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.
Now, you can control your Apple Watch by tapping on the image like you would the Apple watch. You can also press the crown and side button, as well as drag your finger up and down over the crown to scroll.
Select the “x” in the corner to close Apple Watch Mirroring.
That’s how you control your Apple Watch from your iPhone.
