Abstract

The piezoelectric crystal vibrator, operating by thickness shearing, comprises a vibrating portion (1) provided with a plurality of electrodes (A1, A2) and a support portion (3) formed jointly with this vibrating portion. The support portion is formed as a single body with the vibrating portion and it has the shape of a "haft" extending outwards, laterally, from the ends of the vibrating portion. This vibrator is of high accuracy in frequency, small bulk and can be manufactured easily. It applies in a particularly advantageous manner in an electronic watch in the guise of reference element of standard frequency. <IMAGE>
