Check out my shorts to see the test done by holding it up in the air, pressurizing the tank and then lowering it into the water to look for bubbles. Future videos the test will be performed this way. Hopefully this still shows the ability of the watch regardless! Thanks everyone!
Finally, the whole story about water resistant watches. That took nearly 10 years of watching YT reviews to get to this comprehensive detailed video. Bravo..!!
Glad I could help!
Harrison just single handedly destroyed the diving watch market haha
The rotating bezels are cool though!
I use a Casio Dura not wasting 1000s on an expensive watch
@@wyldwiisel9126 That Duro will handle anything you throw at it.
😂😅 NOT a diver just an average snorkeler & pool commando. I’m a Casio fanboy 😂
I took an F91W on my PADI Advanced course and went down to 100ft. It was absolutely fine.
I’ve been telling this to the dive watch and watch community in general for years and the topic has almost always become heated. Thank you for your video.
Appreciate it!
It’s revealing and depressing at the same time. In reality all we need is a $12 watch unless we are going to the Operatic theatre.
waech is a toy for making yourself happy
Unfortunately yes
Agreed, it is a little depressing. I have 7 watches totalling a few thousand bucks and the truth is I wear my Casio more often than any other. It's worth noting it's not just any $12 watch, it's a Casio.
Nah. I wouldn't want to wear a piece on plastic strapped directly to my skin every day. That can't be good, can it?
@@kresimirpleic still, drinking and eating from plastic must be much safer
Finally, a comprehensive answer to the "maybe you can wash your hands with a modern 30m water resistant watch" people.
I swim with my speedy all the time.
One specific thing you did not mention about ISO 6425 is that this standard requires every single watch that is being produced, to be pressure tested up to the rated depth + 25% and remain at that pressure for 2 hours. After that test, a condensation test must be performed to check for water ingress.
This means that if you buy a watch that has "DIVERS 200 m" on the dial, that that very watch has been at a pressure equivalent to the rated depth + 25%.
I am glad that you debunked the myths about water resistance.
Very good point! You are correct!
Plus other durability tests.
@@folksurvival No. All other tests mentioned in ISO6425 are so called type tests, meaning these are only performed on a newly developed watch when it goes into production. Only the waterproofing and condensation tests are performed on each and every watch.
Very interesting! I’ve never even considered any watch less than 200m and I don’t even dive anymore 😂
I think the minimal water resistance rating on the basic Casios is partly because you're not supposed to operate the buttons under water. But I believe you can do so on the basic G-Shock square DW5600. That's a $50 watch that does almost everything, and you can drag it through hell. On the low end, I prefer the F105 to the F91 because of the EL backlight, which is like Timex Indiglo. Similarly, in stainless (with a metal plated resin case), I like the A168 better than the A158 for the same reason. Overall, it's incredible how good these are for the money.
I wear my F91w during my swim work outs in the pool.
I swim 1,5 km twice a week, doing all kind of strokes, freestyle, butterfly, back stroke, breast stroke... no problem! Works perfectly fine! 👌😊
It really must be the best watch for the price and with a cool history to go with it! Can't go wrong!
Great video! Thanks for clarifying!
Awesome to hear!
I don't think you're using the machine correctly.
Your meant to pressurize with the watch above the water level. Let it sit. Then lower into the water. Then slowly release the pressure and watch to see if bubbles are released from the watch.
I’ll make a short doing the same test this way. Good callout. Clearly it still should work, but we’ll see. Took too much time researching ISO certs and not enough on the machine
Why is that the methodology?
My guess is one might assume it’s more realistic because on a dive you’d start in air then go to water. But in this tank isn’t the air at the same pressure as the water, which is of course unlike real life?
Am I misunderstanding something?
@@rbalfanz since air molecules are smaller than water molecules, if it's airtight, then it's definitely water tight. The correct method allows you to check the seals without risking water getting into the watch.
@@jeebusmcfries8114 Exactly. Airtight is as good as water tight and if a seal has failed you didn't fill the watch with water. You'll see where the bubbles come out and know where the problem is.
@@rbalfanz as others have said, it's not meant to be a destructive test if possible.
The other aspect, it's hard to observe water intrusion. But a bubble stream is easier to observe.
A small step for the F91W - a huge leap for GodTier watch lovers
Nico would B proud mate 😊
Thank you. It’s about time someone did this. Liked and subbed. 🙏
Super fun video! Thanks for all the useful information. Love your content.
First time seeing one of your videos! Really well done! Great work
I think it was 1971 when watch makers had to stop calling their watches waterproof and instead say water resistant. You will often find vintage watches from the early 70's where the case back will say water resistant but the dial will say say waterproof. This is because the dial was made before the date of the change. Most diver type watches will state the minimum water resistance and rarely the maximum. The Vostok Amphibia has a 200m water resistant rating but has achieved twice that. 👍
I used a Vostok komandirskie for daily and it also had 200m water resistance
800 metres before it stops working and 1200 metres before it implodes and leaks water 😁
@@andrewallen9993 The Vostok Amphibia was designed for the soviet military.
@@orvillefindley8117 So the designers and manufacturers would have received a long holiday in a Siberian salt mine if the watches WEREN'T as waterproof as stated 😁
@@andrewallen9993 It was actually Stalin who started the Soviet watch making industry immediately after WWll. It came about when a lot of soldiers returned with watches that were given to them by Western forces. The original Amphibia was not available to the general public and could only be purchased by soldiers at designated military shops. I have a very nice Vostok Amphibia and a Komanderskie with the KGB dial. 👍
Seriously excellent content. Bizarre that it's so hard to find this kind of content online, you're unique in this field. Thanks for making this video!
By far the most interesting video in any RUclips watch channel in ages
Glad to hear it!
Nice video. Thanks.
This was great! Thanks for clearing up about water resistance tolerance for us layman. I've been collecting watches for a long time but just took for granted that 30 meters meant it was good for getting it just a bit wet. I have many watches from that same Casio to Rolex Sub and now I know I don't have to worry too much about water tolerance.
Very interesting and useful video; thanks for taking the time to make it!👍
Best WR video to date. Thanks.
Great video! Super informative - thanks.
funny thing is that I used to snorkel-dive with a swatch all thru the 1980's to depths of about 15 feet. This is what most recreational watches go thru. I never had a leak. Fast-forward to recent times and manufacturers tell usthat the same "30M" rating is only good for "splashing". Shows that these companies lowered standards to what they wanted to, to achieve cost-savings and reduce liability. As a side note, the author of this video is quoting the "new" ISO rating that came out 12 years ago and is optional (ISO22810). Most companies still use the older 30-100-200 ratings that had the "splash"/"Swim"/Dive levels.
Buy a Russian Vostok Amphibia. Those are really waterproof unless you dive to depths that would kill you in which case you won't need a watch.
Very informative! Thank You!
Anytime!
Love the content 👍🏼
Thank you for explaining 😂 I’m a fan now
Very informative video! Thank you!
Fantastic video! Subscribed
Awesome, thank you!
Thank you for this. This is excellent content!
Glad you enjoy it!
Very nice video, Harrison! I like that you have experience as a diver and shared what it’s really like down there. Most of us have no real understanding.
For me, I just want to be reasonably assured that my watch won’t be destroyed when being outside in the rain, swimming, and cleaning it occasionally. I’m thinking “50m” would assure all these things.
Thank you. These WR myths need to end. Too many people are missing out on great watches because they are under 100m WR.
Agreed!
I’ve a small watch collection of maybe a dozen. In 2020, I bought a F91 for sometimes sports wear. Always love it. Not that it really matters, it now has a nylon strap and my old casio A700 module inside. In Feb 2024, it accidentally went through a full wash /dry laundry cycle. No issues or damage. Recently opened the back, dry as a bone. Thats enough water resistance for me.
Thanks for dispelling all the misunderstandings about diving depths and pressures, etc
You bet!
Great coverage on water resistance
Finally, someone said it and back it with hard facts. You Sir, have earned my subscription.
Thanks!
This video is phenomenal
Great video , as usual 😉
Amazing watch 😍 thanks for the video
Thanks for watching!
Awesome video! I believe you have to pump up the pressure while the watch is above water for the air to get in the case, than submerge and release the pressure above to see if the high pressured air (should it have got in the case) now escape to equalise the pressure.
Yep, that's how you should test...
Isn’t that only to avoid water ingress, in case of an expensive watch? This way is more realistic
@@wonderwatch2239 You are pressurising the air above the water, the air will only get in if the seals are compromised. When you suddenly drop the pressure the pressurised air will escape. You drop it in the water to see those bubbles escape. The water serves as an indicator to see the bubbles and not to provide the pressure.
I think that's just for checking for air leaks in empty watch cases for automatic watches.
@@wonderwatch2239 air molecules are smaller than water molecules. if it's airtight, it's definitely water tight
Awesome test.
Ty for busting myth. The other day someone on Reddit was just arguing with me Tissot gentleman with 100 wr isn’t good enough for diving which is just ludicrous.
Thanks for the video. I have one of these Casio watches, along with a number of diver's watches. I consider it the 'coolest' watch in the connection. 👍
Maybe other comments have covered this, but in case anyone is thinking of using one of these pressure testing chambers with their watch, this isn't the way to use them.
I realise that for this video the watch is cheap and can be replaced easily. But the way to use this device is to hang the watch in the air space above the water, then increase the pressure. If the watch isn't sealed properly or the gasket needs replacing, only air will enter the watch. Then you release the pressure and lower the watch into the water at the same time. The air at higher pressure inside the watch then starts to escape, and you will see bubbles coming out of it where the seal is compromised.
This means that the watch could be re-sealed or repaired but no water got in to ruin the movement inside. Even very expensive watches can require a new gasket at times, especially after battery replacement or servicing. It would be an expensive mistake to allow water to get into the watch.
Thanks again for the video.
The only reason I spent $20 on my plastic Casio digital watch is that it has a much bigger font than the F91W, so I can read it at a glance even with my aging eyes. I swim in it in salt water (rinse it later), I wear it in a pouring rain, and in any other inclement weather that Florida can throw at me. Zero problems. I would never spend thousands of dollars on a beater watch. That's insane. Dress watch might be different, but beater watch? No.
Which casio model do u have?
@@ex0ticx0x AE1500WH-5AV.
quite informative. thank you. i knew that some of the watch reviewers did not know what the actual water resistance is on the actual diver watches. shameful, so thanks again for the info.
Very well explained, I don't think most people understand how deep 100 meters is. 99% of the time is someone's watch is deeper than 20 feet it's because it fell off of their wrist. This might be a big ask but can you do the pressure test on a Casio "Duro" MDV106? That's probably the most affordable dive watch on the market. Casio claims a 200m WR with this watch, it would just be nice to know. Thanks!!!
Brilliant. Thanks.
A Casio F91W actually has a reputation for being used under water. I’d like to see this test done with a Timex Easy Reader or Marlin or an Orient Bambino, some watch that *doesn’t* have that reputation for toughness.
My father in law wears his Orient Bambino while swimming (weekly for the last three or four years). It's not scuba diving but no problems with the watch so far.
😂😂 you can’t imagine how many times I hear “but bruh your watch isn’t 200 meter iso certified” it got to the point were I just say and nether are you
Loved this video. My 2011 Breitling Aeromarine SuperOcean is rated at 2000M...or 6600ft...with an automatic helium escape valve. It does just fine.
A bit excessive no? Its not like you've ever going to go that deep haha
Fantastic video
Thank you! You've made a video on one of the biggest misunderstandings in the watch world. I recently got in a minor argument with a person who was interested in a Hamilton Field Watch, but was worried that the 50m water resistance wouldn't hold up to daily wear and occasionally getting wet. A 50m Field watch will be able to withstand more water than most people will ever encounter. I really appreciate this video. I've also noticed that a whole lot of "dive"" watches don't include the word "diver's" on the dial.
great video subscribed! im going to order that 200m casio now lol
LA montre!!!! Une légende!!! merci!
If I’m at the river or in water I take the Casio I like the protreck line a lot! I have a few but my ole PRG-240 is my go to. Remember to replace your o-rings every ten years!
This was great!
Thank you! I have argued with so many of my watch friends about this. They always say 30 meters is not really water resistant and I always tell them yes it is! It drives me crazy. Just a side note, you’re supposed to pump the pressure in when the watch is above the water then lower it down into the water and then release the pressure. That’s how to use these. The watch still would have been fine but just wanted to throw that out there.
Outstanding demonstration and explanation, dude! Ignore all the negative Nancy comments because everyone is an "expert" on RUclips. Looking forward to seeing more content.
Such a great explanation and demonstration. This just proves how well made Casio watches are for absolutely no money. I hope people understand that it's not any cheap watch, it's a Casio. If you did this test on a generic cheap watch it wouldn't have the same reault.
Yup I’m surprised he didn’t mention this
Casio watches are over engineered I don’t think fashion watches with 30m wr can do this
I own one. Been swimming with it in the UK cold ass sea every day for years. Still works to this day
Great content mate, cheers.
Much appreciated
I enjoyed watching this. I remember Michael Schumacher had one on his F1 steering wheel to time his laps.
From experience with these Casio’s, my favorite included F-108 as long as the case isn’t broke if water got in. Taking the module out and giving it an alcohol bath, making sure everything is cleaned and dried, it’ll still work.
I had one for a few years. I swam with it for ages and it never faltered.
Curious if you would ever test a Freestyle watch (we had them in the early 90s in Florida everywhere). Supposedly built for the water.
Hey thanks for doing this test. The technical information was fascinating 👍
My father has his PADI Open Water certificate. He refused to drive with any watch that had buttons, he said it was too easy to bump a button and destroy the seal.
Could you possibly test some Skmei watches ? They're a very cheap Chinese brand doing Casio and Timex ripoffs....
PS : You might like to boost your lighting a bit, you're a little dark ...
The cave diver Sheck Exley used to wear Casios on all his dives. I'm not sure if they were f91w's or not, but they were cheap digital Casios. He'd wear two on his wrist and also wrap them around the regs of his staged decompression tanks as backups, but he never had one fail even in extreme technical diving beyond 200m. I dive with a duro or an ISO diver just for easy readability, but I'd have no reservations about diving with an f91w either.
You did not read the direction that came with the machine? With the watch OUT of the water, bring the air pressure up to 3 atmosperes. Wait a minute or two then lower the watch into the water. Release the air pressure and observe if any bubbles come out of the watch.
I am guessing this means that the test he has done is worthless?
@SirGwl pretty much useless by waterproof watch standards used by watchmakers all over the world.
The additional margin you need is in case you strike your watch against a hard surface (scuba tank, rocks, etc). An engineering margin of safety is usually double the max static pressure something might be exposed to. Underwater is a pretty harsh environment and the testing is under idyllic conditions (static temperatures, clean water) so I’d expect the spec to be more conservative.
so many cool aspect of this video, but remember without light source, you do not want to be pushing any built in light button on casio. And oil filling them will probably make them last to the abyssal zone. I think I've seen a 2100 g shock oil filled to be able to do that on youtube.
Great advice for non divers.
I am a highly experienced diver, and trained to a very high level by world class professionals.
I use housings on the surface and at depth, and the seals are at greatest risk of leaking when at the surface and dunking the housing in a freshwater rinse tank (not recommended). This is because the seals are not under pressure and so are at their least resistant to working. That is why the standards are different for splash and depth.
When diving, I may have a dive computer on each wrist of different brands, one of which is wirelessly connected to a tank pressure meter, and a third dive computer physically connected to the tank. All of this is to not get caught out by equipment failure in the wild.
In other words, when I dive I have no space to wear a dive watch, so in a watch for me splash resistance is way more important than depth.
Very interesting.
Great video could you try this with the timex weekender? im curious if they can hold up to the stated rating
Excellent video but it does depend on manufacturers reliably stating the actual ratings of their watches.
I have a pressure tester thats air only, and this watch has been my go to as calibration unit. If it passes i then i test the watch im working on. By the way, my casio is one of the original ones from the eighties and it still performs flawlessly. Go casio
Would like another video on how watches that are supposively water resistant get moisture trace on dial. Saw some of these on older Speedmaster and others.
Great video. Cheers.
Thanks 👍
That test just destroyed all of the Rolex fan boys!🤣🤣🤣
Great video! The experiment is very interesting. Can you try it with a mechanical watch that does not have a screw down crown?
I certainly wouldn't do it my Hamilton Khaki King with only 50M water resistance it doesn't have a screw down crown but I think the earlier Hamilton Khaki field watches did because they had 100M water resistance.
I just bought one of this as at 09-06-2024 and some clear silicone oil 6 centistokes to do the extreme water depth pressure resistant test modification, maybe you should do an update vid?
Have you ever tested the Hamilton khaki field mechanical? Says 50m but I’ve always assumed it’s more than suitable for swimming. Happy to send you mine to test!
Sir, can you rinse & repeat this using the same watch until the gaskets give up?
Thank you in advance from a spend resistant watch collector.
You should put the Omega Speedmaster in that pressure chamber to see what it can really handle.
Yours first! The bubble test would be what you want to do: (1) 60m of air pressure, then (2) dunk it, then (3) release the pressure.
The F91w generally fails at 200m as the acrylic caves in.
Good to know. 🙄
Yeah…. I think humans die first before the watch does 😂
@@jpdemer5 This same channel has a video entitled "$30 Casio = 600ft Under Water?!" showing an A158 failing at 200m.
A friend found a similar Casio among the rocks shore submerged for who knows how long, he cleaned it and it works perfectly.
one word
GOD TIER!
It is the quality I am concerned about. A Hamilton Khaki Field claims 50 meters water resistance. But, will it really do it ? The F-91W just proved its Legendary status. I look forward to your other tests.
Would this hold true of automatic watches from companies such as Seiko who at 3Bar WR actually state not to swim with it?
Yes. That is exactly what the ISO 22810 standard is all about. If you state 30 m, it should handle 30 m at least.
At 18m there certainly can be current, great video, do your advanced, it will open up a whole new world...
I just stumbled across the h20 kalmar 2 Deep Diver. It’s rated at 25,000 meters. Can you test that next please? I’m interested in exploring the bottom of the ocean and I need a watch I can depend on.
You’re not using the instrument correctly. You must pressurize the vessel while the watch is above the water. Once pressurized then you lower it into the water. This prevents water from entering the watch if its not water resistant. When you slowly release the pressure bubbles will start coming out of the watch if its not water resistant. At this point lift the watch out of the water and no harm will be done.
Question: if air escapes the watch, isn’t it being replaced by water?
Also, is the test in the video a complete bust that negates the conclusion? (lol. Physics is tough for me!)
Bergeon SA has an instructional video on their RUclips channel. I've seen more than one RUclipsr do it wrong.
@@geoffreydlin8043 The air in the watch is not replaced by water. As soon as you see bubbles coming out, you lift it out of the water. I'd say the video is a bust.
I think I figured it out. When the watch is pressurized through the air, if air squeezes into the case, when it’s immersed into the water and pressure is released, the water is just there to see the air escaping in the form of bubbles.… Right? The water doesn’t do anything except help visualize what’s going on.
@@geoffreydlin8043 Correct! I suppose if you don't lift the watch out of the water in time after depressurizing then you risk water entering the watch.
very good and usefull!
Glad it was helpful!
Harrison, can you please share a link to your water pressure testing device?
Great insights. Any idea how long before those ratings diminish due to aging gaskets? 10 years, 20 years, etc..
Depends on the silicone used and the gasket quality. Also if you swim in salt water they degrade faster.
Just buy another one 😂
Watch is a device to measure time . At some point it became jewlery.
But....but....but it looks really cool and makes me feel special when it says "200" on the dial!
Great video. There are so many watch influencers on RUclips that need to watch this video
Thanks. I always thought that "WR" on a Casio really meant Resist Water.
Good video, and accurate for still water, but you should hear in mind that in the sea the force of a wave can exceed 30m static head. Unfortunately I learned this the hard way. You are actually more likely to ruin a watch playing in the surf than diving at depth.
People have taken these and i think the a168 or similar to several hunder meters of depth and the survived until the pressure bent the plastic screen so much, the screen broke the module by pressing on it. It never leaked though..
