Is 50 meters water resistance too risky?

I see the confusion:
50 fathoms does not equal 300 meters nor does it equal 1000 feet.
Also 300 meters does not equal 1000 feet.
50 fathoms does equal 300 feet, considerably less than 300 meters, or 1000 feet. Discounting the “Fifty Fathom” model name, what is this watch actually rated for, 300 meters or 1000 feet?
And yes I am being silly and sarcastic.

And that is how people are getting confused...

good point, better than good if there is a word for it, i'll have google "what is better than good" to come up with a better word

Use a thesaurus, it’s better than good compared to a dictionary for this task.

Relevant? Hardly. If your really don’t know that Fifty Fathoms is the model name and the the 1000 feet is just an approximation of 300 meters or that you’ll never be diving to this depths anyways. You really need to consider a new hobby.

So if a speed sign says 60 it means 60.
If a bridge height sign is 4.2m its pretty sure it’s 4.2m underneath.
So if a watch says 50m 😉


like your reply, i'd love to live on the planet where watches that say they're rated to use at 50m can be used at 50m (adhering to the manufacturer's specs of course), the link you gave me to read on watchuseek says otherwise though, i won't patronise you by showing a screenshot with it highlighted because i think you know already what it says
the original point we were discussing has migrated a little bit and i've forgotten what we're disagreeing upon now, or maybe that's just me, but any of you, if you can tell me what it is you think i'm challenging in your posts please let me know because i think there's at least some overlap

Quite a retort considering i was agreeing with your post, at the end you said you were being silly and sarcastic, so i added but relevant, because what you said about feet/metres/ was true and i agreed with it, i did know it's the name of their model, and i need to consider a new hobby because i won't be diving to 300m? Or because i agreed with your post? Bit weird old chap, you ok?

the link you gave me to read on watchuseek says otherwise though

Where? It does says this though : "The Standardisation does not indicate a watch maximum capacity." meaning my Seiko which is rated at 600m may not leak until a 100bar pressure is applied, or that a 5bar rated dress watch may survive up to a 80m immersion. BTW not many people dive down to 80 meters.

Also saying that a 50m rated speedy is unfit for diving means that it can survive a 50m immersion by design when properly maintained, but is not particularly useful to a diver because it lacks some functionalities.

What trips you up is the marketing categories. When it is said waterproof up to x bars, it is waterproof up to x0 meters. If it leaks under warranty that is the manufacturer's job to make it right, even if they try to make you buy a 200m diver's watch to wash your hands.

You may also try using period and uppercase, those are useful.

If you scroll down to the section titled in bold "So what do all of this means?" there's a list of rated depths and they're perceived actual ability, i say perceived because i'm only referring to a link that was referred to me and not using it as anything to prove my point, just politely highlighting a contradiction between Standy's post and the link i presumed he supported the contents of, just playful banter is all intended i'm not out to take anyone to task for every word they type, yes you're right i shouldn't be so lazy with my typing, i'm capable of correct grammar but laziness takes over, i do make sure my spelling is always spot on and never misuse apostrophes, so i have some standards still

Yes, but that is not only related to actual water resisting performance. For example, marketers can say that for diving, you need a watch with ratcheting unidirectional bezel, lume at specific points of the dial and hands, screw down crown, function indicator, etc on top of rated WR. Usually, those watches are rated to 200 or 300m. Hence the confusion, some people think you must have 200+m WR to go swimming or snorkeling. No, you don't, but those features sure are useful sometimes.

You can very well dive to 40m with a 5bar dress watch, a Datejust or a Speedmaster on your wrist, it must be able to withstand the immersion (under warranty, if properly maintained) and if it doesn't, the seller or the guy responsible for the WR warranty should make it right. Water resistance rating is just that. "Actual ability" to be a dive watch is another thing.

Sounds like there are plenty of people out there really just don’t under stand the “maths”, the physics, or even the reality of the situation, and actually need the “don’t eat the silica packs” and other warnings.

I’m all for kids loosing fingers in fans.

They only usually loose one and tell a lot of people how they lost it.....

Dunning-Kruger on full display in this thread. The death of expertise is real.

Actual knowledge of engineering, being able to "do the maths", having industry training and brand specific training on this very subject is ignored in favour of gut feelings and vague notions labelled as "principles."

Funny how the depth rating on dive computers is never talked about by divers and most of them are only rated to 100-200m 😁

Just as funny as how the Speedmaster is qualified for space flight- which is an imperative for 99.99999% of Speedmaster owners...because they use it in space so often 🙄

"Yes" to the former, but hopefully "no" to the latter. Of course I have a personal stake in that. 😀

I totally agree that the lack of self-awareness about technical expertise (among some members of the general public) has reached record proportions, which is ironic given that a bunch of scientists and engineers just saved us from a global pandemic using impressive technologies that almost nobody understands beyond a superficial level. Of course, after four years of a prominent person who knew more than the generals and the scientists, maybe it's to be expected.

Fortunately, scientists and engineers are still being trained. Even during the pandemic, things are progressing. Ironically, this thread began as I was writing my Fluid Mechanics final exam, and I thought briefly about adding a question on the topic. 📖

Not sure why maths has to be in inverted commas, but anyway, if asking questions and proposing ideas, even ideas based on misunderstanding, is frowned upon it doesn't really provide a healthy foundation for debate, the opposite is to take the word of the majority and go with it, that's always worked out in the past obviously, but if they are the rules then i'll stick to them, no more curiosity as to why or how, or what if, my intention was never to come across as combative or stubborn, just thorough

It seems that you are deliberately missing the point, and I am really starting to think that you are simply trolling us. One doesn't take the word of the majority, one accepts the science when it is well-established, as known and explained by experts. There is no need for "debate" on this topic since the answer is known. Proposing ideas is not the same as spouting gibberish. I offered to explain, and you declined as follows:

C Concretepuppy
i'm sure Benoulli was a great guy but i'm not going to be using his equation so i'll take your word for it, and that does make more sense than what i'd been saying, increase in water pressure is inversely proportional to it's flow speed, the molecules being more tightly packed together and less room to move

This is an example of gibberish, and also demonstrates that you do not even know the meaning of "inversely proportional". 🤦

So what do you call someone who doesn't understand, doesn't want to understand, but still wants to promote silly ideas, and to have them valued and respected? Put this in the context of a topic on which you are knowledgable.

But space is everywhere, believe it or not earth is just a part of it......😉
