Hi JustSYRC,
If you haven't done so yet, restart your iPhone and Apple Watch. Although simple, this step can help correct some unexpected issues. If the issue persists, pair your devices before updating the Apple Watch. Before pairing, make sure your iPhone is running the most recent iOS version, as this may aid in pairing your devices: Apple security updates. If an update is available for your iPhone, be sure to create a backup before installing it.
After your Apple Watch and iPhone are paired, try to update your Apple Watch again.
If needed, this article has the steps that will help with getting your devices paired: Set up and pair your Apple Watch with iPhone.
Turn on, pair, and set up your Apple Watch
1. Put your Apple Watch on your wrist. Adjust the band or choose a band size so your Apple Watch fits closely but comfortably on your wrist.
For information about changing the band on your Apple Watch, see Remove, change, and fasten Apple Watch bands.
2. To turn on your Apple Watch, press and hold the side button until you see the Apple logo.
3. Bring your iPhone near your Apple Watch, wait for the Apple Watch pairing screen to appear on your iPhone, then tap Continue.
Or open the Apple Watch app on your iPhone, then tap Pair New Watch.
4. Tap Set Up for Myself.
5. When prompted, position your iPhone so that your Apple Watch appears in the viewfinder in the Apple Watch app. This pairs the two devices.
6. Tap Set Up Apple Watch, then follow the instructions on your iPhone and Apple Watch to finish setup.
