A pocket watch (or fob watch) is a watch that is made to be carried in a pocket. Watches were also mounted on a short leather strap or fob, when a long chain would have been cumbersome or likely to catch on things. This fob could also provide a protective flap over their face. Watch chains were introduced about 100 years after pocket watches first appeared in the 16th century.
