Apple Watch Series 2 Is ‘Swim-Proof’ | NBC News By NBC News

We call it Apple Watch Series ? and it has been completely re-engineered, and it starts with a feature that will change how you use Apple Watch. The first Apple Watch was splash proof, an Apple Watch Series. ? is swim proof, so you can wear it whether you're swimming or surfing, or just doing that occasional cannonball. You can keep it on it's rated water-resistant 50 meters, which is the industry standard for a swim watch. But what that means is the watch needs to withstand the pressure, the water pressure equivalent of being at a depth of 50 meters and that's pretty deep, and it's especially challenging for a Smartwatch, because there are so many ingress points. So our engineers have been hard at work.

Developing new seals and adhesives, and they've been able to close all those entry points except one. The speaker, you see a speaker needs air to produce sound and if the air can get in soak in the water and that's a problem so for series 2, we redesign the speaker system and, at the end of your workout, we use the speaker itself to eject the water. We also wanted to make sure Apple Watch was robust enough, not just for an occasional swim, but for people who want to swim every day. So we built a simulator to test the effects of swimming over multiple years. We rerun, watches in here we put watches in there from 24 hours a day for weeks at a time simulating hundreds of thousands of strobe.

So you can wear your watch with confidence in the water we've also extended. The work of our fitness lab to swimming now, calculating calorie burn for swimming is, is really tricky, and we've analyzed over 700 swimmers, different body types, different abilities, we've hooked them up to state-of-the-art metabolic equipment, we've even drawn blood samples to look at lactic acid levels, and we used all this body of information to create an algorithm that will give you the most accurate calorie burn information while you're swimming we've created two new workouts, a pool swim and an open water swim and during the workout you'll get information like lap count, pace, distance calorie burn, but what's more, the watch will learn about you over time and will get more accurate over time. It looks at your individual stroke efficiency, not that of some average swimmer and tailors just to you.
