Hello :)

Since you’ve already tried restarting, resetting the network, resetting and unpairing, try deleting the downloaded watchOS update before downloading it again:

Watch app -> General -> Storage -> find the watchOS update -> Delete Update, then go back to General → Software Update and download it again.

Apple specifically recommends this when a Watch update won’t install. Keep the Watch on its charger and the iPhone on Wi-Fi during the update.
