Apple Watch is not working properly I have to push in side button every time to unlock to see the time

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.

Go to the Control Center by tapping on the side button (the flat oval one next to the Digital Crown). Look for the icon that hows two theatre masks. If it is highlighted, tap it to turn off theatre mode.

What happens if you swipe up from the bottom of the screen? Does the Control Center come up?

Is the screen black or what exactly are you seeing when you look at your Watch?

I see great minds think alike. 😀

I'm honored to be in such good company. ;-)
