Whats happening guys, hope you are doing well, here's my first ever attempt at a watch mod. Let me know what you think of the end result. Also huge thanks to you guys who continually support the channel.
N-O-D-E did some pretty comprehensive mods for the Casio F91W, they're pretty cool. What I remember is that he added RFID, Changed out the LED to a much brighter one, and reversed the display (black background).
I doed this in a fake f91, and even put another led by just bridgeing with 2 cooper treads worked beutiful ... But wasn't propperly weldee, led falled xd Will buy some more to fix it
I've swapped modules in 2 CA-53 calculator watches to make a green positive display version, I sold the black with negative, takes about 3 minutes. I recently oil filled a MRW200 which while messy isn't actually that difficult, it's an awesome look & is still ticking (bang on every single mark) 2 months later. I've also cleaned the inside of the crystals & dials on a few watches I wasn't happy with though a disaster with a Vostok getting the crown back in recently has tempered my enthusiasm a little, be warned if you're thinking of cleaning a Vostok, the crowns are a bugger to put back in.
nice mod, worth it to try. anyways one can get a new casio or skmei for a small price, but yes that's the biggest problem. thanks for showing this I've looking for someone to actually do it whole day, thanks
Keep a magnet laying around on your desk mate its a huge help when doing watches/fiddly stuff. Honestly can't believe it took me so long to realise how much easier it makes working at a desk with tiny screws. Hope this helps
You didn't mention the most interesting thing... You have a positive LCD display that lights up only the numbers as if it were a negative display. Outstanding look. I've seen Casios and Timexes do this on very rare occasion. It's the best of both worlds and I really wish I understood how to make this happen. It's not as simple as going from a positive to a negative display or vice versa. There's more to it than that. Wish there was a video for that. But nice work on this watch. You have quite the unique F91 now because of that backlight. 👍🏽
I think there's a polarizing filter on the LED that's rotated 90 degrees to the display's polarizing filter so the light only shows up where the digits are.
You are actually a genius lol I’ve been wondering this mod for ages. Just a swap from the SKMEI casing and put inside the F91w’s casing. I thought why has no one thought of this before or made a video and I suppose because it may not fit but you have shown it does, or almost and just as good as it can go. Does the alarm and beep sound still sound ok?
Thanks, I'm not sure about genius but the alarm function works just doesn't make a sound unfortunately. Think I might have broken it during the teardown, but next one I'll know not to do that.
Mine works fine. The only thing i recommend to do is grab pliers and flatten the contact tabs. Otherwise the bends in the metal prematurely contact the board also resulting in stiff buttons. Flatten them and its a dream.
Well it can be done. Before you attempt this, be sure that you checked the accuracy of the skmei module because many skmeis are really bad. They are worst than mechanical watches. The may gain or lose 10seconds per DAY.
HELLO WES , GOOD IDEA FOR COSTUMIZER YOUR CASIO F- 91 . IT ' S GOOD , IT ' S ALL RIGHT . VERY FINE . WELL DONE . I LOVED YOUR NEW DIGITAL WATCH CASIO ! . 😉👍😊👌
They sell these little trays, for people who make necklesses. It's just the flat sheet of plastic, that has a main work area, and dozens of little pockets on the side to hold small parts. The tray has slight walls to catch things if you drop them. My girl friend has one, and she tells me to use it when I change my batteries on my watch. I never listen. I was changing the batteries on watch I had since I was eleven, and dropped two screws. No my watch doesn't work. They are very cheap. I wish I listened.
Thanks mate and why Nutella? But it sounds like you've dabbled a little. Hopefully if the next one I have planned goes well, I'll be tackling a more in-depth mod
@@WesWatchRoom I have been searching up and down. Please if you have a moment and can find the link I would be very grateful. Some of my Casio models can not accommodate the thickness of s rubber strap. This one seems perfect? Do you own a Casio a168? I tried to get generic silicone strap and learned that although it's a perfect 18mm lug width, it would not accept the rubber.
Recently my f91w's straps finaly gave out after 3 years of daily use. I replaced it with the A158W basically the stailes steel version and I thi k I have a use for the old watch now
I once tried the hydro mod with a Casio MRW200 absolutely the messiest thing I have ever done haha, the result was pretty cool but it took forever to clean the watch afterwards 😂
@@WesWatchRoom no i didn't that was pre RUclips channel. Would I do it again but film it this time? NO absolutely not! 🤣 far too messy, I got in quite a bit of hot water with my wife because of the state of the kitchen table (& the cat) it was right up there with the time that I "set fire" to a watch on the same table to get some "cool footage" for an IG post 🤣🤣🤣🤣
So skmei module in a Casio watch, I'm going to buy the skmei watch instead then😅 might try rubbing off the Casio lettering and words to make it stealthy for the next mod?
Only Mod I'm considering is the Oil in the Casio MRW 200 H. Looks pretty simple. Ever Tried it ? It's one of my most affordable Watches but the one I Love most and usually have it on when I'm relaxing at Home. Peace Out.
@@WesWatchRoom There's a plety of RUclips videos explaining how to solder, and I'm sure you can get a destroyed electronic something to practice on it. Remember just one thing - There's never enough flux ;) (Until it's rosin, it's a lot more messy)
"Spoilers"? Kinda want to know what I'm watching. Like what is the "biggest problem"? Not sitting through half or more of the vid to figure out what and why you are doing what you're doing.... I mean, the backlight isn't bad enough for all the trouble, I can still read it in the dark, it's no indiglo but it is fine. Cool mod and all but jeez man. Just explain it up front

Thats all I wanted. A F91 with a proper backlight.....
Absolutely and same with everyone else too
Buy a Casio a700 👍
That would basically be a F-105
A F-91 with good light and even 50 meters WR? That's called B-640W (or B-650W if you prefer it bigger, more masculine and not so "unisex")
All I wanted was for the two watches to be synced up...
i did this with a blacked out case mod from a casio i bought before.. it looks so freaking cool now with the new backlight.. easiest mod ever
I bet that looks awesome and you're right, such an easy upgrade to do. Appreciate you watching

Very nice, sounds like you've done some cool stuff. It's definitely quite addictive watch modding.
I agree with you on that, the crowns are a pain to get back in
Oh, wow. U upgraded the SKMEI
nice mod, worth it to try. anyways one can get a new casio or skmei for a small price, but yes that's the biggest problem. thanks for showing this I've looking for someone to actually do it whole day, thanks
Thank you, glad you found it helpful. Have a good one.
Congrats on your first modding hopefully more to come 🤞
Thanks man and yeah I have one to repair and then when my backlog is clear, I'll be buying parts for my first build
@@WesWatchRoom is that gonna be a future video and you're welcome
@@watchsixto yup it certainly will. Just got a fair few to get through first
@@WesWatchRoom definitely can't wait to see what your build would look like
@@watchsixto thanks and hopefully it'll be before Christmas
Nice job! I've tried fiddling around with my Casios but quickly realized I don't have the patience nor the dexterity to complete a mod. 😆 Great video.
Yeah it was actually easier than I thought once I knew what to do. Thanks very much
Easier to buy f-105 :D
But the idea is great! Cool!
That's very true, but no fun.
Some people may find it stupid but if it's for your own DIY project it's fun :)
Definitely agree, modding is fun and a great way to upgrade the watch too
A F91 with a goodbacklight is a f105, nice mod, like a reverse of f105 when you use the backlight.
Keep a magnet laying around on your desk mate its a huge help when doing watches/fiddly stuff. Honestly can't believe it took me so long to realise how much easier it makes working at a desk with tiny screws. Hope this helps
Very cool Wes! You had me gasping whole time hoping you didn't break anything 😅😅😅😅Nice video 💯💯💯💯💯💯💯💯💯
Thanks mate and everything is working absolutely fine.
that backlight is even better than stock casios
Can’t believe I missed this video
All good mate, appreciate you watching.

But nice work on this watch. You have quite the unique F91 now because of that backlight. 👍🏽
Yeah that is a good point and its the module from a skmei f91w homage. It does basically the same as an F91w just with a better backlight. And thanks
I think there's a polarizing filter on the LED that's rotated 90 degrees to the display's polarizing filter so the light only shows up where the digits are.

@@AllSnipe thanks for the tip. I didn't think to do that as it was my first attempt.
Nice job man! Not perfect but a success for sure!
Cheers mate and for a first attempt it went well but I'm sure it could be done better
im looking at doing this. bought the skmei 1412 watch to replace the lcd for the much better light
The module from the A-700 is a drop-in fit for the F-91 case.
Well it can be done. Before you attempt this, be sure that you checked the accuracy of the skmei module because many skmeis are really bad. They are worst than mechanical watches. The may gain or lose 10seconds per DAY.
That didn't really matter, I just wanted the better illumination, its only my beater watch so accuracy wasn't a concern.
Just get the F105-W 😄
Very nicely done 👍👍
Thanks mate, I really like how it turned out
Swapped out the module from a Skmei clone to an f91, for tbe improved backlight, unfortunately the Skmei has poor accuracy.
Looks cool 👌
Thanks very much mate.
How’s the accuracy compared to casio module
It's good but not as good as the original
HELLO WES , GOOD IDEA FOR COSTUMIZER YOUR CASIO F- 91 .
IT ' S GOOD , IT ' S ALL RIGHT . VERY FINE . WELL DONE . I LOVED YOUR NEW DIGITAL WATCH CASIO ! . 😉👍😊👌
Thank you
The silicone strap looks nice, what size is it? I can't find the aliexpress link in the desc
Bro i Loved tour mod, where can I get that beautiful strap you got on that f1w?
It's from AliExpress. I just searched for an 18mm silicone strap and this appeared
I wonder if the LCD is swappable from both, I have ordered different variations to try.
Cool, you'll have to let me know if it works.

Thanks of the tip I actually have a little tray now but luckily haven't misplaced anything major as of yet.
Now I know why I don't do this thick fingers and would break it as soon as I started
Yeah, it can get a bit tricky with the small screws. Thanks
Where do you get all the stuff to mod it???
I'm going to call this the Nutella mod, I tried a watch build and yeah ordering a new movement and dial, so there you have it lol
Thanks mate and why Nutella? But it sounds like you've dabbled a little. Hopefully if the next one I have planned goes well, I'll be tackling a more in-depth mod
@@WesWatchRoom becuase you used the nutella lid lol great use of recycling and helping the environment
@@thebaldwatchcollector ahh, yeah that's all I could find 🤣 and I'm doing my bit.
Hey what is silicone strap?
Its just a bog standard one from aliexpress

Well done [you maniac]
Hahaha, thanks man. 👊
Made that very complicated 😅 I was wondering why you were taking module apart in first place😁
I know, I thought I could swap them over like that, but I figured it out in the end.

That sounds like a really good idea.
Only Mod I'm considering is the Oil in the Casio MRW 200 H.
Looks pretty simple.
Ever Tried it ?
It's one of my most affordable Watches but the one I Love most and usually have it on when I'm relaxing at Home.
Peace Out.
I haven't tried it personally but I could do in the future. Thanks for the suggestion.
Save the hassle and just buy the W86!😁
You really could, I didn't know the w86 existed when I made this, but that would be a good call. Thanks
he sounds like the n-o-d-e guy
Not sure who that is, but I'll have to look now 😄
Video molto interessante, forse però hai dimenticato di riposizionare la guarnizione sotto il coperchio per renderlo impermeabile.
Why not just keep Skmei 1412 instead of all that work? 🤔
0:01 sec what's up ni**# people😮
Now you have a fake f91w😂
Does this work for the a158
Possibly as I think the module is the same as the f91w, so as long as the case is the same size, should be fine
The EL backlight uses battery up to fast, Casio dropped it for that reason alone
Modding a ten quid watch can only increase its overall value by 15000% with any decent strap 😂
I dont know why they don't just re-release the F91W with a decent night light. Maybe call it the F92W.
Just solder an 1206 SMD in the place of the orginal one 😑
If I knew how to solder that would be great.
@@WesWatchRoom There's a plety of RUclips videos explaining how to solder, and I'm sure you can get a destroyed electronic something to practice on it. Remember just one thing - There's never enough flux ;) (Until it's rosin, it's a lot more messy)

@@kshysztof9649 very true, it'll be a great skill to have.
What is the problem that you fixed with this mod? Thats not clear at all😅
Just use the white thing and replace it with the original
Just get a Skmei !!!!
ew no
Its like a f105
Honestly never heard of a 105 but I'll look at one. Thanks 👍
Great watches but yeah the light is absolutely trash and it's not gonna be illuminating anything at all.
Thing is, those SKMEI's lose too much time.
Fake, that was another company watch😮💨😮💨😮💨
😂😂😂why don't you just buy an F105W?
