Apple Watch 7 Solar Face Inaccurate

The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.

I am having nearly the same issue. It is stating my sunrise time in EST is 4:18 which is 3 hours off. If I turn off location services for the watch face it moves within about 6 minutes of being correct. That however creates a new problem and makes my watch think it just rose a little bit ago even though its nearly noon right now.
