The step count is fine and good, but the Apple Watch has a number of important emergency and health features that keep you alive and worth using.
The Emergency SOS feature informs people that you are in trouble and where you are, so that someone can come to the rescue. With Show When Locked, important medical conditions can be displayed on your home screen, even if your phone is locked. You can also set up emergency contacts and instruct the phone to detect falls.
Setting Up "Show When Locked"
"Show When Locked" can be important if you are suffering from a chronic condition like diabetes or an allergy that could trigger a health crisis; If you need help, the information is available to others without having to unlock the phone. On your Apple Watch, the information is displayed on a slider that appears when you hold down the side key.

Touch the person icon in the upper-right corner of the summary screen.
Tap "Medical ID" in the "Medical Details" section of the profile screen. When you use the app for the first time, much of the page is filled with a form that contains this information.
