Doctor's TARDIS Tracker Wristwatch

A specialized wristwatch device belonging to the Doctor, used to locate and track the TARDIS by homing in on its signal. In the UNIT laboratory, the Doctor activates the watch, which emits a steady beep to pinpoint the TARDIS's location despite his amnesia. Brigadier Lethbridge-Stewart, Liz Shaw, and security personnel observe as the device confirms the ship's proximity within UNIT HQ. The watch's precise functionality underscores the Doctor's unique bond to his ship and serves as a critical tool for identity verification and TARDIS recovery in tense situations.
