If your Apple Watch SE fails to update because your iPhone is running iOS 27 while the watch is stuck or incompatible, try this

  1. Place your Apple Watch on its charger and make sure it has at least 50% battery.
  2. On your Apple Watch itself (not the iPhone), open Settings > General > Storage.
  3. Locate the corrupted or stuck watchOS update file and delete it.
  4. Restart both your Apple Watch and your iPhone.
  5. Go directly to Settings > General > Software Update on your Apple Watch while connected to Wi-Fi to run the update.

The Apple Watch SE 2nd generation is not compatible with watchOS 27.
