Artwork in Friends episode?

In Season 10 of the television series Friends, there is artwork in Ross's office that I am interested in learning more about. In the episode "The one with Ross's Grant," there is a point in the episode when Ross is in his office and the guest character for the episode comes into his office the apologize for earlier behavior. Behind him on the wall is a piece of art that is a pocket watch with a yellow face that has what looks like extra hour and minute hands floating around it. Any suggestions would help!!!!
