What Does the Label, Water-Resistant, Really Mean When It Comes to Watches?

For athletes or for more active people, they want to have a digital watch that they can rely on. And, because they move their bodies quite a lot, they are also going to sweat a lot as a result.
That being said, if you are an athlete, you might be thinking of getting a waterproof watch for yourself that is sturdy enough to withstand the rigors of a marathon or a triathlon.
To tell you the truth, waterproof watches are actually banned a couple of years ago. That is because it is false advertising, especially since no watchmaker was able to create a watch that can withstand water pressure in the deeper depths of the sea.
However, you can find watches out there that are water-resistant and followed by a certain number to go along with it. What does that exactly mean?
In today’s article, I will talk about everything that you need to know about water-resistant watches and what do those numbers really mean.

Why Waterproof Watches Were Phased Out

There was a time where you can find ‘waterproof’ watches on the market, but that was actually banned by the International Organization for Standardization or ISO since that word is actually quite misleading.
You see, when you go deeper into the depths of the ocean, the water pressure actually rises. And, no watch manufacturer was able to build something that can withstand that much water pressure and, thus, the organization wants watchmakers to scrap that moniker from the watches that they are selling.
Now, this is not to say that there are no watches that cannot withstand the pressure underwater, but this is to say that no watch is fallible, especially when it is submerged for quite a long time.
That is why water-resistant watches were made as a good replacement of the watches of old and they are actually pretty good since you cannot release one in the market without it being tested first.



How Water-Resistant Watches Are Tested

First and foremost, you might see the word BAR that is usually preceded by a number. For instance, 10 BAR or 10-BAR. Well, the word ‘BAR’ is actually just a representation of the atmosphere and the higher the number that precedes it, the deeper it can go underwater without getting water damage. There are also watches that would straight up tell you how resistant they are from water by up to a couple of meters.
Anyway, if you see a watch that is 100-meter water-resistant, it could withstand the pressure underwater of about 100 meters down there, at least, theoretically.
The ISO tests these watches in controlled environments and the watches that you can find that are ‘xx’ meters water-resistant is just simulated water pressure.
Keep in mind that the pressure underwater is subject to change depending on a number of different factors. So if anything, the water-resistance of a watch that you can find on its label is just representative of what it ‘could’ withstand but not actually what it can withstand in real-world scenarios.
