Understanding watch water resistance ratings is essential for protecting your timepiece. Whether you're dealing with rain, washing hands, or diving, different ratings serve different purposes.
30m / 3ATM: Splash-resistant only (hand-washing, rain)
50m / 5ATM: Safe for short showers and light swimming
100m / 10ATM: Suitable for swimming and snorkeling
200m+ / 20ATM: Best for diving and water sports
Pro tip: Water resistance is not permanent. Gaskets can wear out—have your watch tested yearly if regularly exposed to water.
