Amazfit Cor Heart Rate, Activity & Sleep Tracker

An activity tracker, a stopwatch, an alarm, a heart-rate monitor, a sleep tracker, and much more: The Cor gives you loads of functionality without the hefty price tag. Made of 2.5d Corning Gorilla glass, it features a colorful 1.23-inch LCD touch display. An integrated three-axis accelerator and an array of sensors help it keep track of routes, pace, cadence, distance, time, and heart rate—to name a few. Whether you’re running indoors, walking through the neighborhood, or riding your bike, the watch has preprogrammed metrics that provide you with activity-specific information. Since it’s waterproof down to 5 ATM, there’s no need to take it off before a dip, either. The lithium-polymer battery lasts up to 12 days with regular use. To keep you connected, the watch displays notifications for incoming calls, messages, and emails, too.
