The problem is that mechanical watches are unnecessary as a whole. So arguing that a HE valve is unnecessary is like saying "duh I have time on my phone". It's about what a watch can do and how it makes you feel, not about what you need.

[@JustBlueFish]

There’s a difference between unnecessary and useless, at least to me.

[@lucioledizerot196]

@@JustBlueFish fair point. At the end of the day it's a very subjective matter. What might be useless objectively might be useful subjectively.

[@TankEsq]

I have to say I find a mechanical dive watch way more practical than any of my quartz watches. My SKX after regulation has been chugging along accurately for 6 years, I don't have to worry about it running out of batteries. I don't have to worry the battery acid will destroy the watches I don't use and forget about. I also hate the annoying ticking of quartz watches. It's also more reliable and robust in an apocalypse.

[@lucioledizerot196]

@@TankEsq I'm sorry but that's just not true. A mechanical watch will never be more accurate or reliable than a quartz watch. As for your personal preference that's totally understandable of course.

[@TankEsq]

@@lucioledizerot196 I'm sorry but it is true. I don't need a watch to be hyper-accurate. +/- 5 seconds a day is plenty good enough. ISO certification makes it shock resistant, water resistant, everything I need. With a big watch collection I can't be bothered to constantly be changing batteries.

[@malikknows3510]

My $.02 on water resistance. Had an IWC chronograph, mecha quartz I wore on two tours in Iraq. I was doing a lot of helo insertions and it was a very dirty, dusty place. Sent the watch to IWC for service and they were apoplectic about how I'd treated the watch. It has a screw down crown and two pushers. I believe the water resistance is 50m. The watch never went near water, but was in an environment where dust and dirt were able to intrude into the case. This tells me the water resistance rating is not solely useful for water, but also for dirt and dust. To be safe, and probably an over reaction, I now try to get as much water resistance as I can get. That's why I like Sinn as most of their watches, even the aviator watches, are 200m.

[@ref6122]

I consider the dive watch as a rugged ,water resistant , outdoor timer watch. The idea that it can also be used for diving just adds to the mystique and appeal.

I am going to break the mold a little bit in 1978 as a teenager in South Florida i got my first Scuba Certification and i needed a Dive watch as part of my equipment i called my God Mother who was working at no other thanks Seiko Corporate as a Human Resources person and got a pretty decent discount on all their watches so i asked how much she could get me the Seiko dive watch for she called me back a couple of days later and told me that the best deal she could get was a Pulsar divers watch that was essentially a rebranded Seiko in one of the Companies other divisions i did order that watch and it has performed flawlessly on over 250 logged Scuba Dives the original battery even lasted 14 years in that watch oddly enough the replacement only lasted 1 year and my biggest beef about the watch has been the Black Rubber watch Band that is essentially a Seiko Branded band and is overly priced and hard to locate at nearly 40.00 per band and they just dont last very long IMO yet as a Watch i have no complaints as my “Old Faithful” has kept me safe on al my dives over the years and although i have other watches and some moe Dress quality i prefer to wear my Dive watch even when wearing a tuxedo for a formal affair

[@JustBlueFish]

Great story thanks!

[@podratic]

Craig Monteforte you’re not going get the “thumbs up” for a Pulsar review with a quartz movement, no matter how well it performs. The watch community is much like the art community. They have their gatekeepers who protect their offspring from any perceived attack. It’s the hype machine.

[@petes5152]

Your point about ISO ratings is right on and why one should always buy an ISO 6425 watch if they intend to dive. Each individual watch is tested not just a selection of that model. Great points and a great video. I've been diving for over 20 years and have gone through my fair share of watches. I've never used a helium escape valve, I've never needed any depth rating over 300 meters even tech diving, and I've never had a crown leak. To add one point though, MAINTENANCE is important if you're diving. My non-dive watches go 10+ years between services. I've had one watch since I was in high school (20+ years) and it's never been serviced, still ticking. A dive watch though, service every 3-5 years depending on use. Heavily used, more frequent service. If something is going to fail, it's going to fail under pressure and that's usually when you really need it to work.

[@chi-towncalifornia5916]

Why are dive watches so popular? 1. They're the choice of many movie characters like James Bond, who inspire a sense of action and danger. A dive watch seems more adventure inspiring than a dress watch. 2. They're overbuilt and overly capable to handle anything you could possibly throw at them. It's why people started buying SUVs. 3. Dive watches are incredibly legible and they have spinning bezels, which make for both great timing and fidgeting devices.

[@JustBlueFish]

On point, good explanation.

I did my scuba certification wearing a $47 Timex Expedition chronograph rated to 100m, and it had no issue with me swimming around at the bottom of a 90ft lake, and no issue when I did hours of hookah diving at 8-20ft for work. So I get confused when a 200m dive-style watch says it can't handle anything more than surface swimming.

[@JustBlueFish]

Ya I still don’t know.

[@handyman2183]

All of my watches are divers. Used to own a Daytona and sold it because it just was not “me.” I Like divers because they are durable, casual, easy to read and functional. Of course the helium escape valve is not necessary. I agree with others, the watch itself is unnecessary since I bet you that 99.999999% of those who own a watch with HEV do not need a watch at all. Mechanical watches to me are like works of art. The paintings in my house are completely unnecessary, but I own them because of how they make me feel. What percentage of exotic car owners will ever reach the limits of their cars? They own them because of what they are capable of doing not because they need the performance. Lastly, there is a direct correlation between water resistance rating and build “beefiness.” A watch capable of surviving in 5000 feet of water must be built more sturdily than one rated to 50.

I don’t believe that’s true, and outlined that in the video.

[@glennpowell3444]

@@JustBlueFish Its basic hydraulic theory. A seal is only as good in tolerance as the pressure applied to it at any moment. Water doesn't compress so even a tangible force against it creates huge back pressure relatively. Hydraulic rams suffer similar load failure if sudden out of tolerance forces are applied.The seals being the weakest link.

Hahaha. How true. I am a diver and I get it. Funny thing, however. Saturation divers - like any serious diver - will use watch-like computers, yes. That said, many saturation divers still enjoy wearing a capable watch while working at great depths just to keep a sense of time and connection to the surface. The question should there be valves on retail watch production is, “depends.” Maybe adding the valve should be optional. That said, 007 Rolex or Seawolf Blancpain appeal for a few minutes in the pool or shower is pretend play and the closest anyone will ever get to being an elegant secret agent. Let’s give all but the most arrogant customers permission to feel like, Bond, James Bond :)

[@PhantomObserver]

About water resistance: 1. Realistically, it’s about the warranty. Watchmakers will not repair / replace a 3ATM WR watch with significant water damage done while swimming. That said, people have taken Casio F91W watches into the pool and the ocean without incident despite its 3ATM rating. 2. The ISO 6425 rating lists the minimum WR rating for a dive watch as 10ATM, or 100m WR. This tends to surprise a lot of people who see dive watches usually rated at 20ATM. Also, the standard does *not* require a screw-down crown, only that the crown be resistant to shock or impact. 3. Watch enthusiasts have tended to make no distinction between 3ATM and 5ATM. This may be due to the broad interpretations of what, exactly, is meant by “casual swimming” which is what 5ATM is intended for while 3ATM is not. A professional water sports athlete, for example, may consider 5ATM is inadequate for her purposes while the casual tourist doing the backstroke in hotel pool may think 5ATM is just fine.

[@merlinzipp]

Also if you flood a $15.00 watch, it's not a big deal. A $200 or $2000+ watch is a different story.

[@desmondoreilly1210]

I love dive watches and used to do a lot of diving too. That aside, I think the design language is something of a classic. There is a lot of iconography attached to dive watches. Men in particular like to buy in to that. It's a bit like Marlboro cigarettes; macho cowboys did a lot for the brand; with a lot of smokers buying in to the strong imagery around that. So many people that own dive watches will never even get them wet, but they like the associated imagery and perceived sense of adventure.

Agree HEV is but a novelty. I don't even dive with a watch any more, nor do I know any other divers who do. Timekeeping is taken care of by our dive computers. And while there's something to be said about having a backup timekeeping device, a second computer makes much more sense as a redundant backup.

[@robertsullivan4773]

First when I got my Omega Seamaster 300SMP I looked up everything about the HEV. I even watched saturation diving video. Talk about scary stuff those divers are under water Astronauts. So I hear what you said. I still love my watch had it. I don't care that I will never use it and trust me mine is screwed down tight and isn't going anywhere. I just like the concept and it's history and the fun I have and will have explaining what it is and does to the handful of people that might ask about it. As to water resistance thanks I studied it to and am still just as confused as you. Screw down crowns I have four and they are a pain in the butt when you have to wind the watch but not bad if the watch is automatic and all daily wearer. Great vid.

If the discussion of this video is of superfluous watch features, then the scope of this video is far too small. The list of “useless” features for most users is myriad. Cough - the Rolex cyclops for ANYBODY with a driver’s license (i.e. corrected vision). And I’ve got multiple pre-SKX watches from Seiko that passed the 150m pressure test (75% of their rating) 25 years later with original seals. The Twinlock and Triplock mechanisms are indeed superfluous as well. Lastly, a screw down crown permits the precise application of torque-limited pressure onto a seal that can’t be applied with precision unless a precise geometric limiting function exists to prevent excess deformation of the seal (reducing WR and decreasing seal life). That’s a huge benefit. I’ll add that I have significantly greater confidence in Omega/Rolex/Tudor’s ability to effectively seal an extra aperture in a case over the seal/crystal/caseback geometry or thread precision of most other watch brands .... no matter how many holes in their case they do or do not have.

[@Foxtrot-jr5qu]

That's what i'm saying all the time - just because a watch has 200 or 300 meters of water resistance on it doesn't mean it's a real divers watch. I'm sure it will handle swimming or even basic diving, but i'd feel much safer with my Seiko Samurai STO while swimming than any of the Chinese brands that offer sapphire crystals and ceramic bezels with questionable 300 meters of water resist. The only non ISO dive watch that I trust is my Vostok Amphibia. I also agree that the helium valve is totally useless and while some might argue that mechanical watches are useless as well because quartz watches outperform them in every aspect possible, at least you can use your mechanical watch while the valve will never be used and i'm sure even a moon phase is more useful than the helium valve. Some might not agree but that's ok.

@@djzrobzombie2813 So what? The Vostok Amphibia which has 200m of water resistance and was tested at around 800m and nothing happened. Just because some watches can push far beyond their recommended water resistance it doesn't mean that all of them can. Every watch company makes their tests and puts those things the way they like but like I said just because some can do it it doesn't mean that every single watch from every other brand can. There are exceptions for almost everything in this world you know. I'm 100% sure that the watches who have failed such tests are far more but you won't hear that much about them unlike those who have succeeded. I've heard even stories about professional and expensive diver watches that got water inside of them from swimming no diving. so there's no 100% guarantee.

[@luisdelafuente]

One of the things I think watch connoisseurs know and appreciate is that watches were historically meant to be tools. So some practical use is expected. For most of us, dive watches have all the features we might ever need: you can take a shower with it, ot work in the yard with water and dust, they're sweat resistant and you can check the time in the dark. Other complications like GMT or perpetual calendars are generally less useful, because not all of us are global travelers or are willing to spend 15 minutes to set the date if the mechanical watch runs out of power.

I suspect the whole nonsense surrounding water resistance ratings you describe resulted from manufacturers over hyping the capabilities of their products, and then being called in on it, perhaps through claims for financial reimbursement or repair under warranty, and subsequently going through a “how can we wriggle out of this one” process. In particular I reckon it may have been one of the main players In the budget to mid range segment, who have a very large share of the market (I’m not going to say who because I don’t want to get sued, but I think you can guess . . .). This particular company suddenly came up with the whole “dynamic pressure” excuse as to why, for example, a 30M watch is only splash proof, and a 100M watch can’t be taken down to 100 meters!! That’s marketing I guess, & the result of manufacturers talking-up their products for competitive advantage 😁! As to the whole HeV issue, I couldn’t agree more with you. I’ve read that modern Viton gaskets render them obsolete even for saturation divers in any case. I love your videos btw, always informative, & very well prepared! Thanks.

Not sure good question.

[@petes5152]

Omega's HEV simply has a crown you can screw down to seal it off. The actual HEV is basically the same tech as what you see in a Rolex and is located behind the crown you see. The idea is that you seal off the HEV most of the time then unscrew the crown as you raise from depth thus exposing the valve to let it do it's thing. Extra safety measure to prevent water ingress.

[@AlexanderB.]

@@petes5152 Thanks for explaining. I think even if Omega insists on applying an HEV, a lot of watch collectors would be happy if they would release future versions without that crown, given how few owners of a Seamaster really use it for diving.

They are built to be robust enough not to need a helium escape valve, which pretty cool in any case. Additionally, the part about the screwdown crowns perpetrates another misconception. Water can enter a watch if the gasket sealing the watch rotates, screwdown crown prevents underwater rotation. It is a safety mechanism eliminating a particular failure mode.

[@JohnBuckmaster-sw3wm]

Thanks for the information! I wish we had a better standard for water resistance ratings...But we don’t. As an avid watch collector it drives me crazy, and I also think many manufactures play-off of the misconceptions of consumers. I decided years ago I was not going to buy a watch, that didn’t have at least a 50 meter water resistance rating. The only exceptions that I’ve made to that are a couple of ‘Chinese specials’ That otherwise have great specs and are dress watches. Field watches I want 100 m Water resistance, And let me explain why. Three or four years ago now I wore my Hamilton Field watch while white water rafting. 50 m of water resistance was the rating. It was submerged in no more than 5 feet of water and then only for less than a minute (max). It was full of water and ruined by the end of the day. Sport watches and field watches in my collection Have 100 m Because there’s too many choices out there that have it, so why not! I like a screwdown crown on any sport or field watch as well… That way you can’t simply knock it or accidentally leave the crown pulled out(In which case the water resistance rating is zero). I go diving on occasion(twice last year). I’ve never been below 140 feet and usually less than80-90. Maybe it’s being overly cautious but I don’t even wear my 200 meter watches that aren’t ISO certified when I do that. Why would I when I have several ISO certified watches?! I realise that that’s being overly cautious, But at least That way I am I’ll be guaranteed never to ruin one of my watches watch again!

[@bloodymarvelous4790]

Maybe someone can help me. I'm having trouble finding watches with certain complications that I know for a fact exist. - a high intensity laser - a circular saw - a grappling hook - an explosive timer I know they exist because I have seen videos of them, but none of the manufacturers I've researched seem to carry them.

[@MrDanijelho]

i buy watches with 100m water resistance or more just because i don't have to take them off when taking a shower or swimming( i never dive )

[@JustBlueFish]

If it won’t leak when I clean it it’s water resistant enough for me.

[@wristray8775]

Very wise. I think mechanical moonphase is not as useful as a quartz one. Same is true to an extent for chronographs.

[@malikshabazz7596]

I think watch enthusiast like drive watches more, as watch cases are metal, and most dive watches come with Bracelets that match the watch case, Bracelets are just more attractive to the many, all those Rolex watches come with Metal Bracelets, who has a Cellini and Bracelets last longer than straps.

[@seang2822]

The helium escape valve is a styling cue to differentiate the watch, similar to the rotating bezel for desk divers... an unnecessary item and cost

[@danielfrancis3660]

Here’s the thing, dive watches aren’t used for diving hence it doesn’t matter what features they have or don’t have. If you go diving get a $200 dive computer.

[@ADudeAndHisWatches]

Good one, thanks!

[@cowboyswami2017]

Totally agree with u. But IMO u missed one, difference between water resistant and waterproof. Isnt the deep sea-sea dweller & omega(not in production though) the only companies that make a waterproof watch? Awesome video!

[@stephens2r338]

There has only been one watch made that you could call water proof and thats the one off Rolex DeepSea Special back in 1960. Thats because its not possibe to go deeper on Earth . It went to the deepest part of the ocean which is 39,000ft strapped to the outside of a submarine. The current version is rated to 12,800ft

[@ХристоМартунковграфЛозенски]

"Waterproof" was used decades ago and they dropped it a long time ago because no watch is "waterproof", there's always a risk of failure. "Waterproof" would mean that never ever could water penetrate the case, which obviously isn't the case (pardon the pun). So the only thing you'd get nowadays is a "water resistant" mark.

[@JustBlueFish]

I don’t think anyone can legally call a watch water proof. I might be wrong on that. But I think that term was no longer used for a long time.

[@Andrew.W75]

@@JustBlueFish I believe waterproof on watches was changed to water resist due to changes to the Truth In Advertising laws in the US in the late 1960s. Companies were given a period of time to comply & Seiko, for example, changed it's dive watches to water resist in 1970/71.

[@stephens2r338]

I agree with the notion that no watch is waterproof however the deep sea special Rolex makes me doubt that statement. It is water resistant to the highest pressure that exists on this planet. There are higher pressures on other planets but they dont contain water so by that definition it is water proof!

[@j.burgess4459]

Interesting comments regarding the helium escape valve. There's a lot of truth to what Guy says. However I have to agree with those who have pointed out that one could very easily extrapolate this kind of thinking to call into question the point of even owning a mechanical watch at all. Sure it's true that 99.999% of owners are never going to _need_ a helium escape valve. Hell, I can imagine that 99% of them are never even going to take the watch anywhere near the sea, much less go in a compression chamber, or whatever. But it is just the fundamental characteristic of a watch like a Sea-Dweller (for example) that it has the specification of a professional saturation diver's tool watch. You don't have to _need_ any of the features. It is about the watch's intrinsic character. It is about what the watch IS. Taking away the HE-valve from that Sea-Dweller would therefore be limiting and detracting from the watch. It would be making it that little bit less interesting and unusual. Moreover, if you are going to spec a Sea-Dweller based on what is realistically _needed_ by the vast majority of buyers, where exactly do you stop? Does it _need_ to be pressure resistant to 1220m? or would 200m? be more than enough? Okay, but then how is it in any meaningful sense still a "Sea-Dweller"...?

[@seang2822]

So we can swim with a 30 meter water resistant watch? If it is tested to iso6425

hearsay but a watchmaker once told me that if a watch passes the 50m in a water tank it will uphold to quite a bit more.

I’d believe it.

Valid points re HEV & saturation divers. They’re wearing indestructible $80 GShocks that are +/- 5 seconds a month.

[@stevek8829]

You're sure right about the helium valve. I love the wart on my Seamaster but I realize it's a poser. Not one person has ever piped in on a forum saying they're a saturation diver who used a Seamaster. Not even a liar! I wonder if you open it underwater? If so what if the external pressure is higher and water rushes in? How does our diver know if the watch is filled with helium yet, or to full pressure? What if she works outside the environment and has to ascend 100 ft? Should she open the valve? You are correct, it is just one more thing to make sure is tight before submerging the watch, one more hole in a water resistant container.

[@JustBlueFish]

Thanks for watching Steve!

[@danielmewes]

Never open it underwater. Only for the decompression phase, which is all dry in a chamber.

[@FourIntoOne]

The HEV. A small valve designed to make increased sales from the gullible. I have a relative who is a saturation diver from the late eighties till now - he and his colleagues wouldn't in their wildest dreams spend the sort of money on a Rolex or Omega to go saturation diving with, way to expensive for a tool, and as for using a mechanical watch - no way hose.

[@tynchytemper9618]

Apparently Saturation divers who use mechanical watches just pop the crown during decompression

[@mkyhou1160]

I don’t think anyone minds the HEV on a Rolex deep sea - it’s a cool functional element (even if its as useless for most people as a moon phase or a tourbillion). Omega have made their lower tech version part of the Seamaster look, I’m ok with that, gives James Bond another button. In practice you don’t really notice it if own the watch.

[@MTbone7]

Good vid, but these points would have meant more 20+ years ago when watches were still tools. Now watches are mens fashion accessories, and Omega's HEV is a marketing gimmick, screw down crowns just sound safer, and most people don't take a luxury watch in the water. Many just like what looks good, and based on the crazy Rolex market, what holds value.

[@itsalgud1459]

Well said! It’s about time that these various myths are the debunked. HEVs are functionally a total waste, but like a lot of these things, if someone likes them on their wrist, no big deal. I’ve been saying the same things about water resistance for years, having been an engineer and having designed and worked with thousands of different pumping and piping systems involving sealing off instruments and such. This whole “dynamic loads“ argument is total BS. Such a thing doesn’t exist except at very high velocities. I think the water resistance rating is far more dependent on the make of the watch. I would certainly trust the rating of any decent quality watch, and not believe any WR rating from the lakes of MVMT or DW. Thanks for clearing this up. I’m sure I will refer to this video Many times in the future when I run into people online making these ridiculous claims.

[@JustBlueFish]

Thanks man glad you liked it.

[@imranbecks]

The helium exchange valve is a detonator. Of course its important.

[@kennedymcgovern5413]

It is not about need. I used to own an SRT Challenger that would do 176 MPH. I had no plans to drive around at 176 MPH. The feeling just comes from knowing that it CAN. The same principle applies for most people and their big daddy dive watches. Hell, I'll go one further. I do not dive at all...I do not so much as snorkel. But I own a dive watch with a helium escape valve and... ...I almost never wear it because it is too damned big! Still, I like it sitting on my winder...just like I used to like knowing my Challenger COULD almost keep up on a NASCAR track. It's not supposed to make sense. If it were about making sense, we'd all buy hundred dollar, multi function, digital G-shocks and call it a day.

[@jimg518]

About the Helium valve: Like Spock said, “the needs of the many outweigh the needs of the few.” If this thing is something almost no one uses (99.9%) just make a few special editions with this valve for the very few saturation divers. Even though I love the Omega 300M I wont touch one with that valve sticking out. A know a lot of people who told me the same thing.

The protruding helium escape valve is an eye sore imho. Divers are not as appealing due to their thickness. Not an everyday watch like an Explorer 1 style.
