Since Wear OS 3.0 was introduced, Google has not stopped trying to make it the best operating system for Android wearables as an alternative to watchOS. Most recently, Google may introduce a quick way to set a new watch face after it is installed.
On the Play Store, if you download a watch face, there will now be an option to try it out or after installing you can press to continue playing. The concept has been more or less introduced for Wear OS smartwatches. Where, after a new watch face is downloaded, users can now press to use it as the default watch face on the watch.
This feature is also said to be possible even if the watch is not near the smartphone. After downloading and pressing Set as watch face, it will continue to be automatically set on your watch when it starts to be near the device. This feature is still in the testing stage and it is not certain when it will be introduced to the public.
