HI,
the correct time is not updating on the sunrise/sunset complication
I tried all the below , even unpaired it
On the paired iPhone, open Settings and go for Privacy & Security.
Tap Location Services and enable them if they’re not already on.
Go for Apple Watch Faces.
Select While Using the App
If that doesn't work, try setting up the complication again.
Go to the Watch app
Tap on the Watch Face under My Faces
Change the complication for the top right to something else.
Then change it back to Sunrise/Sunset
