For those wondering why you might do this, the Hydraulic Press channel stuck an oil filled 200m rated watch in the test chamber and took it to the equivalent of 3,000m and it survived. Most 200m rated watches can go deeper out the box, but only to around 600m before the glass cracks or the case back collapses under the pressure. An oil filled watch with an electromechanical movement will suffer a severe reduction of battery life, so an all digital model or solar powered movement might be the best way to go. A solar digital watch would probably be the most suited for this type of modification. Lacking any bubbles inside the case, the watch will suffer severe internal pressure changes with heating and cooling. This may cause seals to fail prematurely as fluids are essentially incompressible and that excess pressure has to be relieved somehow. An interesting idea that can greatly increase the depth rating of a watch but probably not something that is suitable for an everyday beater.

After watching this, I went to eBay and bought an MRW200H and Microlubrol. I don't even really care if there's any actual improvement to the watch that I'll ever use, it's just fun to tinker and learn new skills. Cheers mate, should be a hoot.

Super idea, i bought the SDW Hypertec Shark with oil filling.

[@paulhopkins1905]

Really cool, I have a vacuum pump and a small chamber. I'm going to try this with vacuum

[@Pehr81]

I’d use a deeper container so the dial and case back can be rotated to get rid of bubbles. That’s use more oil of course.

[@Time4CakeAndSodomy]

Adding some uv reactive or glow in the dark dye to the oil could be cool

[@taz1807]

some times i did this procedure, i prefer to have more oil and a bigger container, where you can just move the watch pieces inside the oil in some directions, to send the bubbles out of the watch easier. Anyway, very good video! Thanks!

Glad to find you again - I’m still looking for a small bottle of Fluorinert 76 I think - but cheapest is about £50 for 500ml (way too much). As before, great vids BTW 👏👏👏👏👏

[@chuffmeister1130]

It might be the sun burst effect on the dial of that duro that makes it a little underwhelming, since it catches light differently under the different refractive index of the oil. Excellent video btw! Appreciate it

[@jlg395]

Really interesting stuff.

[@rchard6345]

really cool 👍 ..well done !

[@romeowhiskeyjuliette8711]

The MDV-106 doesn't "pop" because it's dial has very fine starburst etching that reflects light at all angles. It's really a cool watch for the price. Great job, bro. I'm confident to do my watches like that.

[@FullTimePRO]

Watches look great man, I was reading that you can put the MRW200H dial/movement into the MDV106 body, maybe try that next so you get the look of the 200 in the Duro body, might be worth a video :D

[@rafeadler1471]

Im glad you are back! You are one of the most unique channels on KZbin.

[@darakwatches467]

Hi Rafe, thanks, and welcome back.

[@boga92]

Thank you, Darak for this video. I think it's very helpful, and (as far as I know now), you do it quite properly. I already moded a Casio F-91 years ago, filling it with Olive Oil !. At the moment, still it's working quite fine. Visibility doesn't change as much as with analogics, but oil improves dramatically the submergibility of the watch. This just "water-resistant" Casio has gone diving with me down to 40 meters more than five times. And many more, a bit shallower. But now, I and a group of friends want to hydrolyze some analogic watches. First I decided to start with the MRW-200 that you fill here, because (as you say) the effect looks better than on the MDV-106. But after thinking about it, I'd rather prefer a watch like the Duro, with a screwed crown (even though a screwed-down case back is trickier to close than a case back with screws). I'm more confident about avoiding future oil leaks with a screed crown. Let's talk about the procedure. I like very much the box you used. I think it's the perfect size, and I hope to find something similar. I like also the way yo refill the leaking oil with the syringe. I guess that I will manage to close the screwed down back case properly (without leaving bubbles), and that I will set in position the crown, because I see that you close the case, before closing the crown. Is this to avoid excess pressure inside the watch, while you are closing the back, and let the oil leak through the crown's hole, in case of necessity? And finally, my biggest doubt: I don't see that you leave any bubble inside. The dial looks gorgeous in that way. But, aren't you afraid that with warmer temperatures, the oil expands inside the watch, and can cause problems (or leakings)?. In other oil modding I've seen that they leave bubbles (bigger or smaller), and (for instance) Sinn has patented a special piston for dealing with this issue. Tell me what you think about it. Maybe this oil doesn't expant¡d too much with the temperature changes. Finally, as I've seen in some other vídeos, I think that you are right with the density ot the oil. 50 cst seems t have the right amount. But I wonder why they don't use even less dense oils. If they keep the same conditions about conductivity, I don't see any problems to use them, and the hands would find less resistance in moving. Anyway, thank you for this vídeo, And I hope to read your answers.

[@darakwatches467]

Hi Boga92, thank you for your long and informative common, but you really should watch this video first, and we can discuss more, this is my follow-up video of the Hydro mod, kzbin.info/www/bejne/i6G8poCYl9xnmM0

[@boga92]

@@darakwatches467 I already saw the other video. But I find impossible fitting the styrofoam balls in place while closing the case back. Do you think it's possible to fill the case with silicone oil through the crown hole? Anyway. I think you didn't leave any bubble inside these two watches. How are they behaving? Any leak?

[@metallitech]

For the thermal expansion, perhaps the o-rings of the buttons provide enough flexibility. Would be interesting to calculate the change in size of the oil.

[@cobaltace62]

I have done this on two watches. Once on a quartz Casio Marlin and once on a Casio G-Shock ani-dig watch. Only do this mod on a fully digital watch. Even the thinnest silicon oil will add resistance enough to drain the battery on an analog quartz watch. On both of mine, with new batteries, they died in 6 weeks. After a thorough cleaning and fresh batteries, they worked fine. A full LCD would be great.

😛 ¡Saludos!. ¡Excelente video!.

[@genexstyle]

If you add more oil to a container so you can assemble the whole thing fully submerged you can never get a bubble of air. The results where surprising on the first watch! Really cool, wonder how the durability is affected by this :)

[@adamphelps2369]

My thoughts too, that’s what I plan on doing

[@Baruch-Hashem]

very nice

[@edbebop]

For added points do this on a glass table so you can see underneath ;)

[@ryanmontisnlp]

Great video! Thanks for making it.

[@jevs8188]

I´m not an expert either, yet i think you need a convex lens in order to get the full effect like the watch on this video. Also, looking for viscosity and interaction with materials might be the kind of oil your looking for. Secondly, experimenting with the refraction index of the oil, in relationship with the kind and thickness of glass you´re using might create a more desirable outcome

[@jpalacios117]

You could close that container and turn it sideways so that the air can go out through the crown. Maybe it would take a couple minutes though

[@felicianoabe]

Very interesting, I would imagine doing so would make the watch more water proof in a way, right? Also won’t the oil cause friction and delay the whole watch by a bit over time? Also what happens when you change the battery? I’ll you need to have extra oil at hand to fill to avoid bubbles during battery changes, also would this work with a mechanical watch????

[@Tootlew]

I wonder how much the weight changes. Thank you for the informative video.

[@fishesfromtupperware]

Nice vid and it works great BUT it eats batteries. I've done a few of these and the battery has lasted as little as a year. I'm guessing because the motor is using a lot more torque.

[@artempriadko6974]

solar movement is the answer

[@dbons_np]

I wonder if it work well in my Bulova curv. I’ve been thinking about doing it as I think it would really make it pop.

[@malitiemmanuel1321]

[@adsagp]

Great video, thanks for showing us how you did it. Did you oil fill the digital watch too? If so, can you press the buttons when submerged under water? Does the light still work?

[@BarisEksi]

You made them super water resistant

[@TheFlyrodder68]

Can one do this to a solar-powered watch? I ask because I don't think I'd like to do a do-over every time I need to replace the battery. If not, I'd recommend replacing the battery with a new one before doing the mod to make it last longer before the next reapplication of oil. Nice video and thanks! Thumbs up!

[@truenorthmuskoka9077]

Ok looks great but how do you adjust the time

[@joshhudac7076]

I sell silicone fluids and might try this with something with a lower viscosity. I’ve got 0.65, 1.5, 5 that might work better

[@MiguelBricaBrac]

Don’t you need a high torque movement to compensate for the fluid density and avoid the gearing and step motor from wearing out prematurely? Also, when you adjust the time, does it leak?

[@sorcer888]

great stuff but changing battery will be a pain, at least it is not going to be that often

[@kubicajakub]

I wonder about power usage increase due to higher resistance of oil vs air ... and how you will change battery?

[@DePistolero]

Does the watch tick slower when oil inside? it seems as if the seconds hand is a bit more "lazy". Don't know whether this affects the timekeeping...

[@tissapathiratna7761]

Will oil create a drag on gear train.? & Stepper motor !

[@Jamboliner]

I reckon we have great results in both cases. The digital did not. The thing with the other two is that one of them has numbers to pop which the metal one has not.

[@rainnelmaclang4803]

I wonder if the movement of the Seconds Hand and the mechanical gears, while they move through the oil, would create enough drag to make it use up more battery power, and shorten the battery life?

[@rainnelmaclang4803]

I learned from other videos that the electric current draw of oil-filled mod is 3-4 times more than the original non-filled watch. This is due to the drag that the oil makes on the rotating parts, demanding more power from the quartz drive. So expect your batteries to run down faster, meaning, if the original watch will run for three years before it needs battery change, the oil-filled one will last only one year or less.

[@thomaswitkamp3138]

[@johnnemo6509]

The Duro MDV-106 has 200m depth to begin with, I wonder if anyone has put a hydro mod Duro in a pressure chamber to see what its depth rating is? I saw one video where a hydro mod Dive watch with a depth rating of 300m (without liquid fill) continued to function at 1000m (with liquid fill). I think you chose the right silicone oil for the job 50 cst is low enough viscosity (though lower might be better if obtainable) Silicone or poly siloxane based oils are good because they have a very high wetting coefficient , do not conduct electrically, and should not attack plastics. I think I'm going to try this on a MDV-106 and a MW200. Thanks!

[@AtayMLG]

theoretically oil filled watches go as long as the depth goes. you can find a video of a Pulsar oil filled watch going 3000m in a pressure chamber.

with Mine?..I made a "Rolex Submariner" style watch into a Oil filled to test it, it has a rubber O-Ring on the Crown shaft though not just a metal on metal seal... it seems to hold everything back OK when I change the time/date, I could imagine some air working its way into the case eventually with multiple changes...but so far?..it's held up ok!.

[@mrmagoo.3678]

​@@daalvares if you angle the watch correctly when changing Date/Time (crown pointing UP/High) then You should be OK for a FEW changes, eventually though?.. air would work its way into the case with Multiple changes, but that's a quick painless fix.. 10 mins every 6 months?.. MAX!

Newbie here asking a question, will the watch still keep time correctly due to the increased resistance of the oil against the seconds hand?

I imagine pulling the crown out would create negative pressure that would suck a little air bubble in past the O-rings, then pushing the crown back in would either compress that bubble or push oil out.
