Hey there Leache,
Thanks for reaching out to the Apple Support Communities!
To begin, it sounds like your Apple Watch was updating when it was removed from the charger. We'd like to have you check if you can complete that process by placing your Apple Watch back on the charger and placing it next to your iPhone. Our steps here can help with this: Update your Apple Watch
While force restarting does seem to be a good next step normally, it is not a step that should be performed while the Apple Watch is completing an update. We will need to wait for the update to complete.
If your Apple Watch doesn't appear to be updating any longer, we can then move forward with a force restart with the following steps: How to restart your Apple Watch
"To force restart your Apple Watch, press and hold both the side button and Digital Crown for at least 10 seconds, then release both buttons when you see the Apple logo."
From there, if you still are unable to regain access to your Apple Watch, requesting service is the next best step. The Apple Watch is mailed in for service, even if you visit a local Apple Store or Apple Authorized Service Provider, and our teams can set up a mail in service option in most regions.
