For everyone experiencing iOS connectivity issues, give this a try. I thought I’d try once again resetting the phone back to factory and starting over, but I ended up back in the same boat (no connection), or the process got stuck on the phone sending details to the watch.
I tried a mountain of things (over 2 hours messing about), and eventually (touch wood), this has worked:
On the Wear OS app (or Android Wear if not updated), in advanced settings, click on disconnect Tag Heuer. This should disconnect your watch and kick it into a factory restore status.
Whilst the watch is loading, open up your settings and click Bluetooth. Click the little “I” next to the Tag Heuer entry and forget the device.
Now make sure you then update to the latest iOS version (currently iOS 11.3).
Physically remove the Wear OS/Android Wear app from your phone (don’t just update, it doesn’t work properly. When I deleted my app and downloaded again, I got a brand new interface, even though the previous version said it was the latest one).
Reboot phone.
Re-download the Wear OS app from the App Store.
Back to the watch now which should have restored. Select your language and basic options then when prompted, open up the Wear OS app on your phone and follow the prompts until your phone has paired and your Google account details have been sent across (mine failed 3 times at this point whilst doing various other tasks, but I’m assuming if you follow the process as above, this should work first time).
When all ready, ensure you open the Play Store on your watch, swipe down and select my apps.
Update any which need updating. Check that the following list of apps are now installed and fully updated on your phone, if any are missing, download them:
Connected Tag Heuer
Google
Google Fit
Google Pay
Tag Heuer Connected Apps
Wear OS by Google smartwatch
Google handwriting input
Now check to see if your watch is connected to your phone and everything is working as intended.
Good Luck !!
