Just when I thought I discovered all the best Apple Watch hidden features, I found a stellar — and I literally mean stellar — tool while changing my Apple Watch face. I think those who are interested in the planets of our solar system will absolutely love this little hack.
If you know how to use the Apple Watch, you probably have figured out how to change your Apple Watch face. Maybe you even know how to use a photo as an Apple Watch face. But have you explored the Astronomy watch face yet?
Though the original Astronomy watch face debuted with the first-generation Apple Watch, it received a refresh with watchOS 9 alongside the Apple Watch Series 8 launch. All of the new watchOS 9 watch faces are interactive in some way or another, but the Astronomy watch face has a particularly cool feature.
The default view of the Astronomy watch face displays Earth, pinpointing your current location along with live cloud coverage. When you edit the watch face, you'll also get the choice of Moon and Solar System views. You'll need to enable Solar System views to see this hidden feature.
Once the Solar System view is saved as your watch face, simply turn the digital crown in either direction and you'll see alignment of all 8 planets in orbit with the sun at the center. You can scroll several years in the past or future to see how the planets were aligned in orbit before, or how they will be aligned one day.
While this isn't really answer to see the next time Mercury will be in retrograde, it is a fun way to explore the solar system from your wrist. At the very least, it makes for a clever party trick, as I'm guessing most people don't know about this feature.
How to get the Apple Watch Astronomy watch face
1. Long press on your watch face.
2. Swipe to the left until you see the plus (+) icon and tap the icon
3. Scroll down to the Astronomy watch face and press add. The faces are listed in alphabetical order so it's towards the top.
4. Swipe to the View option in the customization menu and scroll down to select Solar System.
5. Press the digital crown twice see your new watch face in action.
This feature looks awesome on the Apple Watch Ultra's large screen, but it works with any Apple Watch updated to watchOS 9, including the Apple Watch SE (2022) and select older watches.
