With the release of WatchOS 11, Apple stopped supporting software updates for several Apple Watch models. Here are the Apple Watch models that will not get WatchOS 11:
Apple Watch Series 5 (2019)Apple Watch Series 4 (2018) and olderApple Watch SE (2020)
This list only includes the first-generation Apple Watch SE, launched in 2020; the 2022 Apple Watch SE is expected to support WatchOS 11.

Apple typically drops software support for older Apple Watch and devices with hardware limitations to focus and streamline the development process of newer models. Of course, this is also part of tech giants’ market strategy, as it motivates users to buy new devices.
