Water resistance: 50M/5ATM

Watches marked with water tightness 50M/5ATM are designed for incidental contact with water (car wash, rain), but also for surface swimming without diving. 50M/5ATM indicates the degree of water resistance standardized by ISO 2281. 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.
