[@HarrisonElmore]

As a note: ISO22810 is the spec all watches have to meet. Dress watches up to dive watches. It’s designed to address ambiguity of water resistance in ‘watches, so yes, your watch meets those specific depths. Obviously most of us aren’t comfortable trying it, but they are. 🎉

As a keen metal detector enthusiast, I've found dozens of wrist watches in the ocean. From $1 to $1800 watches. The ONLY, and I mean literally, the only watches that ever survive the roughest surf conditions are Casio watches. They are unkillable. They can be slammed on rocks, buries meters below sand and tumbled for years and not die. I found one last night with a flat battery, been there at least a few years.

I have been diving in the Red Sea with exactly that Casio down to 40m. No problems, also years later. I have also dived with a F91W down to the same depths, also no problems. Wish I had the confidence in my other 30m WR watches. It is so confusing to consumers, as dress watches that are 30m WR cannot possibly do that

[@predragjo5977]

I'd say that the case material contributes a lot to WR. Its made of resin and the resin compresses under the pressure.

[@noisepuppet]

I've been wondering if pushing the buttons at that depth could let some water in. Do you use the buttons at depth?

[@dnichl]

​@@noisepuppetit will let water in for sure. it's just a few o rings that fit around the buttons. at that depth it would unseat, let out the air and not seal again. never operate buttons under water. same goes for water resistance rated physical phone buttons.

reminds me of a video where somebody put their f91w on a cruise ship anchor or fishing net or something at let it go down 100m+. came back fully functional with zero water ingress.

[@ianmaw66]

If it's like G-shocks I opened the back is holds the buzzer so it is not surprising that the buzzer stopped when you removed the back. There is often a tiny spring which makes electrical contact. Excellent video, thanks.

[@TheGrenadier97]

Safe pressure rating on the vintage 30m Casios is definitely deeper than what's stated, and i don't think most other brands have that same degree of reliability. It's as if Casio deliberately overbuilt the resistance. However, i've always thought that digital quartz are inherently more robust; i'm curious as to how analogs like MQ-24 and MTP-1095 (a dress watch) can hold against pressure.

[@Bljat47]

Sony. They lower their specs soo much on paper

[@ignaciopadilla5150]

Great video! Thank you for sacrificing a God Tier watch in proof that Casio 30m water resistance over passes its statement. Other fancy and expensive watches that claim 30m you can barely wash your hands with them. You showed this Casio did not just surpassed its WR ratings but also was submerged in water for a long period of time.

[@HarrisonElmore]

Agreed! It was far better than I expected.

[@huckinator]

This was an awesome showcase! One watch that comes to mind is the Hamilton khaki king. I own one and never once have ever thought about 50m of water resistance being too little. Then you watch a review of it and that’s on almost all of the negatives list for it. I think crazy water resistance requirements for a watch to be “good” is ridiculous.

[@dtuk22]

I Love this....proof that a $30 watch is better than ridiculously expensive watches. I couldn't fine a direct comparison but thats a greater depth than two Statue of Libertys stacked.

The caseback is used as the resonator for the piezo (beep), so it has to be assembled for it to work. You can actually delete the beep by putting a piece of tape on the inside of the caseback before reassembly.

I went diving for my yacht mooring while wearing my CASIO - W800H-1AV | Black Digital Watch. I bought it when a guy said this was all he needed when travelling around Australia. The only reason I don't wear it diving anymore is because I had a crazy elevator door in Malaysia, close on my wrist watch and it ripped one of the holes holding the strap spring bar. It could pop out at any time and fall of my wrist now. Best watch I had ever owned.

[@-----REDACTED-----]

So…I don’t know if it’s universal, but a mechanical engineer once told me that components usually have a designed safety margin of at least around three times the official rating. So while I wouldn’t expect it I wouldn’t be surprised if the actual failure point of the watch were to be around 90m… Edit: Well, I am impressed by that watch.

[@nojburns]

I believe the watch stopped beeping because you took off the case back. There is a very thin speaker on the inside of Casio case backs. This is electrified by a small spring that comes out of the movement and connects to the speaker. If the spring is still in the movement (they're very easy to lose) and you put the case back back on, I'm certain the speaker would continue to produce your beep.

[@techmadgeek]

Beeper requires case back to function. You will probably find beeps will return if you were the replace case back.Great Video, thanks for posting.

One thing to keep in mind is operating the buttons under water, I went into a swimming pool with an F91W a few years ago and the screen fogged up, could've been me fiddling with it underwater or something else, but I don't trust anything less than 50m anymore. Whilst there are people here who have been surfing, diving etc with an F91 or similar, those that break probably just discard it and get a G-Shock or other watch.

Generally you're not supposed to push the buttons/pull the crown on watches while they're underwater.

Wow, that is incredible. I had an suspicion that it would go beyond the WR rating but I didn’t think it would be that much. Now I’m curious if applies to just their resin cases or if the metal cases (A1000 series) would perform similarly.

I don t think that every push of the lever equals to 2m as being a constant in this experiment. It may be that with the rising preassure, every lever push would provide less and less additional preassure as the air density inside the glass chamber rises. You should have used an actual gage with sufficient measuring capabilities for your experiment. On the other hand is clear that the little Casio behaved admirably and got well beyond its rating. But i don t think the high depth numbers are accurate in this experiment, unfortunately. I m 90% sure that the rate of preasure increasing per one lever pull is not a constant variable. Good luck!

The only reason the "beep" stopped when u took the back off was because the lil round thing that looks like a sticker on the inside of the case IS the beep "speaker."
