Watch

A watch, or chronometer, (AUDIO: Time of the Vulpreen) was a portable device for keeping time. They were used by humans, Time Lords and other species, and included variations such as pocket watches and wrist watches. 21st century watches required a change of battery every so often, which Jilly Kitzinger often forgot to do, (TV: Rendition) while in the 28th century, they were "self winding", requiring only a flick of the wrist. (TV: The Sensorites)

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.
