Galaxy Watch, Watch Active3, and Watch3 are all rated 5ATM as well as IP68, meaning that they are water resistant and resistant to water pressure at a depth of up to 50 meters. So you can not only wear it safely in the rain or while taking a shower, you can use it to track your workouts while you're swimming.
