Apple Watch Series 3 42mm Smart Watch GPS - Space Gray Aluminum/Black

The Apple Watch Series 3 helps you stay connected as well as keep a track of your health. Its built-in GPS records the distance, speed and route of your outdoor workouts. The altimeter tracks elevation during your hilliest rides and highest climbs. Apple Watch Series 3 is swim-proof and tracks both pool and open water workouts. After you are done, sound vibrations eject water from the speaker. It measures your heart rate throughout the day, while you are resting, walking or in the recovery phase after a workout. The Heart Rate app also notifies you if your heart rate rises above a set threshold when you have been inactive for a 10-minute period. It connects to your iPhone via Bluetooth 4.2 connectivity.
