Water resistance: 200M/20ATM
Watches marked with water tightness 200M/20ATM are designed for swimming, snorkeling, and for diving with breathing apparatus. 200M/20ATM indicates the degree of water resistance standardized by ISO 6425. ISO tests include temperature changes, depth, pressure (water and air) for different times under rest and during manipulation with the operative part of the watch. The dive models, subsequently performs the test of resistance to salt water and the ability to cope with the watch positive pressure (decompression simulation).
