Apple Watch screen mirroring allows you to view your Apple Watch’s screen and control your Apple Watch via your iPhone.
Note: Keep in mind that these controls can be a bit finicky, and if you’re continually failing to engage a specific function, it may be that feature is not yet available for Apple Watch Mirroring.
The first thing you want to do to mirror your Apple Watch on your iPhone is open Settings.
Scroll down to Accessibility.
Select Apple Watch Mirroring.
Toggle on Apple Watch Mirroring. It will be green and to the right when enabled. A live image of your Apple Watch will appear on the screen.
