With the Apple Watch series 3, can you swim with it on?

With the Apple Watch series 3, can you swim with it on? I like to various swimming exercises but I don’t want to risk it. I know it says 50 meters and this is just 5-6 feet but I just want to make sure that spending 30 minutes-1 hour at a time wouldn’t damage it
