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 CZcams brought me here, but it was a decent use of my disposable free time.
@@moneybilla
weird... a firearm video brought me here too.
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
A cz p10 c takedown video brought me lol
Whew! Until seeing this, I was worried about diving past 1500 meters with my oil-filled watch.
Yeah. Luckily next week’s dive is only 1450 mts
@@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!
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.
Wow. Thanks for sharing! If the pros are using this method then it must be legit.
Now tell them to what depths you used it, because that's his confusion.
My dad was a dive instructor, I've got his old DW260 that's got over 10,000 hours dive time and still running a treat.
Casio's are the goat when it comes to dive watches imo
@@17cmmittlererminenwerfer81 usually 50-80m for the bulk of dives.
What if you had a GW instead of a DW because it's solar?
Thanks man I was afraid my watch wouldn't make it during my 3000m dive next week.
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.
Lots of good details there. Definitely going to be trying it out in the future. Thanks!
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.
😮
imagine if they had included a shot in James Cameron’s “The Abyss” where a diver lost consciousness and fell to the point where his watch imploded. chilling
Pretty sure that shattering dial faces due to pressure buildup is a common trope.
@@MikeStavola i remember gauges on the submarine shattering in the film U-571 starring Matthew McConaughey. If you know other good ones i’ll be keen to watch them.
@@JinKee U-96 "Das Boot"
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.
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 👍
I think the commercial diver that commented right after you would beg to differ... lol
Pointless how?
It guarantees water resistance to any depth. You'll never have to worry about it.
That's like saying buying a ferarri is pointless because you'll never drive it at top speed.
@@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.
@@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?
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.
lol snorkeling at 1700m? Right
That must be a big ass snorkel then
😅u have to be kidding right?
Long snorkel
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.
Wow! 🤯 Thanks so much for putting a Hydro Mod to the test 🙏
I’ve got one Hydro Mod under my belt, and have more videos planned in the future - Now with added confidence thanks to your test 😁
I would never have thought that hydro modding would make such a drastic difference!!! What a great video was not expecting to see such advanced equipment be used for testing, earned a subscribe from me.
So glad this channel appeared in my feed. I’m not a diver and don’t have the physical capability to, but this is fascinating to learn about. Great video. You’ve earned a sub
That is a very impressive modification! I would like all my digital watches filled with oil. Thanks for this video.
The vintage G-Shock image, at centre, in 2:40 really took me back to the late 80s and 90s when I had one for late high school, and uni, and then my first job. Now I feel old haha.
It's not a vintage, it's the GW-M5610 (or 5610u), it adds tough solar and multiband 6 at the shape (and colours) of the first G, try it and you'll fall in love again 😄
Mighty impressive the depth at which it started to fail and ultimately failed. I thought it would be all over at 300m
That was my thought initially as well. I didn't realize it until now but the steel case back was deformed inwards but the seal still held. Maybe next time I'll open up a watch to see if anything gets crushed inside...
A proper autopsy is indeed a good idea, see how much damage the implosion caused in the inner mechanics and electronics.
@@TheDropzoneChannel Some of the fancier G's have a thicker case back and the fanciest have a screw back. I've got a few here but I"m not quite ready to send one to be imploded.
Amazon has a billion products that claim various levels of water-resistence: cameras, watches, flashlights, etc. Test em all.
Okay. I'll dedicate the next episode for you. OEM vs Chinese knock off GoPro underwater case...
@@TheDropzoneChannelThat will be a good one. Will there be a gopro inside the case recording?😅
@@VoeVikingAnybody out there want to donate a Hero 9, 10, 11 or 12 to science? lol
But please also fill it with oil
I love how specific this video was. keep it up
Interesting vid. I replaced the og mineral glass with a blue AR coated saphire. And then hands.. and then made my own lume recipe and painted the indicators😂... Great journey to casio mods.
I think the next step is to build your own watch from scratch.
Really enjoyed the video and analysis. Really cool that this mod is actually functional! Just a head's up, please give some sort of headphone warning in the future when you play a loud cracking sound. My ears rang a bit after the slow mo segment lol.
Thanks for your feedback and good vibes... Apologies for the slow mo, I'll bring down the volume and add the warning going forwards.
Very surprised how it far exceeded the pressure ratings. What a great setup for your pressure rig, really like the view and the digital display.
Bro. Don’t take this the wrong way. Your deadpan and monotonous presentation style is strangely humorous and entertaining at the same time.
I love it!!! 😂
It’s probably an Asian thing. I’m Asian too. Subbed. 🙂
Thanks for the sub! It's definitely not everyone's cup of tea.
and you just got a sub from me, i havent even watched the video yet but i love to see a channel that is UNIQUE! every yt channel these days is the same ...bravo my friend! cant wait to see this video
Impressive! I learn something in every one of your videos. 👍🏼
@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.
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 :)
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.
very cool experiment, interesting to see the mod worked so well
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 ?
Did you notice that the minute hand does not move on the hydro moded watch, even before starting the experiment?
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.
@@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.
@@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.
@@zachvalue This mod is definitely for digital only watches where it does seem to help at least on clarity.
@@zachvalueI have some 1 cSt dimethicone I want to try. That said, an MRH200 ran for about four months with 100 cSt oil. Kept perfect time, just ate through the battery.
Awesome and interesting stuff. You got my sub. Work on your presentation and probably try to speak a bit more and about what you are doing and I guess your channel will going great. Also some kind of a focus on watches could be interesting or "waterproof" products at all :)
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
Now that i know this is possible, i feel a primal need to open my watch up and do this.
Never mind that i never ever dive any deeper than dunking my head in the local lake, thats not the point! lol
You're channel is awesome. Keep it up.
I work with hydraulics quite a bit. I am flat out shocked that these watches can withstand anywhere near these pressures. This is incredible.
Can you simulate the potential added pressures applied from a swimming motion? Static is one thing, but would be interesting to see the numbers that would mimic a divers hand motions?
" dont do this to a mechanical watch, it will throw off the balace wheel" that's exactly what i was thinking too
I got question. If you hydromod a date watch, would it mess up the liquid if I were to adjust the date?
Maybe they should have filled the OceanGate Titan with oil before they went down. Just saying.
Duuuuuuuuuuude LMAO
Sadly, the oil is not very good for breathing in
Bluetooth controllers don’t work well in oil
Deep fried burgers ? 🤔
Thats crazy dude! Crazy underbite. Cool video though. I learned a lot. Thank you
Hey. I have a question. Will this mod effect how efficient the solar charging properties of my G shock?
Very cool video. Did the minute hand continue functioning on the oil-filled watch? It looked like it may have gotten stuck during the experiment and stayed that way.
6:21
@@halua1969ok but it never moved even when the water hadn't fully entered the chamber yet.
What are the chances! I was thinking of getting this exact model on a nato strap.
Excellent video! Thank you for this very interesting scientific experience.
Whoah mind blown. This is my first time seeing a hydro mod. And that pressure chamber.
I have a question about the Hydro Mod on the G-Shock GA2100.
Do the alarm tones still work with a Hydro Mod or are they no longer audible?
I would wager the alarm sound would be very low, barely audible.
what oil do you use for modding?
idk why im here, i just watched this watch fucking explode or something holy shit
it was actually entertaining
This was awesome and super fun to watch!
greatt quality videos, and i love the test equipment and really good data presentation
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.
should have filled the sub with mineral oil
@@ye1o881 Don't you mean they should've filled the sub with people who were smart enough to survive the experience. 🤔😂
2:42 what is the watch in the top center of the grid???
I had nooo idea!? Then again I'm not a diver.🤣 Also, there isnt any way in hell i would do that to my G shock. 🤑 Very cool video brotha.💯
Fantastic 10/10 A/V. How did you record the audio? With a transducer mic? I can't believe how many low frequency vibrations were going on. Was a treat for my subwoofer. Interesting how the low freq vibes increased in amplitude as the pressure increased.
I had the same question. Where did you get a high pressure microphone? Or are you listening at the outside of the chamber?
I'm also interested in this. Personally, I'd just record the pressure sensor itself at audible sampling frequencies.
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?
Dude, you can see the rubber housing shrinking :-D
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.
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...
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.
That G-Shock is beautiful! Only $88 currently too!!
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.
Sinn❤
"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.
@@beardymcbeardface69 Did you also know that if you introduce a crystal oscillator into a helium atmosphere, the helium will seep in and stop it from working?
@@LungsMcGee Oh wow, I did not know that. Very interesting!
Do you think those billionaires that went to see the titanic would have benefited from buying the upgrade? 😮
Very cool!!! Thanks for the video!😊
Thank you very much for the clarification, I was worried about taking my Casio F91W on my next visit to the Titanic with OceanGate.
omg, how in hell do you have only 4k subs.. i'm here since the balloon vid :)
Thanks for sticking around. We're just getting warmed up...
Because it isn't only the good informations and stuff like that that is important. It is also some kind of a how it is presented. So If he is working a bit on the presentation and also trying to catch up the viewer more this gonna be a very nice channel in this field.
at 5:19, that's how instant the Titan's implosion was, that's crazy
In the future, please lower the volume at moments like 7:04 or something. Otherwise great video!
Is it really that useful to go that deep when the hands stop working long before you reach the limit at which it would break?
this is a certified "Damn"
keep it up!
Ahh..Yes...My all time favorite Gshock 2100...The Virtual blue one 🥶
All of my hydromodded Gshocks are dead after 5 years. My stock ones are still going. I’m guessing the silicone oil becomes conductive after a while, so you’d have to change out the oil every once in a while. Tbh it’s so messy to do I wouldn’t want to do it more than once, but ymmv.
Would hydromodding work on a solar powered watch? If so, there would be no fear of messy battery changes.
Yes, it works great on the 5600 and 5610 casio solar watches. I have done two of those specific ones using silicone oil
I did this to a casio duro (silicon oil). It was brilliant until it stopped working a week later.....
Ive got one, and it is a beautiful face, but the battery ran out in about 6 months and i havent worn it much since haha. Gotta buy the gear and give it a go myself
7:03 that hurt my ears!! can you not?
Won’t the oil ruin the lcd over time?
More watches! Love it
Awesome video thanks 😊
Holy jumpscare at 7:02 💀
Can you do this to a Bluetooth solar casio
Any way you can test on the omega ultra deep it's rated for 6000m
"throw off the balance wheel" A bit of an understatement...
This is still a thing? I wanted to do this to my watch back in the day I never could though
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.
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.
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!
@@TheDropzoneChannelthank you
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.
Why does the minute hand never move on the hydro mod watch?
It does but very slowly. It was a botched mod.
I just subscribed . Cool channel and cool video.
Thanks for the sub! Feel free to add your suggestions for future episodes. I built the chamber for you guys.
Is it just me or did the modded watch minute hand stop at 20 meters? It never moved from that time on which is a giant failure right off the bat. The case survived but you lost analog time function at 20 meters.
Awesome stuff
That was really cool to see.
Wet suits are closed cell foam and should decrease in thickness at depth, and decrease in insulating value as well. I wonder at what depth they reach their minimum thickness?
7:03 u got me messed up using headphones
the carbon core case definitely does it job
But Why minute hand in mod watch didn't move at all even before pressure?
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
I would argue that both watches actually only made it to 400m because that is when they stopped functioning.
I want to replicate this mod. How did you do it?
I need to oil my watch. I don't need it, but i WANT it 😂
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.
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!
make sure its a solar powered version
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.
I have the exact same gshock. time to go do this. Great video! you got a new sub!
Me too. Cool watch, wish the lume was better though.
that headphone warning really helped haha
I'm gonna have to investigate this as a method for preventing glint for tactical applications.
