Gold Pocket Watch Chains

Necklace The Ugly Truth?

Does anyone know anything about the necklace worn by Katherine Heigl in different scenes in the film or something similar? It is a long gold chain itself with what appeared to be a pocket watch on the end – I could not keep eyes off of it throughout the movie!
