Motorola MOTO-MOWATCH70BK MOTOROLA MOWATCH70BK

Good quality watch. The battery life is decent, I charge itevery day when I'm in the shower and it's never died on me. It connects to your phone easily, but double check at least weekly that it's syncing. I enjoy using the activity tracker for individual activities, it keeps good track of your speed mi or km per hour, heart rate, etc. I also like that you can switch out the watch face and choose 24 or 12 hr time as well as choose between km and mi. It's a very simple smart watch primarily designed to track exercise. If you want something that does more, you will be disappointed. However if you want something that tracks your sleep (light, deep, rem and time awake), activities, steps, and calories burned than this is perfect!!
