On the Go: Faster Connection? No Question

With Apple Watch SE 3, you can keep in touch with the people and things that matter most. Cellular lets you stay connected even when you don’t have your iPhone nearby.[1] And with 5G capability, you can download apps faster and stream music or podcasts at the speed of go go go.[2]

Health: Stay One Beat Ahead

Get meaningful insights about your health, just by wearing your Apple Watch SE 3. An innovative wrist temperature sensor enables deeper insights in the Vitals app and retrospective ovulation estimates in the Cycle Tracking app. You’ll also receive a daily sleep score and possible sleep apnoea notifications. It’s never been easier to live in the know.

Know Your Sleep Score

Sleep quality is influenced by factors such as sleep duration, bed­time consistency, how often you wake up and time spent in each sleep stage. Sleep score analyses these factors every night and provides a classification and a score. You’ll see how the score is calculated, so you can understand the quality of your sleep and learn how to make it more restorative.
