Great condition used smart watch from Garmin. I primarily used this for running, but this watch will also track biking, swimming, golf, walking, and treadmill walking/ running. Features also include getting notifications from your phone and syncing your calendar from your phone. However, you cannot make calls with this watch like you can with a watch from Apple. This will work with Apple and Android. This also includes 8 different color bands that can easily be exchanged with the provided tools.
