It looks like an interpretation of the Master's pocket watch from the Doctor Who episode "Utopia" [3.11].
Cool! I was wondering.
I ordered one or my mother, but I wondered if it was an obvious enough reference that she might recognize it.
If she's a major fan of the show, she'll definitely pick up on the reference. Otherwise, she'll probably just love having a pocket watch/necklace that has a Gallifreyan design on it.
