Check out my shorts to see the test done by holding it up in the air, pressurizing the tank and then lowering it into the water to look for bubbles. Future videos the test will be performed this way. Hopefully this still shows the ability of the watch regardless! Thanks everyone!

One specific thing you did not mention about ISO 6425 is that this standard requires every single watch that is being produced, to be pressure tested up to the rated depth + 25% and remain at that pressure for 2 hours. After that test, a condensation test must be performed to check for water ingress. This means that if you buy a watch that has "DIVERS 200 m" on the dial, that that very watch has been at a pressure equivalent to the rated depth + 25%. I am glad that you debunked the myths about water resistance.

I think the minimal water resistance rating on the basic Casios is partly because you're not supposed to operate the buttons under water. But I believe you can do so on the basic G-Shock square DW5600. That's a $50 watch that does almost everything, and you can drag it through hell. On the low end, I prefer the F105 to the F91 because of the EL backlight, which is like Timex Indiglo. Similarly, in stainless (with a metal plated resin case), I like the A168 better than the A158 for the same reason. Overall, it's incredible how good these are for the money.

Why is that the methodology? My guess is one might assume it’s more realistic because on a dive you’d start in air then go to water. But in this tank isn’t the air at the same pressure as the water, which is of course unlike real life? Am I misunderstanding something?

I think it was 1971 when watch makers had to stop calling their watches waterproof and instead say water resistant. You will often find vintage watches from the early 70's where the case back will say water resistant but the dial will say say waterproof. This is because the dial was made before the date of the change. Most diver type watches will state the minimum water resistance and rarely the maximum. The Vostok Amphibia has a 200m water resistant rating but has achieved twice that. 👍

funny thing is that I used to snorkel-dive with a swatch all thru the 1980's to depths of about 15 feet. This is what most recreational watches go thru. I never had a leak. Fast-forward to recent times and manufacturers tell usthat the same "30M" rating is only good for "splashing". Shows that these companies lowered standards to what they wanted to, to achieve cost-savings and reduce liability. As a side note, the author of this video is quoting the "new" ISO rating that came out 12 years ago and is optional (ISO22810). Most companies still use the older 30-100-200 ratings that had the "splash"/"Swim"/Dive levels.

I swim in it in salt water (rinse it later), I wear it in a pouring rain, and in any other inclement weather that Florida can throw at me. Zero problems.

Thanks for the video. I have one of these Casio watches, along with a number of diver's watches. I consider it the 'coolest' watch in the connection. 👍 Maybe other comments have covered this, but in case anyone is thinking of using one of these pressure testing chambers with their watch, this isn't the way to use them. I realise that for this video the watch is cheap and can be replaced easily. But the way to use this device is to hang the watch in the air space above the water, then increase the pressure. If the watch isn't sealed properly or the gasket needs replacing, only air will enter the watch. Then you release the pressure and lower the watch into the water at the same time. The air at higher pressure inside the watch then starts to escape, and you will see bubbles coming out of it where the seal is compromised. This means that the watch could be re-sealed or repaired but no water got in to ruin the movement inside. Even very expensive watches can require a new gasket at times, especially after battery replacement or servicing. It would be an expensive mistake to allow water to get into the watch. Thanks again for the video.

Very well explained, I don't think most people understand how deep 100 meters is. 99% of the time is someone's watch is deeper than 20 feet it's because it fell off of their wrist. This might be a big ask but can you do the pressure test on a Casio "Duro" MDV106? That's probably the most affordable dive watch on the market.

A 50m Field watch will be able to withstand more water than most people will ever encounter. I really appreciate this video.

The cave diver Sheck Exley used to wear Casios on all his dives. I'm not sure if they were f91w's or not, but they were cheap digital Casios. He'd wear two on his wrist and also wrap them around the regs of his staged decompression tanks as backups, but he never had one fail even in extreme technical diving beyond 200m. I dive with a duro or an ISO diver just for easy readability, but I'd have no reservations about diving with an f91w either.

The additional margin you need is in case you strike your watch against a hard surface (scuba tank, rocks, etc). An engineering margin of safety is usually double the max static pressure something might be exposed to. Underwater is a pretty harsh environment and the testing is under idyllic conditions (static temperatures, clean water) so I’d expect the spec to be more conservative.

Great advice for non divers. I am a highly experienced diver, and trained to a very high level by world class professionals. I use housings on the surface and at depth, and the seals are at greatest risk of leaking when at the surface and dunking the housing in a freshwater rinse tank (not recommended). This is because the seals are not under pressure and so are at their least resistant to working. That is why the standards are different for splash and depth. When diving, I may have a dive computer on each wrist of different brands, one of which is wirelessly connected to a tank pressure meter, and a third dive computer physically connected to the tank. All of this is to not get caught out by equipment failure in the wild. In other words, when I dive I have no space to wear a dive watch, so in a watch for me splash resistance is way more important than depth.

I just stumbled across the h20 kalmar 2 Deep Diver. It’s rated at 25,000 meters. Can you test that next please? I’m interested in exploring the bottom of the ocean and I need a watch I can depend on.

Would this hold true of automatic watches from companies such as Seiko who at 3Bar WR actually state not to swim with it?
@meindertsprang7491 25 күн бұрын
Yes. That is exactly what the ISO 22810 standard is all about. If you state 30 m, it should handle 30 m at least.

You’re not using the instrument correctly. You must pressurize the vessel while the watch is above the water. Once pressurized then you lower it into the water. This prevents water from entering the watch if its not water resistant. When you slowly release the pressure bubbles will start coming out of the watch if its not water resistant. At this point lift the watch out of the water and no harm will be done.

Question: if air escapes the watch, isn’t it being replaced by water? Also, is the test in the video a complete bust that negates the conclusion? (lol. Physics is tough for me!)

Bergeon SA has an instructional video on their KZfaq channel. I've seen more than one KZfaqr do it wrong.

@@geoffreydlin8043 The air in the watch is not replaced by water. As soon as you see bubbles coming out, you lift it out of the water. I'd say the video is a bust.

I think I figured it out. When the watch is pressurized through the air, if air squeezes into the case, when it’s immersed into the water and pressure is released, the water is just there to see the air escaping in the form of bubbles.… Right? The water doesn’t do anything except help visualize what’s going on.

@@geoffreydlin8043 Correct! I suppose if you don't lift the watch out of the water in time after depressurizing then you risk water entering the watch.

Harrison, can you please share a link to your water pressure testing device?

Thanks. I always thought that "WR" on a Casio really meant Resist Water.

Great insights. Any idea how long before those ratings diminish due to aging gaskets? 10 years, 20 years, etc..
@HarrisonElmore 26 күн бұрын
Depends on the silicone used and the gasket quality. Also if you swim in salt water they degrade faster.

Watch is a device to measure time . At some point it became jewlery.

People have taken these and i think the a168 or similar to several hunder meters of depth and the survived until the pressure bent the plastic screen so much, the screen broke the module by pressing on it. It never leaked though..

Good video, and accurate for still water, but you should hear in mind that in the sea the force of a wave can exceed 30m static head. Unfortunately I learned this the hard way. You are actually more likely to ruin a watch playing in the surf than diving at depth.
