- How deep can you really dive with a soviet Vostok Amfibia dive watch from Amazon? How about oil filled quartz watch send by our viewer? We are going to use our deep sea / pressure chamber and test two diver's watch for their maximum depth / pressure! Our deep sea chamber goes all the way to 300 bars that equals 3 kilometers or 2 miles of depth so we can simulate conditions on bottom of the ocean in this experiment.

If you want to get a real Vostok Amphibia dive watch. You can order one from my Amazon Affiliate link for cheap price of $88.32 amzn.to/3s3GSlD
It's the exactly same classic Vostok model seen on the video made by the official supplier of the Defense Department of the Soviet Union and modern Russian Army.
Was it really necessary to break it in order to tell that 1942 technology doesn't stand a chance against 2018 tech? It's like finding an original StG-44 Type I and running a it through a mud test against a modern Russian made AKM. Just makes no sense and doesn't feel right. You put a greatgrandfather against its greatgrandson. Young man wins, wooppty ddoo, whatta surrprisss-ah, jusstta lookka att diss.
But amazing equipment and HQ videos + funny accents, i see why it works! :)
@@timberwolfmountaineer873 Yeah, i agree. It all looked like a waste of time and a perfectly good watch broken for no reason at all. Just like those superspoiled UA-camrs who used to drown their 500$ drones in a pool of CocaCola to see "if it will still work". DUH, of course it won't. But views are always nice and comforting.
@@timberwolfmountaineer873 you know its fun to break stuff, but obviously anyone with 1 functioning braincell could have predicted the outcome. hollow lucite vs supermodern german polymer filled with oil? oh wow, tough bet!

This is if u want to troll the investigators so they cant determine your exact time of death.
@@robotube7361 at 3000m doubt there be any investigators
Sinn UX dive watches claim pressure resistances for the movement up to 5000M, with cases that are pressure resistant up to 12000M.
I have to admit, if I ever found myself 3000m under the ocean, I'm pretty sure my main concern wouldn't be, "Shit, I hope my watch is OK!" 😳😂
You'd already be dead.
Yeah, but at least you wouldn't have to worry about that.
You'd be dead way before you hit this depth 🤣
if you are in a special hard suit breathing pressurised breathing liquid like in James Cameron’s The Abyss then you will need your watch to time your dive or you will stay down too long and die coming back up
Depends on the watch. I mean, 3000 meters below with my Patek Phillippe, my watch would be my Nr 1 concern
800 Meters for an $80 Dive Watch rated for 200 meters is pretty good 💯🤘🏽

The slow propagation of the cracks in the Lucite plastic "crystal" was weirdly, and almost organically, beautiful.

I think Vostok needs to change its slogan to “It does what we say it does. And then some.”
Most Vostok owners know about the previous 700m Vostok Internet test 😆
I like the, "it promises what it delivers"
“In soviet mother Russia, the watch dive you”
more like "don't be dumb, the watch is much stronger than you."
Back in the 70's, while most diving watches used brute structural strength to counter the increased water pressure of deep diving, this Russian creation was famous for using the water pressure itself as a mechanism for sealing the watch the deeper you sank.
"most diving watches" had something rather similar to the Rolex twinlock system for their crown, which uses pressure buildup on the crown to compress a gasket. It's fun to repeat these stories about the one brand coming up with a great idea no one ever thought of, but it's rather an intuitive concept that would've been used by one of the really strong and growing brands of the time. I don't think there would've been as much brute force as people think.

@@mclovin583 the one that didn't fail is.
I've owned two Vostoks, one komandirskie and one amphibia, and they were both terrible. The bezel action was like grinding sand, lume plots fell out and wandered freely on the dial, and timekeeping is horrid. You're better off getting a good Casio or Seiko for the same price.
But we have nothing to compare it to. Every dive watch could have similar results.

They tested other divers in the past.
You have no idea how long I've wanted somebody to do this, I've not even watched the video yet but THANK YOU!!!
No Sovjet Engineer has been harmed after this test - as the watch didnt fail its specs😂

As a watch collector this was a great intersection of two of my favorite UA-cam subjects. Watches and things being crushed via hydraulic press by the Finnish
Vostok watch from test - this is new design of old model. Designed in Russia after 2007. Base model was created in USSR at 1967 by order of USSR Military Navy. First name is НВЧ-30 - (naruchniye vodolaznyye chasy) - handheld watch for deep diver and waterproof by 300 meter (approved in tryouts and have military quality control "5"). At 1975 one of modification was used in USSR space research program as base model for spacewalking (work outside ship).
I have exactly that Vostok watch and I love the thing, considering getting a new bezel but other than that, I love that it's not pretty and it just does what it promises. They make no claims about exotic materials or finishing and the claims they do make are more than backed up by real world tests. Love Vostok watches, really.
Well, if you like a steampunk look then I suggest to bath the bezel in hydrochloric acid - gets rid of the garish chrome and gives a nice antique look :) I love my amfibia with the blue/brown 331 dial.
@@jfichl Mine gets that look "naturally" over time (I didn't take a dive in acid).
I think looks pretty because of it's simple design.
I have the Baikal Bezel for my Scubadude.. it looks the dogs bollocks it's brilliant, designed by the Italian Vostok forum. It has a scale of decompression depths (should you ever need them) in a wonderful period 70s design found on a lot of Soviet tech.
Same here, "brutalist" watches that cock a snook at luxury brands, "rough and ready" but work well within their parameters, so many thick people simply don't 'get it'. I have eight. Nice also be dealing directly with the factory, having to learn cyrillic in the process to avoid the rip off prices these go for on Amazon and Ebay. Win win :-)
I’m a big Amphibia fanboy and I’ve waited a long time for this. I think it put on a great show. Innovative engineering back in the 1960s and still admirable in the 2010s. Brilliant design. Seeing the crystal deform like that was just great.
The oil filled watch was interesting, but it really isn’t a practical mod for a watch. Though the principle works so well. Thanks!

@@standingbadger , because it's custom built (oil filled). You can pretty much do that to most quartz watches, even the digital ones.

@@GuyNamedSean water resistance rating is for, I believe, 30 minutes. So maybe if it was 3km down for longer it might fail. But I wouldn't want to bet on that, that Pulsar did an amazing job.
Wonder if it is mineral oil think that might slow it
Probably used novec
@@thecheddaravenger4084 it was predictable
The reason why Pulsar is doing much better is because essentially the quartz movement is just so smaller and there is a lot of room around the casing before it can reach the movement, however Amphibia is an mechanical-automatic watch. It's fairly packed inside the case and the mechanical watch is way more sensitive compared to electronic movements. And that's the reason why we love Amphibia. You get a nice watch with some real achievements for a fraction of the price. If that isn't a steal I don't know what IS.
the real reason the pulsar did better is because it was modded and filled with oil
When the Vostok broke I almost cried…
That Pulsar just refuse to die

I like these tests! I actually plan to get a Vostok Amfibia and good to know it lives up to even more than the stated performance!
I have finished the video. I am proud of what Vostok have done :)
Thank you guys so much for these watch tests!
That pulsar was absolutely amazing.
lol that soviet watch presentation was fantastic
Thank you for all the work you put into these!
I have both a Vostok Amphibia and a Oil filled Casio. Nice to see the Vostok did so well for such an inexpensive watch.
Kiitos! Very interesting!
Failure point seems to be the caseback, it bent inwards pressing the movement forward against the crystal. The watch stopped running just when the second hand hub jammed into the center of the lucite crystal (The hub looked light red compared to the rest of the second hand when it contacted).
I think that the fracture pattern of the crystal indicates that it cracked from the inside out - the failing caseback pushed the watch innards into the lucite, cracking it. I think that the easy fix of making the caseback thicker would have had the watch happily ticking along much deeper. Nothing else in the design failed - no water ingress because of failing seals etc.
It was that, or the crystal flexing inwards. Or both.
Truly impressive. Interesting to see it fail in stages like that. Brilliant simple design
You can buy sapphire crystal after market watch back, maybe that would help.
It's all academic as those depths are insane.

Anni, nice Rocky reference there!
"Ok, we're going to see about that" would have been a nice response in the movie.
Thanks for making this, was looking forward to it since you announced having ordered a Vostok. I was curious to see how the caseback looked though. You should consider including a table or maybe even a ranking board at the end of every video. Something that would include the price, rated depth, quartz/mechanical, depths at first point of failure (movement stops/illegible) and point of catastrophic failure for every watch tested up to that point.
No bucket or anything just dumb the water in right on the floor. I love how care free you guys are
Wow, oil filling makes an amazing difference. Excellent video. Thank you for making it.

And... Kirov reportin' as says in RA ))
Awesome to actually see this test. I was thoroughly impressed with the performance of the oil filled quartz watch. May I suggest doing the same test with an oil filled digital watch? There are no moving parts in a digital watch module, it would be interesting to see how deep they can go before they fail.
Thanks for testing watches. I am a big watch buy and I love the real testing you are doing.
Also not bad for $39 Vostok
I got here searching for videos of Zlatoust watches, and I am not disappointed. Awesome video!
I love you two! I laughed when you called the Vostok Amphibian "The PEOPLE's favourite" and when Anni said "I must break you" like Ivan Drago, I almost spit out my orange crush!
You two are wonderful to watch, so informative and so entertaining at the same time.
Totally agree...
Their accents and subtle humor are absolutely fabulous!

Thank you very much for the test with the watch full of oil. This is your best video ever.

James Cameron really should have put on of these on the robotic arm of his submarine. Would have made a really cool sponsorship.
Actually, he did that, with Rolex watch.
@@robertsz5707 The Rolex website has a whole essay by James about how much he loves the Submariner, but it only shows pictures of him personally wearing the watch, even though the sub is in a lot of the pictures. So are you sure he put one ON it? I can barely remember watching the movie tbh. Lol

Hell yes! Love the HP channel and I love Vostok watches!
I love Vostok’s. I’ve had mine for a few months now and it’s great. I made a couple of videos on it too!
The Pulsar began to move slower, so it was affected by the pressure. So even if it continued to work, it may be interesting to see if it still works over time - being as accurate as before...
the only way to really affect a quartz watch's accuracy is to mess with the electronic components within, which are conveniently cushioned by a lot of oil. that, or temperature changes which affect the vibration of the quartz crystal.
ah okay I see what you mean now. The seconds hand looking like it's slow motion. Well as long as the rate that it moves is the same, the precision won't change I think
@@recht181 yes, but given that it slowed down, it may have introduced some pressure there may not have been completely released when the outside pressure were released...
@@recht181 but would be a good test for it - the conclusion that it just works is not good enough ;)

I am SO subbed to this channel.
I want to see someone pressure test the Vostok Komandirskie Classic. It's built almost just like the Amphibia, but is only rated to 30M or something. I bet it would go much deeper before failure.
The main limitation with the 30m Vostok is the lack of screw down crown.
@@edwardfletcher7790 it does have a screw down crown
@@thomaswright2030 Ohhhh ok, not the one I'm thinking of then.
Is it an Auto ?
@@edwardfletcher7790 No. Hand wind. I'm talking the $40 one. It has the screw down super wobbly crown and has the same back gasket type as the Amphibia. The Komandirskie K-65 Auto (the $80 to $100 one) is just an Amphibia with different dials I'm pretty sure. I have that one too and it's rated to 200M. I want to see how well the $40 / 30M rated / hand wind one does.
that pulsar really surprised me with the dept it reached.
and i also was surprised about the depth the vostok held up to with its acrylic window and especially for a fully mechanical watch.
i hope you make a few more of these videos with maybe some cheaper automatic watches ^^
as soon as I saw this available (on my phone) I checked it out
Great video. I saw some questions about oil filled watches. So I'll out myself as a watch nerd -
It's a reasonably common modification done at home by watch enthusiasts. You use very light weight silicone oil so the watch can run normally,. If you look closely at the second hand you'll see it is less "snappy" than a normal one. That's the resistance of the oil. The watch still keeps perfect time, ticking once a second, but the hand is damped. Quite apart from the depth resistance, it looks cool because refraction in the oil changes the viewing angle.
Many people like see a single tiny bubble as proof that the watch is oil-filled. It also allows a little expansion if the oil gets warm in the sun. If you don't want the bubble and you worry about heat expansion there is usually room for a bead of expanded polystyrene somewhere behind the dial. Filling the watch without bubbles is simply a matter of submerging it with the caseback removed.
The battery will run flat faster, and changing the battery can spill the oil. All part of the fun. Of course, you could use a solar powered watch :-)
Seeing the watch off gas was cool and would have been nice to watch in slow motion!
I wonder if Yuri Gagarin wore a Vostok watch on his first human spaceflight on the Vostok 1 spacecraft on April 12, 1961. Almost exactly 60 years ago.

Well, the 100m WR on the dial is without the hydromodding. The hydromodding being filling the watch up with mineral oil 😛
@@OriginalLoLRandom is there a reason this isn't the norm?
UA-cam sucks now, it’s hard to change batteries for one, also the watch that is filled with liquid needs special mechanisms on the case to account for thermal expansion of the liquid. Most of the hydromodded watch are just normal watch filled with mineral oil without any thermal expansion compensation on the case. Also the movement would also need to be special since the quartz crystal oscillator used in the watch are typically hermetically sealed in a metal enclosure filled with air. The crystal will get crushed at some point even if the rest of the watch won’t.
@@youtubeSuckssNow Several. Battery changes are a pain, and messy. You also need a very specific oil that doesn't mess up the lume.
There is Sinn UX that's factory made to be oil filled, and they guarantee 5km water resistance before deformation crushes the movement. The case water resistance is around 12km on that one.

I've always thought that filling a watch with oil was a bit of a myth seeing various people do it on UA-cam. Boy was I wrong that was incredible and me proven it to be true!
Sinn has several wrist watch models filled with oil. It helps counter the outside pressure and it improves the underwater visibility by having less refraction. So I've read as a Sinn is way out of my budget. Mods should give the same advantages.
@@josecelestino Indeed, but the trick is to fill your watch with the right grade of oil (drop me a message if you want the grade) and also you have to fill the watch such that there are no air gaps inside the watch which isn’t always easy to do. Done it on a cheap plastic Casio and tested it to double what it’s rated at no problem at all!
Yes, I've been aware of oil-filled watches -- but no video has ever shown the practical application like this!
I thank you so much for this wonderful informative video!!

Thank you! Vostok - is the best! Respect from Russia! Thank you for learning of our legendary Vostok watch. Many interesting technical solutions are used in this watch (if you are interested, see my review in Russian). Sometimes the quality is not the best. But it mostly refers to the build quality. For example, before using in water, it is sometimes necessary to check that the back cover is fully screwed on. At this price, there is no other fully manufactured watch with its glorious history and original designs on the world market!
