On your iPhone, go to Settings > General > iPhone Storage and delete anything there that looks related to watchOS. Then open the Watch app and begin the Software Update process.

If what you see is the same as your original post, try choosing “Close” then see if you can open the Watch app and restart the update process.

Neither. You found the Watch app, not watchOS.
Please post a screenshot of what you see when you open the Watch app and go to My Watch > General > Software Update. Thank you.

watchOS 27 was released by Apple on September 14, 2026. You should not attempt to install a prior watchOS version.

watch app is only trying to install 26.6. How to enforce the app to install 27?

I see this. Should I delete the watch app and reinstall? Or offload app or remove all backups?
