My watch is locked, won’t connect to Bluetooth and is now unpaired from my iPhone and still locked!! How do I fix this?

Watch somehow got disconnected from iPhones Bluetooth! Couldn’t get it reconnected! I went in and “unpaired” watch. Watch was locked until I unlock iPhone but since I couldn’t connect it I couldn’t unlock the watch. Now it’s still locked, acting as it’s paired and my iPhone can’t pair to it again. How can I unlock watch with opening the iPhone when it’s not paired/connected to iPhone any longer?
