Hi

Check that you are following the instructions here:

Set up your Apple Watch - Apple Support

If your iPhone is already updated to the latest software:

Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support

Then it may help to unpair and re-pair your watch:

• The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app. Choose to Restore from Backup during set up. Most data and settings will be restored, with some exceptions (eg Apple Pay cards, passcode).
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support

To confirm, if you have not yet done so, first update your iPhone to the latest version of iOS 10:

Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support

Also delete any beta profiles (on your iPhone and/or watch) and restart both devices (this only applies if you have ever participated in an Apple Beta Software Program).

If the issue persists, I suggest following these steps:

• Unpair your watch using the Watch app on your iPhone:

  Unpair your Apple Watch and iPhone - Apple Support

• Make an encrypted backup of your iPhone:
  • If using iTunes, be sure to choose the option to Encrypt iPhone backup.

• Restore your iPhone to factory settings using iTunes:

  Use iTunes on your Mac or PC to restore your iPhone, iPad, or iPod to factory settings - Apple Support

• Restore your iPhone from the encrypted backup;

  Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

• Pair your watch, restoring it from backup if offered the option during set up:
