Unable to fully remove pairing on apple watch

Kept having unlocking problems with my series 3 hence I decided to just unpair then pairing it again. Managed to unpair it using the Watch app/ remove it from my Apple ID devices but my watch is still locked and seems like my stuff are all still in there, even after I've tried to hard reset etc.

So right now I'm locked out of my watch, I can't unlock it because I had the "Unlock using iPhone" feature as activation lock but since my Iphone no longer has my watch as a pairing, I don't know how to solve this.

Any help is appreciated, thank you!
