Apple Watch ultra not showing sunrise/sunset time on display

Force Restart Your Watch:

Press and hold BOTH the digital crown AND elongated power buttons at the SAME TIME. Keep holding them both until the screen goes dark and keep holding them until you see the Apple Logo, then let go. Sign back in when prompted and see if the issue is resolved. It will take a few seconds after you sign back in for all complications to update.

You're welcome. I'm sure they'll get it sorted for you. Before you do however, I don't recall either LD or myself asking if your watch is updated to WatchOS 9.2 (the most current WatchOS version)? If no, update your watch. The Force Restart your watch after the update and see is this resolves.

OK.....When you open the Watch app on your iPhone and tap Weather. Is Default City set to Current Location and is Mirror my iPhone checked?

Your watch gets such data from the iPhone Weather App. The official one from Apple. Have you configured the weather app on your iPhone to your local city?

The app you should have on your iPhone and Apple Watch is this:

Yep, you don't have a VPN profile. Do what LD150 suggested and reboot your home router (just unplug it for a minute, then plug it back in). Once it comes back up and your reconnected, hopefully you'll have the complication function as expected whether on Wifi or Cellular.

But is there a VPN profile (connected or not) on your iPhone?

Maybe the Series 7 showed it on OS8 but did the Ultra ever show it?

There was a change when OS9 came in that reduced the information on that complication and has led to some complaints.

Did you try the forced restart on both watches?

That's great. Do you by chance use a VPN on your iPhone? If yes, DELETE it. VPN on iPhone is simply not necessary and can cause way more issues than it could possibly solve. We know your watch is working correctly on cellular. Maybe the connection from your iPhone when on Wifi is an issue.

Oh, you beat me to it lg1! I agree, particularly if the problem returns when wi-Fi is reconnected

I would also reset the router to factory settings and reset network settings on the iphone for good measure,

Then I would recommend contacting Apple Support. It's working flawlessly on my Ultra. If you're in the US, you can call Apple at 800-MY-APPLE

Then, I'll turn you over to Apple for help.
