A pocket watch was a device used for timekeeping in the 19th century.

In 1845, the DeLorean time machine's keys were attached to a pocket watch. It is unclear, however, if this may have been an effect of the clothing converter trying to find a suitable object to disguise them as.

In 1955, Emmett Brown had a pocket watch, as well as two other wristwatches that he wore on each hand. He checked the time on his pocket watch while waiting for Marty to arrive at Courthouse Square.
