Sunset / sunrise Apple Watch not working.

Doesn't work for me, no location services.

I restarted and it solved only for a while. than it vanished again.

Thank you for this response, I had tried other methods on here, none of which worked so was delighted to fix it using your instructions 👍🏼

This worked on mine. Thank you!!!

Something for me. World clock won’t allow me to change

Thank you so much! Ive had this issue for so long and it’s finally fixed. Thank you thank you thank youuuu!!!

None of the other fixes (changing options for location services, or changing data sources) worked, but this fixed it immediately.

Thank you so much!!! This worked on my Ultra :)

This worked for me. Thanks

Is setting on iPhone or Apple Watch

This worked for me... Series 9, watchOS 10.4.

On iPhone, go to Settings --> Privacy & Security --> Location Services --> make sure Location Services are turned on --> Clock --> make sure both While Using the App and Precice Location are selected.

After getting a new watch, Precise Location was off by default. Turning it on fixed the problem.

Been having this same issue since at least WatchOS 10.4. Tried all of the suggestions, and nothing worked for me. I have two watches, and it wasn’t working on either.

Just poked around, and here is what seems to have worked for me so far…

Open Watch app on your iPhone.

Swipe down to and tap “Clock”

Scroll all the way down to “Siri Face Data Sources”

Tap this

Scroll to “Sunrise/Sunset”

Set the slider to on, if it is not already,

or

set it to off, back out of this screen, and set it to on again.

Mine was already set to “On” (green), so I set it off, backed out, went back in the same screen, set it on.

I immediately got the sunset time on my Infograph face.

Your mileage may vary…
