watchOS 8.5.1 Now Available to Download for Your Apple Watch
According to Apple, the update features bug fixes and security updates.
The update can be downloaded now through the companion Watch app on your iPhone by heading to General > Software Update in the My Watch portion of the app. You can also go to Settings > General > Software Update on an Apple Watch.
Your watch needs to have more than 50 percent power and connected to a charger. Like most Apple Watch updates, it could take anywhere from 30 minutes to an hour to complete, so be patient.
It’s compatible with the Apple Watch Series 3 and later.
