Water resistance is a frequently discussed issue in watches. We often see three related labels on watches: ATM (Atmoster), Bar (Meter), and WR (Water Resistant). Let's delve into the details...
In fact, we shouldn't give too much weight to every meter we see on a watch. For example, if we see 5 bars, this means 50 meters, but it's not the exact 50 meters we think it is. We can define the term "bar" as the pressure measurement at which the watch will operate underwater. Therefore, we can change our perspective. ATM actually means atmosphere. This, again, is related to pressure. Don't try diving with your watch based on these measurements. 😄
So what do these meters and bars mean and where can we use them?
G-Shock has published a table on their blog about this, which can be considered a prediction. However, in summary, watches with a WR (wind) value of 30-50m should not be used for activities such as swimming in the sea or pool. Even those with a 100m rating can be dangerous for these activities. Furthermore, if your watch doesn't have a locked crown, it's still at risk. Therefore, choosing the right watch for your swimming needs is important. I'm sure none of us dive to 200m, but if you're doing healthy diving and water activities, 200m will be the safest option for you. These watches are generally... Diver You might see the phrase "bar pressure". The purpose of these types of watches is entirely based on this. There are watches that show values like 600m-1000m. Actually, the table below will be a good resource for us. In dress watches, which are watches worn with suits, you usually see 3 bar pressure. More than that is not necessary anyway. Not letting water in while washing your hands is one of them. dress watches That will be sufficient. Therefore, the types mentioned here are also important when buying a watch.
Bonuses
- For a watch to be considered a true diver's watch, it must hold ISO 6425 certification. However, not every brand chooses to submit to this test. However, we can say that this certification is specifically designed for diver's watches.
- Another detail you'll find in professional diver's watches is the Helium Escape Valve. It's essentially an escape valve. Professional and scuba divers are exposed to high pressure when underwater for extended periods. If you're wearing a watch with this feature during this pressure, it's a feature that helps release the gas inside when you emerge. In short, it's a feature that helps prevent damage to the watch.
- After using your watch in salt water, rinse it with plain water. Leaving salt water on the steel will damage it.
My own experiences
Non-locking peak Seiko 5I actively swam in the sea with my (SRPD59K) for about 4-5 days. I didn't encounter any problems. It was a bit of a daring move on my part, but even so, I didn't experience any issues. But don't take my advice and risk it too much! 😁
