The man slipped a long dark iron knife, almost a short sword, from his belt, and after breathing on it, handed it hilt-first to Puck, who took it with his head on one side, as you should when you look at the works of a watch, squinted down the dark blade, and very delicately rubbed his forefinger from the point to the hilt.
This is from "Rewards and Fairies" "The Knife and Naked Chalk Hill" http://pinkmonkey.com/dl/library1/digi300.pdf
I can't understand the meaning of " the works of a watch " Is this just the movement of a watch?
I am glad if some one kindly teach me.
