What does water resistance mean? - Watch and Learn #6
Вставка
- Опубліковано 7 лис 2016
- Today's video is part 2 of Watch and Learn #5, which was an overview of water resistance. In this video we explain the various water resistant marks, and the specifications used to rate water resistant watches. We'll end with debunking a myth about dynamic water pressure and its effect on watch seals. Warning! Math and Science approaching!
EDIT: The 2nd equation should result in 4500 Pa, not 450 Pa. That is about 18 inches of water; still inconsequential but an error nonetheless.

Outstanding!!! Keep it going my friend.
Nice one Marc,
Best regards,
TGV
P.s. No WWC?!?!? ;-)
The Urban Gentry wwc very important! ;)
it 's actually because of your channel that I got to know this channel and this series. So thanks for that. Both great channels!
Thank you sir! An extreme feather in my cap coming from you!
Ha, I did do it. I'm wearing a Seagull and a Bulova Accutron, but I had to edit it out as it was horrible and I couldn't get it look good. Next time!
As an engineer and a diver I liked the equations to prove the negligible effect of dynamic underwater activity in relation to static pressure. Love your site and your common sense approach.
HOLY SH** Marc, that was honestly the best watch technical video I have ever seen. I honestly got so hype when you brought out the equations. OMG. best ever.
LOL, thanks.
This video really sold me on Seiko watches, I had no idea the difference in 200m resistance and Diver's 200 was so great, excellent and informative video!
Just started watching this series after I got a bit into watches. It's awesome. It really is a good sum-up for total newbies like I am. Thanks for all the effort and thought you have put into each one of these videos! We appreciate it.
When I find the time I will binge watch an hour or so of your videos. This is the first I have commented on. Coming at this subject as a building engineer I give this video a 12 on a scale of 1 to 10. Just about every topic point covered and super easyu to understand. Great work, my friend.
We should apply ISO standards to politics and journalism. A standard of honesty must be met and maintained to become certified and untruths will result in revoked certification, rendering you unable to work until certification standards have been met once again. Marc, you're a genius!
Haha, not really, just a watch guy. But thank you!
i got extremely invested when you started showing the equations and i am not even an engineer or in college! dude knows his stuff! glad i know more about the water resistence with my gw9400 coming!
LongIslandWatches and UGC are two of my favorite channels on UA-cam.
Great work Mr. Marc!
This was even better than Part 1. And frankly, the math was the best part IMHO.
One of the best watch channels ever, you actually learn something useful. Thanks very much.
I've newly subscribed. Scuba dived many decades ago - it was fun, but nothing I felt I just "had" to do. Plus, it can be expensive. However, I never lost my love for dive watches. I. Own many at varying values, but always end up back at Seiko. They are such great watches at such a great value and can be Modded relatively easily. Love these videos. These are by far the best and clearest on the Internet. You are a great teacher and presenter. Thank you for scratching our dive watch itch!
Thank you for watching (and learning!)
Awesome Marc, very kind of you to inform us making us that bit wiser! Cheers Mate!
Just started getting into watches and Long Island Watch was recommended to me by a few people. This is by far the most helpful series that I have yet to see. Look forward to seeing all the rest of content.
Great, thanks for tuning in!
Amazing video series! Just got done with ep 5 and 6, I feel enlightened! Thank you so much!
Hope you keep this series going. I just suscribed.
Thanks Marc! That was excellent. I use my dive watches for diving and they are both DIVER rated. I had no idea the testing was so stringent but now I feel even more confident that they've passed the tests. Also thank you for dispelling the myth of dynamic pressure. I was talking with a buddy this week that is an avid swimmer and he brought this up. I had no idea what he was talking about.
Great video and a clear explanation on water resistance Mark. As a scuba diver, it gives me some assurance that watch making industry has standards to meet in adding to safety. Thanks!
Yeah, Mark, really good and insightful videos. I'm really waiting for each new episode and learn A LOT!
The definitive video to the water resistance question. Great job! I also appreciate the use of formulas at the end. Completely removes any confusion or doubt regarding that issue.
This is probably the most exciting watch video ever, great work!
Absolutely love this series, I cannot say it enough. Great knowledge to be had. Keep the videos coming Marc!
Thank you; will do!
Great video, watched the previous one to. I look forward to more of your watch & learn pieces 🙂
Thank you for this, far more information than I sought, none of it boring whatsoever, and it made my watch buying experience more fun. Kudos.
Thank you Mark for taking the time to make these videos. I have truly learned a lot from you and you inspire me to further my knowledge of horology. Cheers!
Thanks for taking the time to watch it.
I’m really glad I found your channel from the Urban Gentry, I’m binge watching a lot of your videos even the old ones as you can see, I really appreciate your explanations and your attitude, you seem widely knowledgeable and I’m sure your friends and family appreciate you very much.
Thank you Mark. Very informative again. I am enjoying and learning from your great series!
Great, thank you.
Love the content you put out. More power to you, brother!
Thanks!
The pressure equation was the cherry on top. Amazing video!
I brought my Seiko skx007 from you guys . The service was great and the watch is beautiful , thank you for posting .
Clear, concise and to the point. Congratulations 👏
I always learn so much from your videos,please keep doing them.
Great video! As a mechanical engineer myself, I appreciate the technical engineering discussion. Keep these videos coming!
Watched lastnight Mark but unfortunately on an Xbox One can't comment even signed into my UA-cam account so commenting now. Great video. I'm watching your older videos slowly but surely! You have not aged from this old video to 6 years later in the present👊👊👊👊💪
Nothing better to clear guesses and myths than bringing up the math.
Fantastically informative! Thank you so much Mark.
Wow - love the engineering lesson in the end. You teach with great humility.
Great video again Mark. This is so educational and different from other channels. Keep them coming.
Thank you. Glad you are enjoying.
Excellent. Thanks mate. I'm pretty new to this but I love watches. Your explanations are clear and understandable to a layman like me. Keep it up.
Just loving these videos , great content. Keep up great work👍
Thank you.
Another great informative video Marc! please keep uploading.
You got it!
Explained so well! After 10 years of watch interest, I still learned so much from this video, excellent job!!
Never stop learning!
Dear Mr. Mark,
I am bingeing on your series and I should give you my regards for all of these information/facts you are sharing.
From a fellow engineer, salute.
I just love your lessons....Amazing!!
Math checks out. Great vid, thanks for doing that.
Brilliant video! My one nitpick: the little g in Bernoulli's equations is not the gravitational constant. It's the local acceleration due to gravity. The gravitational constant is big G and does not change.
It really is a nitpick. Your explanations are wonderful. It's clear you have a background in engineering.
Love your videos!!!!! So interesting and informative 😘
loving these, looking forward to the next one!
Me too. I really enjoy making them.
Thanks for another fantastic video, Marc! Love these. Stony proud! :)
Haha, thank you!
Thank you for sharing your knowledge. Really great video.
Marc, very insightful. Love your passion and unique product line.
Thank you for watching.
That was very informative. You are a very good teacher, thank you for your knowledge.
Bless
Loved the video .. especially for those equations....brought back some other equations in my mind
This series is brilliant, thank you! Very informative, very easy to understand :)
Thanks!
wow great Job! Super informative and useful! Thank you!
Thank you Mark, I'm a diver and i liked this series on water resistance
Thank you for making this so easy to understand. Will you start a math for dummies series?
Maybe in the future! : )
Great explanations. Thank you. 👍
I am so loving these videos!
Great, glad you are enjoying. It will only get better; I hope!
Thanks Mark. I’m a bit late to the party, but this was by far the most informative video on water resistance I’ve found on UA-cam. Great content.
I learn, therefore I thank you.
Thank you DesCartes!
Ha! Good one.
Remarkable. Absolutely remarkable. This is an amazing video. I've learned a lot! Thanks for posting it!
Thanks for checking it out.
I was just doing wind calcs for a building today using the dynamic pressure equation. Excellent video!
Another one out of the park, man! Thank you Marc.
Thank you!
Great info, thanks! Esp the dynamic pressure debunk. Also the info on ISO 6425, great stuff
Fascinating. Thank you. And well done for the Physics. Very welcome.
Thanks!
brilliant video, really getting into your stuff!
I never believed what was stated about movement force on a watch in water was a valid concern. Since I understand the math and physics of fluid dynamics I did not bother calculating it. I knew all along that the change in pressure exerted on the watch and seals due to motion would be nothing, relative to the weight of the water at X depth. Pressure is a function of resistance to flow, and a watch presents very little resistance. I concluded the concern about dynamic water pressure effects on watch seals was pointless. Glad you did the math though.
Your videos are getting better and better!
Appreciate that.
I'm really enjoying these "Watch and Learn" videos, Marc. I'm not a watch guy. I now wear one because it's my fitness tracker, but I've never owned a mechanical watch (not sure I've even owned a quartz watch, now that I think of it). But I am fascinated by clockworks and intricate devices and machining. I happened to catch a documentary in the early days of HD that showed the creation of couple high-end, Swiss mechanical watches and I was fascinated by it.
For some reason, I started to wonder exactly how jewels worked and what they were made of, which brought me to your #2 video in this series.
Now I'm making my way through all of them.
For the record, I've been interested to see what you looked like, so thanks for showing us your mug.
Fantastic series!
Haha, thanks so much for checking out the series.
Very informative, thank you!
Great video. Love this series. It takes the term, "watch nerd" to a whole new level.....and that's a good thing!!
Thank you!!!
Excellent and infomative as ever, and a nice change to put a face on the voice we all know.... Looking forward to the next watch and learn, as l'm sure there's still a lot to cover in the future!!!
There sure is; stay tuned!
Excellent episode, Mark, thanks!
Glad you enjoyed.
Mark, you are killing it! Absolutely love these videos! You're hitting on perspective for us watch geeks that I personally think is lacking. We ALL purchase a watch because we love the way it looks but for my engineering brain I want to know how it works. Thank you!
We think the same then!
Fascinating and informative video. I look forward to more.
Me too! : )
Great info, I just found your channel yesterday (recommended by TGV), These watch and learn series are my favorite, everything I wanted to know, nicely presented in an hour or so. Are you planning to do more of these, and if so, on what topic?
This was the 6th installment. I try to get one a week, though coming into busy season it will be tough to keep them going, but I plan on continuing them! Tell your friends : )
"Everyday is a school day" is something I sprout to anyone that wants to listen. As a non-engineer , I learn heaps from your vids. Is it no wonder I purchase from you, thanks for the lesson.
Thank you!
Dude. This is awesome. It's an old video but I have to say your series of educational materials for watches are hard to find.
This is fantastic to know. Thanks a lot 👍
Thank you! Very helpful topic. Great idea on fluid mechanic, the dynamic pressure is sometimes I never considered. I love your engineering perspective on to the watch.
Thanks!
love your videos Mark
thanks. that math's/physic's lesson helped me a lot understanding the trade [wristwatching: tissot seastar chronograph, 30 bars, blue-black dial - i love it].
Great helpful stuff!
I just ordered a Seiko SKX007K1! It's great to learn just what value for money I'm getting with such stringent criteria required to classify a certified diver's watch.
I'd bought an Orient Ray 2 a fair few months back, but sadly the crown had popped out while I was swimming at the beach and it was too late when I realised salt water inside the dial. Note to myself - always check the crown before entering water.
I'm looking forward to receiving my new (and first) Seiko and I love that Long Island Watch has an associated UA-cam channel. You provide a lot of useful information. (-:
- Aussie consumer.
Thanks for checking it out, and enjoy!
It's like I'm going to online watch College! Great videos thanks.
Tuition free!
WO WO the man behind the hands
love you content . you are the WIKI watch of youtube congrats.
thank you! Great moniker!
Thank you Mark, highly informative vid!
Thanks.
Really good quality videos on this account!
Thank you.
Great explanation across all videos. Thank you.
Thanks!
Phenomenal video!
Very helpful. Thanks Mark
Excellent. Many thanks.
Wow how have I not seen this channel before. By far the best explanation on water resistance I have seen. And i loved the tiny bit of maths at the end.
Greetings from a fellow engineer!
Thank you!
Thank you Marc, great information!
Glad you enjoyed!
This was so inspirational !
wow I have learnt soooo much from this vid and so glad I subscribed to your channel!!!!
Great to hear!
Very informative.... Thank you Mark.
Glad you enjoyed it.
Great stuff again Mark!
thanks.
So here is my question. Since we figured out that movememnt in the water doesnt really put any significant additional pressure to the watch and since 30m WR watches have been tested to 3atm pressure, WHY shouldnt I go swim with it? Im really curious because the answer usually is that you're moving, while swimming and that adds more pressure, but you yourself did the math and thats wrong(i mean its way less significant than what they mean). According to the math i could even dive with that watch to ~29 meters. A simple 3BAR water resistant watch. But again in the end you say that what we should get out of this video is that 3bar WR isnt suitable for swimming, which contradicts your math. Im confused.
Indeed it is WR to 3 ATM, but watches age, not every single one is tested, etc. So to be safe you should not.
I have a quartz Rodania since 2002 with 50m WR. Used it many times while snorkelling at depths around 5-6 meters every summer. I have even cleaned it in 1:1 diluted spirit of salts (~9% nitric acid) to clear the gunk that accumulates over time. I have had is battery replaced in the store I purchased it and in other stores, too. Never had any signs of water getting into the watch. It has a screw in case back. I believe good brands usually under-promise these types of specs.
