Sumergibildad de un reloj. Bajar a x metros ó aguantar x presión?

El forero de WUS Lysanderxiii puso ésta magnífica tabla:


Seppia, un florero de Güs, convencido de que eso de que hace falta un 1000M con una corona triplemente roscada para meterse a la ducha es una soberana estupidez, mete un Casio digital de perra gorda y el popular Military de 50 eurillos bajo el mar. Vemos qué pasa…

En ese foro postean en la lengua de la Pérfida Albión, así que tirad de Guguel Transleit si no lo llevais bien.

Reminder: my purpose here is simply to light heartedly ridicule and belittle as much as possible all of those brands (and people) who try to convince you that 100m WR is not enough for showering, or that the absence of a screw down crown basically prevents you from wearing your watch on a rainy day.

I try to do this by scuba diving with the cheapest possible 30m WR watches, and and trying to see when they will eventually fail.

Unfortunately this time my dive trip was pretty disastrous.
We had planned a pretty intense 4 dive day, including a deep dive in the morning (Spiegel Grove) outside of key largo, but first the other divers that were supposed to dive deep cancelled, forcing us to join the shallow dive boat, then my buddy suffered some nausea in the second morning dive, leading to aborted afternoon dives.

So this time the test could not be as extensive as the first time.

So we have our old contender, nicknamed Poseidon Lord Of The Depths, protagonist of the first dive test.
This is the possessed Casio A158W-1

Here seen in action while spanking most 40000m WR divers around the Spiegel grove in April:

The second is a recently purchased, $59 snk805 automatic from seiko, also a 30m WR watch, featuring an absolutely non screw down, minuscule wobbly crown, a plasticky feeling display case back and the overall feeling of a watch that could not survive an accidental beer splash at your typical barbecue party with multiple drunk friends (I happen to do this a lot, if you don’t please don’t judge. Also, I have an awesome life so you should probably consider inserting some more beer induced drunkness among your circle of friends).

So how did they perform?

We weren’t able to dive below 9 meters unfortunately (still approx 20 times deeper than a hot tub though), but…

Beginning of the dive:

Later

My dive buddy (he has a DSSD but he obviously thought 9m was too much so he went watchless)

After an hour:

So again, to the surprise of nobody who ever actually dove, a relatively new, cheap 30m WR watch from a respectable brand survived a dive.
The Casio on the other hand survived after having already endured multiple dives a few months ago.

I expect them to fail sometime obviously (all watches will fail eventually), but will continue to test them till they do.

On my next dives, probably happening this coming winter, I will bring both the Casio and the seiko, plus a new test specimen.

Do you have any 30m WR, cheap watch from a respectable brand to recommend? I was thinking a swatch.

Here’s the two test survivors after a thorough rinsing

Wait, this seems kinda dark, let me look up

Well, it is dark, I wonder how deep we are

Oh.
40m?
I thought you needed a bathyscaphe to come that deep.

Y ahora… el Casio.

We often see around the forum new topics asking questions like: “can I shower with my 8000m WR watch?” or “can I be at the pool with my 100m WR watch?”
Unless these questions are a sort of preemptive excuse to get a new tuna (in which case I fully support it and would answer "no! Are you crazy? You NEED a tuna for your pool party!), I always thought the risks and effects of water on watches have been extremely exaggerated within our community.
We often hear about dynamic pressure (which I think is BS) and other hazards.
I had no way to prove my point so I decided to make a test myself on my recent dive trip to key largo.
Enter the Casio A158W-1, a 30m WR watch available on Amazon for less than 15 bucks:

So I set up an prepare to get wet:

Since it is common knowledge that a Rolex DSSD is about the minimum you need to stand a hot tub, I am sure my Casio will stop working as soon as I jump into the wat…

Oh.

Well, it is sure a matter of time, the light seals can probably stand a couple minutes but certainly after a while everything will break and the watch will fail…

Uh?

Time goes by…

I go through my dive and the watch keeps ticking…

Well, that didn’t go as expected really.
Back on the boat I was puzzled, and quite sure that the watch will eventually burst into flames at night, succumbing the unbearable effort it went through during the day.

In the morning I woke up, and to my biggest surprise, the $15, 30m WR Casio was still working.

Upset by its arrogant will to live, I decided to give it a lesson: I was about to dive the USS Spiegel Grove, a ship wreck situated in approximately 30m of water.

How dare you cheap watch resist the hardship of the deep? Why did you upset the gods of water resistance and dynamic pressure?
We will see how you handle 20m!

Mumble, pretty well apparently.
How about 24m?

This is not going as planned.
30m!

30m for longer time!

Well, I am starting to feel uncomfortable, so cut to the skx009 to distract me a second

Midway through the dive and this little bastard is still alive.
I am now convinced this watch is capable of black magic, and start to fear its wrath.

Back on the boat, surprisingly the Casio did not explode tearing apart my arm in the process to punish me for having tested it.
I consider myself lucky I am alive (I should probably say that it let me live)

This morning, it was still there, defiantly working and keeping great time.
I will sacrifice small animals to it in order to avoid his vengeance.

So, what can we conclude?
While obviously 1 test cannot mean ALL 30m WR watches can stand diving (that was not the point of this test), I think we can confidently say that fear of water in 100m WR watches and above is probably overblown.
I have learned, to my utmost surprise, that a 30m WR watch is water resistant to… Uhm… Approximately 30m (WHO KNEW?).

Lo del Casio me lo esperaba sin problema. Si de crio recuerdo perfectamente que un amigo bajaba a diez metros a pulmon libre dia si dia no todo el verano con su Casio Melody machacadisimo. Mi amigo acabo sordo y el Casio funcionando sin problemas.

Pero lo del Seiko Military me ha dejado a cuadros, maravillado. Yo tengo el mismo, averiado eso si porque se lo preste a la MDD, caida tonta y algo se solto dentro (armis cerrado, a las MDDs nunca les regaleis correas abiertas) veras como se jubila antes Juanra que yo me acuerde de mandarselo.
