A watch was a portable device for keeping time. They were used by humans, Time Lords and other species. 21st century watches required a change of battery every so often, which Jilly Kitzinger often forgot to do. (TV: Rendition)
Uses of watches Edit
The Ninth Doctor wore a wrist watch. (TV: Rose, The End of the World) The Doctor's TARDIS homed in on it when Sally Sparrow hit the TARDIS' reset button. (PROSE: What I Did on My Christmas Holidays by Sally Sparrow)
Both the Tenth Doctor and the Master used a biodata module shaped like a fob watch to contain their respective Time Lord consciousnesses while they were temporarily made human. (TV: Human Nature / The Family of Blood, Utopia)
Watches could have sentimental value. As part of a Muslim tradition during their wedding, Prem gave his wife Umbreen his watch. He dropped it passing to her, shattering the face. Umbreen's mother Hasna declared this to be a bad omen, but Umbreen said it recorded the very moment she married her husband. Though her husband died on their wedding day, Umbreen kept the watch for the rest of her life and insisted it was never to be fixed.
On her birthday in 2018, Umbreen gave the watch to her granddaughter Yasmin. As Yaz wanted to know more about Umbreen's personal history, the Thirteenth Doctor used the watch to establish a telepathic link between her TARDIS and 1947, where the Doctor and her companions watched the events of Umbreen's first wedding unfold. (TV: Demons of the Punjab)
Early in her travels aboard the TARDIS, Erimem — who came from ancient Egypt where watches had not yet been invented — once expressed shock that Peri could promise to check for the Fifth Doctor's return "every twenty minutes". Peri temporarily traded on her friend's ignorance by suggesting that she had "talent" and a "special device" called "a watch". Being new to the technology, Erimem was genuinely interested in this revelation, but the Fifth Doctor chided Peri by saying that she was "in a very difficult mood". (AUDIO: Nekromanteia)
