You make this far more difficult that it needs to be. Keeping a single air bubble adds to the effect but getting one the correct size can be difficult. Eliminating all air above the dial however is simple and there's no need to immerse the watch to do this. Just set the watch on a paper towel, add oil with the syringe and drop the dial down. Check for bubbles and expel any by tipping the watch and pressing on the rear of the dial face to force then out. You'll see this happening as the face flexes. Put in the crown and battery, top of with oil and fit the spacer. Top up again, squirt some oil on the case back and then lay it down before tightening the screws. On cheaper Casio watches I just lift the face and use a syringe to add the oil without removing the battery of crown. I have a number of different colour Duros and whenever I do this always change the crystal to sapphire so have to remove the movement and dial but I bet you can still do this. From experience, whenever I've got the bubble I like on the front too small, it can vanish as it gets between the dial and case. Large bubbles at the rear however, never seem to get to the front.
Hi dude..good vid. Just as a case in point...you can reverse the process should you decide to go back to as new....... The case and movement can be cleaned using lighter fuel.... obviously soak and rince case with fuel then just dish soap and water....and with the movement simply immerse in lighter fuel.. flip flop it around... Pour more over the movement..then repeat using clean fuel....leave to air dry which will happen fairly quickly and you are then totally oil free👍 This is from a lot of experience....in my early stages of hydro modding I went through quite a few watches and found that not all quartz movements are not made equal..and so some of the hands stop moving due to them being friction fit..... Oil and friction are not buddies!! Ps...Zipo I found to be the best....hope this helps guys.
thanks for posting this, i just ordered my Duro and may try this. may use a mirror on the table (or my phone facing up) to help me check for bubbles. if i try lifting it up and looking underneath i just know i'm going to spill it on my face :)
Maybe if you use dielectric fluid used for computer immersion. When they immerse servers and bitcoin miners in that fluid, they stay immersed for the life of the equipment. The fans stay in place as far as I'm aware and I havent heard any issues about wear on the fans.
Great video. I like the way the watch looks like when done,but, I would never do this knowing I have to replace the battery sooner because of the oil. You made it look easy but this can turn into a complete mess if your clumsy.
Hi mate, What is the stainless bracelet you have on the blue one, it looks amazing, I would like to buy that one, which brand and model is? Any link? Much appreciate it
Perhaps you could mod it by replacing the movement and dial with one from the similar casio solar movement watch that does not have the movable bezel MTP-S110-2AVCF so you can have the best of both worlds.
Thanks. It can be ordered at the link below. Just fyi, it's a tight fit onto the Casio Duro, and i had to bend the spring bars to make it fit. www.amazon.com/dp/B07WFSX7JM/ref=cm_sw_r_cp_apa_glt_fabc_MTPH6WBMW4A3KCXK65NP?_encoding=UTF8&psc=1
Is it still work ? Can you tell me effect oil to hardlex crystal or saphire ? Can oil can make hardlex crystal become yelow or blur after long time use ?
I've just bought a litre of 5 cSt silicon oil to try something just like this. My hope is that the much lower viscosity will help negate air bubbles and be less of a drag on the watch movement.
@@watchncarry9593 I know the problem. It was going to cost me a bomb to import a small quantity from the States and all I could get locally was ordinary silicon oil that was about five times heavier than MicroLubrol. After some searching I found a place that had it in all sorts of viscosities. I got the second thinnest. They apparently do a 0.65 cSt too but I thought that might be a bit much. And as it is a litre cost me $88. I didn't bother asking about Fluorinert. That has to be more expensive. Anyway, nice video, thank you. I'm picking up all sorts of tips. Keep up the good work.
@@brotherandrew3393 Yes, I've already put a new battery in since then, and it's now stopped again. Worthwhile experiment though. Still a pretty good mod for digital watches.
you should do this on a watch with a very domed crystal like the timex Q or marlin or a quartz black classic orient that has a domed crystal or a swatch red grin... maybe there are some budget friendly domed watches on aliexpress that have a black dial just to see the dial float on that curved dome..
Good question. If youre referring to the pulling out the crown to adjust the date/time, no, this will not introduce air into the watch case. There is a small o-ring in the stem of the crown that prevents this. If you do this mod, it's sometimes possible to develop a very small air bubble (like the size of a pen tip or pencil eraser). This air bubble may not show itself initially when you complete the mod, but then suddenly appears when the watch has been sitting unworn for several days (this is because the oil is uaully warmer when youre completing the mod since it's being exposed to room temperatures and being manipulated around by you). When this happena, id recommend just wearing the watch for a few hours. Your wrist body heat will warm up the watch case, which in turn warms up the oil, and causes that air bubble to disappear. The air bubble will reappear though once the watch is left unused, and the oil temp returns to a lower temperature.
I have enjoyed your video. I did this mod on my Casio Duro. I really like the looks of the dial. It now loses time, like 10 secs per hour, and sometimes stops. Any ideas?
@@miversen1 i put in a new battery when i mine, also using 50 cst. It's been 4 months now, and battery is still working and time is accurate. But maybe 50cst is too much for some reason. I cant find anything less viscous, but id think a lower viscosity would help
Easiness is relative, and while a DD sapphire is cool, it's a completely different effect. Apples and oranges in terms of mods. That being said, i do enjoy the DD on my gold duro.
The problem I've faced with that particular Casio is battery life. That tiny battery lasts about a year and a half. That short span is disappointing. I wish Casio would use a higher capacity longer lasting battery.
The battery wears out in around six month. Changing is no different and you simply top-up the small amount of oil lost. This video makes everything ten times more difficult than it needs to be.
After 15 months o had to change the battery. During that time, it kept accurate date and time. Definitely a pain ti change the battery, and dint think ill do this mod agan lol, but was a fun experience nonetheless
Yes, as mentioned in the video. Possibly sooner than 2 years due to increased fluid resistance and thus more battery demand. Probably easier the second time around though since you wont have to remove the watch face. Just pop off caseback, replace battery, and fill back of watch module with more silicone oil, then rescrew caseback Not the kind of mod for someone who doesnt want the hassle
@@watchncarry9593 I’m a respiratory therapist. Love watches. I rarely see a “real” watch anymore. Even all the super wealthy docs are wearing apple watches and fitbits. I dig that olive green strap. Subbed!!
@@oldfashionedsportsmanchave4590 thanks for the kind words, and for all you do for our patients. And yeah, not too many watches I see anymore in family medicine.

The watch is already rated at 200m depth for diving! Why go to all this trouble to try and increase its depth rating??? No one, literally no one is going to get near the depths this watch is rated for. Just cannot see the point of all this. Good quality video though, LOL!
I already mentioned in the video that while some people do this to increase the depth rating, im purely doing it for looks (crisper looking display and better viewing angles). Yes i know this voids warranty, and can add wear and tear on watch, as already mentioned. So clearly not a mod of interest for people like you. Ignore it and move on, LOL!
So, every battery change is also an oil change? Yeah, the benefits do not outweigh the fact that the movement was spec'd, designed and built to operate correctly in a non liquid environment. This is dumb unless you are a deep sea diver and are too cheap to buy a dive computer.
Youre an idiot. I mean feel free to disagree, but dont need to be ass. I literally mentioned the cons of this mod at the beginning of the video, and stated that this is mostly aesthetic and puts risk to the watch. So proceed at ur own discretion!
@@watchncarry9593 I literally clicked and watched the video and helped you out with a like, a comment, and a sub regardless of this dumbassed mod. I guess I am an idiot and an ass as you say.
No one dives without a computer now even when recreational diving. The advantage is the exception clarity as the refractive index of the oil matches the crystal. That's probably a little complex for you to understand so try and find a grown up to explain. Changing batteries is no different and only a small top-up of oil is needed.
@@byteme9718 I'm more grown up than you. If I don't like something I say so and say why (my opinion). Wrong or right doesn't really matter. Being honest is a lost value here on UA-cam, I guess. Find a grown up to explain to you that you don't have to like everything, and you don't have to be a kiss ass to the channel. Your absolutism, is not good for anyone, especially youtube.
@@Tom_H327 This was my first visit to this channel. You missed the entire point of the mod despite it being made clear. I guess being "more grown up" is still using a pocket watch. This is cheap, easy and takes around 15 minutes. In contrast, if your want to buy an oil filled mechanical watch, you're looking at an entry level of £33,000.
I wish they would have put a holder for a big 2032 battery in there. It would run for 20years.
Than engineered bracelet looks sick! love it!

I was able to resurrect an old Timex watch that didn't take well to the hydro mod.
Much appreciated...
Use Florunite oil, it is runnier than silicone oil and silicone oil will turn white things yellow overtime including lume.

Yeah. My black Duro has one decent size air bubble. Done on accident, but think ill keep it 👍
What are the straps and bracelets on those duros,?

No cotton balls. Use a coffee filter if you re-use oil
