100 meters is safe to swim with all day 👍
Mr Bond - his usual enthusiastic self...
😂
Interesting points! You should not believe on what is written in the watch, unless it's from a good brand. For example, I already scuba diving on the ocean with a Swatch with 30min of resistance. I was expecting to break the watch (I was testing the watch) and it passed. It was 20 years ago, and I still have this watch!
I have a citizen eco drive with 100m water resistance and no screw-down crown. Owned it about 10 years now, and I have taken it in the pool and ocean, shower, etc. Never had an issue with it as far as water getting inside. Thanks for the video Oleg!
It has 10 years of wear and tear on the gaskets now, who knows how much longer it will last? Better give it a service if you value it 👍
Famous last words lol ... Good to hear you've had that luck, just remember one thing though: the seals and gaskets work, right up until they fail. Now would be a wise decision to have the seals and gaskets swapped out so you can enjoy another 10 years worry free.
@@mikec3454 I don't wear it that much anymore, as I've gotten into mechanical watches nowadays. I just had it serviced and put a leather strap on it so no water for it anyways!
Chris Kiederer nice! Good call... yeah, only have a few watches on leather straps, I definitely take precaution getting the straps wet.
I've swimmed with multiple 30m resistant watches. Here's a quote from Wikipedia:
"Movement induced dynamic pressure increase is sometimes the subject of urban myths and marketing arguments for diver's watches with high water resistance ratings. When a diver makes a fast swimming movement of 10 m/s (32.8 ft/s) (the best competitive swimmers and finswimmers do not move their hands nor swim that fast) physics dictates that the diver generates a dynamic pressure of 50 kPa or the equivalent of 5 metres of additional water depth."
I love your reviews! An important point that you overlooked is that ISO certification costs a lot of money, and, in fact, tests watches not only for water resistance, but certain other parameters as well. For this reason micro brands tend to skip it, and yet test the water resistance of their watches rigorously. Thus it is safe to assume, in my opinion, that diver watches manufactured by quality brands such as Phoibos, Zelos and Long Island Watches (for example), are indeed fit for scuba diving.
Okay...I’m going to chime in as a certified lifeguard who regularly dives to practice saves in deeper water than most watch people will ever take their watches. I swim with my 50m timex expedition and it’s never had an issue. I also dive with my 100m watches. I would rather have my gshock or my duro, but I’ve never had a problem with 50m timex swimming.
I agree with nearly everything you’ve said though I’d definitely take a 100m WR watch swimming if it was from a reputable brand even without a screw-down crown (but probably not surfing). Same with a 200m non ISO if I went diving (which I don’t do anyway!).
However, the entire rating really needs changing as it’s extremely misleading. I wonder how many time people have gone swimming with a pricey 30m WR watch thinking it would be more than adequate only to find water got inside and it was ruined. The manufacturers often don’t even include the rating instructions in with a new watch when you buy it which is unacceptable imo.
do pricey 30m WR watches even exist? why would even be pricey if they are just 30m... hard to believe considering you can get a 100m WR watch for like $20
@@user-wb4dm4gu3g i have a garmin watch which has 30 m rating which was like 200$
@@user-wb4dm4gu3g ummmmm yea they do lol. Not every watch is meant to go swimming with. There are a ton of luxury dress watches that only have 3 bar or 5 bar resistances.
Based off of the "watch and learn" video on this topic from Mark over at long island watch, I can say that the amount of impact from water needed to significantly increase the atmospheric pressure on your watch would be so great that damaging your watch would be the last of your worries. Also diving at, or past, 100 meters is insane. At 300 ft below the surface you are talking about serious technical diving involving tri-mix gas and staged tanks for long decompression. Frankly a 100M water resistant watch from a reputable brand should be more than enough for SCUBA diving, no less taking a dip in the pool.
Also, while showering does, in theory, stress the rubber gaskets in your watch, I have yet to see any significant evidence that it actually poses a threat to it's water resistance. If anything I have mostly seen anecdotal evidence that it is totally fine.
Casio digital watches with 50+m are absolutely fine for showering from my experience
Gshock 200m can get for cheap price and also can be use for decades.
You telling me this now?? Been using seiko snk805 with 3ATM for 6 years now. Ive been swimming with it everytime and had no issues 🤣
I've been swimming with my beater Croton 30m watch for a decade. Not a single issue.
Very interesting. I remember I got a Fossil as a gift, it had 30m we, were it in a pool and it leaked, of course. I did not know at the time with these ratings meant.
The only watch a wear in water is my G-Shock, it’s 200m wr, never had a problem with water.
If you are actually going diving, the warmest the water would ever be would be in the low 80s F. In many cases professionals would have to be in very cold water. Showers or hot tubs can be way over 100 F, it is possible you could get water ingress do to expansion from high temperatures.
My belief is - it's better be careful than sorry.
Expansion causing potential leaks is actually the opposite of what happens. The rubber materials the seals are made of are much more susceptible to expanding than the metal housing of the watch itself.
Because the seal expands more than the housing it’s in, it actually makes an even better seal at higher temperatures
I swam with my Seiko 5 30m wr and had no problems. I don't do it constantly just a couple of times I did it. I never take a shower with a watch. Warm water and soap don't work very well on seals. I use the plastic Casio 100m wr often for swimming and never leaked.
Well said. Not many people like hearing the truth, but you have my respect. And everyone's respect, who loves watches.
I’ve been wearing the same Vostok Amphibia in the shower and to bed for ten years. They can take it.
The shower is nothing lol
The Amphibia is a very good watch. I swim with them.
Dead Monk i have one from the mid 80s that i do everything with
Amphibia doesn't count! lol
@@24hourstime That's your opinion , just your opinion.
I’ll take my Vostok deep, it will only cost me 60 bucks to replace it 😂
Also, they can go really deep underwater, as pressure tests show.
You’d be crushed before your Vostok 🤣
VOSTOK!
Yes and apparently their WR improves as you go deeper which is genius!
Informative video. I never swam in water under 100-meter water resistance, the depth ratings are different than the build quality for sure. I take my cheap Casio's for swimming the plastic ones. If it breaks no big deal but never had a problem. You made a good point about taking them in the shower. I never have done that but I did not realize soap can damage the seals or gaskets.
Most people’s watches will never see anything past 20 feet of water ….
Saying you need 660 feet of water resistance to expose a watch to any form of water is like saying you need a Bugatti to take your kid to school so they’ll never be late ….
Have Casio Royale 100m WR and went diving with it no problemo 😂
@John R i think that what helps Casio Royale and its rounded version os the acrylic crystal, its flexible and gets compressed under mpre presure, that adds to the WR i guess.
There's an review about Casio MRW200H (Casio budget diver style watch 20$) and the guy dived with it more than 100m and its still working flawlessly. The watch only rated for 100m its crazy
I swim with a few of the square Casio digitals ( not G-shocks) at 50 and 100m WR. Never a problem.
@@MPD90 I believe that I understand the point that you are trying to make, i.e., that in your opinion, regularly taking Casio digitals rated 50 and 100 m WR into water is a risk that you would not take. That is fine, for you. The comparison that you use to illustrate your point is, however, an "apples and oranges" piece of flawed logic. Personal safety habits when crossing roads have nothing to do with how a person has utilized a given watch brand at a specific WR rating. I appreciate the attempt at expressing an opinion, and I wish you a good day.
Don P yea. A better analogy would be. You crossed the road when the light turned green and you were fine. But one day you crossed the road when the light was red. And you died. Sooo if your watch says 50m. Don’t go past 50m. Easy
very enlightening video, finally someone explains it simple and easy to understand. 👍🏻
Thank you!
And wrong
Excellent. You answered some questions. More vids like this would be a hit.
Thank you!
Beg to disagree. I have an old Timex Indiglow from my late grandfather, only 30m WR and I have washed it under running with toothbrush many times with zero issues. Same argument with 50m WR Seiko 5; swimming was not an issue, even slalom water skiing yielded no problem. The purpose built skin divers of yore were usually only 100m WR, the original Zodiac Seawolf @ 200m WR had a snap on case back and push crown.
@@MPD90 to each their own opinion. I have done it, so that's not opinion, it's factual.
For over 20yrs I wore the same 100m (screw down crown but not dive watch) as a beater, insomuch as I didn’t once remove it in order to do anything in particular.
Each day it would be in out of hot soapy water with frequent swimming, high impact sports use, occasional high diving (the very high feet first variety but don’t think the watch knew that) adventure stuff and lots of DIY usually resulting in being covered in paint and all manner of oil, dust grit and gunk on a fairly regular basis.
When washed and buffed (plastic crystal so easy scratch removal) always looks better than new (thank you Duraglit).
Never leaked and never* lost more than a second a day. *Serviced once at 15yrs.
The moral... if you go diving make sure you have a proper dive computer. For everything else look after it but don’t protect it, wear it.
i worked two years as a lifeguard and used regularly my cheap vostok russian watch that is rated 3 atm. I used it to dive up to 5 meters depth(max at our pool) and i also fan of sauna and russian saunas up to 120celcius degree. Worst that happened, i ruined my leather strap due to water and chlorine. Oh also hot tubs. Doesnt leak and i still wear this vostok while i am writing my comment.
Trial and error.. I used a Casio F91W and a Edifice while scuba diving a few years back. Dont think there is a single Casio out there that you could NOT take diving. Perhaps the old calculator.. I never dive with anything too expensive in the first place.
Absolutely correct. If one would a 100M watch to 100 feet diving and it floods, it will be the divers fault and have no warranty coverage. If it is an ISO rated diver watch, they are each tested and should be safe to take diving.
Thanks,Oleg. Happy new year to you. Give mr Bond a big hug from me. Best regards from Adrian in Sheffield South Yorkshire England 😀😺
Happy New Year Andrian!
How do companies get away with advertising that a watch can withstand 30 m of water pressure when you can't even swim with them?
I use my Seiko SNA411 everyday - shower, bed, swimming pool. 7 years later, it still works just fine. Same batteri even. 200m.
Why the shower? It’s a real hassle, gets in the way. Never understood.
Finally found an easy to understand video about water resistance on watches. Thanks Sir.
Orient Triton is JIS certified for 200 m diving from Japan even though it's not ISO certified.
It’s my understanding that J I S is actually more rigorous and A higher standard than ISO...
I just bought a Cressi Manta 100M divers watch. Do you reckon I can dive with it (under 40M). Whats the difference between 100m and 100m divers watch WR?
All good advice Oleg. The only watch I wear in a swimming pool is the Casio Dura because it’s new and IF it failed (it won’t), it’s cheap to replace. Been honest that was an experiment anyway as I can’t see a good reason to wear one if your just going for a swim. Any other water based activity I never wear a watch. End of.
I have used a 30m waterproof watch and it is fine to swim with and dive into a pool for long periods of time
One thing that is missing from this video, in my opinion: the process used to rate water resistance. What I mean is most people who are not into watches or who are just getting into it will take a water resistance rating at face value (ie “30 m” means I can take my watch 30 m deep, which is not true. They then don’t understand why they cannot wash the dishes while wearing that watch.
So, if a big manufacturer (say, Casio) says that their watch can withstand 100 meters, they are lying? Explain that to me. Dynamic pressure is minimal, and things are rated with extra margin. So there is no reason why a 100 m watch shouldn't be able to go that deep.
Thanks for this video. I learned a lot about this subject.
Good stuff! Thanks for the helpful information!
👍✅ I ruined a couple of watches many years ago they both said 50 m water resistant… That was before I researched a lot of this information! I wish this wasn’t the standard because it is confusing and I’m sure a lot of people have done the same thing that I did… It’s also pretty misleading… Nevertheless, we are stuck with it! Just about everything I buy now has a minimum of 100 m (With the exception of two dress watches).... most of my collection is 200 m plus… Swim with all of those and never had a problem! Thanks for the great video
John Buckmaster What were the ruined watches?
Question about 200 meters WR, NOT ISO certified. Is it safe taking it scuba diving to a depth below 20 meters?
Hi Oleg and Mr Bond , mate I agree with everything you said about the water resistance , however I have a submariner homage by Reganld 30m with screed in solid case back and push pull crown with gaskets so I decided to test it in the pool , I've worn it in the pool every summer at least 3 times per summer and it's never let a drop of moisture or water in it so I guess it does get confusing ...
Great advice and tips Oleg thank you for another great video ...
Thanks Trevor! There are exceptions to this guide.
@@24hourstime Hi mate , yes but I think it's just safer if we stick to the guide that way no warranty issues etc etc can arise . I just test out the cheap watches and honestly the results are surprising .
Oleg and Mr Bond you guys run a great fair watch review channel , I like the look of Bonds nato straps it's just a pitty I do not like wearing them maybe because I've never had a good one , who knows in the future I should try a Bond nato strap . I'm Looking forward to your content in 2020 and you guys are pretty popular here in Australia...
Can I wash a watch that has 30m resistance in the sink ?
I went free diving with my 100m pulsar, at a maximum depth of approximately 10 meters. It’s still okay and I don’t have any trouble with my watch! I’m curious if you can really dive with a 100m watch at a depth of 15-20 meters. I am probably going to test it next year when I go scuba diving because the watch was inexpensive…
Has anyone dived with a 100m watch?
Interesting video Oleg. Gshocks are rated at 200m with pushers and there's video evidence to show their integrity at those depths. A bit of an oddity would be the orient mako XL I got recently that has a both a screw down crown and a pusher to change the day but is rated to 200m so I would assume the design has been pressure tested at that atm? I do like the security of a screw down crown but would have no worries with a gshock below 100m.
Ps, Did you not wrap up Bonds present?🙂
Do you and others consider the Komandirski 100m ok for deep freediving, say 20 meters? I am watching your video while my wife is napping so I cannot hear it :( Nice channel!
would be cool to see more videos with tips for watches like this one. :)
Thanks Oleg. Great Guide!
Hi Bond🖖
Is steeldive watch reliable for diving ??
Thanks for that video, its so hard to explaine that to casual watch users, Now I'll just link them to this video🤣
:)
I think this video is missing something at the beginning. It should be explicitly stated that the depth ratings for watches are a complete and total misnomer, and not indicative of real world performance or capabilities. The rest of video is spot on! 30 meters really means this, 100 meters actually means this, etc
My 36 year old Submariner goes swimming, sailing, snorkeling, and even takes a shower with me every day. But it also goes back to Rolex for service at the recommended intervals. I take it to the shower because taking it off in a tile bathroom is much more dangerous (that resulted in an unplanned and very expensive service) than soap and hot water, which are mitigated by regular dealer maintenance. Just my thoughts on this topic.
I have a 20Bar water proof watch and at school we go to the beach to swim and is it safe to swim in salt water
Could I swim with a Citizen Eco-Drive Movement Promaster Diver Chronograph rated at 200m? Not doing scuba diving, but I’m talking about a 14 foot pool at most, but most importantly, just able to do regular swimming in general
Brilliant presentation.
I think you should do dedicated Bond only videos, Bond getting stuff for Christmas, Bond going out to play,whatever, I'll watch.
Maybe a second channel? lol
TRUE - but i see some video with test up to 3km (compressor test), aliexpress watch that agarantee 1km (or 1.x km) survive 3km and work - of cousre, he test in only few min on this pressure.
Watch that guarantee 300 or 200 m often - same chinese brand survive up to 1.x km - after this stop working - mechanical deformation of backgroud cap - up to 3km brek glas or deform backgroud cap too much and water leak.
Profesional brand? - for 1km same as aliexpress, survive 3km and no issue , some prof. survive that say, but after 1km - broken glass, leak or stop working - but this is still OK - i have 2 aliexpress diving watch that test this guy and i am happy - mechanicla automatic watch - old fashion seiko desing - btw. seiko movement inside ;-)
And funny fact - Bohemia brand PRIM on comunist time make desing copy of seico too - only not automat, but mechanical. "PRIM SPORT 2"
We have 2 things in Common...Love for Watches & Love for Dogs...Am a Diver & those are some valid points right there.!!.
So, I always hear if you get your battery changed the WR is no longer viable and I have heard watch places say not to go swimming after a battery change (even on 100M watched)
Is that true for quartz - dive watches?
Great video men thank you
Because gaskets can deteriorate over time, unless you have had your watch checked for water resistance or it is new, it’s best not to wear a watch in the water. Scuba divers use a dive computer these days. For snorkeling and free diving either don’t wear your watch or if it’s 200 meters water resistant you can take your chances it will probably survive.
My watch says 50m online but says 100m on the back of the watch. I assume because it's stamped on the back i use that rating regardless of what it says on the product page?
Just because a company hasn't paid for ISO accreditation doesn't mean something hasn't been built or tested to those standards. Research the testing methods used and make a decision based on that rather than general sweeping statements
I have a watch a tagheuer 300m quartz chronograph i used the pushers inside a mug while submerged is it damaged or is it ok i did not see any damage even after many years but i am still confused.
great video, have a question though - what do you think about a Garmin 50 m water resistant watch? i am not talking about a specific model, just a 50 m water resistant random xyz watch by garmin? .. looking forward to hearing from you
Better use gshocks for water activities. Garmin use for sport activities like cycling and joking.
I swim with 5 bar Garmin watch all the time. No issue.
Interesting.. I've took my 50m water resistant watch swimming in a pool and the sea with no issues. Also taken my 100m water resistant watch Swimming and snorkeling with no issues! Probably went about 3-4m under water.
100m isn't for diving though, Just provides better resistance for every day use. If you want a dive watch then it needs to be 200m and above. Screw down crown and case back. 30m is basically splash proof. But I wouldn't risk getting it wet tbh.
Yep made that mistake thought it would be fine to go water rafting with a watch that was 50m resistant... wasn’t working by the time I was done...
Yes hate it when people say they never take their watch off or they shower with it on I don’t care what it is
What about a seiko skx they’re 200 m but they’ve been iso certified so would that be an acceptable watch for scuba diving
Guys I bought an Orient Kamasu, it has no ISO rating but 200m water Resistance, is it okay to swim with it in the Ocean??
Are casio g shock resistant to diving ??
For Branded watches even down to 30m or even it says only water resistant is safe to swim wearing them.. I am 100% confident to say this because it am already 51 years old & I do not have issues with all my watches I soak them all in water even my casio f91w, tissot prx etc.. as long as you bought it bnew its safe.. but with vintage watches it is not assured even a vintage diver watch is not safe anymore.. that is why I collect bnew watch...
Great video. Would like to see some mention of women style watches as my wife has started her horology journey as well. Cheers
Great video!
Bravo Oleg! My sentiments as well.
Thank you!
How can I tell the difference between a screw down crown and a non-screw down crown?
Very nice video. I really enjoyed it.
Good suggestions. Very much practical.
Thank you!
It's rare to find "dive" watches rated at 100m ... for me, the 100m rating is really suited for everyday, grab-n-go watches, like a Rolex Datejust for instance. I think 100m with screw down crown is more than enough WR for any watch enthusiast. If you need something more for true diving, then get yourself an inexpensive Seiko SKX. One thing that you forgot to mention when talking about dive watch ratings - to achieve their ISO ratings, they are actually tested to withstand 125% of their stated depth. So a watch like the Omega SMP can go down to 300m plus another 25% for safe measures.
I've showered with every watch I own, it's literally the easiest way to clean a watch off, especially in the summer as dirt and grime builds up. Don't do it everyday, but to do it once every couple of weeks is absolutely fine.
but casio f91 is 30 meter but it beat some watches with 100m
Oleg, would you wear your Explorer for swimming and snorkeling??
Swimming maybe. But I wouldn't do any water sports in it.
Yes, the great Icelandic sport of. Snorkeling.
I dive to 2 or 5m Max. I dive with 3atm and 10 at but minimum for diveing is 100 m.... First sub was 100m wr
My boyfriend is obsessed with watches so I've watched quite a few watch videos. However, my question isn't about watches, it's about your cutie Mr Bond & how he just sits so comfortably with you. He's adorable....so I was wondering what breed he is. BTW, I do like your videos too😉
Mr. Bond is most beatiful Franch Bulldog in rear color in his breed and that is W-Coffee color, but mr. Bond have great size & overall muscular body in great shape, muscular neck, head and perfect muzzle with black mask, on first look people will think is a great Boston terrier, but his is great physical shape Franch Bulldog, 👌.
😉👍
@@mirobaic820 Thank you for the compliments! - Bond:)
Thank you for watching:) It's great that you're taking interest in your boyfriend's passion. Bond is a French Bulldog (3.5 years old). It took some time to train him to sit still for video intros. But now he loves it. As soon as I start setting up the camera he runs over and he's ready to film.
@@24hourstime Thank you for responding. Mr Bond is absolutely adorable & I look forward to seeing him in your intros. Nice training job!
That’s why I love my Vostok!!
Are you forreal? You wouldn't swim with a 100m rated watch without a screw down crown? Sorry man, that's a bit much. Realistically, watch brands test their watches rated 100m to levels beyond 100m. I have a Victorinox Diver rated 100m, take steaming hot showers, swim, snorkel with it all the time, it comes on a rubber strap for water activities. I will go as far as saying I'd wear any watch rated to 50m in the shower/pool, and even some 30m rated watches. Never. Not once. Had an issue. These are all Japanese watches like Seiko, Orient, Citizen, and some other brands like Tissot and timex, but they have been reliable and functional in the water. It's ridiculous to only expect a 200m rated watch to be water safe, I wouldn't say making people scared to get their watch wet is really all that helpful, it might be good advice for pricier watches between 30-50m, but again, I've never had an issue with any Japanese watch rated 50m and above, generally, there should be some truth to their ratings, unless you are suggesting brands are arbitrarily slapping 50m on the dial? Again, I agree with this for Chinese mushroom brands, but citizen, Seiko, etc, if they are rating them more than 30m, generally they are safe to swim with. If you are buying a durable sports watch rated 50-100m, it fucking better be able to come into the pool with me. The idolizing of 200m rated watches is getting old, it's unnecessary.
Lot of myths in this video. Watch people have vastly blown the impact of dynamic water pressure out of proportion. In my experience, if a watch is new, was properly assembled and comes from a decent brand, it can handle most things. I’ve swam with 30m rated watches with no issue. A good example of this is the suunto core. A watch with a depth gauge, but “only” a 30m rating. Moral of the story, buy from a reputable brand, keep up on maintenance and don’t listen to watch forum people about water resistance lol
Thnx for this man !!
But if it says 100 m, why can’t you go 100m with it? This doesn’t explain anything.
Totally agree with you. I wouldn’t swim or shower with anything less then 200m.
Wow. How deep do you swim? I have never gone deeper than about 20 feet without an air tank.
So, you think that when a reputable manufacturer says "100 meters" that they are lying.... So why do you spend money on such dishonest people?
lol, this old shtick again.
I would have started with the company caveat first. If a reputable company says 100m, I'm swimming with it. I can't create the force required to make 10x the atmosphere's standard pressure.
@@MPD90 yeah... I added an extra zero. Likely due to the extra beer I'd had prior to posting. My point still stands. If Omega, Rolex, Hamilton, etc. say the watch is resistant to 100m I'm wearing it in the water.
Seiko says their 100m watches are fine for swimming, shallow diving, even bathing and showering. When the company that makes the watch openly says it's okay, that's good enough for me.
I had a watch that was 100M water resistant without a screw down crown and I’m so mad. It broke 2 weeks after delivery even though I was doing underwater stuff that I knew was safe for that watch.
I had dozens of wr watches during my life time and till this day every one of them that had 100m water resistant or more survived swimming and diving untill 100m.
100m = more than enough than you need.
Great tips Sir.
I had my attention brought to a diving magazine that was commenting on diving gear the only watches that they actually said they would bring in the ocean are ISO certified seiko's or citizens I think the only watches I have that are ISO certified are citizen
Why are watch companies allowed to use these type of markings? They are misleading at best.
Cool water story bro.
My Luminox watches have 200m water resistant but no screw-down crown I wonder how they achieve that
You missed one very important point!
If the watch isn’t ISO certified we talk about a static pressure - so any move from the watch or the water will raise the pressure and you reach the limits much quicker.
ISO certified watches have been tested to the written depth with moving the watch which means you are save until you reach the written depth.
So a static pressure 100m can be reached while swimming, cause you move the watch through the water.
That's actually incorrect; Moving your wrist underwater does NOT increase the pressure on the watch whatsoever as long as you don't swing your wrist at a speed of over 20 miles/hour (if I recall correctly), which is also proved to be inhuman.
Furthermore, I found an interesting article on Hodinkee that quotes PADI, the largest professional dive instructor organisation, on how deep divers actually go in their different courses. Have a look if you are interested.
www.hodinkee.com/articles/seven-dive-watch-myths-deep-sixed
꧁Vam Heredur꧂ - If you believe in it....
Just move your hand under water or even in the air and you feel how the pressure raises...😇
So just a bit of thinking will teach you that this post is incorrect!
SkysaxonDragonslayer never read the article, but remember the original watchuseek thread that went over the math. Moving does raise the pressure, just not to a significant degree that would cause an issue. Unless your swimming as fast as aquaman or something.
Although I believe the biggest change in pressure that no one talks about is your initial plunge in the water. That should be the greatest level of change.
I do not understand the anecdotal statement regarding never taking a watch to the shower, even if the watch is certified to withstand 300m. The soap gets rinsed immediately in a shower so where is the "degradation" coming from? The shower water is just around body temperature so how is it much different than just wearing it on your wrist? I guess what I'm trying to ask is has there been any SCIENTIFIC EVIDENCE regarding this statement? because to me it sounds like fitness experts claiming you need to eat 6 meals a day in the 90s and 2000's, or something that gets spread around just because.
i have a seiko 5 100m water resistant. i used it in a cold spring, then immediately moved to a hot location. water went in.
Well, Casio rate their 50m watches good for swimming in the manual so i tend to trust them. A watch is a tool not a baby, unless it is a very expensive watch :-)
100m is no problem for swimming if the brand is well known. Now, if you open the case back then it is another story, even for a diver 200m. You should be very careful so the gasket is at its place.
