The remaining air inside the watch is actually being pushed upward so hard that it was strong enough to break the glass. Filling the inside with oil basically means that there will be no air left inside. No air, no air pressure. Simple as that.

I have a question: I understand why the case ( and the back plate and crystal) survived in the hydro-mod, since the pressure won't change the volume inside the case and it won't deform as much, thus getting better resilience against pressure and holding shape better; but I imagine the buttons, the crystal and case-back still exerted pressure to the insides in the hydro-mod compared to the regular one. So I don't really know why the screen cracked on the regular one and not in the hydro-mod. Maybe it was case deformation and not air pressure that destroyed the LCD? That's my current Hypothesis. What do you guys think about it? Edit: After re watching the video yes, it's very obvious that what killed the movement was the deformation of the case-back pressing against the movement, It is very noticeable how the whole dial bent under the pressure of the case-back against the movement. I love it that is at exactly 20 bar that you start noticing the dial bending (and the minute hand stopping), the people at casio engineered the case-back so it withstands 20 bar and just that. but it didn't start damaging the screen up until 60-70 bar, so I guess if you decompress ( and maybe bend the case-back to original shape if needed) maybe the watch survives! I'm also glad I read the comments since I was about to do this to a similar casio watch of mine, but reading the comments I found a comment by the author that this mod indeed kinda killed the analog part of the watch.

And yet these "watch review" youtube channels continue to insist that you can't shower or swim in a watch rated any less than 50 BAR.

That watch could actually be rated to dive to the titanic. I imagine one specific person would be very jealous of that fact. It makes perfect sense, but it just feels like it shouldn't work. Same way that you can put solid state electronics in an oil bath, old substation transformers too.

definetly going to wear that watch when im going snorkeling the titanic :D just need a submarine that's going to pop me out down there.

I would love to see a Harbor Freight version of the pelican case since they’re significantly cheaper

Obnoxious music. :/

wow

You did not plug the pressure equalization holes?!?!?

china balls failing first, japan ball failing last... yeah that checks out.

Hydro modding is cool, but I feel like it’s more about customizing and personal engineering feats. I know a professional diver and he told me that a standard 100m dive watch is all he and everyone he works with uses. Even if you only get 30m of actual water resistance, that’s more than enough for 99% of his dives. My point is don’t worry too much about doing this if you want to take a watch diving.

Could be more quiet also

Did the minutes hand resume movement on the hydro watch after it was depressurized?

I sincerely hope Stockton has done this to his watch🤔

if i ever plan on skin diving down to the titanic ill be sure to grab a hydromodded watch so my kids can use it after i die.

Casio and G-Shock still being the absolute kings.

a side effect might be sensitivity to temperature changes since the oil have a great thermal expansion coeficient... try freezing and heating to 50ºC a few times... ;)

I think the "smoke" was whatever anti stick powder they used between the outer hull and the rubber bladder inside the ball

I did not expect the cork to give in violently

Something to consider: can you please test the Pelican 1650 and the equivalent Nanuk cases?

Another great video with his wicked sense of humor! 👍🏼

You know you can just lower the volume when a harsh sound is playing right? The warning 1s before does nothing for it.

I wonder if you could test prop cavitation in regards to increasing pressure. Maybe a prop working fine at two feet is horrendous at 2000 feet or vice versa. You might get some amazing slow motion shots. I suppose a lithium battery in an enclosure would also be subjected to the same conditions.

It would be good to see these oil filled.

Only reason to have a watch that survives these kinds of depths is so who ever recovers your body gets a free watch for their troubles. I say that as a diver of 30 years.

Very interesting! It is cool to see that all three exceeded their rating of 1M. I know you are well versed in many things and surely already know this... but I hope you washed the electrolyte chemicals out of your pressure chamber. That is delicious and healthy for us; but it is very corrosive to most metals.

If you like Canadian Dry, you'd love a Kentucky ale called Ale8. I highly recommend giving it a try.

The guy on the beach with the guitar? You know he's ditching the practice instrument for the chick! Beach sand is bad for bitches and guitars. Get the girl to the shower and the bed. He has his perfect priorities.

That into gives me anxiety

I am terrified of the ocean. I have no interest in watches. But I still watched this to it's depths for absolutely no reason other than entertainment. This is what I am become, a screen junkie.

You could try nail g*n blanks. It could be spectacular, but need to do the Math first. If we take .22lr as a reference, it's rated 24,000 psi. If I'm not mistaken, this is a max pressure inside the cartridge, if we take into account difference between internal surface area of the cartridge and internal surface area of the chamber, may it handle the potential cartridge set off?

Thanks for the test!

It’s got what cases crave.

Your note about mechanicals makes me wonder if it's possible to design a mechanical watch to account for the oil's effect on the mechanism. I imagine it'd be a doable, if difficult design to get right.

Could you model a caisson bends accident in which the water and air mixture is compressed and held at pressure for time, then the pressure is suddenly released showing gas bubbles coming out of the water like bubbles in the blood of caisson divers and scuba divers which causes the bends?

I love my Pelican cases. Thanks for explaining how the valve works. It’s a Gortex membrane, not a mechanical valve, so it cannot be used for diving.

My dumbass thought I would be seeing a watch being dropped deep into the ocean, I forgot equipment like this exists 😭

🙏 do you use a handpump ? Cheers 🍻

Great Documentary, you can also see it happening live! 😂👍🥲😝🤡

22:34 so is the Chinese brand lgbtqrstuvwxz++?

I like the commitment to adding blue plus signs to the Amazon prime tape.

Is this a poorly thought-out hype? Is it a bad idea to fill your watch with silicone oil? The oil has good di-electric properties, meaning that it is an excellent current insulator. And in your watch there is a 1.5-3V battery that is now surrounded by silicone oil. Silicone oil will settle between the contact surfaces for the battery. The result...very poor contact? I'm just asking: is this a good idea?

The 'bar' pressure is wrong on the scale. Sealevel is 1 bar, 10 meters deep is 2 bar, 20 meters is 3 bar and so on........

I would absolutely love you to test a G-Shock Frogman to see how deep it would survive. I wish I had one to spare 😀. Casio tested a GWF-1000 to 1000m and it survived.

Can you make liquid carbon dioxide and fill a pelican case with that

Try Rolex DeepSea

Any pelican with the clear latch stress fractures after a few months use.

Happy to be the 1% loyal Canuck follower. To be fair the Pelican had a better rating, so I expected it to do well. I think the real place the Nanak would shine is the impact resistance as you mentioned. I’d like to see two similarly spec’s cases (vs perhaps even include a Princess Auto version for Canadian fun). Anyway, a big hello you hoser from Vancouver!

Jeff, I have seven pressure-sealed wine bottles including a Freixenet Deeper Diver and a Kripta amphora. Add a 50μ 400 psi crush glass microbubble, epoxy syntactic foam ball, d=0.44 g/cm^3. Let's do a crush-fest! I need an address for shipping. My treat, our adventure. *HOW DO I CONTACT YOU?*

I don't really like that pelican latch though since I've seen them crack and pop open under impact in my own use.
