Track your runs with GPS and an altimeter. Wirelessly pair your watch with compatible devices at the gym. The Apple Watch Nike+ features a swim-proof design, allowing you to jump straight into the pool after your run. With built-in cellular, you can stream your favorite music and receive calls, messages, and notifications—even when you don’t have your phone with you. There are new Nike watch faces and bands: the Nike Sport Band with molded perforations for better ventilation and the Nike Sport Loop, which incorporates a special reflective thread.
