Hi Techsas, what is the purpose of constantly shaking the case with the tweezers @ 3:10 (around-about)? Is it just to get the LCD component into the case, or is the extra shaking also to get rid of bubbles? Thank you. Also did you have any tips to avoid bubbles in the front of the LCD? Thanks
Hey, the shaking is to avoid bubbles. If there was any bubbles under the module then shaking most likely helped to get them out. Other than that jus try and do everything slowly rather than dropping it in the oil and you should be good.
I heard that companies like ressence will add everything to the casing and then put the whole bath into a giant freezer so the oil is as dense as possible in the casing once it's sealed.
just done this yesterday with my f91w. crappy display doesnt help with viewing angles as much as it does with an analog watch but still, makes it more water and pressure resistant
yeah, mineral oil isn't great on plastics, see the mineral oil submerged PC trend fron like 2012-2016 I would love to see a follow-up on this watch though, if you still have it
No worries mate, for sure it will work. Only one thing that you need to consider, Casio AQ 800 is a solar powered watch. The oil will reduce the solar panel sensitivity of AQ-800.
Just did some oil modding 2 days ago... didn't turn out so great, I really need to use a syringe or something to get more air out. I really wanted it to work on my white face timex Waterbury indiglo. I think it would look killer if I could pull it off.
@@NK-ng2vg It did, yes, but I was unable to test it long term. I had a friend that wanted to buy it, so I dried it out for him and he has it now. It still works.
@@Techsas I own personally one and its fantastic. You can make a tactical model. Putting a dark nato, paint the watch and also invert the color screen..
Lots of reasons not to. Cooking oils can be more reactive thus cause corrosion or they can be conductive mineral oil is particularly reactive with abs and pvc both of which this watch contains quite a bit of it will make it brittle and break down the plastics.
Not only that, but have you ever smelled cooking oil after it turns? I don't how to describe it, but it is one of the foul stenches around. I also don't know how long it takes, but it's definitely inside the two year mark.
@@Techsas Well I suppose if the clearance between the buttons and the watch body is very small, say: 0.001" thousands of an inch, or smaller, then the surface tension of the mineral oil will be too thick to bridge the gap, and would remained encapsulated in the case. If my bullshit technical synopsis is correct, then you just made this watch highly water resistant.😉
I have done the same thing in my a158 with red mineral oil (car transmissions fluid)😝 5 years now no prodlem! Rememder to put new batterie so you dont have to change oil too for the next 7 or more years
@@waris3732 I think its more likely for the oils that are already in the gaskets are gonna get dissolved by the mineral oil, and then it'll start to slowly leak
soooo hey I just had an idea what if you could have the light on always on a casio watch? it would be pretty cool to just look at your watch in the dark without pressing the button, but would it kill the battery really quick? cause these guys last like 10 years so it can't be that bad
The mineral oil can actually , over time, fray the rubber gaskets that seal the watch. There is special oil called silicon oil with 50% viscosity, called Fluorinert by brand name, which is certified to work with all electronics and used by corporations and the military for their advanced electrical products, from fighter planes to data servers. Also it is used for industrial applications like leak testing.
So here is what they don't tell you about doing this. Firstly, you'll lose the beep..the alarm becomes barely audible after this. Second your buttons are gonna get mushy and sticky and sometimes even dribble a tiny amount of oil on your finger when you press the buttons (the oil on your fingers gets transferred to your clothes) all this so you can go deep diving with your casio f91 that you will never do.
@0:09 I think we all know what you are going to do with all this money....

I wonder if there is fluorescent colouring, you'll never need the light again
damn brilliant idea
Sometimes my genius... it generates gravity
Yeah you can deffo get florescent inks, not sure if the medium it's suspended in matters beyond it not being water based
You can also add lume powder to the oil soultion. It wouldn't affect the coloring, but would cause it to glow in the dark like a Timex Indigo.
wow great thinking
I like to have the back cover submerged and pointing inside up before turning it over under the surface and screwing it on. Because it is embossed, it is really easy to trap air under it when lowering it under the oil.
Now give it to a watchmaker and ask for a batterry change :D
Para qué, si la batería dura más de 7 años y el reloj cuesta 15 usd
😀
If you can oil mod that watch then you can change the battery also, the problem is it will be messy.
Does the alarm still sound as loud (or work at all) when it's oil filled?
UV led replacement and fluorescent dye in the oil!

It doesn't. I had this question as well, it's one of the reasons I did this mod.
@@Techsas damn thats so cool :)! for a next project you could use oil with some phosphorescence liquid or powder so the watch glows in the dark :D

I wonder if this actually improves the waterproofing, since there's less pressure difference inside and outside the watch when diving
I believe so, Sinn did this with one of their quartz divers
In theory it can now go to ANY depth. No air inside to compress at a high depth means the case can't deform under high pressure.
@@spinnanz In theory? As long as the plastic casing doesn't break under pressure, it should remain water-proof?
