Limited Backwards Compatibility
Apple does its best to bring its operating system updates to as many of its devices as possible. At some point, it is not practical to roll out an update because of hardware limitations and performance issues. Such is the case for Apple Watch Series 2. According to The Verifier, Apple will not include the Series 2 Apple Watch when it releases watchOS 7. The device reportedly is too slow to run the latest version of watchOS reliably. Apple will continue to update the second-generation with minor updates and bug fixes for one more year.
