The watch should keep time is six positions; if it only keeps good time in one, it should be serviced by someone knowledgeable about pocket watch repair--and believe it or not, that may not be a jeweler.
A well-serviced pocket watch can actually keep more accurate time than a quartz watch (i.e., it will gain or lose time less quickly than a quartz watch).
