From Tardis Wiki, the free Doctor Who reference
The scanner watch was a device used by Sarah Jane Smith to detect alien life, and identify the species and its origin. It gave off a humming sound when in use. Superficially, it appeared to be a normal wristwatch, but the face of the watch concealed a scanner screen. Like her sonic lipstick, it was left by the Tenth Doctor for Sarah Jane inside K9.
