Always measure your heart rate. This smartwatch features a heart rate monitor, allowing you to check your heart rate at any time. This luxury smartwatch has an aluminum case. This material is sturdy and lightweight, and it looks great too! With this smartwatch, you can read incoming notifications directly on the watch display. It's ideal because you no longer need to reach for your phone.
Enjoy even better sleep. Track your sleep and receive feedback on your sleep quality. See when your REM, light, and deep sleep occur during the night.
