Apple Watch Series 5 won't update Even Though iPhone is updated

I updated my iPhone X to 16.7.1, the latest version available. I then tried to update my Apple Watch Series 5 (to 10.0 or 10.1) and it said I need to update my iPhone first. Well I've done that so not sure how to fix this so I can update my watch. Thanks in advance for your suggestions.

Apple Watch Series 5, watchOS 9

Hi Elliot-Chicago,


We'll be happy to help by explaining why you are still seeing the message to update your iPhone.


In order to upgrade your Apple Watch to watchOS 10, your iPhone is going to need to be upgraded to iOS 17. However, an iPhone X is not compatible with iOS 17, as shown here:

The software version watchOS 10 is not compatible with iOS 16. For details about the new watchOS 10, go to watchOS 10 - Apple.


Let us know if you have any questions.



Take care!
