? It's kinda funny and kinda strange at the same time The butterfingers joke, at the end of the process... LMAO!!! Great video :)

[@Techsas]

You can buy negative display on my Etsy now. It's a little better then self made ones in terms of reading it.

[@v1d300]

I think the voiceover and the tone is like a parody to dbrand skin installation videos. They have the same voiceover and sarcasm.

[@Wagner669]

@@v1d300 I see! Thanx for the info!

[@Wagner669]

@@Techsas to be honest, I'm mostly interested in converting negative displays into normal, that you can actually see the time :)
