What is ATM for water resistance?
What is ATM for water resistance?
Water resistance is stated as a depth ( ATM or Meters ) this means that it has been tested in a laboratory to with stand a static pressure for a short period only at the stated depth. The actual water pressure on the watch during use is greater than the static pressure.
Which is better IP68 or 5ATM?
Clearly a water resistance of 5ATM is going to be better than IP68. Even though, in the case of IP68, you may not know how much further than a meter the watch is resistant, more than likely it won’t be too much. And it most probably won’t exceed 50 meters!
What does ATM water mean?
ATMOSPHERE
ATM is simply an abbreviation of the word ATMOSPHERE and this relates the the amount of pressure a watch is designed to endure, pressure increases the deeper you go underwater. On our website, we group watches into 3 categories of water resistance these are; splash-proof, waterproof and dive.
How deep can you go with a 5 ATM watch?
50 meters
Water Rating Definitions
| Water Rating | Definition |
|---|---|
| 1 ATM | Withstands pressures equivalent to a depth of 10 meters |
| 3 ATM | Withstands pressures equivalent to a depth of 30 meters |
| 5 ATM, Swim | Withstands pressures equivalent to a depth of 50 meters |
| 10 ATM | Withstands pressures equivalent to a depth of 100 meters |
Can I swim with a 3 ATM watch?
3 ATM = limited waterproof, splash-proof: The watch is protected from splashes such as rain, must not be immersed in water, and must not be used in swimming or sauna. 5 ATM = limited waterproof: The watch can be used in humid conditions, eg in surface water. In principle, you can swim, but it is not recommended.
What does 10 ATM water resistance mean?
1 bar corresponds approximately to the air pressure on the surface of the earth or a water column of 10 meters height. 10 ATM corresponds to about 10 bar, which is approximately the pressure that prevails at a depth of 100 meters. This is where the term “100 meter water resistant” comes from.
