The large black and blue Garmin 010-01241-00 Forerunner 15 is a wrist-worn watch that captures statistics from your run like time, distance, and pace. It can also record your heart rate and heart rate zone if you pair it with a separately sold heart rate strap. The watch reminds you when it's time to move. It also has a rechargeable battery that lasts up to eight hours when using it with GPS on your outdoor runs, or up to five weeks if you keep it in watch/activity tracking mode. Plus, with Garmin Connect you can save, plan, and share your activities with an online fitness community.
