There are some native OS X screen savers that I think are pretty cool, but there is no watch option. Yes, there is the option of showing the time on any of the protectors, but we must agree that it is not a very elegant solution.
what comes in Apple Watch Screensaver for OS X, created by Rasmus Nielsen.
The idea is to take the look of one of the Apple Watch displays to your Mac screen saver. To do this, just download the file and double-click it to begin the installation. Just choose whether you want to install just for your OS X user or for everyone, and test everything on System Preferences Table and Screen Protector Screen Protector.
If the protector is successful, Nielsen should add customization options in the future.
It looked pretty, right?
