iPhone at home when you go for a run or ride — and still measure your workout accurately. You can also do swim workouts in open water, track laps at the pool, or splash with your kids. And with the brightest display Apple has ever made, you’ll see your metrics clearly, no matter how much the sun glares. Water Resistant: Splash. Surf. Swim. Apple Watch Series 2 is rated water resistant 50 meters,1 so you can leave it on when you’re in the pool, the ocean, or even a hot tub. Since a speaker can’t be sealed because it needs air to produce sound, we reinvented ours — it lets water in, then uses sound vibrations to force it back out.
