Bought used watch and the previous owner's Apple ID is attached to it

I bought a used series 4 apple watch. The previous owners apple iD is attached to the watch. I don't have their id to remove the watch. I can't contact the previous owner to do it. Is there anything that I can do to unattach their iD from the watch and pair the watch with my apple iD? Help me please.....I don't want a useless watch
