AT-cut quartz-crystal vibrators with the frequencies higher than l MHz have been utilized recently for clocks. The typical frequency is 4194. 340 kHz. The present paper describes the result of a series of experiments which has been made in order to examine what degree of fine polishing is necessary for the practical use of such kind of quartz-crystal elements, from the point of view of their mass production. The quartz-crystal elements examined here are of AT- cut, 4l94. 304 kHz in frequency and packed in the HC-6 /u type holders.
