The First, Seventh, Eighth and Eleventh Doctors all regularly wore and used fob watches. The Eleventh Doctor began to regularly wear a watch chain after going into retirement and continued wearing it after his return, when he changed his clothing style. (TV: The Bells of Saint John) It was generally a gold fob watch fastened to his waistcoats. (TV: The Day of the Doctor, The Time of the Doctor) The fob watch carried by the Seventh Doctor was the one used by the First Doctor. (PROSE: All-Consuming Fire)
