What is 5ATM?
5ATM refers to the waterproof depth of the band under standard conditions. Such conditions mean that the band has a certain extent of resistance to water pressure under stationary state. The pressure resistance value is not obtained under water, but based on a conversion of atmospheric pressure. The value of 5ATM indicates that the band can withstand the pressure of 50 meters under water under stationary state (5 atmospheres of pressure, or 5ATM), rather than that it can be used underwater within 50 meters. Notes: 1 standard atmospheric pressure (ATM) = 101.325kPa (KPA).
