What does 5 ATM water resistant mean?
Water resistance is measured at a static or motionless state.
ATM or “atmospheres” is the amount of pressure a band can withstand. 5ATM will withstand pressures equivalent to about 50 meters, or 164 ft under water. It is important to note that this is a measure of pressure NOT depth. 5ATM doesn’t mean the band can be used diving to a depth of 50 meters.
