The frequency of the quartz crystal is obviously a fundamental specification. It is normally expressed to as many significant figures as demanded by the frequency tolerance, although seven figures is normally the maximum. It is wise to express the frequency to the right number of significant figures to avoid misunderstandings in this area of the quartz crystal specification.
