I was todays years old when I learned about hydro-modding a watch and not only that, I find a guy that's got test equipment. I have no idea why KZbin brought me here, but it was a decent use of my disposable free time.

[@LaOwlett]

I don't know how I got here either. I was looking for a watch with an accurate barometer. I will never need an oil filled watch, but I needed to see one implode. My time isn't disposable, but it is what it is. lol

Whew! Until seeing this, I was worried about diving past 1500 meters with my oil-filled watch.

[@juancamiloza]

Yeah. Luckily next week’s dive is only 1450 mts

[@paraglidingprospector]

@@juancamiloza Also… this was a very well thought out video and the amount of work put into this was likely many many hours in the making too. Thoroughly enjoyed the journey! The cracking of the internals prior to the face-glass was unexpected! 🤙🏼 I’ve got an old dive watch, but would never think of filling it with oil. Hah!

[@kobusvanrensburg4092]

I've been a commercial diver for over 23 years, this last year spent as a "deck jockey". I've used a Sub, a Tuna, an Ecozilla and a Sinn as my back-up to my dive computer. I switched to using my silicone oil filled DW5600 around 2010-ish. It's a mess during battery changes but my DW has survived literally hundreds of dives.

[@TheDropzoneChannel]

Wow. Thanks for sharing! If the pros are using this method then it must be legit.

Thanks man I was afraid my watch wouldn't make it during my 3000m dive next week.

[@jackochainsaw]

You have to use a very thin oil in this mod (Type 200 50 CST Silicone Oil as an example). In addition with oil mods like this, with quartz watches, you significantly reduce the battery life. The hands have to work harder to push around in an oil filled watch thanks to a change in the fluid dynamics (more drag just like when you are underwater). The cool thing about oil mods is that they reduce refraction so the dial is considerably more legible and can be viewed from extreme angles. It is messy to replace the battery, and you may need to top up at that point. Getting oil out of an oil filled watch is very difficult so this is pretty much a 1 way modification, you best like it when you've committed yourself. As some have mentioned if your watch is in a warm environment, it can expand and push oil past the pushers. Ideally you need to keep it around ambient room temperature or below. In the sea, you shouldn't have a problem keeping it cool enough. When oil gets warm its viscosity changes. Another annoying thing with a mod like this is a potential air bubble that you may have difficulty removing. U-Boat, an Italian watch company, have designed their watches to have a separate battery section from the oil filled inner watch to make those battery changes a bit less messy. Their watches tend to feature an air bubble for a bit of fun but I'm sure many people with OCD would find that infuriating. I enjoyed the sudden explosion in this vid. The watch didn't really function as a watch should past 700m but to be honest, only saturation divers are going that deep.

[@TheDropzoneChannel]

Lots of good details there. Definitely going to be trying it out in the future. Thanks!

[@carpandrei7493]

I saw some videos about oil filled watches where the guys used Styrofoam beads as a way to compensate for temperature differences.... On a side note... I wonder how well would an oil mod work with a solar powered watch... no need to remove the battery for a looong time.

[@richardkudrna7503]

Long long ago my job was to enhance the weather resistance (water ingress) on the wiring harnesses used on aero engines. Water can arrive as rain but also those portions not heated by the engine will cold soak at altitude then form dew and on descent the increasing air pressure would drive in the water. Any defect able to admit air, no matter how small) would carry in vapour and with altitude cycles, the moisture would accumulate. Finally I met an older designer at a skilled supplier who showed me his harness as used on submarine launched missiles. These withstand a sudden exposure to seawater at (classified) max launch depth and transfer data to the missile. I was in awe. How did you achieve this??!! I asked with my eyes wide. He answered “first you must be humble, and you must accept that any void in your design, nature will fill with water”. Exactly as you have demonstrated here.

[@dunderhay9169]

The standard G is incredible, anyone wearing it would be dead long before the watch stopped. Although the hydro modding works as intended, it is pointless from the depth perspective, but might be worth it for appearance. Cool video, thanks 👍

[@TheDropzoneChannel]

I think the commercial diver that commented right after you would beg to differ... lol

[@stevenkelby2169]

Pointless how? It guarantees water resistance to any depth. You'll never have to worry about it.

[@BoleDaPole]

That's like saying buying a ferarri is pointless because you'll never drive it at top speed.

[@dunderhay9169]

​@@stevenkelby2169The deepest dive by a human is 332m, the standard G-Shock stopped working at 400m. Consequently, the watch is capable of going deeper than any human in its standard form making the oil mod unnecessary from a depth perspective.

[@dunderhay9169]

​@@BoleDaPoleI don't think much of your analogy, with super deep dive watches any diver would be crushed long before the watch, if you were guaranteed to die long before reaching the top speed of your Ferrari, would you still consider it a desirable feature of the car?

[@BadMonkey6000]

This is great info, thanks! I have broken three Casio G-Shocks when I was snorkeling deeper than 1,700 meters, one imploded at 1,700m, the other at 1,800m, and the third at 2,100m.

You cannot snorkel at 1700 meters. 20% atmospheric oxygen becomes toxic at partial pressures of more than 2 atmospheres, 80% nitrogen becomes an anesthetic agent at high partial pressures.

@4:18 - I was getting irritated with the clicking and popping in the video - till I realized that it was the WATCH making the clicking noises. Then I went from annoyed, to realization, to rewinding and watching again after commenting. That's a very cool demonstration so far.

[@elin_lyze]

I learned about oil filling when getting a cheap Casio F91W. I saw a forum post (TZ-UK, "The Little Watch That Could ") of some guy on an oil rig dunking one filled with olive oil at 1km depth for 3 days and the thing surviving fine. I since use a silicone oil filled F91W with a simple Nato strap as an everyday watch (in case I fall into the abyss idk) and it's really nice to have a watch while swimming that I can 200% rely on. Even got the more fancy gold steel vintage one because I just kind of fell in love with the watch in general thanks to this experience! It's super cool to see you actually pressure test some watches like this and to read some comments with actual reports of irl use. I would LOVE to see you test an oil filled F91W! They are cheap and reliable friends :)

[@TheDropzoneChannel]

Thanks for sharing that post! That might've been the first time a hydro modded watch has hit those depths in the deep ocean. Very cool test. I've added your suggestion to the list. It's much cheaper than the G-Shock which is good.

[@Tobi_Jones]

very cool experiment, interesting to see the mod worked so well

[@maxmixer]

I always wondered about my U Boat Capsoil, but that tiny air bubble might cause an issue, anyway great video and new subscriber :) (Were the internals fully working after the depth test on the oil filled and what actual oil was used on that one ?

[@Slowpode]

Did you notice that the minute hand does not move on the hydro moded watch, even before starting the experiment?

[@TheDropzoneChannel]

Very observant! The minute hand actually moves but really slowly. It was a botched modification hence the donation I guess... Beggars can't be choosers.

[@plektosgaming]

@@zachvalue The issue is the buttons pressing in on the board, which would mean in this case both failed (or would have) at about 40bar. The digital display didn't crack, though. So this might be a good mod for a purely digital design.

[@plektosgaming]

@@zachvalue The first watch failed initially because of the pressure of the buttons pressing in on the circuit board. The second watch and many others likely will have the same issue. Also, the back was caved in, which also might cause stress on internal components. More testing needs to be done as "surviving" means nothing. It's how deep can it go without suffering permanent damage of any kind? I suspect that a modification like this won't really help most watches.

[@plektosgaming]

@@zachvalue This mod is definitely for digital only watches where it does seem to help at least on clarity.

[@TrailBlazer5280]

yes viewing angle is really the only benefit i see people talk about online. i can imagine depth would also be helped since the pressure is on a liquid not a gas causing the case to flex less

Great video... I learned fluids can't be compressed (kinda how hydraulics work), so by replacing all the gaseous molecules from the internal cavity with fluid, the container (watch case) regardless of how thin, shouldn't collapse, even under the most extreme external pressures, theoretically speaking. 🤔 I'm only guessing when I assume the reason why the above watch collapsed, is because the internal fluid does not completely remove all gases from within the battery, LCD screen and internal moulded plastic support frame, which will likely compress and invariably compromises the integrity of the weakest point, the glass. The recent 'Titan' disaster suffered a similar catastrophic fate, when it's internal 15psi 'atmospheric' couldn't withstand the 375+ atmospheres of forces trying to get into that carbon fibre cigar tube. It was all over before a single human neuron could even begin to perceive that kind of implosive event. (My sincere condolences to all the loved ones they left behind). This is just my opinion, I could be wrong.

[@ChrisSmith-rm6xl]

I had the same question. Where did you get a high pressure microphone? Or are you listening at the outside of the chamber?

[@shadyarian]

I'm also interested in this. Personally, I'd just record the pressure sensor itself at audible sampling frequencies.

[@n7titan243]

I tried adding olive oil to my cheapo quartz watch and the second hand now doesn't move lol. I can see it ticking, but it's stuck in place at 17sec. Good thing I tried this on a cheapo, maybe if I take the second hand off it will still function?

[@fiery_transition]

Dude, you can see the rubber housing shrinking :-D

[@davidellison4750]

The air purged hydro modded watch should be resistant to increasing pressure and continue to keep time until the small cylindrical can containing the quartz crystal is crushed. For the person worried about the incompressible fluid in the modded watch not allowing the press of buttons, there’s enough flex in the case and case back to allow button presses although there’s somewhat more effort involved.

[@FazerWiz]

I filled a citizen ecodrive watch which means it never needs to be opened to change the battery. Great idea, but if the watch gets warm (in direct sunlight for example) the oil expands and pushes its way out of the seals, out leaving an air bubble when it cools. I wonder if there is a way of including a small compressible price of rubber that would solve the issue...

[@davidellison4750]

With some hydro mods, a small piece of air containing foam is installed inside the watch, this allows some expansion of the fluid with temperature. The fluid isn’t compressible at reasonable pressures but it will decrease in volume somewhat with decreasing temperatures. That bit of air allows for the small changes in volume. It’s interesting that if a small air bubble is visible through the crystal, when the watch is warmed, the bubble will shrink and when the watch is cooled, the bubble will expand. This is opposite what one might initially think would happen. It’s because of the change in volume of the fluid. The air bubble responds to the change in pressures due to alterations in fluid volumes. These pressure changes outweigh the effect of the temperature changes on the gas.

[@Hellefleur]

That G-Shock is beautiful! Only $88 currently too!!

[@LungsMcGee]

I have Sinn, a mechanical one so only rated for 1000m. Sinn claim the actual depth rating of the oil filled models is unlimited, however the working depth limit is 5000m due to increased internal pressure of the oscillator crystal causing it to stop working. Pop back up above 5000m again and you’re good to go. Apparently.

[@maukka138]

Sinn❤

[@beardymcbeardface69]

"due to increased internal pressure of the oscillator crystal" Bingo! This was exactly my theory. Time keeping crystal oscillators are housed inside hollow sealed enclosures. With 1 atm inside that little housing and many many times that outside in the oil around that crystal oscillator housing, that housing will be getting crushed.

Very interesting and do like the added visual benefit but wonder if the oil is adding resistance to the mechanical moving parts throwing off its accuracy as well as shortening the battery life due to that resistance. Would like to see a follow up test via confirming all those data points. Thanks again and looking forward to further discussion.

[@TheDropzoneChannel]

The mod did slow down the minute hand on this watch but other hydro mods seem to be fine. The watch model is GA2100VB-1A.

[@Sapetoku1]

I have hydro modded various analog watches, some with great results. One thing is a constant though: battery life is cut short because of the increased resistance the hands experience, being forced to move around in oil. I used rather thick mineral oil, it probably works better with a less viscous oil. The visual effect is very appealing!

[@searchandsave142]

@@TheDropzoneChannelthank you

[@davidellison4750]

One would think the battery life is related to the viscosity and it is, but the watch uses a stepper motor. In general stepper motors are a one way device and don’t return information to the controller. As such the controller shouldn’t “know” about the increased viscosity so shouldn’t know to provide extra current. Steppers without feedback loops will either step or not step but the controller never knows. If there is a feedback mechanism then the controller would be able to respond to the increased resistance to movement. Since the battery life is decreased, there must be feedback to the controller. This would make the stepper controller and stepper much more sophisticated than I had assumed. My batteries in hydro modded watches tend to last 4-8 months, far short of the 3 year battery life in the un modded watch.

[@ThisIsTheInternet]

im curious how my watch would fare considering it has almost every part of it moving on the inside but it was part of a limited run and was fairly expensive even before currency conversion i will instead imagine you destroying my watch while it instead "safely" sits on my wrist

[@christiankirkenes5922]

I would argue that both watches actually only made it to 400m because that is when they stopped functioning.

[@Necropolis_08]

I want to replicate this mod. How did you do it?

[@NoxmilesDe]

I need to oil my watch. I don't need it, but i WANT it 😂

[@plektosgaming]

So, based on the first test, 40 bar before it stops keeping time seems like a fair safety margin of 100%. This seems in line with what you would expect. The problem here is that the other watch isn't exactly clear at which point it also stops working or has deformed. I would think that it would be exactly the same as the issue here is that the buttons are pressing in and causing damage to the internals, which the oil wouldn't exactly protect against. You can see that when it goes to the next minute ( at about 1500psi ) the hand isn't moving. So the watch won't stop working in theory if modded, but protection against damage... depends on the design I guess.

[@beardymcbeardface69]

Exactly. Anything compressible inside the watch, will be crushed. So my first thought are any electronic parts which are hollow and sealed, such as IC's and quartz crystal oscillators. If their internals are at around 1 atmosphere and the oil around them is at X times 1 atmosphere, those internals will be getting crushed. So I am curious about the LCD in this, cracking first. Given that LCD's are sandwiches of thin sheets of glass, with LCD liquid inside, spaced and sealed around the edges, this makes me wonder in the LCD liquid is compressible to some degree, leading to the glass sandwiches flexing til breakage.

If you were to be preparing for apocalypse, a hydro modded g-shock just might be it. You might not survive, but that damn watch on your wrist will keep ticking!

[@Mikes_momo]

make sure its a solar powered version

[@georgehofgren6123]

Not if you die and land with the watch face down. ...I'm afraid we need Nuclear powered- ​@Mikes_momo

Think I can hear the atoms breaking bonds. That’s a scary contraption.

The hands have stopped working on the modded one I see in your video. I tried hydromod with a casio that had moving hands. I used some supposedly thin oil used for example shock absorbers for RC cars. I think if you cannot get that very thin expensive electronic insulating oil, you should use it only on digital clocks.

[@Twowheelgoblin]

I have the exact same gshock. time to go do this. Great video! you got a new sub!

[@PKPhoenix83]

Me too. Cool watch, wish the lume was better though.

[@TrueGamerX14]

that headphone warning really helped haha

I'm gonna have to investigate this as a method for preventing glint for tactical applications.
