Morphology
This noun–noun combination is directly compositional: 'watch' (a period/team assigned to guard) + 'fire' (a burning flame) yields a fire associated with or maintained for the watch (i.e., a signal/guard fire). The relation follows a predictable English compound pattern and would be understandable to a B1 learner who knows both constituent meanings, even if the term is somewhat literary or historical.
Etymology
Watch fire comes from the simple picture of guards lighting a fire on a hill so people could watch it from far away; the bright fire was a signal to warn others or call for help. That's why watch fire means 'a fire lit and kept burning at night to serve as a signal'.
